I've browsed through this thread, as well as googled myself to near-insanity, and can't seem to find an answer.

I have a Sanyo CE28WN4-B and wanted to access the service menu due to geometry problems. I know this thread is for the HT32744 but was grasping at straws really. I've tried holding down Volume -, Menu and every other suggestion can find and its not working. Thanks.

Try calling Sanyo at 1-800-877-5032. Ask for Jim.
Hope this helps.

Hi, new member here! I have an HT32744 with a problem: It won't turn on, either from the remote or the cabinet on/off switch. My son clicked it on then off real quick, and it just wouldn't come back on. I know it has power, I can hear the hum, and a click when I try to turn in on, followed by another click about three srconds later. It will do this three times, then nothing until you unplug it and replug it in. I just got off the phone with a Sanyo service center, they want $60 up front just to look at it. Is this repair simply a matter of sliding out and in a PC card? If so, I've built many computers, and upgraded/repaired more, it's a hobby of mine. If it is possible I can do the reapair, where can I buy the part? Thanks for any advice, I appreciate it. :)

I assume you're using "PC card" metaphorically? In any case, I seriously doubt you'll be able to repair it yourself. How would you even begin to know what to repair? I'm no TV tech, but I'm guessing not turning on could mean a whole host of things, from minor to major. The way I see it, you have 2 options: pay for the repair, or call Sanyo and try to convince them to let you exchange for a 30746 (read the last couple pages of this thread to get a sense of how to go about this).

Good luck.

I would advise you avoid opening the set. A picture tube is basically a very large capacitor and even with the television unplugged, it still holds a deadly charge.

If you bought it less than a year ago from Walmart, you may be able to return it from what I understand.

Thanks for your replies. I have worked on TV's before, though a while ago. I do know how to discharge one. No, I wasn't using PC card metaphorically, some are built as such. You'd be surprised what you can find out with just a VOM and common sense, though I agree a logic probe would be handy. It was bought over a year ago, so no warranty, and most of the Wal-Marts around here are already out. And yes, the HT32744 and 30744 are discontinuted from Wal-Mart's active inventory, I checked at work last night. Sounds like I bought a lemon. :( Well, guess I have to make lemonade. I have one other possible option to try out before I bring it in and bend over. ;) I did try the whopping it just above the input board to no avail, but hey, it was worth a shot.

My store does have one HT30744 left, I suppose I could try trading even up for it. I'm not sure if it will fit in my cabinet, though the 32744 had 1/4" clearance on each side!

Hello
after reading this thread many months ago i decided it was a good buy well after 7 months the tv just died last night. The screen goes black and loses picture but not audio and then comes back happens frequently.
Should I phone sanyo or just goto Walmart. I dont have the box anymore.

ACKKKKK! I'm having the same problem (all video goes out, not even menus, but sound remains). The odd thing is, when I shut off the set, the flash of retrace lines is visible. Sometimes if I turn the set off and back on, the picture comes back on. Sometimes if I tap the back of the set, the picture also comes back on. But not always.

Even though my HT32744 was out of its short (refurb) Value City warranty, Sanyo agreed to have a local shop fix it. I lucked out -- the shop agreed to pick up/drop off the set for $50 cash -- I consider it a bargain rather than having to lug this monster myself. Unfortunately, after a week in the shop, the problem, which is intermittent, won't recur for them.

If you end up getting yours fixed, please get the details and post them here on the web, so I and others with this same problem can solve it. Thanks.

In my experience, DVI>HDMI produces a crisper, more vibrant image with this set than component, particularly with regards to text. I use a Radeon though, so YMMV.

I agree. I repeat my recommendation for www.cablesforless.com, with this update: my HDMI/DVI cable went bad, and cablesforless immediately replaced it for free, with free shipping, and paid for shipping to send the old one back so they could see what went wrong with it. Great customer service.

Also, see my post # 2324. Be sure to purchase a dual - link cable. BTW, cablesforless is out of stock on the 6' cable right now, but the other lengths are in stock, cheap.

I bought my Sanyo HT32744 June 3, 2005. It has nine days left on the warranty.

Today, when I turned the set on, it seemed to be missing red colors. But over the next ten or fifteen minutes, the reds came back. It's Friday before the holiday weekend, so I guess I can call Sanyo Tuesday. But I'm curious to know if anyone else has seen this problem and what was the result if you have.

I see that Wal-Mart no longer carries a 32" Sanyo HDTV. The Sanyo warranty say they will replace it where I bought it. Anybody know what's likely to happen?

They will probably give you credit towards another tv model.

I bought mine in July 05, and a few days ago I noticed that the red was completely gone. (It was easy to diagnose; the ReplayTV screen saver alternates among red, green, and blue logos.) I cycled power a few times, and no go. Dammit. I turned it off and left it off for a few hours.

When I came back and tried again, I had full color. Been good ever since. I figure I'm on borrowed time; I guess that's OK, since the set was fairly cheap to begin with. You do get what you pay for, up to a certain point (beyond which you're just throwing money away for the sake of throwing money away, but that's a different story).

Are you using component cables? Your Red cable (Pr) might be loose.

This was across the board on all inputs, unfortunately.

I just purchased a HT30746 and got it home, noticed in the store it had some interference, figured it was just the input they were feeding it, same thing at home :(

using xbox 360 in 780p/1080i w/ component cables... just has some lines/distortion if you look carefully, same with component input from dvd player... even get some flickering horizontal lines if you look very closely in progressive mode

time to take it back?

Same thing here. I just purchased the Sanyo HT30746 at Sprawl Mart and I have the same lines in 720p/1080i when using my Xbox 360. When the screen displays dark images I have the jailbars and the small horizontal lines running across. I've also noticed it while using S Video for DVDs. I did turn the brightness and contrast down due to the default being set high and the picture does look a little better. I can faintly still see the lines though. Is there a way to fix this in the service menu?

I was thinking about returning it but I have been reading here that this is a problem with this model. Any known cures?

If I need to I will call Sanyo and see what they can do. Is Jim the best person to talk to?

This was across the board on all inputs, unfortunately.

Earlier in this thread I remember someone saying that Sanyo send out a tech that re-soldered a connection point for their red gun. Sounds like you might have a similar problem - you should give Sanyo tech support a call.

Hello community, I own the Sanyo HT32744 HDTV television. I get my signals via OTA Antenna. The picture and sound seem to be good. I am having one problem and I am not sure if its the nature of the beast or a problem with the set. When I am watching indoor sports, Hockey, and Basketball so far I get a annoying flashing at times. I think its due to the camera flashing in the crowds. My screen kind of blacks. Its irritating to me. I also wondered if maybe it was the source.. But it happens on multiple channels, multiple resolutions. It even happens when I watch the local sports review shows and they show highlights from the game. I haven't noticed this problem on Baseball but the only games I have watched are outdoor. I can't say about football as I have only had it setup 2 weeks. It doesn't happen on non-sports content that I have noticed. If anyone has any insight I would appreciate it. Thanks,

JT

[QUOTE=DBCooper]Well, the red problem never recurred. In the last eight days, every time I turned on the Sanyo, the color was OK. I doubt that calling them today would have any benefit, even though the warranty expires tomorrow. Cross my fingers and hope, I suppose.

I doubt that calling them today would have any benefit, even though the warranty expires tomorrow. Cross my fingers and hope, I suppose.On further thought, I did call Sanyo before the warranty expired because the set has other problems (other than the temporarily missing red.) The Sanyo rep agreed that the red problem would likely return and it was best to take action now. She offered a full credit at Wal-Mart (I paid ~$700 one year ago) but, frankly, it's a huge hassle to return such a heavy set. Also, I had purchased a $200 matching silver stand and Sanyo doesn't make this 32" HDTV any more. Nor are the replacements (any brand) likely to match. After some discussion, she agreed to try to fix it in my home. I listed three things that I neded done:

1. Replace the "red module" (her phrase) that was acting up.
2. Fix the two pale green spots on the screen that only show up in a B/W movie or when they overlap a large area of white. One is left of center and the other in the lower right of the screen, but neither are in the corners. She seemed to think that it was possible to fix them.
3. Re-program the set to add back the QAM cable HDTV tuner capability that was in this model until a few months before mine was manufactured.

They promised to find a qualified repairman and have him or her call on Monday, 5 June.the

I have the 32744 32" tv from WalMart, occasionally on white screens I get a Green Blob, (Kelly on the Ragis show wears white blouses guess where the green shows up) I called Sanyo, they told me that is is a known problem and to take the TV back to Walmart for an exchange (Walmart does not have any more) so I've keep it and consider it a unique feature when the blob shows up!.

I then (in to constant pain) purchased the new HT30746 "New Model" 30" widescreen, I love it, but the Pin Cushions on the vertical center is bowing in. Does anyone have a service manual for the HT 30746 with the service codes? I can get in to the service mode but the service manual for the 32744 and the HT 30746 look different and I don't want to make things worse.

For $478 for the 30" widescreen with built in tuner is a great value, Id just like to tweak it a bit to make it better, so if anyone out here has a service manual and can send me a pdf of it I"d really appreciate it..

One thing that Sanyo did say is that they will back it up with a 1 year exchange at WalMart, and I purchased it on my american express card so that gives me a second year warranty to match the manufacturers 1 year.

Any help would be appreciated, you can email any docs or info to davidk@eaglecanyon.com I"d appreciate it.

It's seems that you have the manual for Sanyo HT30744/27744/32744. If you have this file in PDF format, could you please send me a copy to wyn20705@yahoo.com? I really appreciate it!

Hello. I just bought the 30" Sanyo HDTV, and I noticed that when playing my 360 through any of the component inputs, there is noise in the picture. It looks like vertical bars kind of moving fast across the screen. Also, there's other random noise in the picture. I went to circuit city today and bought a monster cable home theater power conditioner/surge protector, and then bought the monster cable Xbox 360 HD component cables. STILL no change.

I called up Sanyo and they said they have no reports of any such problems, that I should take it back to Wal Mart. The thing is, I just got done taking back 2 TV's in 2 months, and I am tired of it.

Is there someone anyone can refer me to that can come out and repair this problem, because as I've read, it seems that this is NOT an isolated problem. Please help me out, I really need the noise to go away.

Also, if I DO end up exchanging it, what are the chances the next one will have the same problem? Thanks a lot!

lesman,

It's an extremely common problem with this set, and we suspsect it's due to cheap components on the set itself. I'm not aware of anyone that's had it repaired.

Hi guys first post. I just bought the 30 inch widescreen from walmart for $478 too. Im having the same problem. Im starting to think that 360 is just much better with Progressive scan. Is there anything we can do to optimize the picture and the other problem hes describing? Ive already returned one this month, that set was damaged though so thats a different story but I'd prefer to just make this one satisfactory. Thanks.

Figured I'd report back, my 30744 has been back now for quite some time and has logged quite a bit of use (usually a couple of hours a day) since it went to the repair shop for the loss of red issue. Since the IC on the red drive on the picture tube drive board was resoldered the issue has not returned. Anyone with one of these sets and such a problem should investigate this area. I'd veture a guess like the tuner issues that plagued the RCAs a few years back, there might have been a bad batch of solder joints in these sets. My theory behind this is the IC warms up, over time the cooling and warming cycles weaken the solder joints, and eventually the problem appears. It would explain why sometimes the sets will work when shaken or tapped, or work for a long period of time then have it reoccur frequently over a short period of time. I'm waiting for someone to drop a broken one off at a thrift store or sell it at a garage sale so I can experiment in testing the theory that this is the actual problem with these sets.

I've recently played around with the QAM tuner a bit which while nice seems to be somewhat annoying to use since you have to reprogram it if you wanted to use an over the air antenna.

I've been a lurker here for some time...since I first saw the HT32744 at Wal-Mart. I was upset when they discontinued them before I could afford one...

Fast forward about 6 months...I'm in the market for an HDTV, and decide to get a used one...hoping to get lucky.

I find a HT32744 on Craigslist of all places...seller says she has had it for less than two years, $350, no problems. I see the TV hooked up to a $19 DVD (composite video only) and standard coax...and the pic is pretty dang good. Checking out the back it says "Refurb: May 2005." WOW, it was refurb just over a year ago...

I sweat a week waiting on my bonus from work...no one buys it...my wife tries to talk me out of it...I'm not hearing it.

I've had the TV for a bit over a week...Comcast DCT6412 Phase III box. First hooked up to component (pic excellent with DVD and cable) got the HDMI cable today (HDMI to HDMI) picture is even better (though it will not go into Surround sound now/not even an available option/grayed out.) My biggest issue now is when it is in DVR mode (when skipping ahead 30 sec and sometimes changing channels) there is a loud "CLICK" in the audio...wasnt there with component connection. Any ideas?

Also a bit annoying, I find myself switching pic shape between channels...display seems random, but to keep 1080 broadcasts widescreen, I have to select "full." Other channels either display correctly (4:3) or stretched, seems randomly...only slightly annoying, but would appreciate input, if anyone has any ideas...

Hoping since the TV was refurb so recently, some of the glitches will be worked out...knock on wood.

Thanks for all the info, past, present, and hopefully future!!

Recently I bought a Haier air conditioner that has a remote. I did not want one with a remote but was unable to find one. Several stores had the 5000 btu without remotes, but nothing larger.

Yesterday, my wife and I got into a "discussion" about the settings on the air conditioner. I asked her why it was on the fan setting rather than on cool. She said she had not touched the air conditioner. This "discussion" lasted a few minutes before we agreed to disagree.

You may ask "why post this in the Sanyo TV thread?". I bought the 27" version (HT27745) last October. It turns out that some of the buttons on the Sanyo remote in the TV mode ALSO changes settings on the Haier air conditioner. I found out I could change all the a/c settings with the Sanyo remote. Strangely, the Haier remote does NOT operate the TV.

Gotta love technology.....

Now that's funny...I'd cover the IR receiver on the AC with tape or something, since you didn't want the AC to have remote anyway...

The Sanyo Television remote must be using frequencies that are similar to the one programmed into your Air Conditioner. If you hate screwing with your air conditioner everytime you change channels or change volume, you might want to cover the sensor.

there's an echo in here... ;)

Sorry if I sounded like a copy cat

I have the 32" 32744 that I bought from Walmart in February of 2005, so the 1 year warranty is over.

I've just recently noticed where a green tint will come over the screen, sometimes it will go away on its own, sometimes I need to smack the TV then it goes back to normal. It sounds very much like Yrly's TV which ended up being a mis-soldered IC711.

At this point in time, would Walmart exchange this TV? From what I've read of this thread, they dont' have a 32" 4:3 HDTV anymore. I do have the original receipt, but I could always misplace it and remember that I actually bought it in August 2005. Or, would Sanyo fix it at their cost?

Try calling Sanyo - none of us can tell you what Sanyo or Walmart will do.

Hi, I recently purchased a HT30746 and i love it. I haven't noticed any problems luckily except that the picture is slightly tilted to one side. I am wondering if this can be corrected in the service menu? and if so, by what option? Sorry if this has been answered, i searched but have been unable to find an answer, or even a similar problem

Thanks

Try calling Sanyo at 1-800-877-5032. Ask for Jim. I had to replace my 30" that had green tint problems. Jim from Sanyo was very helpful and I used his leverage to get a new 30" from Wal-mart.

If it's still under warranty, force Wal-mart to exchange it for a new one. If it is out of warranty tell Wal-mart you paid too much money to have this kind of problem and you want a replacement.

i have recently put the "SANYO 30" Wide Screen HDTV w/ Built-In ATSC Tuner, HT30746" on layaway at walmart, the main reason why i am getting it is to use when playstation 3 comes out to hook it up via HDMI. this is the cheapest high definition set that has an HDMI input so it seemed like the best way to go. also it says on every website that i look at that it has 1080i but in walmart on the tag it says that it's a maximum of 720p? which is correct? i still can't decide if i made a good choice orr not after reading all these posts

It's a 1080i native set, although I don't believe it's truly capable of 1080 scan lines. I believe I read somewhere that it has 800 scanning lines, although I may be wrong about that. It is capable of displaying inputs of 480i, 480p, 720p, and 1080i and upconverts everything to 1080i (see http://www.sanyo.com/entertainment/televisions/digital/index.cfm?productID=1240). Note that it won't be able to display 1080p input (such as PS3 is capable of).

At any rate, you're going to be paying more for the Playstation 3 than you will be for the television - that seems backwards to me. I think you'd be happier if you saved up and got a larger screen, preferably with 1080p capabilities (although the price for this can be very high). If cost is a big issue for you, you should be able to find 37" 720p LCD sets for around $1,000 nowadays and 42" 720p plasma sets for arond $1500. Sam's Club & Costco also offer a 50" 720p plasma television by Vizio for less than $2000 - I have it and can definitely recommend it for the price.

The PS3 would look good on this Sanyo, but it wouldn't be breathtaking.

thank you for the quick response. ok here's the deal, i already have the 600 bucks saved up and in the bank for november 17th when ps3 comes out so that's taken care of. but there's no way i'd be able to save up to get a $1000 set, this one is only 478. and yeah i know it wont be able to handle 1080p but i figure 1080i isn't too shabby especially compared to my current tv which is a pile of junk.

the only other one i considered was this one. a Philips 30" Widescreen HDTV w/ Built-In ATSC Tuner, 30PW9110D/37.

it goes for $526 at walmart but i really couldn't tell if this one had any adavantage over the sanyo and the sanyo was 50 bucks cheaper. they really look almost identical to me...

High motion games work best on progressive scan due to the fact that all scan lines are painted over the screen in each swipe of the screen. With interlace, you've got fractional second delays in the screen. This might not produce a smooth flowing picture and you might notice that on games that are rendered at 1920x1080 resolution. My brother has an Xbox 360 hooked to his DLP television which is a native 1280x720 progressive scanned set. Even though the resolution is not full high definition, the smooth flowing video makes up for the loss in sharpness.

there's no way i'd be able to save up to get a $1000 set, this one is only 478.

OK, do this. Instead of spending the money on the set, pay a friend to wait in line with you for a PS3 and buy one with this money. Then, sell it on eBay for $1,000+ and buy a better set :) I'm just letting you know that for the truly mindblowing experience you want from your Playstation 3, you'll need a better set than this one. The set is a good deal for the money, but you still get what you pay for.

Just wanted to Pop my head on the ones who got this years model.
I have last year's 28inch. The tube seems the same as my model.
I know people with LCD, and Plasma (not 1080P's) who say my picture is every bit as nice as their pics. I don't think they were being polite (I hope).
If this is for a Bedroom, or Dorm/1st apartment, it is a great low cost/high quality solution. To Me (who has only seen a few HDTV's other than my own) the picture is awesome.
Remember, the closer you sit to your TV should be a factor for how big your screen should be. You should not go for the huge sets if your viewing distance is only a few feet.
Last tip for this set, Have a dolly! This is a heavy set! I had to carry my 28" up to the third floor!
HDMI ::Sigh:: I should have waited...
Mark

No matter what I plug in the back of the set It doesnt see it and I get a message no inputs detected.

Anyone have a similar problem? It is almost 2 years old.

Thx

Hello,

Sorry if this has been posted here before (this thread is after all 85 pages long! :D

I have an HT30744 and there seams to be a audio/video sync delay. I thought it just might be my DVD player (it upconverts to 1080), but I dismissed this when I watched the TV carefully and realized that EVERYTHING had a sync problem.

My proof of this sync was when I was in Wal-Mart again. I saw wall full of the TVs playing.

Now, I understand that there are a lot of anomalies that can cause all the TVs to refresh at different rates. But, from seeing all the Wal-Mart TVs, EVERY TV was refreshing in sync. Except the HT30744 model. It looked to be 1 frame off.

I went to a few Wal-Marts. ALL the TVs refreshed in sync, again, except the HT30744. Refreshing a full 1 frame behind.

I did some tests (I am a video editor). I created some files for my TV to play. 1, regular, and 1, a frame outta sync. To my suprise, the file I created that was 1 frame outta sync played in perfect visual sync with the audio.

I've concluded that this TV does in fact have an audio/video sync issue. It plays video back 1 frame too late.

Can anyone suggest anything for this? Can any of the service options fix it?

If you can notice something 1/30th of a second out of sync, then you are better than the rest of us I'd imagine. I highly doubt that's something that's going to be fixable in the service menu.

Figured I'd report back, my 30744 has been back now for quite some time and has logged quite a bit of use (usually a couple of hours a day) since it went to the repair shop for the loss of red issue.

Are you certain that it was IC711? I am having the green tint problem, so I popped open the tv and resoldered the IC711 chip. The green issue has reappeared since then.

IC711 was the one they resoldered. It is the chip that drives the red gun of the picture tube on the picture tube neck. There are three similar chips if I recall, one per gun. I discussed this with the repair person. Contrary to what it appears the set isn't going green, it's losing the red. The picture will appear green with no red. The red is still there but it's not strong enough to produce a vibrant red needed for the proper picture. After explaining to the repair person that rocking the set would restore the color, or tapping it or sometimes unplugging it, we pretty much reached that a solder joint somewhere was at fault. I actually had to have them take the thing in until they could get the problem to replicate while it was powered on and correct it. I'd assume it would be possible for that chip to go bad entirely, possibly as the result of a solder problem (I was explained something to that effect in regards to an RCA TV I had repaired a couple of years ago). Still it has been 6 months the TV has been in use since then and the problem has not reappeared, this TV gets several hours of use per day.

Well, I may have spoke too soon. Besides the one time that it went green right after I soldered it, it hasn't done it again since then. I have my fingers crossed that it did indeed fix it and it won't come back. Thanks for passing on the information yrly! :)

Might want to check the solder job again just to be on the safe side or at least you'll know where to look should it happen again. Apparently the factory solder job looks OK visually at least based on what he told me, it was not until I described it in depth that the repair guy combed it over again and it was then that he tested it over a weekend, found the apparent problem after the green issue appeared and soldered it. Again though so far so good been 6 months here and it has not happened since he did it. I've been using this TV in the kitchen where it's used about 4 hours (possibly more) a day on average so it has logged a good bit of time since the repair. They wave bath solder things these days and though it might look physically good it might not make good contact. Hopefully this proves to be the root of this problem, not just for you but for others with this problem especially those a way out of warranty with no recourse. As I say when it happened and I called Sanyo, they didn't seem to doubt that what it was could be fixed and since I'm in close proximity to an authorized repair center never had an issue with having them look at it. I'll keep everyone posted should it happen again but so far so good. Of course knowing this I've been combing thirft stores and the curb hoping someone ditches one with this problem as I wouldn't mind having another one of these for the basement.

On a side note have you noticed any difference in the picture since doing this? Mine had a tad more of a red push after this repair which I had to dial down a bit, leading me to suspect that this problem was not only in the production but was compensated for in the service menu at the time these TVs were set up. Also is your set's QAM tuner enabled (mine is), I've been combing the posts to see if this issue was corrected around the time the QAM tuner was disabled.

Well good luck with your set, keep us all posted on the results, and again I hope it works out for the good, because when it's working it's really a pretty nice set.

Well, I bought the HT32744 in November 2005 and started experiencing the "green blob" almost constantly after a month or two. Then a couple of weeks ago, we started losing all the reds. As described in this thread, I would move the TV a bit and it would disappear. It then started occurring quite often. Pretty much, that was it as far as I was concerned. I called Sanyo and they just told me to return it to Wal-Mart. So we hauled that heavy SOB away. It took a little talking to, but after the associate read the warranty information they took it back (with original receipt of course) and we got our money back.
We ended up getting a 32" LCD Vizio L32HDTV which we are extremely happy with now. Between the exchange, the new TV and extended warranty, we paid under $350 for the upgrade.
The way I saw it was if these things were happening before the first year was up, who knows what else is to come.

Just thought I would post my experience here.

I've been having the same "loss of red" problem (on my HT32744) that so many others have been reporting...we'll be watching as normal, and then the screen takes a blueish-green tint, as if all the reds have gone out.

I called the Sanyo service line, told them my problem, and ended up getting connected to a "Mary Jo." She was extremely helpful, and told me a "digital module" had gone bad. Even though I am WAAAY out of warranty (bought the TV in Jan '05, and it has an August 04 manufacture date), she offered to send the needed replacement part to a local repair shop and to pay for the needed work.

I'll let you all know how it goes. If you are having a problem, it couldn't hurt to call Mary Jo at 1-800-877-5036. Very nice, and very helpful.

I'll say this for Sanyo...their TVs are kind of cheaply made, but their customer service is better than most.

She was extremely helpful, and told me a "digital module" had gone bad.

Hmm, digital module probably means an IC... anyone else try resoldering IC711 which is part of the drive for the red gun of the picture tube? I'm wondering if this is the "bad" part. Report back and let us all in on what exact part they replace if they list it on the repair receipt, would probably be helpful for those who would attempt to do a repair themselves. If indeed it's IC711 we might have the lead on what exactly causes this problem. My set hasn't gone green since it was resoldered in January which is only a month or so shy of the period from when I bought the set to the time the problem first appeared.

Hrm, disturbing. And I had heard Sanyo was supposed to be among the best (if not the best in reliability). I'm seriously looking at the 30" model right now...

so very disappointed in my 800$ Sanyo HT32744 & walmart...less than 2 yr old and blinking black when a lot of white is on the screen...started a week ago and getting worse...I contacted Sanyo today to give them a week to get it fixed...I predict next Monday I will kick the &!*# thing and have to pay to have the 150 lb beast hauled off...my next TV will not be HD, Sanyo or from walmart

my next TV will not be HD, Sanyo or from walmart

You give up on an HDTV because the cheapest one you could find broke on you after two years? That's like buying a Chevy Cavalier, having it break down, and decide you're going to stick with a bicycle from now on.

If your next TV is NOT an HDTV, I bet you'll be kicking yourself in two years.

"cheapest"? ...If my brand new cheapest car crapped out after less than 2 years, I would feel the same about that make and model...I remember the time when quality meant something...I just don't think the HD "wow" factor justifies the $...I need to research before my next buy to determine what brand & model has best chance of providing at least 5 years of satisfaction...my previous RCA 25" colortrak console model gave me 20 years with no problems...quality, where has it gone?

Yes, the Sanyo HDTV is the cheapest HDTV on the market, and it was when you purchased it as well. The Sanyo HDTV does not have much "wow" factor - get a larger screen from a high quality brand and you'll see the wow - just go check out a Panasonic 50" plasma or the Sony SXRD.

HDTV is not quite mainstream yet, so there is still a premium price involved, but prices have fallen fast. You can get a 50" HD Plasma set for less than $2,000 now and 30"+ HD LCD sets for less than $1,000.

It's one thing to say you would never buy Sanyo again, but it's another thing to say you will never buy an HD again. Already almost all primetime network television is in HD and almost all major sporting events. There's no reason (except cost) at this point in time to buy a new TV that doesn't have HD capabilities.

I'm thinking about exchanging a defective HT30744 set back to walmart, its 10 months old, but I have my original receipt. Not sure what to do right now. The TV has the bad wavy component inputs, the audio and video sometimes doesn't sync up when using the digital optical output, and recently, the tv will just go black for minutes at a time....but will mysteriously come back on.

Can't find a definate answer in this forum, but from what I understand....

The new HT30746 is somewhat inferior to the HT30744, so I'm afraid that that set will crap out on me too in a few months.

Other option is getting the DP32746, Sanyo 32inch LCD, but it'll cost me an extra $400 bucks to upgrade to this. Is it worth the extra cost?

Or do I just keep this set and hope that it doesn't just go completely?

I'd like to keep the QAM tuner function and I don't think any of the other models at walmart has this.

Any opinions or ideas? Thanks in advance to all who can help.

I owned the HT27745 (the 27" 4:3 model HDTV) AND the Sanyo LCD model DP32746 before I got my Sony KV-34HS420. I would say that if the HT-30746 is as good as the HT-27745 I would definitely get it over the LCD or any other CRT based HDTV. Although I ended up with a Sony KV-34HS420 I do feel that the picture quality was better on the HT-27745, I mean, the Sony is impressive but there is not as much of a wow factor as the Sanyo. Btw, unless you really do not care about picture quality I would HIGHLY advise against getting the DP32746, LCD's make horrid TV's, the Sanyo definitely is good, for an LCD, but, I was much happier watching ANYTHING on my old CRT SDTV

Well I see some of you are quite dissapointed with your Sanyo, but I must say I am pleased with my $300 HDTV(32744) so far. I have learned alot about the HDTV format, much more than I thought I knew and it didn't cost me alot of money. I could have spent $1000 or more on a tv that may or may not have had the capabilities I had expected of all HDTVs. By the time I outgrow this one or it starts to fail on me I'll know more and I'll know what to look for in my next set besides just being an HD set.

With all that said I am now ready to try and make the most of this heavy thing. If any of you are experts with this tv I could use some tutoring with calibration(service manual??) and ATI component/powerstrip use. If someone can help me with this or even point me in the right directions thanks in advance.

I read that and I am actually printing it out right now but I was hoping to get some input from those who have actually used one of the Sanyo CRTs

Still looking for a HT32744 service manual too. My contrast was indeed at its max but I think my picture could still use a little fine tuning.

Hello all. My tv I bought refurbished (HT32) back in November '05, and now at random times the red seems to go away like many other users have reported. What do I call or say or do so I can get Sanyo to fix this? I dont believe i have my Value City reciept anymore because it is well past the 90 day original warranty. Any suggestions or maybe tips to fix this problem will be great

Hi Hlx!
Unlike many here when my set lost the red last December instead of attempting to get a replacement from Wal-Mart I called Sanyo and asked if it could be repaired. (Glad I didn't too, the new model's picture isn't as good and I'd have had to wait for it to arrive, squandering the other half of the remainder of my warranty). I'm in fairly close proximity to a place that will work on them and Sanyo was willing to attempt to repair it. Long story short they ended up resoldering IC711 on the picture tube drive circuit board. Reds have been fine since January now and the TV logs a lot of use. If you scroll up you can read the whole story behind it.

I have had the 32744 since Sept of last year, so, I'm still in the return window to get store credit .. Im taking it back because I started with the green blob, not I"m watching the green people from He** sometimes it comes on fine, but then all of a sudden the red seems to away Sanyo didn't have an option except to take it back to Walmart or some "Appliance repair shop" for a repair, well, I know the shop and I would not let them touch my filter in my fridge let alone my TV... so, i'ts going back... Now I have to start all over again trying to decided on what TV to purchase now! Oh what fun this is!

I returned the 32" 32744 yesterday (11 months old) because I lost the reds completely, the guy at the walmart said that sanyo was the big return item for TV's so, I decided that since my 30" is stil in the 90 day warranty period I'm taking it back today and get a full refund rather than store credit (it's going to take me for ever to use the $633.00 on the 32") I just figured with all the comments and the fact the 30" has terrible bowing I'm not going to screw with it anymore, it's going back.

I see that circut City has the polaroid 32" on sale for about $750 any of you tried one yet?

Did anyone by chance save the thread about using the Sanyos as a HTPC monitor? I can't seem to find it.

I was just trying yesterday to get my 32" workwith 1080i over dvi/hdmi...here is what i found in the archive: http://archive2.avsforum.com/avs-vb/showthread.php?t=414867&page=3&pp=30

First off PLEASE don't suggest TV's I should have or should buy.

I have a SANYO FS model# HT30744. I made sure the 360 component cable was set to HDTV, set the 360 to 720p. When playing games I get these weird white faded looking lines running down the screen. There very noticeable on the saints row demo, but barely noticeable on COD2 & Oblivion( there still there, just not as noticeable ).

Any help would greatly be appreciated?

If you read this thread or even briefly skimmed through, you would notice that this is a common problem on the component inputs. There's nothing you can do to fix it.

It only does it when playing in HD.

So does mine.. like Shink said, it's a common problem.
If you look hard enough, you'll notice on non HD stuff too.

Yeah, I've had this TV for a year and a half or so and I've dealt with the wavy component input problem ever since I've had the TV. I find that it's worse in 1080i than 720p.

It only does this for me in the saints row demo. COD 2, OBLIVION, & HM: BM all play fine in 1080i. The scanning line is still in those games its just very, very, very faint, pretty much not even there.

Thank you!

After a year and a half my HT30744 started to show the "green glob of death". I saw on this forum that Sanyo knew about this problem and were helping the owners get new one from Wal-Mart. I called up Sanyo and they were very helpful. I even went to Wal-Mart with the new information and I walked out with a brand new set. I must admit it wasn't easy and the Wal-Mart employees didn't seem to happy that I wanted a brand new TV from their stock. But as I said I walked out with the TV minus the box and the manual.

Thanx to everyone for sharing their experience on the defective HT30744 and how to return it to Wal-Mart.

:)

I picked up a HT30746 today, at walmart, everything looks good except some very notiable overscan horizontally. I've scnned this thread searching for a service manual to fix this with, but it seems no ones' got one.

Anyway to fix this issue?

I have a copy of the service manual for that tv.. I returned mine because of the vertical pin coushin was terrible.. but if you would like a copy of the service manual send me your email address to davidki at yahoo.com I will send it to you it is about 5 mb file.

Is anyone here using an Nvidia card with their 32" 4:3 Sanyo set via DVI/HDMI? I'd like to reduce the amount of overscan I'm getting (losing the taskbar on the Desktop) through Windows leaving the service manual tweaks as a last resort.

With their latest drivers, Nvidia has a cool application that allows you to resize the desktop to reduce overscan/underscan. However, I think it's geared towards widescreen TVs as when I start off in 800x600 resolution and use the tool, I end up in something smaller than 1280x720 which is a widescreen resolution. As a result, everything gets squished horizontally and everything looks really skinny.

I can click on the "Pix Shape" button on the remote, but it gives me the black widescreen bars on the top & bottom when in Letter Box mode. That works great for widescreen movies, but it's not what I'm looking for when I'm in my front end application (Meedio).

Any ideas on how to tackle this? I'm surprised I wasn't able to find anything on this topic in my searches.

Thanks,

Well, I got one of these from my walmart last weekend. My set suffers from the crooked image that other(s?) have reported. I'll be trying my hand at a second set, I think. because the PQ wasn't that bad, but the slant was miserable. I was using it with my 360, as well as an htpc gpoing from a GeForce 6150 Via DVI/HMDI. I fixed the overscan pretty well using the service manual, but the slant was just in excusable. I may return this and just ask for a refund. But, my Question is...

What are my other options around this size, around this price range?

Actually the problem with my 32" was it turned Green.. very green... then, I had a 30" HD set in our bedroom, that one was still in the 90 day return warranty, I had just noticed in the 4:3 mode the bowing to the middle on each side of the picture that I could not tweek out... .the PQ looked great, but I just could not get use to the bowing in the SD mode, so, it went back.... 1 week before the 90 days was up, good thing because I still have a bout $600 on my gift card from the return of the 32" it's going to last me years for the amount of stuff I buy at WM!

I actually replaced my 32" with a Sony 40" lcd, and I think I am going to replace the one in the bedroom with a 32" LCD I don't play games with them mostly just watch OTA HD and DVD's

I picked up one of these sets (the HT32744) at Value City about 10 months ago. It was a pretty random find and at the time, I wasn't even looking for an HDTV, but the price was extremely reasonable (under $300). It has since become my main television, as I just don't have the cash right now to shell out for a nicer, more expensive HDTV.

Well, I've been having problems. The set, at this point is pretty much useless. Here's been my issue:

About two weeks ago, I noticed that colors were slightly shifting...it was very subtle at first and didn't even happen all of the time. I changed the scan velocity to "OFF" and that seemed to do the trick. I moved a little over a week ago and just began having problems with the set the past few days.

First thing that started to happen is that everything would kind of turn green, which led me to believe that the red channel was crapping out. Turning off the set for a bit and even unplugging it and turning it back on would usually get it back to normal and it was isolated, so I didn't freak out. The past two or three days, though, have been horrible.

I can't watch the set for more than 15-20 minutes without it turning the green color and sometimes, if I wait it out, it will correct itself. The new issue is even better...after turning green, sometimes the picture will then start blurring and get very dark to the point where you can't see anything.

I've noticed a few things fix the problem - 1) Turning the set off and turning it back on, 2) time and 3) slightly smacking the set will set the colors normal SOMETIMES. Sometimes, however, turning it off and turning it back on does nothing and smacking it just gets me upset.

Does anyone know how much a professional might charge me to take a look at it and possibly repair it? I know nothing about TV repair or how much it would cost, but my hunch is that it'll cost me more to fix than I paid for it.

I can't afford to buy a new set right now and I'm so upset that I've pretty much written it off, so I'm not against trying to repair it myself, but given my repair knowledge level, that might just be pointless.

Read the last four or five pages in this thread. People have isolated it down to one solder spot coming loose (for the green problem). It's worth calling Sanyo as well - worst case is they say tough luck, but they might set you up with someone to fix it as well.

Nickbrutal

I have that same problem that you have, it sounds like.

(Shink, thanks for the advice on the solder problem!)

Here is what I have found for a "non solder" fix, at least for me.

After the TV is warmed up, the problem seems to go away

I have gone weeks and even months without the problem re-occuring. I even took the back of my TV off, looking for a screw or some other loose connection.

When it happens, I can gently (or maybe not so gently) rock the TV back and forth and it will suddenly go back to a perfect picture.

It seems that it might take 2 or 3 times, and the picture will stay perfect for the rest of my TV session, even if it all day saturday.

I have also found that a frozen picture with a lot of BRIGHT WHITE seems to bring the picture back without any rocking.

I really like this tv, and as most of my TV is still SD, this TV is perfect, and DVD's look great too.

I am hoping that the TV will last for a year or two more, then I will get a LCD or Plasma TV.

Also, that gives the industry 1-2 more years to perfect LCD/Plasma technology (I really want to see a 55 inch LED backlit LCD display!!!!).

Also, that gives Dish Network a year or two to get their stuff together fon DVR HD TV!

Hope some of my "non surgical" methods help you out.

I had the 32" that turned in to the big green blob, finally it would only stay about 15 minutes before it shifted to mostly green...

The folks at Sanyo seem to know that there is a "Big Problem" with the Green, perhpas if you call them, be firm that you know that there is a problem, tell them you know that Walmart stopped selling the unit because of the issues,perhpas they will help..

I took back my 30" unit also, I just don't like how they handled the issue for the 32" and I wasn't about to fight nd deal with them on the 30...

But, I'd call Sanyo, be firm, tell them that you know that they know that the tv is defective and you want it fixed...

SEe what they say.

I was the one who took it locally to be repaired, I'm pretty sure Sanyo allowed it because there was a local service center. IC711 was the IC resoldered, the red drive on the picture tube drive board. Is this the actual problem? I dunno. The symptoms seem consistant with that of a bad solder joint, that being rocking or turning the set on and off fixing it. The IC probably heats up and the thermal cycling of the on and off cycles brings the problem to the surface. I had this done back in January, I've now had the set running longer since the repair than I did before the problem started appearing, and it has not gone green since. If you take it in, alerting them to this would probably save a bit of work trying to find it.

Are you sure the technician didn't do anything else? I had my friend resolder IC711 (he is an Electrical Engineer) and the green problem is still happening for me.

Well, I called Sanyo as suggested and although the wait was long, they were kind of helpful. They said my TV was still under warranty and that I could return it to a Wal-Mart, let them know the problem, and they'd be able to call Sanyo with the serial, and then swap the model out for the one that replaced it or give me a store credit for the price that the TV was last sold.

However, she told me the model that replaced the HT32744 was the HT32546. As far as I can tell, that's a standard definition TV which doesn't really help me out, as I purchased the set specifically because it was HD.

Could the rep I spoke to have been mistaken about this replacement model? Worse comes to worse, I can a reasonable amount of store credit for the television and just pay the difference for a new, better model. I just want this exchange to be as easy as possible.

EDIT: Anyone know anything about the DP32746 that Wal-Mart sells versus my currenty model?

First off, I"m not sure if you said if you were the original purchaser of the TV or not, (one person said they had bought one art a greatly reduced price) and that may be an issue in trying to return it to Walmart without a receipt!

Walmart has a 90 day return for cash, then it's store credit only (that is what happend to me)..

There is no 32" replacement at Walmart for that TV, I was in the same boat as you when I returned my 32" I still have $500 + in store credit on the card..

If you do not have a receipt, I'd just tell them that the receipt is not an issue and that Sharp told you to return it to them for a replacement (which they do not have) or credit.. I think the price I paid for mine was $577.00 and I think that was the last sale price they had.
Good luck, keep us posted

I'm in a weird position, as the TV works SOMETIMES and is also, at the moment, my only TV. Price is an issue and I don't know what kind of position I'm in financially to upgrade, but I think that's my plan. I might wait a few weeks before I attempt the return, get the credit, and purchase another display.

WEll, if it dies completely (which our did, everything eventually stayed green).. your out of luck after the 1 year warranty from Sanyo... so, if you want to gamble with it.. that's up to you but you have to ask yourself.... Do you Feel Lucky? With the money you get back from the 32 you can purchase the 30" for less, and you would start over with a brand new TV and a brand new warrranty.. watch the set for up t0 90 days and see if it turns again, if so, just take it back to Wallymart for another refund!

I didn't feel lucky, and after this tread, not many people do!

Good Luck..

And also note that if you get stuck with a gift card, you can usually sell them on eBay for 90-95% of their value. Helpful if you don't normally shop at Wal Mart.

I'm going on 2 years with my tv 32" (it is my primary one so it sees lots of use) and I have never had a problem with it....

Amigo-2K..........I have had the HT32644 set for a year now, and we keep it on aprox. 20 hours a day.......The set has run flawless and has a "super" picture.........I did have the green blob located in the upper right quarter of the picture , due to have put a small stereo set on top of the set.....The total fix was to turn the set off and back on one time........I have had excellent use of the set, and no problems........I guess that we lucked out, and got good sets......I wonder how many "good" sets are out there ??? Dplugs39

All the tech did was resolder the chip. I suppose depending on what happened the IC itself could go bad which is a possibility. Back when the RCA TVs had the bad solder joints in the tuners I was informed that if you repeatedly turned the set on and off or unplugged it to temporarily resolve the problem is would eventually ruin one of the ICs, I eventually had that TV fixed after pestering RCA until they picked up the bill. The basic scenario was this. I called Sanyo, who said I could exchange the set (it was under warrany at the time), or I could have the service center service it. I didn't feel like lugging it in myself and probably would have been offered store credit for the $275 or so that I paid for the TV to begin with, so since they thought it was fixable I called their repair shop, which is a large service center in the area that covers many brands. I had them take it in for service. Tech didn't find anything immediately wrong in fact if I recall he had to leave it on for two days to get the problem to replicate, so I called him explaining the problem, how rocking the TV or tapping it at the top would cause the reds to come back. He then believed that it was a solder problem somewhere. He said he combed the set over for bad solder joints and didn't notice anything immediately out of place but when through it again and then resoldered the IC. After doing so the TV then worked. It has worked fine ever since. The problem originates after all the other stages (which is why it appears on all inputs). But given how these things are wave bath soldered if the IC can be poorly soldered I'd venture to say almost anything on that board probably might be as well, perhaps the solder temp wasn't hot enough. I know at this point in the game, out of warranty, if I ran into color loss problems I'd simply redo the entire sections of the picture tube drives for whatever color problems there might be. So far its been the red, but we're only about two years on here, who's to say other problems may not develop down the road, only time will tell.

Help, Our HT327444 needs help. Initially I thought I was only viewing shades of Green and light blue. This started about a month ago. We have had the set about a year.

I think we have two options: repair or replace.

I would like to make a simple adjustment. After reviewing the various forums and threads I see that the television and video world has passed me by. I think the picture tube still usees red, green and blue guns to develop the picture. However, as I read thru the different postings I can see that all else has changed.

Our symptoms seem to change as we change channels and Tv set inputs. The TV picture is derived from a DirectTV H20 receiver using an HDMI cable to connect them. In addition I connect a camcorder using S-video video and a Sylvania DVD with composite video. We do not have OTA where we live. We have a good B/W pix by adjusting color to "0" on the manual adjust.

I would like to repair it if I can make a register adjustment per the manual I donwloaded, but that manual is for the 30" set. .... has anyone used this manual info successfully??

Maybe I can adjust the drive/screen levels (....perhaps a register setting ) to correct our troubles?

Can I turn off each gun to see if any of the three guns have failed?

Last option is to give the set back to Walmart and go for the exchange. But I really like the set except for color troubles.

Thanks

Help, Our HT327444 needs help. Initially I thought I was only viewing shades of Green and light blue. This started about a month ago. We have had the set about a year.

I think we have two options: repair or replace.

I would like to make a simple adjustment. After reviewing the various forums and threads I see that the television and video world has passed me by. I think the picture tube still usees red, green and blue guns to develop the picture. However, as I read thru the different postings I can see that all else has changed.

Our symptoms seem to change as we change channels and Tv set inputs. The TV picture is derived from a DirectTV H20 receiver using an HDMI cable to connect them. In addition I connect a camcorder using S-video video and a Sylvania DVD with composite video. We do not have OTA where we live. We have a good B/W pix by adjusting color to "0" on the manual adjust.

I would like to repair it if I can make a register adjustment per the manual I donwloaded, but that manual is for the 30" set. .... has anyone used this manual info successfully??

Maybe I can adjust the drive/screen levels (....perhaps a register setting ) to correct our troubles?

Can I turn off each gun to see if any of the three guns have failed?

Last option is to give the set back to Walmart and go for the exchange. But I really like the set except for color troubles.

ThanksMy TV had the same problem. Called Sanyo up, they said a tech will come by my house. He came and all he did was replace the 'digital PCI card' in the back of the TV. Now it's back to normal excluding the annoying overscan and the tilted screen issues.

I took my TV back to Wallyworld 1 week or so before the 1 yr exchange warranty was up on my TV, but Sanyo had no repair options available it was an exchange oppertunity with a non HDTV version or store credit.. do you guys know how long it takes to use up $633 in store credit at Wallyworld.. well I'll be going there for years.. but, I took the tv back and replaced it with a Visio 32" from costco ..the now are $699 and it is great....

You can sell your store credit on eBay.

Hi,

I'm missing about a half inch of picture on the right side of the screen from HD broadcasts off my cable box and from XBox 360 games. How should I adjust my settings to remedy this problem?

Thanks.

Just started having this disappearing red color issue and wondered if the others like "yrly" had this problem with both the HD and SD tuners.Makes no difference if I use cable box SD or OTA HD with my silver Surfer antennae,the green (or more accurately,lack of red) issue looks the same and is at least for now curable by turning set on & off.I got extended warranty and would like to get an idea of what needs replaced outright,not just temporarily "Fixed". Are we talking shared picture tube or what?I don't know much about dual tuner tv sets. Thanks
PS I'd be curious to get an actual count on number of people who had this problem.Seems to me the phrase "Manufacturing Defect" certainly applies.

There is only one picture tube. I think it has been confidently nailed down in this thread that one of the solder point is the problem. Do a quick search on this thread for solder and you'll find it.

First off, I"m not sure if you said if you were the original purchaser of the TV or not, (one person said they had bought one art a greatly reduced price) and that may be an issue in trying to return it to Walmart without a receipt!

Walmart has a 90 day return for cash, then it's store credit only (that is what happend to me)..

There is no 32" replacement at Walmart for that TV, I was in the same boat as you when I returned my 32" I still have $500 + in store credit on the card..

If you do not have a receipt, I'd just tell them that the receipt is not an issue and that Sharp told you to return it to them for a replacement (which they do not have) or credit.. I think the price I paid for mine was $577.00 and I think that was the last sale price they had.
Good luck, keep us posted

Mine died this week. It started popping and clicking. Sanyo refused to repair it. They said I would have to take it back to walmart. Luckily for me my wife saves everything. Manuals, receipts etc... I took it back to the store. They gave a lot of hassle and tried to make me play the you must get it repaired by Sanyo game. They then called Sanyo and got auth to return it. During the process I heard a CSM tell the person doing the retun not to do this anymore and to leave it to the burden of the customer to get fixed. Amazing... I was then shocked when they gave me cash instead of making me take in-store credit. Believe me I took the cash and ran. I am disappointed because the TV was a good TV before it started having problem. I paid less then $500.00 for it so now I have to try to find something comparable and I doubt that will happen today for that price... Anyone have any suggestions on a replacement? I am going to add some cash to it... For say $700.00 thats between 27 and 32 inches? Thanks,

I had the 32" TV and the green problem. It wasn't that bad (happened one a week for an hr or so), then it got a lot worse being proper colour was unusual. I called Sanyo and they said that with the serial #, it was still in warranty until Friday and to take it to Walmart. I couldn't find my receipt and only my credit card statement with the TV on it from May 05. I called Walmart and they said that the warranty is for 1 year and not longer. I called Sanyo and they said to go with the TV and if they won't exchange it for a similar model to get them to call Sanyo.
I went down and the manager gave me a bit of hassle, then said to get the exchange. THe only HDTV CRT Sanyo was the 30" widescreen for $480 (I paid $680). I didn't want this so they gave me store credit so I could purchase the 32" LCD Sanyo from them.
All in all I got the TV that I wanted 1-1/2 years ago for a lot cheaper than I would have thought.
Everything looks great on this replacement, great colours and contrast and the computer is now no hassle or bad overscan.

There is only one picture tube. I think it has been confidently nailed down in this thread that one of the solder point is the problem. Do a quick search on this thread for solder and you'll find it.

I did read all thru & while it seems certain a good number have had this flaw only YRLY had it serviced by an authorized repair center & 1 other person MAYBE had it fixed by a friend following YRLY's advice ,but was not at all certain.While the solder issue seems likely,it's not at all unusual for the picture tube to expire shortly after the manufacture's warranty expires.(Had it happen on the first TV I ever bought and that's why I always fork over for the extended warranty).

So,who other than YRLY has had this repaired?

This sucker is heavy and I'm not about to drag it halfway across the state more than once.
Thanks

I'd been having the same problem so I wanted to give it a look myself. I opened up the TV (took the back off) and went looking for the solder spot yrly was talking about. To my dismay the chip was soldered on perfectly and that obviously wasn't the problem. I examined all 3 chips and found nothing. The chips did have some white powdery residue on them so I wiped that off w/ my fingers and gave it a little air dusting and put the cover back on. To my delight I haven't had the problem reoccur. I did this on Tuesday and its almost a week w/ no red color loss.

I am an electrical engineer but that doesn't mean I know anything about TVs. I can read shematics and from the service manual (found on page 1 or 2 of this thread) I found the schematic of the video board and located the chip on the end of the TV tube. The chip is marked IC711 on the board connected to the tube just like the schematic on the service manual. If I'm not mistaken each chip has 8 pins so just make sure each chips solder points look good and if not then resolder or take to someone who'll resolder. If the points are good look for dirt or dust, clean it off and put the cover back on the back. All in all its costs nothing and takes about 15 minutes to do. The only problem is the thing is heavy and taking off your stand and putting it on the floor may take 2 people.

I saw a boxed RCA HD27F754T at Walmart this weekend for under $400.00 this weekend. It is a 27" 4:3 set. I did a little research and the only drawback I saw was the lack of an HDMI imput.

Hi all,

First of all, nice thread - those TVs are worth it. This post regards the 32" version. To sum up quite a few posts here: the red/green problem, right? How about a horizontal picture smearing? Jumping right next to the TV or kicking/banging it upside the head which corrects the problem (temporarily)? Clearly it's physical/mechanical and I'm not sure about the posted here "soldering problem". Anyone noticed that rocking the set back-and-forth a few times corrects the issues as well? Here is what I think - check the connectors between the boards (3 of them) - the white ones with several bent at 90 deg. steel-sheet "pins". Next, the ground cable to the CRT. I noticed those parts get physically stressed the most, and my TV started to give me problems after I moved out and in. So, after taking the cover off do the same as before - rock the set back-and-forth and see what gets stressed. I reconnected everything (almost... see the P.S.) and now it's fine. For those who can't fire it up at all or especially when the TV turns off after 1.5 or 3 s past "ON" - try the "SCREEN" focusing knob on the transformer - the TV has a safety "device" which turns the TV off if the voltage is too low and turning that knob (well, one way) basically does just that. BTW, I had to drill 2 holes in the back cover to have access to the 2 focusing knobs. Oh, remember that the voltage in the TV is way higher than sufficient to kill you :eek: , so be careful or don't "F" with it if you don't know what you're doing, especially when it's powered up (e.g. for focusing).
Overall, I think the problem here is the ****** back cover which is way too flexible and upon movement instead of damping the stress it transports it to the brain components. It seems like those are common trouble components. Additionally, anyone noticed that Mexico tried to save $ on the inside cables? Yeah, some of them are too short and cause the abovementioned problems on movement. The TV is still great. For the price that is. I've been running mine for 2.5 years now, HD programs for over 6 months (HD IS amazing...).

I hope this helps.

P.S. Can anyone with the diagrams help and let me know the exact location of the degaussing coil connector on the board (which board, symbol, etc.)? Forgot to mark that one before dissassembly. Yeah, stupid me and now no degaussing. Thanks in advance.

Hi everyone,

I bought the HT30744 at Walmart this past Friday in downtown Toronto, and it's great! It picks up several HD channels even though my apartment faces north and my view's blocked by a giant building.

Quick Q to the experts about the set--the Sanyo website says that scan velocity modulation (SVM) is a feature of this TV. That's probably why I'm seeing ghosting via the s-video input. There's no setting in the user menu to change scan velocity modulation--nothing even similar. I've checked the service menu and can't find anything with an SVM in the code. Has anyone been able to find a way to disable SVM?

Thanks for your expert info!

I have been buying component cables for my systems lately and my xbox looks beautiful on this tv, but my ps2 looks god awful. Its looks very pixalated and bad ghosting. Is this a problem many people have been having with the ps2?

I hav the 30746, and following various links in this thread, I have been able to fix most of my geometry problems. I only have one issue left to correct, the left side of the picture is about .25 in lower than the right side of the picture. So I need to rotate the screen a couple of degrees clockwise. Does anyone know if this can be corrected in the service menu, and if so, which setting do I change?

Thankss

No, it cannot - you have to physically move the picture tube.

Well, recently my TV developed some sort of high pitched whine seemingly related to either the deflection yoke or power supply. Sanyo wouldn't fix it a second time and replaced the set with an HT30746. New TV works ok, picture isn't quite as good but geometry is better. We'll see what happens.

Hi there,

I have the same TV; I believe there's the option to rotate the picture in the actual setup menus (not the service menus). I definitely remember rotating my picture.

This weekend my HT32744 developed a green picture. I bought this set from WalMart in Feb. of 2005. I immediately hit this thread looking for support. I read a recent post where the issue was "fixed" by physically rocking the set a little bit. I ran into the living room and tried it out. It worked! The image went back to normal.

I'm no electrical engineer, so soldering is definitely not an option for me. Hopefully my set's image problems were temporary and I won't have to keep abusing the set to keep it working.

Those of you that have experienced this 'green image' problem, is this something that repeats itself over time?


Thanks for the support and information on this thread. I really appreciate it.

Hate to be the bearer of bad news, but you definitely have not seen the last of the "greenies." If you go a little further back in this thread, you'll find quite a few people have suffered from it and the only person who got it to go away for good had a technician re-solder something on the red gun (the problem is actually the reds disappearing, which over-accentuates the greens).

Several people (including me) have used the defect as a way to badger Walmart into giving us exchanges for the new model of this set (conveniently forgetting exactly when we bought it, and claiming not to have a receipt). But that has been hit or miss, and that replacement model may not even be sold anymore.

Best bet is to contact Sanyo directly, make a big stink, and see what they recommend. Good luck.

I am starting to see wavy horizontal lines when playing my 360 hooked up through the component inputs on my 746. Are there any settings i can change to correct this so they are not as noticeable, or should i try and exchange the set at walmart?

Would a component to hdmi adapter help?

thanks

Would a component to hdmi adapter help?

thanks

Any component to HDMI adapter would be ridiculously expensive ($100+). Component signals are analog and HDMI signals are digital, so you're not taking something that just rearranges some pinouts. It would have to take the analog signal and digitize it, so it will take some computing power.

Yeah the one i saw was around $170. I think i may just stick with the t.v., until i can get another one.

Does anyone know for sure if you can receive qam channels w/ basic cable? The manual seems to suggest that you need digital cable. However I've heard here previously that you can get Qam clear channels via basic cable too. If I were to call TW and inquire about Qam would they know what I'm talking about? BTW I have the Sanyo 32" -HT32744.

Jimdoo,

It's going to vary by cable company. If they have a filter blocking all signals except for analog, then it will not work.

Ok, I am in a bit of a pickle here. Close to a year ago I purchased the HT30744 from Wal-Mart for $562. The TV has been great for that time, but about 3 months ago the HDMI port started to act up and the TV screen would go completely green (as in no other color except green--not the dreaded red failing stuff people have talked about). So I called Sanyo and told them what had happened. They said that I should bring it back to WM and get the TV that replaced the HT30744. I asked the person at Sanyo if the replacement TV was HD. The woman I talked to said no it is SD. Needless to was astonished and decided to use the component cable to view HD. I figured that while I could not get a picture with the HDMI input that I would get a HD picture with component cables.
Now this week the dreaded green people came to visit me and I do not mean the kids at Halloween. If I hit the left side of the TV I am able to get the red back, but that fix is not permanent by any means. Yesterday I called Sanyo and they said that I could take the TV back to WM and exchange the TV for the HT30746. My fear, after reading a lot of the posts from here (posts from January of this year til October), is that the picture is going to be crap when compared to the HT30744 (even with componet cables). I am thinking that maybe I could just try to get a gift card for the amount of the HT30746 ($478). And then just try to get some halfway decent HDTV that is LCD or Plasma. It is coming to that Black Friday time of year again.

Any thoughts and the picture quality. Thanks, Pete

Help, Our HT327444 needs help. Initially I thought I was only viewing shades of Green and light blue. This started about a month ago. We have had the set about a year.

I think we have two options: repair or replace.

I would like to make a simple adjustment. After reviewing the various forums and threads I see that the television and video world has passed me by. I think the picture tube still usees red, green and blue guns to develop the picture. However, as I read thru the different postings I can see that all else has changed.

Our symptoms seem to change as we change channels and Tv set inputs. The TV picture is derived from a DirectTV H20 receiver using an HDMI cable to connect them. In addition I connect a camcorder using S-video video and a Sylvania DVD with composite video. We do not have OTA where we live. We have a good B/W pix by adjusting color to "0" on the manual adjust.

I would like to repair it if I can make a register adjustment per the manual I donwloaded, but that manual is for the 30" set. .... has anyone used this manual info successfully??

Maybe I can adjust the drive/screen levels (....perhaps a register setting ) to correct our troubles?

Can I turn off each gun to see if any of the three guns have failed?

Last option is to give the set back to Walmart and go for the exchange. But I really like the set except for color troubles.

Thanks

After much thought and re-reading this thread, I called a strong friend and we dragged the monster TV out of its cabinet and attempted to repair the "greenie" trouble.

I resoldered IC 711 TWICE. NO LUCK! :(

Next I used my DVM to measure the DC voltages of the three video driver chips. They all had the same DC values on the corresponding pins so I feel the IC is soldered to the board. STILL NO LUCK!! :confused:

Still determined to fix the beast we removed and checked the cables & CB connectors for corrosion. I also removed the video board, checked and cleaned the two connectors on that board. No LUCK AGAIN!!! :mad:

( By the way, a previous entry discussed a white powder. I did notice white residue where the ICs were attached to the heat sinks. I believe it is a paste used to aid in heat dissipation)

The lack of red color is apparent on all sources I use; S video, composite or HDMI connections.

I am looking for the alignment procedure for this set so that I can make one last try since my tinkering may have the registers fouled up. Can someone guide me to the Idiots guide to setting up HDTV sets???

Next, I have the serial number so I can call Sanyo for any assistance.

Will provide followup.

Jimdoo,

It's going to vary by cable company. If they have a filter blocking all signals except for analog, then it will not work.

Well, it worked for me. I had to get Sanyo to send me the kit to enable Qam -but I am happy I did! Not bad channel selection either! I get 2,4,7, pbs and tbs + a host of music channels and cnbc world. Not bad for next to nothing! I use TW for internet and life line cable only and this is a great back up to regular ota progamming minus the break up's and drop outs I would normally experience with my ota antenna and minus Fox too- :(

Usually if you have cable internet, there will not be a filter on the digital stations. Good for you - glad it worked out!

I just want to echo the post below. My 32744 lost its red as well, and like others have described, it progressively gets worse.

So on the suggestions of this thread I called Sanyo Customer Service and calmly reported the problem. The tech was nice, took my info and promised that Mary Jo would call me soon. Yeah, sure...

Accustomed to most companies' service level, I expected to wait awhile or never hear from them again, but Mary Jo called later that same day. She let me know the replacement part was being sent to a shop near my location and that they would be providing the repair, including labor. There was never any discussion of warranty in either call, nor was I asked when the set was purchased.

My TV is now at the shop, but Sanyo's part thus far has been stellar service. I'm impressed with their willingness to take accountability for what seems to have been a production flaw. Most companies would deny, then deny again, then quote the warranty.

So, those of you with the green / loss of red problem, call Sanyo. No need to make a fuss or be "firm" in this case if you ask me.

Production quality aside, thumbs up for Sanyo.



I've been having the same "loss of red" problem (on my HT32744) that so many others have been reporting...we'll be watching as normal, and then the screen takes a blueish-green tint, as if all the reds have gone out.

I called the Sanyo service line, told them my problem, and ended up getting connected to a "Mary Jo." She was extremely helpful, and told me a "digital module" had gone bad. Even though I am WAAAY out of warranty (bought the TV in Jan '05, and it has an August 04 manufacture date), she offered to send the needed replacement part to a local repair shop and to pay for the needed work.

I'll let you all know how it goes. If you are having a problem, it couldn't hurt to call Mary Jo at 1-800-877-5036. Very nice, and very helpful.

I'll say this for Sanyo...their TVs are kind of cheaply made, but their customer service is better than most.

Does anyone know how to replace the system settings on the HT30746? I held down the volume button and replugged it back in to mess with the settings, but I changed a few with out writing them down and now I think I screwed up the ratio. Does anyone have the original settings or perhaps know a button combo to reset it?

Sorry master, the sets are individually calibrated at the factory - there is not a "default" setting.

What phone number did you call? I have a Sanyo DVD player with issues. I was on vacation a couple of weeks ago. I called periodically for four straight days trying the Walmart Sanyo support number. It was constantly busy until the third day. Once on that day someone picked up the phone but did not respond. It sounded like they just answered and put the phone down. I finally got to talk with someone on the fourth day. Apparently Sanyo doesn't update firmware on Walmart DVD players. Once they are out, that is it.

I called the regular Sanyo support number and they just referred me back to the "special" Walmart purchased support number. This worries me since I also have a Sanyo 27" HDTV and a Sanyo 32" SDTV from Walmart as well.

Hi there,

I have the same TV; I believe there's the option to rotate the picture in the actual setup menus (not the service menus). I definitely remember rotating my picture.


how do you get into the setup menu? :confused: this instruction book is poop. i really like this tv but the clipping on both sides annoys the hell outta me. :mad: anyone who can help i thank you in advance

Mine, bought in July 05, went green after about 8 months but healed itself. Then it went green again in June 06, so I didn't hesitate--I called Sanyo, who told me to take it back to Wal Mart.

They didn't have and couldn't find another, so they just gave me my money back.

Wow.

Based on that nice warranty experience, i went ahead and bought the Sanyo 32" LCD HDTV that they had at the time.

What are the best settings for color, contrast, brightness, etc. for the best possible picture?

My first hdtv just trying to figure somethings out.

Final post for OKGramps...After several calls to Walmart, the manager here authorized a swap, plus additional cash for a new TV. Took a little persistence but we now have a tv with red again!! Thank you Walmart and Sanyo!

So when you guys say the "digital module" is bad, are you talking about the digital tv tuner pci card in the back of the tv? I thought i saw another reference to this a couple pages back. How would this cause the reds to go out on all inputs? I put in a call to Sanyo today about my green problem, which came back worse than ever. I originally bought my tv about a year ago from Value City, so it only had a 90 day warranty, so it's way out of warranty. The CS representative took down my information and said he would pass it along to Mary Jo, but because they are so busy, I probably won't get a call back from her until after the long holiday weekend. We'll see how it goes.

My screen seems to be tilted a little to the right so if there is a straight line on the tv, it appears a little crooked. Is this something that is fixable in the service menu?

Hello all......I have a question to ask.......I have had a HT32744 for well over a year......Everything has been fine from the time that I got the set........Tonight my wife called and said that she could not get our channels 24-1, 24-2, and 24-3 (which have been there all the time that we have had the set.....There was no (NO SIGNAL) message the shows when the signal (OFF AIR) is low or down........I went to the menu and did a digital channel search, still no channel 24-1, 24-2, 24-3.......I did the search two times, and still no luck........Then I run up the channels to see if all of our other channels were still there......And guess what, there were all of the channel 24 -1 -2 -3 located on 49-1, 49-2, and 49-3......Now for the question........Is all that went on was that the television station changed there channel numbers ????.....BTW analog 24 is still channel 24.........No problem with the set ( I guess), but something that the station changed......The HT32744 set has been an excelent running television.......Thanks............dplugs39

I've had the HT32744 for almost 2 years and love it but last night I noticed after it had been on for about 20 minutes the picture became blurry with both the OTA digital and analog cable tuners. I had to go out for awhile so I forgot about it. when I got back and turned the tv on, the picture was fine but about 20 minutes later it went fuzzy again. I read through the last few pages and didn't notice anyone reporting this problem. Am I the only one? The experience with Sanyo customer support seems to be pretty good from the reports I've read, since this has been out of warranty for a year should I not waste my time with calling them?

That fuzzy problem is the exact reason why I'm here on the board...looking for answers. We, too, had the 32" Sanyo for about two years now. It's been working flawlessly, until we came home last night, turned it on and it was fuzzy. We turned it off for the night. This morning after turning it on, it wasn't just fuzzy, it was fuzzy and dark, with the colors all off (extremely red), and the entire screen was really dark. I could barely read the channel information. Does anyone has any suggestions? Is the picture tub shot? It's only been two years. This is terrible quality and reliability.

Hello all......I have a question to ask.......I have had a HT32744 for well over a year......Everything has been fine from the time that I got the set........Tonight my wife called and said that she could not get our channels 24-1, 24-2, and 24-3 (which have been there all the time that we have had the set.....There was no (NO SIGNAL) message the shows when the signal (OFF AIR) is low or down........I went to the menu and did a digital channel search, still no channel 24-1, 24-2, 24-3.......I did the search two times, and still no luck........Then I run up the channels to see if all of our other channels were still there......And guess what, there were all of the channel 24 -1 -2 -3 located on 49-1, 49-2, and 49-3......Now for the question........Is all that went on was that the television station changed there channel numbers ????.....BTW analog 24 is still channel 24.........No problem with the set ( I guess), but something that the station changed......The HT32744 set has been an excelent running television.......Thanks............dplugs39

It's not a problem with the set, it's a problem with the broadcast. In each broadcast, they usually put in the signal the channel that it should be "re-mapped" to. In this case, it's 24-1, 24-2, & 24-3. If that's not there, or it's not in a format that the Sanyo recognizes, the set will just show it on it's actual frequency 49-1, 49-2, & 49-3. You can send the station a little note and I bet they'll fix it pretty quickly.

That fuzzy problem is the exact reason why I'm here on the board...looking for answers. We, too, had the 32" Sanyo for about two years now. It's been working flawlessly, until we came home last night, turned it on and it was fuzzy. We turned it off for the night. This morning after turning it on, it wasn't just fuzzy, it was fuzzy and dark, with the colors all off (extremely red), and the entire screen was really dark. I could barely read the channel information. Does anyone has any suggestions? Is the picture tub shot? It's only been two years. This is terrible quality and reliability.

Sounds like we had the same problem on the same day. I didn't turn it on this morning but I have a feeling my problem will continue to get worse as well. :(

Well. Lets hope someone will come along with a fix for us. Take care.

So when you guys say the "digital module" is bad, are you talking about the digital tv tuner pci card in the back of the tv? I thought i saw another reference to this a couple pages back. How would this cause the reds to go out on all inputs? I put in a call to Sanyo today about my green problem, which came back worse than ever. I originally bought my tv about a year ago from Value City, so it only had a 90 day warranty, so it's way out of warranty. The CS representative took down my information and said he would pass it along to Mary Jo, but because they are so busy, I probably won't get a call back from her until after the long holiday weekend. We'll see how it goes.

Well, Mary Jo and Sanyo came through, and my tv is now in the repair shop getting fixed.

Well. Lets hope someone will come along with a fix for us. Take care.

It dawned on me this morning that I had used my AMEX card to purchase this tv so they should cover the warranty through Dec 23 of this year since I purchased it on that day in 2004. Thankfully I kept the receipt so hopefully they will take care of this for me. Looking at the warranty from Sanyo they agree to replace the set for up to a full year so I'm hoping AMEX will do the same or give me a full refund (doubtful).

I'm not impressed with Sanyo customer support. I called this morning to get a list of local repair shops of which they had two listed. The first number I called was for a rental place that in their automated phone system options did not have a listing for tv repair. After I waited for the operator for a few minutes I was sent to the voice mail system where I was told the voice mailbox was full and then I was disconnected. They will not be getting any of my business even if they do repair tvs. The second phone number was for a company located in a neighboring city about 30 minutes away. I called them but probably won't carry my tv there. While I was talking with Sanyo customer support rep I asked him about the problem I was having. He spent several minutes trying to convince me that the the problem was due to signal bleed between digital and analog and that all tvs would experience this problem. That was a load of crap and I told him so. The tv has worked well for almost 2 years and for it to suddenly become so blurry that it wasn't watchable is most definitely a problem with the set and not "signal bleeding". Anyway I filed a claim with Amex and they will pay to have it repaired, if it is repairable. If not they will reimburse me for the purchase amount of the tv.

Last update on this. Just got my tv back from the repair shop, and it appears to be fixed. Sanyo set up the repair, sent the part to them, and paid for labor. I couldn't ask for more since i'm out of warranty by 9 months. If you have the green tint problem, and you are out of warranty, give them a call anyway and they'll probably fix you up.

Well. Lets hope someone will come along with a fix for us. Take care.

I was just quoted around $400 to fix my problem. I'd almost rather have the money and buy a new tv.

FYI - after owning the HT30744 for almost two years I experienced the green hue issue for which turned into the no imagine whatsoever issue, Sanyo & Walmart exchanged the TV with no problem.

Hi All,
I hope this is the right place for this. I have been reading most of these posts, but haven't seen one to match my problem. :(
I have owned this Sayno HT32744 for a yr now. One thing that seems to be happening is that every so often my picture will brake-up into many pictures stretching from the top to the bottom but only about 5” wide. So it’s like having vertical venetion blinds with the same picture on all blinds. It last about a couple of seconds then goes away.
Could this come from interference?
Has anyone seen this before?
Thanks in advance

Hello all:),

I need help. I have had my set (ht32744) for a year. I purchased a ps3 and tried for the first time to connect via hdmi. The ps3 is currently setup via component. When I try to initialize the hdmi setting the screen goes black the hdmi in the top corner dissapears but nothing is on the screen or heard through audio. I tried all the ps3 settings. Hold the power button for 5sec. It detects an hdmi connection but when I tell it to connect via hdmi nothing happens. I then thought it must be the ps3.

I then took the system to a friends house that had a tv with hdmi and it picked up and played with no problems in hdmi. I have no Idea why his hdmi works and mine doesn't.

I tried different cables nothing worked. I am totally stumped.

I had a cable box that had dvi outputs I picked up a hdmi to dvi adapter. I turned on the box the picture came up then went away. I am totally fustrated and almost out of options. Any help would be appreciated. Does anyone have any problems with the hdmi on these sets.

IS it worth fixing. I called the sanyo support but get the vanilla treatment. Is there a setting I can adjust or check in service mode?

Thanks

My HDMI stopped working to my PC with my Sanyo, but both still worked with other devices. I eventually gave up on getting the two to play - the quality wasn't that impressive anyway.

So, without reading this HUGE thread, should I get the 30" WS SANYO???

If you can afford it, I'd buy a 32" LCD. The "generic" models are in the $500-$600 range nowadays, and will look better than the 30" Sanyo.

Thanks in advanceI see the 'vertical blind' effect on my HT27745 periodically, but only when my daughter plays her X-Box (connected via component, it has no HDMI). I'm now thinking it's in the set, opposed to the game console.

Purchased my HT32744 television 16 months ago from WalMart. The last week the screen turns green after a few minutes of operation. This TV has very few hours as my wife and I work all day and spend most of our nights out. It appears Sanyo has a big problem with this condition. I'm calling them in the morning to see what they plan to do. I will let you all know the out come as soon as I get answers.

After reading everyone's recent horror stories - I dug up my receipt and the three-year warranty that I purchased the following month just in case I need it in the near future.

Don't be too worried - the thread is full of horror stories now because this model is out of date and not for sale anymore. That means the only questions that will come in are from people having problems with the set. Mine is still running flawlessly :)

ditto that...there are a LOT of these TV's out there. The general vibe feels like Sanyo takes care of most people too regardless of warranty or reciept.

I'm not that worried - I was just making sure that I knew where my info was in case anything ever happened. It's been running great since March '05, and I will finally be playing w/ the HDMI input over the next couple of weeks.

I've owned my HT30744 for 2 years to the day as of Tuesday the 26th. The screen had started greening a good while ago however we pretty much grew adjusted to it. It wasn't until I received an Xbox 360 for Chistmas and hooked it up via component cables that green coloring become less of a nuisance and more of an outright impairment.

Having found this thread, the first thing I tried was tilting the TV on it's right side. Lo and behold the fixed the problem, not just temporarily but for the entire length of time the television was on from the point of the tilting. One tilt a day kept the green away until the TV was turned off again. Even with this new cure for the green, I had read many a post that mentioned that the problem was progressive and I decided to bite the bullet and call Sanyo, knowing full well what might happen thanks to many other user's accounts. Dave at Sanyo customer service proved incredibly helpful, and told me to take it back to any Wal-Mart and get the replacement HT30746 model, despite the fact that I was an entire year out of warranty and had no receipt.

Figuring that I'd rather take the new model and not push for a repair since I was so far out of warranty, I called the local Wal-Marts until I found one that had the unit in stock. This proved to be a trying enough event that it almost completely negated the positive experience I had with Sanyo. Regardless, we found a unit at a Wal-Mart a mere 6 miles away so I made arrangements to help move the behemoth of a television.

The Wal-Mart exchange process wasn't smooth by any means, but having been prepared to go in swinging, I was pleasantly surprised. The customer service employee was extremely patient and had no qualms with my story. I explained the situation and gave him the phone number for Sanyo which Dave had instructed me to do. They were able to get Dave on the phone after a brief wait and he was able to walk the CS employee through the transaction.
When all was said and done, the entire service desk experience probably took close to an hour as CS was usually waiting on hold for Sanyo, the electronics department, or a manager for the majority of the time.

As for the HT30746 itself, I can't say I'm entirely pleased with it. It's a little lighter than the HT30744, but it's still a monster. The new beveled speakers on the front are a little sleeker looking as well. The image quality however is a mixed bag. With the Xbox 360 over component, the image quality is on par with the HT30746, and the interference I had experienced previously is noticeably absent on the new model. The HD experience is definitely an improvement.

Digital cable over coax however is another story. The SD picture is just awful. Everything looks incredibly grainy, and small text is damn near impossible to read. The default picture settings for the TV are also terrible. Everything looks incredibly washed out and bright. I've done some tweaking, but if anyone has AVIA or DVE settings for the HT30746, I'd greatly appreciate them.

After all is said and done, I honestly wish I would have pushed for repairs to my HT30744, but being so far out of warranty, I didn't want to risk it. If any HT30744 users have the option of a Sanyo repair, or a cheap out of pocket, I'd highly suggest taking it versus trading in for the HT30746.

Has anyone been able to play the ps3 on the ht32744 model via HDMI? Or can someone test one. Just need to know if there is a problem with my hdmi.

Thanks

Yes,

I've been using the HDMI for the last 14 months. I do remember a couple of times that it wouldn't connect. It might have been the cable box or the TV. Typical turn things off and back on or unplug and replug. Nothing chronic or permanent.

This is directed more to RPerry, but other responses would be welcomed. My HT32744 is 16 months old. It started with a purple blob in the lower right quadrant about 6 weeks ago. Turning on/off would clear it up. Recently a blob (sometimes purple, sometimes red) has shown up at about 9 o'clock about 1/3 in front the side. I'm going to call Sanyo. What kind of responses has Sanyo been giving considering that there isn't an equivalent to the HT32744 anymore.

I must say Sanyo handled this issue very professionally. I called and was told they had a problem with the color modules on these tV's and all I had to do was bring it back to Walmart and instruct the Walmart customer service rep call Sanyo for approval and I would be issued a full credit including all taxes payed. I did this and received my full credit with no problem even the Walmart rep was surprised. Sanyo did such a great job taking care of this problem I purchased a new Sanyo 42" plasma tv the same day using my credit. My hat is off to Sanyo for such a standup operation.

We had similar except we had "greenie" problem. It took several calls to Sanyo and local Walmart store to get a good result. We eventually received full credit towards a replacement set. Our choice was a Sanyo 37"LCD.. Working great for the past few weeks.

Good luck. I hope you are as fortunate.

RPerry or OKGramps - Do you happen to remember the customer service rep that helped you? I just called Sanyo regarding having the same issue and was told that they are no longer allowing exchange at Wal Mart. Since both of you had success recently, I was hoping to contact the same CSR that you talked with.

I talked to a young lady at Sanyo Customer Service yesterday. I explained that my 16 month old HT32744 had blotches. She said that they were taking care of color issues irregardless of age and proceeded directly to a Walmart return. Her only comment was that I needed to handle the return between 7:30am and 7:00pm Central Time. That is when Sanyo Customer Service is open so Walmart can call them. So far so good.

I was surprised when Walmart and Sanyo allowed me to replace with a like item after the warrany went out. In my case Walmart did not have a TV service rep in the area. Since we have the maint. agreement, all was good. BTW the new Sanyo LCD is great! I did have to make several calls to both, so patient persistent may have been the key for us. I think the rep I talked with was Jim. Most of my calls were late morning, PST.

Good luck!

so it isnt just me? holy crap. looks like i wil be calling sanyo. thing is only happens when connected to external sources so i was thinking it was my dvi cable but it was happening on my svid as well so i thought maybe possible power and source signal overlap or what ever. anyway awesome. anyone have a # to call?

So when you guys say the "digital module" is bad, are you talking about the digital tv tuner pci card in the back of the tv? I thought i saw another reference to this a couple pages back. How would this cause the reds to go out on all inputs? I put in a call to Sanyo today about my green problem, which came back worse than ever.

We'll see how it goes.


Why would the Sanyo have only a 90 day warranty if purchased from Value City?
Why would the mfgr. warranty vary by vendor?

Value City models were refurbished.

The number for Sanyo is 1-800-877-5032


I called a few days ago after experiencing the green tint problem a few times over the course of a week. Since I bought my TV about 11 months ago I only had the problem maybe once every other month and turning the TV on and off a few times would fix it.

I have also experienced the "rolling interference" that some people have mentioned. Mine is in the form of red and blue dots flashing on and off across the screen and rolling down. They are about 4 inches long, they take up the entire width of the screen and they become more noticible during darker scenes.

After finding this forum and reading this thread I am going to exchange my TV before the problem becomes worse or my TV doesn't work at all.

If you have seen the green problem at all, my suggestion is get it fixed right away. It will gradually get worse and worse.

My HT30744 is nearly 2 years old.

Question for those of you who were recently able to exchange at WalMart by calling Sanyo: did you have to have the original sales receipt?

Thanks for the info....

I've got a almost 1 year old HT32744 and I've been getting the green color problem for awhile, but it wasn't very noticeable at first. I didn't have any component cables hooked to it for about 4 or 5 months. That's when I connected my original Xbox up via Psyclone component cables. It wasn't till Christmas when I got a Xbox 360 hooked to it via components that the color got really bad. It used to be on one side of the screen, but now it's showing up on both sides. Anyway, I've been planning on taking the TV back to Walmart before my 1 year warranty is up. I've got my receipt where I paid $577 + tax. Unfortunately I wanted to post here to find out a few things.

First, do you think I can return the TV back on a Sunday? Even though Sanyo is not open on Sunday? It's hard to take during the week since I work usually from 7am to 7pm.

Second, will I get cash back or will it be an exchange or will the money be put on a gift card? I'm seriously considering going to Best Buy if I get cash back since I'm not real impressed with what my local Walmart has in stock. I wasn't planning on spending more than full refund price and that means either getting a Sanyo 30" Widescreen Tube HDTV or going with a much smaller 26" LCD. I really got spoiled by the 32" 4:3 tube and going to a smaller TV is going to suck. I'd have to buy a 32" LCD just get anywhere close to what I originally had. I would have to go to a 40" widescreen LCD HDTV just to get the same size 4:3 picture on my 32" tube HDTV. Oh well.

Any suggestions for TVs at Walmart? I don't want to spend more than $675 if I go with a 32" widescreen LCD. What about Best Buy any suggestions for HDTVs(tube or LCD) that are $575 or less? What about 32" LCDs for $675 or less?

Thanks in advance.

When I talked to Sanyo Customer Service last week, they said that they were taking care of color issues irregardless of age and proceeded directly to a Walmart return. The only real requirement was that the return be made between 7:30am and 7:00pm Central Time. That is when Sanyo Customer Service is open so Walmart can call them. I had assumed that was Monday-Friday. It may also include Saturday, but I doubt Sunday.

We're not supposed to quote prices here, so I won't, but do yourself a favor and go to Sam's Club and Costco to check out the Vizio LCD's (32", 37", 46"). The 32" is in your price range and the 37" isn't much above it. Nobody every complains about getting a TV that's too big! I believe Circuit City carries the brand as well, but I never go there so I can't talk about their selection.

I have a Vizio 50" plasma TV and love it - more bang for the buck than any other TV out there!

I called my local Walmart today(Sunday mind you) to get the skinny on a return. They initially said they would only honor a 90-day return, but after I quoted my warranty in the manual and gave them the details about it being a special with just Sanyo TVs, they eventually agreed to let me return it. Since I had my receipt and it was less than a year, I don't think they needed to call Sanyo. Unfortunately they would only allow an exchange, so no cash and I'm not sure they will give me a gift card. With all that said they didn't have the TV I eventually decided on: 32" Sanyo DP32746. So I decided to wait till tomorrow and drive to another Walmart 30miles away that has my choice in stock. Sorry about asking for suggestions based on prices. Price is my primary concern, but also is warranty. The 1 year replacement warranty included with all Sanyo TVs at Walmart is definitely the clincher. If it had not been included with my TV I wouldn't been able to exchange it before it went completely out. So I'm definitely going to get another. Great job Sanyo and Walmart. ;)

AzBat

Hey, before you commit, if you can get a gift card, they ARE valid at Sam's Club. And Sam's Club has a no questions asked return policy - they might not take back a 5 year old TV, but they'd definitely take back a one year old one. Just do yourself a favor and go to one to check it out. Vizio also offers a 1 year IN HOME repair policy with all their sets!

Thanks for the info. I'm about to leave for home to pack it up and take it to Walmart. I'll see what they say about the gift card, but as I don't have a Sam's card not sure how I'd get in. :) I'll post here with my experiences.

AzBat

Well, I finally got my new DP32746, but it was no picnic. Hopefully posting my experience here will help any other guys that have the same issue.

Here's a couple of pointers to make sure your exchange goes well:

1. Make sure you have your original receipt. They'll try to scan it, many, many times.

2. Having the original box is a major plus. They'll try to scan that too.

3. Take your manual and remote! Says so in the manual! :) The manual's warranty will do wonders for convincing them they're wrong.

4. Call them ahead of time to get it approved. If you forget and you're already there, don't bring in the TV till you know they'll exchange it and they have your replacement.

5. Make sure you're there during Sanyo's business hours just in case everything doesn't go so well in the next item.

6. Tell them that all Sanyo TVs can be returned for an exchange after 90 days. They'll try to tell you they don't take TVs after 90 days. If they won't listen show them your warranty on page 30. They'll now can a manager to get it approved.
If the manager does not approve(because of out of warranty, etc,) then tell them to call the 800 number listed on page 30 of the manual.

7. Just because they finally approve the exchange, it ain't over. They'll have problems doing the exchange because the UPC number and the bar code on the receipt will not come up with a product or price. They'll need to verify the cost of your old TV. For me, they had a guy in Electronics go look it up. No matter the cost they come up with they should refund your purchase price. I'm not sure if they're suppose to refund the taxes, but for me they didn't and I forgot to ask.

8. They'll finally realize they no longer sell the same TV anymore. Be adamant that you are picking the TV of your choice and will pay the difference if it's higher.

9. Don't forget the 2-year extended warranty. It's not as nice as taking back to Walmart :rolleyes: , but you can still take it back there during the first year. After that, check your extended warranty plan for the number to call.

10. Don't forget batteries or cables before you leave. My Sanyo DP32746 didn't come with the necessary 2-AAA's. :(

My experience took just about 1.5 hours. Hopefully yours will be better. If there are any Walmart Electronics Dept. employees here, please for the love of God tell your Customer Service department that Sanyo TVs have a 1 year in-store replacement policy and to make sure they have some way of verifying the price if the product or receipt codes are no longer in the computer. Waiting 30-50 minutes for that was insane.

I'm getting really tired of this TV.

After getting it repaired because of the "green tint problem," where the red colors would suddenly dissapear (paid for out of warranty by Sanyo), the problem is once again back. Like before, a slight to moderate bang on the right side of the TV's cabinet will correct the problem for a time, though it will eventually pop up.

I haven't called Sanyo's customer service yet, and I'm not sure I want to keep trying to make this TV work.

It seemed like a great buy for $697 exactly two years ago this weekend. Digital tuners were almost non-exsistant in HDTV's at the time, and I appreciated being able to keep the 4:3 aspect ratio because the majority of programming is still transmitted that way.

However, the "green and blue blob" problem since day 1, combined with the "green tint problem" that has plagued the set in recent months, really makes it feel like a bad buy. One would think that a $700 investment would last longer. I'm not ready to be in the television market again yet....

...but I would like to watch the Super Bowl in correct colors!

I was looking at getting a ht30744 and was wondering if the new ones dont have these same problems. So if anyone can help me that would be great!

Obligatory: Back on Page 25... now I can really say "I told you so". Hey, that's 2 posts now (someone brutally called me a troll over my number of posts?) and to the (obvious sales) person who said that the 50,000 hour lifespan of Plasma TVs is an incredible 18 years of viewing time (because he feels nobody will watch more than 8 hours per day) --apparently he is unfamiliar with most multi-person households that run their TVs for 15-20 hours a day whether or not any specific person in the household is paying attention --especially when you're talking HDTV which runs 24x7 weather/traffic on some of the digital substations and you have a full house of people. Also, I am the last person to pull that funky sales math on --you see, I have a 36" Mitsubishi SVideo TV that I bought new in 1990 and run 15-20 hours a day and it is just now (in January 2007, some 17 years later) starting to exhibit the symptoms being described recently with this Sanyo model. Guess what my next model my next TV is going to be --hmm, they don't seem to sell it at Walmart because it is not going to be made in quality-challenged Chinese factories. To the guys who were in my face over how the geometry on their bigscreen was near-perfect after 'rolling the carton they came in end-over-end', I can tell you about the time that my immigrant boss took us all out to lunch in LA and accidentally got on the 405 using an offramp instead of an onramp --hey I'm here 20 years later and I'm calling you out on the carpet for being ignorant and liking it! And to the guy who thinks that these units were cheap because of reduced FEATURES as opposed to reduced QUALITY, such economics do not make sense for this kind of digital commodity (unless, of course, you consider QUALITY to be a FEATURE, in which case, he's attacking me over semantics.) Ok, I've had my 10 seconds of fun at this Sanyo roast. Two posts too many, going to be 3 in a second! :lol:

(/ducks)

(/ducks)

LOL. You make a lot of good points. Ultimately, this TV will make a good secondary set for the bedroom. The green tinting is only happening occasionally.

Time to upgrade! :cool:

OK, after having the "green tint" problem with an HT30744, it was replaced at Walmart with a HT30746. Hey, I didn't read up to realize the picture differences. But it's OK.

Now, my HT30746 just started something new. When I turn it on, I get this message:

"First
Please connect all signals and antennas to jacks and terminals on the back of the TV.
Then press the CHannel UP key."

Now, the TV has been working GREAT up to this point. I use 3 inputs, 2 using composite (satellite and DVD player) and 1 using component (PS2)

So, I press the channel up key, and it goes through a digital channel search. And then brings me back to a screen that tells me to check my connections and to run the channel search again. It apparently doesn't check for my composite or component connections. Nor does it look for any non-digital signals. (Not that I have any antenna to connect to it.)

I tried pressing the reset button (2x as directed by the manual) on the remote. Nothing. I tried unplugging the TV for a while. Nothing. I tried the "Tuner" button on the remote. Nothing.

Can anyone help me with this?

I set up a model similar to this at my local store. We were only hooking them up on component cables and weren't using the tuner at all. You have to scan through the channels two times. After the second channel scan, it should say something like no channels found. Then, the picture should go to static. Then, you should be able to select your inputs. It should only do this after you unplug the television. It shouldn't prompt you each time after you turn the television off to scan for channels.

D'oh! Thanks. Works fine now. Thought I had done that, but I guess it needed to be unplugged first. Man, I feel dumb... :)

I was just trying to test my digital cable channels again, and I can't get the "Digital cable search" to appear in the menu. I split the cable and plugged into both connectors, and analog cable works fine.

The only options I have are:

On analog tuner:
channel search
antenna selection
channel scan memory
initial channel

On digital tuner:
channel search
channel scan memory
initial channel

On the digital tuner, digital add-on search and antenna selection are grayed out, and when I do a channel search on the digital tuner, it only searches the digital antenna channels (while obviously not finding any).

Is there something else I'm supposed to do to get it set up for a digital cable signal? I know my first set worked with a few digital cable channels...

Later models had the QAM (digital cable) functionality disabled. You can call Sanyo for a firmware update, but it requires a PC to be connected to the television.

can i use the service manual or whatever it's called to fix the rotation on my screen? it's off by a few degrees, which translates to a very noticeable difference of over an inch between the left and right sides unless i crank up the overscan (which i'm not too enthused about)

oh, does anyone know the actual number of scan lines on the HT30746?

I am experiencing an intermittant problem with my HT32744.

Off and on when watching TV, I will get a high pitch squeal from the TV. Input mode does not seem to matter. I have tried viewing through my ReplayTV, and directly through the Ant inputs (Noise is audible in HD and SD channels).

TV is fed from local cable company, and HD is tuned through ClearQAM, not a cable box.

Any suggestions. If I turn the TV off, the noise stops immeadiatly, but will resume wehn turned on. It fades in and out over a 5 to 10 minute period it seems.

Hey - me too! I'm experiencing the same exact problem- mine is intermittent too. I called Sanyo and the woman said there were no other customers complaining of this. She simply recommended I check if the surround sound is set to on and to turn it off. I dont think that's really any solution! What if I want to use surround sound? I havent really tested it - but I believe it happens on multiple inputs on my set also- composite for tivo and normal ota via digital tuner. Well, if more people than just us two are having this problem I would be interested. Maybe sanyo will cover this issue as well even outside of warranty like the green screen problem.

talz13 you need to change the channel until it is on D03, the number may vary, digital cable search only appears in the menu when you have a digital cable channel selected, even if it is only the default one. Hope this helps, I had the same problem but quickly figured it out.

As far as the 30746's scan lines it appears to use the same picture tube as the 30744 which if I recall is a Samsung tube. Any differences in picture should be within the circuits that process the images. The set does look a lot better through HDMI than it does through component.

Technically a Samsung tube looks good in a Samsung set, so if this set isn't as sharp I think its due to the picture processing circuitry. All in all I've invested a grand total of $281 into this Sanyo 30 inch stuff, I've had a TV be it this one or the 30744 for over two years. The 30744 had to be repaired once for the greenies and would have been repaired again for other issues had Sanyo not decided to replace it. This 30746 so far has been OK and has better geometry. Not the greatest set but I didn't pay much either.

I use this set in the kitchen/dining room, it logs lots of use (there are days when it will be on all day being viewed by someone). If it holds out 5 years fine, most of the newer stuff should be way down in price by then. If it decides to last 10 years, unless I decide to go for something bigger, its probably sufficient for the kitchen/dining room.

Where the market stands now with what I've seen and given the time frame in which I purchased it, it may very well be the last new CRT set I purchase. I can't really use one bigger direct view anywhere. A year prior to this one I bought a 27 inch Samsung HD for an entertainment center which has a limited amount of space in it for a set. Since I've pretty much switched to HD sets everywhere where the main viewing occurs I'm curious to see how the last generations of the CRTs holds out against the LCDs I purchased over the long term.

I purchased my HT32744 from Value City in Nov 2005 and I love this set. For the better part of a year it worked great. It has a slight tilt to the picture, which I stopped noticing when I’m not looking for it and it has a little noise only noticeable in dark scenes, which I do notice sometimes when watching DVDs.

Over the last six months the “green tint problem” started. Like others it got more frequent over time until it would show up shortly after turning on the set. At first I was able the get rid of it by switching the set off and on. Lately that hasn’t been working all the time so I decided to take a look inside as I don’t have the option of a return.

Armed with the knowledge of the “resolder IC711 info” I looked over the CRT circuit board for bad solder joints. All three IC’s appeared to have very nice solder joints, as did most of the rest of the board. However, inductors L711 and L721 (red and green circuits respectively) both appeared to have questionable joints, where the solder was dimpled around the inductor leads. (I’ll attach pictures if I can.) I resoldered these joints. Just a quick touch with the iron and a spot of solder did the trick.

So far, so good. I ran the TV the rest of the day without the “green tint” showing up. I also watched for the noise problem in dark scenes and didn’t see it either. Whether it was the resoldering or just the disassembly/reassembly of the TV that fixed it, I don’t know. I’ll keep my fingers crossed and post again if the “green tint” reappears.

2 May 07: It's been 2 months and no green tint!

The 30746 is at Wal Mart for a great price. I am thinking about getting this for my kids to game and watch movies on, as well as watch some OTA HD. I have been reading this thread and the green tint issue scares me. Did Sanyo take care of that going to the 30746?

Value City has them on sale this week for less than Walmart. I bought one today but didn't notice any green tint.

Does anyone know where I could get the service manual for the HT30746? I've searched through this thread and found the one for the HT30744 and might be able to use it some but would rather have the correct manual.

I also googled it but didn't have any luck.

Thanks

Well, 2+ years and 2670 posts after starting this thread I'm back to see if anyone else is having color problems. I've sorted through the last few pages and apparently I'm not alone. I started getting the "green tint" problem in the last month or so. It tends to go in and out but it is there frequently. Has anyone had luck in the past couple weeks returning this set (32") to Wal_mart for an exchange or refund? I'd be satisfied for an exchange for something else they have in stock but I can't find my receipt so I'm guessing I'm SOL. Do I have any chance of getting Sanyo to help me out here? Anyone have a specific service rep they would suggest talking to?

This past week I have worked on getting a replacement on my HT30744 through SANYO and WALMART. My set was purchased back 4/14/05. I have been having the "green blob" issue since almost day one. Wasn't bad when it started and it happened very rarely. Then it just started getting worse and happened more frequently. At first, we thought it was the cable company, either our HD box or connection. So, we wasted over a year going back and forth with that. Here we are now, I did a search on the problem and found out we should of just returned, when we could, and purchase a different set.
This is what has taken place the last 7 days. From the previous threads I started by calling SANYO. They know about the problem and gave me a number to call HARVEY @ 1-800-877-5036. Sanyo is not instructing returns at Walmart anymore. They are finding you a local shop to take it to and sending out a replacement part. Now here is the bad part, you have to take it to the shop and wait to have it fixed and pick it up from the shop. Sanyo is not covering pick up or delivery. Wish I would of searched the forums earlier when they were exchanging set or allowing refunds. Just bought another set yesterday at FRY's Mitsubishi 52" LCD projection(WD-52531), with the matching stand(MB-52B)ONLY $999 - 5 yrs extended warranty(in home service) with 1 bulb replacement(mailed) $139. Brand new in the sealed boxes. TV stand is already assembled, in the box. Not buying another SANYO ever! They knew about this problem, I registered my TV with them, they could of send out a letter or email over a year ago informing us of the problem. This problem was a major defect not an isolated problem.
I even went as far by contacting about 12 local WALMARTS and speaking with the electronics dept manager. Not one had any idea what I was talking about. NONE had heard of any issues nor returns/exchanges. All told me that when they have major issues they get infromation from Corp. I live in the Chicago area, so I would think they sold a lot of these tv's around here. Where are all the returns and exchanges taking place!!! They don't even have the replacement model listed in previous threads.

I have a HT28745 - the 28 inch model - which I bought at Walmart at the end of last april. It died yesterday - it just won't turn on. I'm greatful this thing died on the 342nd day of a 365 day warranty. The warranty says they'll replace it with the same TV or a TV of equal value.

Obviously, they don't sell this 28 incher now, any idea what I can expect? Will they give me the next best Sanyo TV they have, or will they merely credit me the $380 I paid for this TV, toward the price of a new TV? I expect I'll just get the credit, but it doesn't seem quite fair to me because I can't buy any HDTV for $380. I suppose I'll be happy with whatever I get, but I'm just hoping somebody will chime in saying they had the same issue and they got an upgrade free of charge.

I just wanted to thank the posters on this forum for thoroughly convincing me NOT to purchase the 30" Sanyo HD set.

Was that supposed to be funny?
Listen, no TV is perfect. Whether or not the Sanyo's are less perfect than others remains to be seen. But this thread illustrates the benfits of the Walmart/Sanyo warranty.
Bottom line for me was that you won't find an HDTV with a QAM tuner for cheaper. And the ease of warranty. Given the choice, I'd never buy electronics at walmart. But given my situation, well lets just say this is the right pricepoint at this time.

Just an update on my situation - I called walmart and they said they'd swap my sanyo up to a year. I said, but you don't carry this anymore, so what will you do? They said we'll credit the price you paid toward another TV. I called sanyo and said, I can't get an equivent TV for the price I paid and they said well then you'll have to pay the difference? So I went into the store and had to wait for about a half hour because regardless of what the warranty said, the "computer" told them their was a 90 day policy on this TV. Finally, they said they'd do it for me "just this one time" and they credited me my purchase prive toward a new 30" widescreen HT30746.

So, I have an old HT30744 thats out of warranty. In attempting to correct the geometry, I killed it via the service menu. The unit powers up, but no picture.

My question is, has anyone successfully replaced IC802 (the EEPROM) and brought one of these units back to life? The part itself (Sanyo P/N 4093012803) is cheap, and I can handle the soldering - but I was curious as to whether or not anyone else had performed this operation successfully.

No, I'm totally serious. How can you say it has a great warranty? Read the posts.

Great thread, I exchanged my old HT30744 for the newer model HT30746 like a year ago. Recently I started receiving Vertical bars on the screen, this are only noticeable on dark scenes, I have my dvd player hooked via component, a dish HD box, on component 1 and my gamecube on component 2, I get the interference bars on all three imputs. I read that some folks had this issue, did anybody find a way to fix it?

Thanks!

I have a HT32744 that I got in August of 2004. A couple months ago, I noticed it started losing all red from the picture intermittently. Then, a couple weeks ago, the screen started going all dark and smeary. It works correctly most of the time, but has this problem off and on. While it's well out of warranty, I'd expect a $750 TV to make it at least three years. I've contacted Sanyo and been instructed to call them. Lets see how it goes.

I was told to bring it to a repair shop and they'll fix it if it isn't the tube.

I figured I would give my general impression of the TV as long as I'm reading the thread: good value for the price. Way too heavy for someone who lives in a 3rd-floor apartment. There are several picture problems, most notably barrel roll there I could hide most of it with a bit of overscan, but I have some in the upper right I can't get rid of without having way more overscan than I want, a red push I managed to make better, but not get anywhere near eliminating, the picture is rotated 3 or 4 degrees counterclockwise and the colors are noticably redder in the lower right than the rest of the picture. 720p is soft on the right side. It's not normally noticeable, but it is when I play a game with text. It has a problem where the pixels won't hold still, but this goes away after 10 minutes or so of operation.

If anyone is interested, around here the Wal-Marts have the HT30746 down to $398 on rollback. They also have a new SDTV model also 30 inch widescreen which if I recall correctly is $347. To me, despite the flaws, the 30746 is a steal at $398 for what if offers. Makes a great set for secondary use in a smaller room.

This Sanyo HT30746 and its SD counterpart are at least for now being stocked side by side but the 30746 is the only HD tube I've seen at Wal-Mart since last year when they had some RCAs around Christmas.

I honestly don't care either way, some people prefer tubes. Some prefer flat panel. Some prefer rear projection. I've got all types, I don't care as long as the technology works.

My main point is $398 for a 30 inch widescreen HDTV is cheap for what it is. Granted the HT30746 is not the best HDTV I've seen, and the only reason I own one is because I got the HT30744 for for $281, and they replaced it with this after the original developed more problems after the green tint problem was repaired. You'd still spend quite a bit more to get a similarly sized flat panel, and the cheapest ones don't generally have the best black levels. I use this set in the Kitchen, it is on a stand in a corner where a flat panel would not save much space so for the purpose it works great.

Here's a picture of my TV. You can see the color problems and the barrel roll in the upper right. It only gets like this after running a few hours. So far, I've been unable to catch it with the green tint problem or the smeary thing. This is what it's always done.

For those of you that had repairs, did it fix this color problem?

For those of you who have not yet taken up the offer,from Sanyo, of getting the tv fixed by taking it to a tv repair shop. Yes, Sanyo does pay, but you need to take it and pick it up yourself.
Mine is done at the shop....beware, the only thing Sanyo has them do is to clean the boards inside, nothing else. I will follow up once I pick tv up and watch it for awhile.

According to the shop that's going to do mine, they replace the digital module.

I should of stated that the only problem that I was having ,so far, was the "green blob" problem. Hopefully, that will fix it, but I am not going to hold my breath. Seems like people who have it fixed continue having issues of some kind.

Is there any way to get the digital module without having to take the TV to a shop? I would even consider buying it. With my TV the green tint is a once in a blue moon thing and moving it would be a major operation since I don't even own a car.

I have a ht32744 also and like ACE I have the same video problem: blurry image and intense colors. I bought it 92/05 so had a repair man come out and he immediately determinded it was the the comb filter, is this the same as the the before mentioned digital module? I to think that a a $700 tv ought to last more than 3 years as does ACE. ACE, who'd you call at Sanyo? We called customer service Saturday 5/26 and was told to call a man named Harvey Tuesday the 29 after Memorial Day. Question ACE: Is this who you called and when you did get hold of someone how did you describle your problem? You said they'd stand behind the repairs except if it was th tube correct? This repair shop wants $360 to fix the tv which is better than buying a new one that is not as good s set as this one is.Please let me know how you handle this even if you want to e-mail me I'd appreciate it. Thanks guys for all the info about this tv I do feel it's worth fixing in lieu of replacing it. If anyone will help me prepare to talk to this Harvey guy Tuesday I'd appreciate it.

I hope this can clarify questions for some of you.

As far as I can tell (from my experience) a replacement of the "digital module" will fix a green tint problem...that is, if you lose your red color, causing the entire screen to take on a greenish appearance.

The green blob is a seperate issue. There, when you have high instances of bright white on the screen, a very distracting green blob will form on the right side of the screen, and a blue blob will form on the left. A Sanyo rep told me on the phone back in 2005 that this was a defect of the TV...not repairable.

You can make the green blob problem go away by notching the brightness way down on the TV. I've all but eliminated it that way.

EDIT: Ace, a digital module replacement will NOT solve your problem. It is the defect of the TV that I mentioned above.

I'm back, can't wait till tomorrow so I can call the number that Sanyo CS gave me to call. After reading most of the posts about this tv I feel that Sanyo will treat me fairly which is all one can expect these days. There seems to be more negatives about the ht32744 than pluses but I agree with the few positives that this is a good tv. I had a repair shop take this unit back to their shop for repair Friday and the tech that came was a grey haired gent who said he'd been working on tv's for 25 years and he took one look at the tv, fortunately it's problem was at it's peak and he said it was definitely a problem with the "comb filter". I still don't know if this filter is aka: the digital module. Sure hope this tech was correct and that Sanyo cs helps fray the cost of the repair. The wife is adamant about getting this set repaired hopefully under warranty. It's 2 1/2 yrs old, it's problem is the exact same one that Ace's picture displayed earlier, intermittently blurry. I looked at some Polaroid LCD's at Wally world yesterday that had max res of 1368x720p and it sure looked good! But dw says "absolutely NO", I'm sure the rest of you guys don't have such problems with your dw but I do. Oh well, wish me luck tomorrow.

My 32" had the green tint problem pretty bad (my tv stays on 24/7). I had called Sanyo a couple months ago and they told me where to take it. 3 weeks ago or so the tv would not turn on and I had not taken it yet. Called sanyo again and they said to take it now. Have not heard yet as the repair place was pretty busy.

I made contact with cust. eervice and told them that my set was in a shop and quoted the estimate I'd received. I was told that was too much and that he'd call and talk to the shop. He did and told them to clean the contacts of the digital module (aka: comb filter). This will bring the repair cost way down. Today I returned cs call and ask if this didn't correct the problem do I have any recourse? The rep said that if it didn't to call him back and he'd make it good. This sounds fair enough, I am out of warranty but goodness the tv ought to last more than 21/2 years. We'll see, glad I found this forum.

I've lost 2 previour posts, how tiring!
Quick summary of our problem:
Our repair shop replaced video filter aka: digital module or 3d digital filer whatever you want to call it.
The TV works just like it should now and looks great.
Repairs were pricey according to Sanyou customer service but hey, it works now Sanyo. Sanyo didn't have to frustrate me and upset my wife but they did.
Now we have a total of $1000 in the tv that's not quite 2 1/2 yrs old. We thought Sanyo should help us but they didn't see that way!
Oh well lesson learned, but Walmart will hear from us about how a vendor of theirs treated us. Won't help us I'm sure Walmart would like to know this.
To you with video problems; don't rule out the digital moduel, it could be the culprit regardless what Sanyo says.

Why would you spend that much repairing this TV when you can get a 32" - 37" LCD TV for $500-$700? If my TV breaks, I'm replacing with with something nicer and more energy efficient.

I think he saying he spent $350.00 for repair and paid 650.00 for the TV, so he has a grand into it.
I hope he didn't spend a thousand dollars to get it fixed. :eek:

mrpergo is correct, $650 + $350 repairs. Costly, yes, but still cheaper than adding 7 to 8 hundered more to buy antother set. The repair bill took us aback also but I've made costlier mistakes in my lifetime and ended up with nothing to show for it. At least this time I have a tv that works. Starting day 4 and set is performing perfect so I'll just lick my wounds and go on.

I just wanted to thank the posters on this forum for thoroughly convincing me NOT to purchase the 30" Sanyo HD set.
In that case, I'm glad I didn't run across this thread when I purchased a refurb 30" from Value City for $299 in August of '05. It's been a workhorse in my narrow family room since then and will move it to bedroom(with help :p ) as we upgrade at the end of this month. I've had nothing but joy from this set and consider it the best TV purchase I have ever made.

Also, can anyone direct me to the Service Manual for the HT30744?

Thanks

Got my tv back from the repair shop SANYO sent me to. Had to pick it up, of course.
I saw the bill to SANYO, it was only $75.00. All they had him do was clean off the contacts on the boards. The shop said they ran it for 2 days with NO problems. You must be kidding me, 3 months of going back and forth with SANYO, hauling the TV back and forth to the repair shop for this. I could of done the cleaning myself! That's why Harvey (from SANYO) would not say what the problems are with the TVs. I think if cleaning was all these tvs needed, they would not of had people returning them early on. Well, I will give an update once we run the tv for awhile.

I am glad to hear that I am not the only skeptic. Harvey did call,and that was confirmed by, the repair shop. He told them to clean the contacts also, of course the repair shop wasn't working for Sanyo and replaced the module as they had diagnosed to start with. At least I have a 120 day warranty on everything done by the repair shop which I'm sure I wouldn't have gotten if they'd followed Sanyo's instructions. I am with you, if the problem was so simple why did so many others have to return their sets? I figure that by replacing the module I got a new module as well as clean contacts as a result. But the tv is working fine and I am happy with its display, it looks good on analog as well as digital signal. But ol' Harvey cost Sanyo a future customer for sure! All in all I like this tv.

Is this Digital Module a part that can be unplugged from the TV chassis by the consumer and then the clean the contacts himself? I had one I sold to a friend and if she starts having problems with it that info. would be nice to have.

Is this Digital Module a part that can be unplugged from the TV chassis by the consumer and then the clean the contacts himself?Only if one knew what they were doing, such as an experienced service technician. One wrong move and---BZZZT! :eek:

The basic safety precautions are to:

1. turn off the tv

2. discharge the picture tube

Once you have done that the tv is safe to work on

Having said that you should be comfortable working with electronics before you go around screwing with the inside of a TV set

Also, can anyone direct me to the Service Manual for the HT30744?

Thanks. That stuff looks a little scary.

I have a Sanyo HT28745 that I purchased reconditioned from a Atlanta retailer back in December. I initially had one issue with the unit when I brought it home, but I was able to fix it relatively easily, and since then I have been very happy with the product overall. (In case you are wondering about the issue I had initially; the left speaker that is built into the TV had generated an annoying vibrating sound. I was able to use a paper clip to remove a piece of plastic, left over form the manufacturing process, to eliminate the offending noise.) Yesterday I turned on my TV and I was horrified to see a very nasty purple ring around the image that would not go away. I quickly started doing searches online for possible solutions since my unit no longer carries a warranty. During the course of my searches I found this forum. I was never able to find a solution to my problem online, but through some analysis of my unit, I was able to fix the solution on my own fairly easily. I wanted to post my solution on here so that it might help others with similar problems.

For me the fix was fairly simple, the degaussing coils had come loose from their posts, and so all it took for me to fix the issue was to take the back of the TV off, look around for the degaussing coils (they are very easy to find since they are triangular wires attached directly to the tube body), and reattach the wayward power wires. The wires themselves are connected to the TV control board by plastic encased leads, and they connect at the front of the TV on the side where the AV plugs are attached; right next to a relay. There is nothing but friction holding the connector in place, so I think that the connectors slowly separate from the pins from heat creep. This process may also be helped along by inadvertent bumps during the moving/setup process. I am not sure if the design is exactly the same on the HT32744/HT30744, but given how much I have seen companies scale/recycle proven designs, I would not be surprised if it is exactly the same.

Got my tv back from the repair shop SANYO sent me to. Had to pick it up, of course.

How did you get Sanyo to send you to a shop? I'm on my second Sanyo 42-inch plasma that's gone bad. The only response I could get from Harvey was "nothing we can do" and that I could take it back to Wal-Mart, but the new one would "probably have the same tendencies."

My understanding is the only post warranty work being authorized by Sanyo is the "green tint" problem (which is actually a loss of the red gun) on the HT32744. The reason they are fixing this problem after the warranty has run out is because it is a mass manufacturing defect in a significant number of HT32744 TV's.

I believe this has been touched on previously in this thread however searching almost a hundred forum pages isn't something I care to do.

The basic safety precautions are to:

1. turn off the tv

2. discharge the picture tube

Once you have done that the tv is safe to work on

Having said that you should be comfortable working with electronics before you go around screwing with the inside of a TV setIt would also help to unplug it first. This procedure is not for the faint of heart, or the inexperienced.

Sorry to have repeated info. I just stumbled across the post, and was just searching for any alternative to haggling with Wal-Mart (which seems to have a difference of opinion with Sanyo on how long the warranty is) again.

It would also help to unplug it first.
:eek:
Good one!

So the Green blobing is not prevalent on the 30s? Sweet

Please, anyone answer this question to the point.. WHY WONT MY HT30746 32 INCH HDTV 1080I ONLY FILL THE SCREEN ON PIX SHAPE 1 (PIX SHAPE 2 CUTS OFF THE LEFT AND RIGHT OF THE SCREEN A FEW INCHES) AND FILL THE SCREEN 16X9 AND NOT WITH BLACK BARS ON THE RIGHT AND LEFT? I DONT GET IT! XBOX 360 1080I COMPONENT AND THE TV 1080I, BUT NO FULL SCREEN? WHY?

Well after almost 3 years of owning the 32 inch I started to have issues this week. the screen will get blurry for a few seconds up to an hour. I've tried turning it off and on and it has not helped. I don't think I'll bother calling up Sanyo because It has been almost 3 years since the purchase. Any input????

I'm sure during the next few weeks I'll start my search for a new tv .....

First...

STOP WITH THE ALL CAPS!

It is considered yelling, and is *QUITE* rude.


Next...

Bad news, your TV is a 30", NOT a 32"!!!


Finally...

Check the settings on your xBox and make sure that the TV type is set to 16:9, not 4:3. (if such a setting exists on the xBox?, I don't have one myself)

Here is detailed information on the issue I'm having with my 30 inch Sanyo Vizon HT30746 HDTV... I sent this email to sanyo tech support as well, to a guy named harry, because Jim was out today.. Hopefull between them and you, someone will simply give me a CONCRETE answer! :)

Here is what i've come up with so far. Keep
in mind, I have read over 100 posts concerning this TV, but haven't received a
concrete YES/NO answer on it.. Honestly, I don't think it's a defective TV, it's
just the way the TV handles HD singals.

XBOX360-- Hooked up component (tried both inputs to verify, same result).. XBOX
is SET to 1080i (Tried 720P, same result) widescreen mode (Only choice you have
when you set it to 1080i or 720p).. I've verified this several times, and also
checked on forums concerning xbox, it's hooked up correctly. The screen (in
pixshape 1) with the xbox gives me black bars on the left and right, 4:3 aspect
ratio. Yes, the picture is much better than composite (i tested that to see),
but I can't get a full HD 16x9 picture on a 1080i input unless I switch to pix
shape2, which stretches the image, cuts off parts of the image on the left and
right.. Also, looks crappy (cause it's just a zoom)... I am at a loss,
quadruple checked all settings, over and over, same result. Everyone on xbox forums can't understand
why it wont work. Also, I tested this xbox on my parents HD dlp tv, and worked
perfect and automatically was full and not cropped 16xx9.

TIVO-HD DVR-- When watching HD channels such as HBO HD, ESPN HD, etc.. The same
thing as on the xbox.. No 16x9 without the zoom/pix shape 2... Once again, nice
picture, but 4:3 on the tv... I tried every setting on this box, over and over
and over and over, same result. On my parents tv, once again, this tivo hd
worked perfect in 16x9....

Lastly, I see on pix shape 1, on sattelite and some games, an overscan line to
the left edge of where the pic cuts off, about a 1/2 inch from it.. A solid
line, sometimes green, mostly dark gray. Shows up mainly on bright screens, and
I've turned the brightness way down, it helps. I know there are options in
service menu, but I have no idea how to access it, and I don't want to make
things worse. Also, no wal marts in my area have this TV anymore, so exchanging it would be hard.

I hope all this helps. The one thing I haven't tested is THE HDMI input. I
don't know if that would change anything concerning the hd feed, as the xbox
doesnt have hdmi, and I wont be setting up the HD TIVO for about another 3 weeks
(My parents are finishing watching al the taped shows, they upgraded to
directv's own hd dvr)....

That should help.. Keep mind I've checked everything on my own that I could,
read hundreds of post on avs forum and such, and I'm stumped at this point!

Thanks

HI Folks,

Wondering if someone might have a tip on how to cure a problem I am having. I am getting Dark smears (very dark on the left spreading to lighter on the right) across my screen.

It just started happening a few days ago. At first it would go away after the TV had been on a few minutes, but now it seems to be permanent.

Any thoughts on that would be greatly appreciated.

Tv model do you have? Also, the # for Sanyo I'd recommend calling is 800-877-5036, ask for Mr. Jim x 1712, he is in cust service, but knows these tv''s well.. Also, I have the service manual for the 30 INCH HDTV Vizon CRT model if you need it.. HT30746

It is te HT30744.

I have the service manual, but unfortunately I don't know whats causing the problem (so I have no idea what the solution is)

Any one have thoughts?

Hi guys. First time poster, long time lurker.

I have a geometry issue with my HT30746 30" wide HDTV. On letterboxed content, the upper right hand corner of the picture is quite a bit lower than the left. However, the bottom line is OK. Furthermore, there's some weird "overscan" - a bright line on the left side of the screen.

Sanyo says I have to return the TV. They said it's an unadjustable issue with the tube itself. It doesn't fit too well into a Ford Thunderbird. I found a link to the service manual once before, and if I'm going to return it, I know Wally-World won't plug it in check it, so maybe mucking around with the service menu might do some good.

As an aside, the recordings are great on their hold music. As a Pennsylvanian, the only time I hear a southern accent is when someone's talking about the last deer they killed, not how to properly hook up a progressive-scan DVD player.

EDIT: Ack! I found the service manual. However, for pincushion adjustments, there's only an Upper Level and Lower Level pin adjustment, not one for each corner. I'm pretty sure it can't be the phase or angle, since only one corner is off.

EDIT II: Okay, I'm done screwing with it for a while. I have a service manual for a HT30744, and the numbers in the service menu it refers to are certainly not the same.

Beachneedle,
Have you tested the HT30746 with a HDMI cable yet? I'm thinking about purchasing this unit, but I also noticed the same zoomed problem with the display model vs other 16:9 LCD's & Plasma's @ Wal-Mart?? Anyone out there who owns this unit, can you help answer this question?
Thanks!!

I haven't.. My 360 is component, and I haven't hooked up my hdmi tivo just yet, soon.. I'm guessing it will be the same, but may have a more fluid picture...
