I've been using a 30746 in the dining room via an older Scientific Atlanta DVR HD box which has a DVI out in the back. I use DVI to HDMI converter, set the box to pass through / 16:9 and the box sends whatever the HD stations are in their broadcast resolution, the TV resizes them automatically, never had to touch anything on the TV to do this just sits on pic shape 1. If a 4:3 is broadcast it is automatically pillarboxed, and if HD content is received the picture then fills the whole screen. I believe the key here is to allow the set to resize as opposed to trying to force it to a particular resolution. I think if you try to force feed it a specific scaled resolution through the HDMI it will do as described. As far as component when I used that I remember having to resize the image as it would stretch 4:3 content but never had much of an issue beyond that.

My 30746 has better geometry than the 30744, when displaying 4:3 there is less bowing to the picture (almost to the point of being unnoticable, something I'd never even attempt to adjust, as far as picture tubes go it is pretty darn good). I've never had much of an overscan issue, it does scan wider than a fixed pixel display, I can tell that by lining up the ABC HD logo to the side on both types of sets for comparison. The amount is insufficient enough that it makes no difference in viewing and is within the realm of what I've seen with most CRTs. Usually some amount of overscan is built into to compensate for voltage differences in the line.

Interesting, because when I have an HD feed, it does not fill the screen, it puts it in a 4:3 ratio, although the picture itself is very nice, HD quality. I wonder why component won't work correctly? Now, if I go HDMI TO HDMI, I wonder if it will do the same?

Not to sure why it wouldn't fill the screen, however at least one of the modes should when displaying a 1080i signal, perhaps they changed what picture shape corresponded to what setting I'm not sure, and I know that you can change these all around in the service menu.

Regardless of what setting is what, if its working properly with whatever picture shape you're using when you flip to a 4:3 source you should have black bars on the sides, if not you're stretching the image. When it goes to a 16:9 it should then fill the screen. If you feed the display a fixed signal, such as a 4:3 480i/p that is upconverted externally to 1080i the TV will usually stretch it to fill the screen as it seems to think that this is an HD feed. A true 1080i signal however is just that and the TV will display this as it is. Hence if you don't upconvert the signal to 1080i from the 4:3 source it should have black bars and look like a normal non widescreen set would.

It did take some playing around with the cable box to make it work right, generally the best solution was to pass through whatever the existing resolution the stations were using, then it just automatically adjusts the aspect ratio accordingly. Hence 4:3 will have black bars, whether 480i or p. 1080i, 720p will automatically fill the screen, I have not had to change the picture shape since this, the TV automatically resizes based on the incoming signa;.

Now if they changed how the picture shape settings work I'm not sure, but to test if you're using the right one find a stationary pattern (such as a logo in a screen corner) and test the picture zoom settings, the proper setting for the 16:9 should not adjust the vertical height, only the width. The TV will overscan between a half an inch and an inch on the sides depending on the incoming line voltage. This probably can be altered in the service menu. The important thing to watch for is whether or not its zooming vertically, if it is then you're not using the right setting, hence the station logo should appear at the normal height for it (probably best to check with another TV to see where the logo should be positioned height wise). 4:3 sources should have black bars on the side as a 4:3 would, if not you're stretching the image, or providing an upconverted image the TV thinks is HD and thus tries to display as 16:9.

Depending on sources being used how it works might be different. This TV is not alone in its anomolies with picture settings. My Sony 42A10 responds differently to signals/resolutions. Hence when using 480i on an old DVD player before upgrading to HD DVD, you had to set the DVD player to 16:9 widescreen, the TV would display it as 4:3, and you actually had to set it to zoom for it to be the proper aspect ratio. Why it worked that way is anyones guess. LD over composite yielded even more oddities and required its own settings (zoom1). Cable box had to be set to Full to get the proper image sizing.

My flat panel here in the bedroom almost always has to be left on Full to get the proper image sizing.

I think a lot merely has to do with how the TV responds to the various input resolutions. Manufacturers probably do as they see fit.

Rocking the TV gently did the trick! Thanks all for the suggestion.

Hi, I got a HT28745 from my parents who got a new TV.. Have had it for about a week. Well, I got some component cables for my DVD player and plugged them in. Well where I had the audio cables plugged in ran through component 3, so I was going to switch the component cables to there.... and then the TV clicked off.

So, now the TV won't turn back on. It clicks on and then a couple seconds later clicks back off (no change to screen). Does this three times and then it won't do anything unless I unplug/replug it in.

TV is out of warranty.... HELP?

I have the 30744 and its service manual. Which adjustments would I make to adjust the convergence? (I imagine the adjustments would be green-red and green-blue, with horizontal and vertical for each? not sure) The service manual doesn't elaborate on the meaning of each item, so does anyone know?

I just finished cleaning the contacts on the digital module (ATSC tuner) in my HT32744. Took about an hour from start to finish. Definitely not for beginners, but an experienced electronics hobbyist shouldn't have any problem. Only difficult part was releasing the 3 retaining clips (one on each connector) that lock the module down, because you can't easily see or access them. A chopstick was the perfect tool for that job.

I did a two-step cleaning process using DeoxIT cleaner followed by DeoxIT Gold (formerly ProGold) to prevent any future oxidation. The results are immediately obvious: reds are now MUCH brighter and more saturated than before. Even more than when the tv was new. I'm hopeful this is a long term fix for the green tint problem (loss of red).

My short term fix for the green tint problem was to thump the back of the TV where the connectors are (close to the HDMI connector). It always worked, but was getting annoying (once a day or more).

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.

I'm having the same problem.
Sometimes, but not always, when you turn it off and back on it will clear up.
I have also tapped pretty firmly on the frame just above the screen and got it to clear up sometimes.
If none of this works try gently rocking it back and forth. This always clears it up for me, but I'm afraid its going to break the shelf on my cabinet.
Mine also will just get blurry at times and loses audio.
I'm abouth ready to junk it.:confused:

I purchased my Sanyo 30744 1/05 at Walmart and had a problem right out of the box called Walmart and they replaced TV with another... no problem
The 2nd TV was excellent with DirecTv (component) but when I switch to cable the HDMI would not show a signal...Called Sanyo (Harvey) and he arranged a home service call to replaced the HDMI component ... didn't solve the problem..and after much research I was told that since HDMI was so new that there was no standardization yet and my Sanyo was not compatible with the Scientific Atlanta HD box so I used component cables..
About a week later a Sanyo manager called as a follow up to see if the problem was resolved.
I've had the Green Issue for sometime and thru this Forum and thread I have been fixing by slapping the top of the TV.....dirty but quick
Two weeks ago the TV started to blink....picture / blank / picture / blank etcand the Green Issue was happening frequently.... slapping wasn't working.
Being that the TV was 32 months old and way out of warranty I called several local repair shops and got ballpark estimates of $500+ if they could get the parts.

I started looking at new LCD TVs.

Then I thought as a last resort I would call Sanyo and ask if the Green Issue and the Blinking were known to them?....was there a fix?....and to my surprise they said that they would cover the Green Issue under warranty because it was a knownproblem...they located a repair shop close to me and I schlepped the 135lb Monster over to them.
Just got the TV back and fixing the Green Issue fixed the Blinking problem.

I want to commend Sanyo for their handling of this problem and they have a customer
for life....Sanyo will be the first TV I look at for my next purchase.

Is there a way to browse the menu without a remote? I bought my TV about 5 months ago from a display model at Wal-Mart and I have a universal remote, but it won't allow me to go up and down through the menu. It changes channels and all that, but can't do anything else with it. I don't really want to spend $35 on the exact remote, but I might have to.

I can get the menu screen to appear.. but can't navigate.

Hdizzy, that's good to hear.
I just started getting the, "green screen" myself, after purchasing the TV in April? of 06. I'll give sanyo CS a call and see what they say!

Ok. I got the official controller. My question now is this:
If I am having a hard time getting the channel search to pick up a channel (digital), how can I manually add that channel? Like when I search, sometimes it will pick up a channel and not pick up another one, so I redo it to get the other one and then the channel that did show up doesn't show up anymore.

Can I not just pick a channel and add it? Its kind of annoying.

I always had/have to do the "add on search". It's better than most as the TV won't wipe out your previous found channels. I wish my new LCD would do this, it doesn't retain the old channels like this set does.

Just an odd observation, for some unusual reason the HT30746 looks surprisingly much better with football games than it does with most other HD programming. Or at least better than I've ever seen this set look since I got it. I never thought this TV was as good in picture as the 30744 aside from the fact that the geometry is much better, with almost perfect pillarboxing on 4:3 content (virtually no bowing). I wonder if the cable didn't just start to constrict bandwidth as they added more channels, which would account for looking worse than the 30744. They started to add channels right around the time Sanyo replaced the other one. I never really used either of these TVs with OTA programming.

I always thought the picture was a bit on the grainy side of things on this set, but I'm watching some football I recorded on the DVR earlier and it is almost like an entirely different ballgame, clear, colorful, excellent detail all that I thought was lacking. No apparent grainy effect, I'm wondering if it wasn't some sort of compression/artifacting from restricted bandwidth by the cable. If you were to see a picture like this on this set in the store you'd be rather impressed too.

Honestly it is the first time I've really really been impressed with the picture, maybe I was too quick to judge this set.

My DVI-HDMI no longer works with my HT30744. It used to work fine. Now my ATI card doesn't "see" the TV. If I go to "Force TV Detection" on ATI Control Center it will find the TV, but not as an HD display and I can't get the TV to display anything.

I tried reinstalling windows, and Checked my cable and PC at a friends and they both still work.

Anyone have this problem or know how it can be fixed?

Thanks

I never used the HDMI connection until just recently, even though I've had the TV for a long time now. I was never able to get the display to be widescreen, it always had the pillar boxes on the side, no matter what I did. I have little hope of ever getting this aspect of the TV to work at this point.

I watched Florida vs Tennessee in HD last Saturday.. and I have to say it looked GREAT. Since I never had the controller, I always had the zoomed in look (pix 4).. and HD didn't look near as good. It looked better than regular tv of course, but not like I had hoped.

Someone in my town is listing a HT30744 for sale.

They said they were trying to adjust a configuration value in the service menu and the picture went blank.

They are asking $50.

Anyone think this is worth it?

Any idea if it can be fixed?

Thanks for any help/ideas.

I have the 30" Sanyo. I want to adjust the width of the screen in the service menu. When I switch from Pix 1 to Pix 2 while playing my 360 I notice I'm losing part of the screen. Is this difficult to do and is it potentially harmful? I looked in the service manual and the steps seem straight forward. Can you have a test image up on the screen while adjusting it? I've had this TV for over a year too. Is adjusting these settings after using it this long going to be a problem?

It could screw up the set, I've not tried it. However the set has a built in overscan of between half and inch and an inch on the horizontal, dependent upon the line voltage. Most CRTs have some built in overscan to account for line voltage variations, that just seems to be what this one was designed with. If your line voltage is stable it probably is possible to shave off some of the excess, but of course you run the risk of blacking out the picture entirely and not being able to correct it. As far as running it, I've been using the set for quite a while and it hasn't really changed, so I doubt length of time run would have much if any bearing on it.

I've not read too many success stories doing what you are suggesting.

The more sub-channels a channel has the more the HD channel has to be compressed to make room for them. This reduces the resolution.

Still I never noticed that with the old Samsung TXN2771HF I had in there prior to this set, nor did I notice it with the HT30744. Think it was merely coincidence that they added the channels around the time that I switched sets that made it appear worse than it was. One of these days I'll hook an HD DVD player up to it and see just how good or not good it really is, I suppose I'll try this if Sears reduced the HD-A1 they've had sitting around and I pick it up for the other livingroom as I have a lot of movies for it, which would make it worth my while. Should I end up doing that I'll let everyone know how it looks.

This happened to me while I was in the menu and I almost freaked out... but cooler head prevailed and I just mentally retraced my steps and I got the picture back.

It will probably be possible to get the picture back but it may take a while to go through all the codes to see which is screwed up.

My suggestion is to go through each one at a time and adjust three up and three down, that out to get the picture back.

but its definately a risk.. is it worth $50.00
probably.

I'd buy it.

smack it on the left side or grab the top in the middle and rock it.

works for me.

I've been viewing HD on my32744 using the QAM tuner but tried recently to use a SA8300 from TW. I ran the setup multiple times and never got it to work right.

Either the SD material got scrunched and the HD was correct (usually when I tried a 16x9 setup) or the SD was normal and the HD got sent in as 4x3.

Has anyone gotten it so the SD is full screen and the HD comes out in the 16x9 with the black bars at the top and bottom?

I tried search and there is a section on it, but it died off before anyone really gave an answer besides running the setup again.

Thanks

It has something to do with putting the cable box in "pass through" mode.

Unfortunately, I don't have the box anymore to tell you where to find that setting. Look in the menu that lets you set the resolution coming out of the box...set it to pass through and that might do the trick.

I bought a Sanyo HT30746 in used conditions for a very, very low price and I want to connect all my old systems and a Wii, everything works except for something that bugs me a bit, when I press the menu button on my remote and the menu options appear on screen, I can't choose any of them, I just can't move between the different options to customize the settings to my own taste, specially the picture ones because color, bright and contrast look bad, I thought that maybe buttons in the remote are not working, so I tried with a Sony universal remote and the same thing, I can't move, I press the up and down buttons and I can't choose any option, is like the buttons don't work, which is weird considering that I tried with two remotes...Also, when I press the parental control button, nothing happens. I just want to know if there is a way to fix this, perhaps a way to calibrate colors, bright, contrast and all that stuff without using the menu?, Is there something I can check in the Service Manual? Can someone tell me where I can find it? Is this a sign of something more serious?? All help is very welcome.

Well add me to the list of owners with the color problem. I cannot remember if I have the 30" or 32" model. Also, my problem seems to be a lose of another color besides red as the picture first goes blurry and then turns very red and dark. Smacking the left side (only side accessible) of the case fixes the picture. My set is nearing 3 years old.

I called Sanyo and the service person said it is a common issue and the fix is to remove and clean the "converter". That is all he would say. He said the converter is part of the tuner. Huh? Which tuner? Color problem is same regardless of tuner used. Anyway, his comments seem consistent with cleaning "pins". So, I will open up the case and look for bad solder joints and clean all electrical "plug" or "socket" connectors.

I have worked on tv's and monitors before, but I cannot seem to remember the safe way to discharge the picture tube...something about screw driver under rubber cap/cup clipped to chassis ground...seems crude and potentially damaging.

I have had my HT32744 Sanyo for almost a year now. A few months after I first purchased it, I went into the service menu and corrected some for overscan. Now, quite a bit later, there is still a bit of overscan. I've delayed fixing it for some half year now (:P). Today when I went to go into the service menu to attempt to fix the problem, I wasn't even able to get into the service menu! I've done it before, on this exact set. However, when I try and enter the service menu now (by unplugging the TV, holding down the "VOL -" button on the TV itself, then plugging it back in), it always tells me to press the CH UP button to scan for channels. I'm not sure what's different this time, but if anyone could help, I'd greatly appreciate it. Getting this fixed would be nice. ^_^

Wow...2700+ posts since my orignial starting the thread! I've got this issue intermittently. Some days it will be fine, others I'll get the green tint that comes and goes. A gentle love tap to the side of the case will fix it on occasion. Anyway, can anyone give me some tips on trying to deal with Sanyo on this out of warranty? I assume the first step is calling Sanyo CS since it seems like thety are well aware of the issue. Is there an official TSB I can reference or something?

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.

They serviced my set under warranty the replaced it out of warranty. I had a 30744 and they replaced it with a 30746 about 6 months after the initial warranty expired. Just contact them see what they say, they were very helpful with me, even called back to make sure that I was satisfied. It is service like that that makes a repeat buyer. I was considering a cheaper 50 inch Plasma TV to upgrade my one 42 incher with in the one livingroom, Sanyo normally wouldn't have been something I'd have considered but thanks to their excellent service it is now something I might consider. That said the 30746 has been just fine. I have this TV in the dining room, same as I had the original, where they get a lot of use it is placed in the corner of the room so the depth of a picture tube makes no difference.

I've never really considered it to be a top tier set, some sets have a better picture, the picture is decent if you turn the over bright factory settings down. I'm not one of those die hard CRT fans either, I've got two HD CRTs (this and a Samsung), one LCD rear projection, one LCD flat panel, and one 800x600 LCD VGA projector which I guess would be considered EDTV. Still they weren't a bad value when they were readily available, you can still find some refurbs out there, some Wal-Marts probabaly still have some new ones (I saw one at one like two weeks ago). It is a decent way to get an HD set without spending a good chunk of change. I think I paid $281 for mine. Even today that is still $300 less than a budget LCD and I've had one or the other for quite some time. Technically the picture is better than a lot of the budget LCDs because the black level on many of the budget sets is obviously worse, as is the repsonse time.

I've been DVRing all the football games the last few weeks and watching them sans commercials on this set and it looks good on HD, not as good as the Sony in the livingroom, but still quite good and as with any CRTs you won't see a hint of motion blur with fast action, so in all I've been satisfied. I never bought the Sanyo due to recommendations of anyone, simply the cheap price and the location of where I was going to use it.

Unfortunately now they seem to be making only an SD version of the set, at least that I can find. It is not much cheaper, lacks many of the features, has an obviously worse picture (even though from what I can find it probably uses the same CRT, which seems like a waste of potential to me). If you see one of the HD ones floating around and are in need of a cheap set its not too bad for the price and what you get.

I just called CS and was told that Sanyo has been repairing/replacing sets with the "green screen" issue. The lady I spoke with couldn't say if they were still doing this or not but gave me the name and number of the manager who would know. He's on lunch now but I will be calling later today. I'll post an update once I have some more info. The manager's name is Harvey and he can be reached at (800) 877-5036 ext 1700.

UPDATE

Harvey was a nice guy. He asked me to explain what was going on and then said he'd need the serial # and should be able to fix it under warranty for me. Hopefully that means I can drop it off at a local service center this week.

You and what Army? :D

Does anybody still have a link to the service manual for HT32744? It seems to have disappeared.
Could anyone email me a copy please

This set is nothing. I previously had a 40" Sony XBR tube that weighed close to 300lbs IIRC. I am able to at least move this around the apartment myself. I'll definitely need some help getting it down the steps though.

I just spoke with Harvey again with my serial # and address/phone. He said they will locate a service center within a reasonable distance of me and fix the set free of charge. I don't mind having to take the set in myself, I'm just happy to have it fixed. I actually decided to replace it last week anyway so I now have a nice 37" Vizio in the bedroom. I'll be putting this set up on Craigs List as soon as I get it back.

You and what Army? :D

vladgur;
P.M. me with an addy and I'll send it to you.
It's 4.87mb

Dropped my set off at the service center yesterday. They said no worries, I've got full coverage and they'll take care of it. Should be a couple weeks by the time they replicate the proble, order parts and fix it. Sanyo CS has been a pleasure to work with, especially considering this set has been out of warranty for over a year.

I'm glad to see this thread going on. I'd still like to get the best possible performance from this actually good tv. I woould like to fix a couple of common problems including a bend on the top right of the screen and diagonal lines on during a dark black display. I am fortunately NOT having the green tint problem. Also if anyone has perfected using an ATI radeon card with this tv I could use your help as well.

I have one of the 32 inch TV's and I was wondering if I could just bring this into walmart and return it at this point. I wouldnt mind getting store credit but could someone let me know if this would be possible? I dont have the box anymore and the TV is a little knicked from moving it in and out of dorm rooms but its still very functional but a little too big for me at the moment and the green thing is really pissing me off at the moment. Do I just take it back to walmart and suprise them or is there someone I should talk to first.

Mr X was a nice guy. He asked me to explain what was going on and then said he'd need the serial # and should be able to fix it under warranty for me. Hopefully that means I can drop it off at a local service center this week.

Same thing happened for me- I guess it pays to be persistent- seeing as how the first time I called they said NO repairing under warranty due to the age of the set.

THANK YOU - SANYO!

I have a Sanyo HT30744 and have been satisfied with everything except the lag I experience when playing console games. I've tried all connections and that doesn't make a difference. Is there something that I can do to fix this issue?

Thanks for the info and posting!

Well, I called Sanyo after reading this topic. Contacted Harvey and he says something about infamously being famous on the Internet kiddingly. Serial number and I have to drop it off for a fix. He did add if it was the picture tube, I'm on my own but most likely the green screen problem is it.

Fantastic! And thanks to those on this topic that have been persistent. The way this was going, I'd get it fixed on my own and skip Sanyo pretty much as I've never had a TV blow until 5-6 years. ( My own is 8-9 years ) But this service makes me reconsider definitely Sanyo when time comes.

Thanks to the OP leading to Harvey and thanks to Harvey!

This is a post from a few months past, but it's happening with my set also, and started about 3 weeks ago. I've had it for exactly 2 years now, and what I notice is that if I squeeze together the plastic casing on the top of the set, it stops. It seems like something became loose and is... well... I have no idea what I'm talking about, but it seems to work. Of course the next day it will start up again. Getting quite annoying, but it usually goes away after a few minutes... I guess nobody has any further news on this...

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.

I everyone I just started having trouble with my HT373744 and a green tint to the screen I bought it through walmart with a extended waranty but I cant find the waranty but I see you all talking about a green screen problem I have to turn my green all the way down in the menu to be able to get even close to a normal picture is that what every one else is having problems with ? thanks

I just contacted the Sanyo service center due to the random green tint issue on my 30744. The guy I talked too said they would repair it under warranty, asked for my serial number, and said that they would call me back and tell me which service center to haul it too. I know it's heavy, and those stairs are gonna kill my back, but hey, the fact that they're gonna take care of it, I'm pleased! Didn't even ask me for purchase information which would have been a dog for me to look up! Thanks Sanyo!

Sorry to bump an old thread but could someone please lend me the service manual for the HT30746 model? I really need it, thanks.

Looks like I don't have to scroll through 90+ pages after all. I have had the same green tint issue as well as a few others with my HT32744 since almost day one. I can tweak the case of the TV and sometimes get it back to working. I bought a Repair Master warranty online after purchasing it and am very glad. This TV sucks! Horrible sound, the analog coaxial signal doesn't work although I only figured that out when I actually tried to use it just for testing purposes to find the green problem. I had a guy come out and "repair" it once a few years ago and then it started happening about 6 months later and have been dealing with it and the warranty ever since. Just got told that they will issue a "replacement" for it that is equal to what it is. My biggest question is, "Can it be another brand?" There seems to be tons of problems with all Sanyo tube TV's. The repair guy that came out the last time that issued the request for a replacement said there was no way he could fix the problem without putting major changes to the flimsy case it's in. The board don't have enough support and sag causing the problem, which explains why I could tweak the case to get it to work sometimes.

I am experiencing an audio issue with my HT30744, one that has been described by others, where it sounds like wind in a microphone and you jiggle the cables plugged into the tuner a bit and it goes away or gets worse. I've actually had my picture go black on me too.

I contacted Harvey ("Hi, is this Harvey? <Yes> I got your name from the AVS forum... <oh man> says Harvey") and got a totally different person than what you guys have been decribing. He was no help at all and basically left me with the option to take it to a service repair shop. And the only one he could suggest was an hour away from me. I live in a very populated area (1.5 million +).

I'm trying to control myself from not ranting too much but I am really pissed off. I bought this set after reading the many great stories about it on this forum and the set is not even 3 years old. The set has not moved since I
installed it so it hasn't been dropped or mishandled.

Anyway, what I could use from people here is a possible solution to this problem, one in which I can fix myself.

For what it's worth, Harvey said he has been given the go ahead to fix sets with the green tint issue, but there hasn't been enough people experiencing the audio problem that I have, so he will not cover this under warranty. He didn't even offer to look into it or have any educated guess to the problem.

It seems to me that if the tuner board doesn't have enough support and sags causing the green tint issue, then sagging could also cause wires to cross giving audio distortion too.

Has anyone else had audio problems like this?

EDIT: Apparently cleaning the contacts can help... Can anyone tell me how to discharge the picture tube.

Does anyone still have the info on the QAM kit to enable the QAM tuner on the HT32744? I can't get it from Sanyo anymore (they told me I was out of luck) and now my cable company finally has some stations I could get if I could enable the QAM tuner. Any help would be appreciated!

Hello everyone and thanks for the great posts.

My set goes dark periodically. One poster suggested a tap on the cabinet above the A/V connections, and that does indeed restore the picture ... until recently. Now the screen is dark more often, and the trick doesn't always work. I checked IC711 as suggested by one poster, but that one seems to be soldered solidly. I don't see obvious bad solder joints.

Does anyone have any suggestions as to what may be the problem?

MANY THANKS!

I remember reading about corrosion problems on the tuner board on this set. Search this thread for "clean" or "contacts".

I can't believe this thread is still getting replies. My 30 inch is still going strong. Although in a way I wish it would die so I could have an excuse to get a real TV. Anyone interested in buying it?

My 32 inch has never given me a problem from day one.

Except for the poor speakers, which haven't been used for a couple of years.

I read through this thread and its predecessor a few years ago and crossed my fingers that I didn't have the problems that some have had.

This tv has been great.

Whenever I get the hankerin' to buy a new set, I see inferior pictures or extravagent prices.

But I don't think I will be able to hold out much longer. Cheap LCD's are looking decent. Plus I want something new and big.:D

I agree with the quality of this TV...i have had it for almost 4 years now...I too am pondering an upgrade to a 42" 1080p LCD. One issue that just came up recently is the lack of HDCP support. I have just recently attempted using the HDMI for use with somthing other than my HTPC (using DVI-HDMI). This has been rock solid for 720p use, but recently I have attempted using an upconverting DVD player I have (HDMI) as well as an AppleTV. Both are having issues getting the HDCP working. The ATV gives a very clear message that my device doesn't support HDCP. Also the DVD player never syncs, & gets the symptoms the DVD manual states will happen if the monitor doesn't support HDCP.

Is there anybody out there seeing the HDCP issues I am? I haven't done a full on trouble shooting effort, but wondering if I missed anything obvious.

FYI -

I just phoned Harvey with Sanyo (1.800.877.5036 x1700) using the info from previous posts on this thread. He told me they would repair the 'green image' issue at no cost to me (presuming the issue is not with the picture tube). He forwarded me to a girl named Jennifer (didn't get her extension) and she looked up a service center in my area immediately. She indicated they would fax my information to the service center and I could take it in for repair ASAP.

I bought my set 3 years ago.

Thanks to all that posted this information on the thread!

I was able to fix my issue of sound static and picture loss with my HT30744. Not sure if this is related to the green tint issues that people have been experiencing.

I fixed it by either opening up the case and cleaning the dust out or solidifying the tuner card with more screws... because I did both.

Funny that Sanyo only used 2 out of 6 screws to hold the tuner card in.

I noticed this after taking the cover off... there are really 6 screw holes to hold the tuner card in. The other 4 holes are covered with the sticker that shows the L and R for all the plugs... if you gently push with a pencil (or some such object) on the sticker in back you will find indentations where the other screw holes are clovered, just put some more screws in to solidify the card. Mine is very solid now compared to before, the plugs don't move at all now.

I assume Sanyo didn't use 6 just because some of the holes are right where the L and R are on the sticker.

I think my analog tuner blew out. My screen goes dark when I set the tv to that input and I don't get any video or audio. Has this happened to anyone before?

Hey Guys,

I just got a green tint the other day on my Sanyo HT30744 set. I wanted to look at something, so I moved the TV out, and the screen gave off a green tint.

Some of the things I've done to "fix it" are:

Move the TV around, sliding it from side to side, unplug the TV and then plug it back in, and rock the TV set.

All of these "fixes" only last for a short period of time. Maybe 5-10 minutes. Am I doomed to spend more money on a new TV? I really don't want to do that right now.

I'm sure others have had such an issue, and can give me a hand. Thanks for the look and help guys! :)

Well I talked to Harvey today and he wasn't able to be as helpful to me as he's been to some of you. I told hime about my pincushion/bending problem in the top right corner of my set. He said that that was an issue that couldn't be fixed.. :(


Then I asked him about fixing the digital tuner for Qam cable. He said that he could send me the disk but he didn't have the cable. He then said that I should ask one of my fellow AVS'ers for the cable.


So if anyone has either the service manual for the 32744 and/or the Qam enable cable I'd sure appreciate it. I'll even send the cable back to you. I just wanna try and make the best out of this tv finally. My goal is to turn it into a secondary htpc center in my computer room.

I saw that too but its for the 30" widescreen model (30744), not the 32" fullscreen (32744). Thanks anyway though. I didn't think any still read this thread.

Afroteddy send me a PM with your Email addy and I'll send the HT32744 service manual.
Its about 5mb in pdf format.
Don't know anything about the cable.

A fellow named Jimdoo was the last reference I could find. He is still active here. Send him a PM.

My story ...
My HT32744 was bought around Feb 2005 from Walmart.
It started showing intermittent green about 4 weeks ago. I found this thread and contacted Harvey at Sanyo.
He was very helpful and faxed a repair authorization to a local repair shop. They did the repair in 2 days. They told me they had already done a few for these TVs and thus had the parts in stock.

Really a big thanks to Sanyo.

I plan to write to them to thank them. I hope a few of you do as well.

Hey, does anybody have ANY other contact (email?) info for Harvey at Sanyo (1.800.877.5036 x1700) from the previous posts??? I've been trying to get a hold of him since June. Nobody ever answers that extension. Everyone else that I explain the situation to has no knowledge that they are fixing out of warranty televisions. They've taken my info before but nobody calls me back. It's so frustrating and I would assume the longer this takes there's a chance they will no longer cover the issue.

Well, first the problem. I've had an HT32744 since the fall of 2004. In addition to the color/green tint problems, now the HD tuner has stopped getting signal. There is officially no signal either over the air (bunny-ears w/ amp) or over the Cox cable, which they say now has free HD content. Has anyone else had this issue with these sets? Is there a fix? Help....

I'm really mad at Sanyo. I spoke with "Harvey" over email and he said that, in spite of my have had the issue for a long time, Sanyo was no longer helping to fix these sets with the green tint and color bleeding issues. I said it would have been nice to have a recall, b/c I didn't find out about the ubiquitous nature of the issue until it was too late. I just thought that my set was having a one-off problem. Now, with no digital tuner, the thing is essentially a boat-anchor. So, I'm here to say that Sanyo products are trash, the company is trash and I'll never, ever buy anything Sanyo again!!

In the meantime, can anyone help me with the digital tuner? Am I just missing something obvious?? Thanks to anyone who still reads this thread!!

-Ryan

Well, I finally got to speak to Harvey...been trying since the end of June. Of course, he said that he was only allowed to extend the repairs until June 30th.

Was there ever a clear idea of what actually needs to be done to fix the green tint issue? Was it really as simple as cleaning contacts?

Hi all,
Just out of curiosity, how many folks Tv's are still working great. Mine is and it's 3 years old. I just wish it could lose some weight. LOL.

Mine is still working although I don't use it very often. I had one problem with it where the picture was very fuzzy with both the digital and analog tuner. I carried it to be repaired, the repair guy didn't find anything wrong with it, I brought it back home and it has worked well every since. I have no idea what the problem was or if it will come back. My guess is that it will pop up again but hopefully it won't be for several more years. Even though I like this tv it is very big and bulky compared to lcd's so I wish that I had waited one more year and gotten an lcd instead.

Mine's still going strong after 4 years. I did replace it as my main TV this past spring and it's being used now for mostly video gaming/secondary HDTV but it's still being used daily.

I gave mine to my brother-in-law last year. He had the "green tint" problem fixed in Mar/Apr this year and it's been going strong ever since. Great set, picture... just a lot on the bulky side.

I retired my 32" to the basement a couple of weeks ago. I upgraded to a 52" LCD 550 Samsung. The only issues I've had with it was the greening blurry issue. My fix was to put a couple of gator-aid caps under the front of the tv. This helped keeping the blurry greenies away.

New to the forums. I have the HT30744 model and it appears that my screen has a slight tilt on the upper-right corner. Is there a way to fix this?

Mine is very solid now compared to before, the plugs don't move at all now.

I assume Sanyo didn't use 6 just because some of the holes are right where the L and R are on the sticker.

This gave me the confidence to open mine up. I too removed the dust that I could. Did not add any screws, but I made sure everything was connected solidly.

I had been having issues with Greening, until my set went black and I only received audio on all inputs.

Finally I found a 'H' and 'Screen' adjustment knods that are not accessible from the outside. These alone may have fixed my problem. I now have a perfect picture, though honestly I will not be sure about the Green issues until I use my HDMI connection. My greening issues seem to be connected solely to the HDMI connection.

Thanks, it was time to either fix it or toss it...

Anyone else having intermittent "green" issues with their Sanyo? Mine started about 3 months ago, and are intermittent. It stayed for a while, then I smacked the back of the TV and it stopped. About 2 months later, it started again, but comes and goes.

I don't really want to crack open the back of the tv, but if what was just described above is pretty easy, I'd try it.

Also, my screen is basically zoomed in too much. I don't see all of the ESPN logo that they put down the left and right sides of SD content. Can I adjust that with the H and Screen knobs that you mention above?

Thanks in advance!
Tim

Mostly this is too thank the many previous posters.
After a few weeks of green and reading various posts I tried lifting my set from the front right corner. Red flashed by intermittently. Holding it up I placed about a 3/8 inch cardboard shim under the corner. This seemed to help. But I noticed that the back foot was no longer touching the table top. So I pushed down the plastic case at the back corner of the set. I felt something settling inside the set. This having worked well I decided to pretty up my repair by shimming up the front right-hand leg of the set. I checked the table top for level and found that the dropped corner had resulted in the top being warped or twisted as a result of the sets considerable weight and my wonky floor. Sorry for the long preamble but it appears that this process reseated a board or component. The set has been working fine for 3 or 4 weeks now. This seems to confirm that re-seating of boards or modules may help. However I won't even take the back off my set until it acts up again. What a shame it would have been to send this beautiful TV to a landfill!

I was told by a TV repairman that the HT32744 "green blob" problem is due to "shadow mask doming" caused by an area of white in the picture (e.g. the ice in a hockey game etc.)

See "What is doming?" (sorry, forum will not allow me to make this a clickable link):

So were you able to get someone to fix it? Did they come to you (I dread lugging that TV to the car and back in)? How much did it run?

Just picked up a used HT30744 for $200. Previous owner said that it occasionally went green, but hitting the side of the TV usually seemed to fix it.

I took it apart and added solder to all the "Red" points mentioned in this thread, as well as a few other bad-looking spots. Watched 3-4 hours of TV last night and no trouble so far. As long as the colour stays, I feel it was a pretty decent deal.

I feel that I've missed my chance on this, but does anybody know how to get a cable to enable the qam tuner on this beast? Maybe even some schematics? I'd try to build my own at this point, if I could get the disc (or disc image) to configure it. I've got the ht32744...

Mine has the same problem as well as some blurriness on the left side. I think mine is in need of some calibrating but I'm too chicken to mess with the service menu so I'm gonna take it to a repair shop and let them do it.

Glad to see there are still some people using their tv and still in this thread. mine is still going strong and is finding new life in 09. Gonna see if a service center can calibrate it for no more than $100. I thinm my analong tuner burned out but I got a hd cable box so thats not a concern anyway.

Let us know what you find out...I'd deal with the transport for $100, but not much more.

I read somewhere in this link that Harvey had an email. Can anyone provide it?

Just lost the picture, have sound but no picture on any input. I ordered an LCD last night, but wanted to hear if the solution was relatively easy. If so, I will put this TV to secondary use.

FWIW, jut before I lost the picture, I would loose sound when switch channels. Resolved that problem by changing from HDMI output to fixed on my cable box...only lasted about one week, then no picture...but I still have the sound by golly.

Either easy fix or it is going to the recycler.

I'm praying that mine blows up. Can't get a new LCD until this one bites the dust. I'm kind of like that new commercial where people are trying to deliberately destroy their TV just to justify a new one.

I thought this TV looked pretty good when I first bought it years ago but now I realize it looks like hell compared to the 1080p flat screens all my friends have.

Mine got broken once. Had some picture but very bad and getting worse and worse. Sometime if I shake the TV back and force a few times, it will get the picture back to normal.

i opened it up and reseated a couple of connectors behind the big tube and it's now working again.

But do remember to unplug the AC cord before you do that because there are a couple of component still have power even if the TV is off.

Just my 2 Cents. Good luck.

Fixed it last night. removed, cleaned, and reseated the vertical component boards (audio, video, tuner) and all is well.

Excellent job, dframe3!

has anyone got automatic time adjustment to work after the switchover to HD?

Anyone want to buy my 30" ? LOL

I finally got a new TV (42" 1080p LG). My wife tells me we should take the Sanyo and put it in the bedroom but after getting nice new bedroom set I don't want that beastly CRT making it look junky. I'd like to eventually put the LG in the bedroom on the wall and maybe get a 52" during the BF sales.

I can stick the Beast in the basement but I'd rather get rid of it completely.

I am brand new at this so I hope that I am doing this right.

I've got some kind of a copy protection issue between my JVC DR-MV100B DVD/VHS upconverting recorder combo and my Sanyo HT32744 HDTV.

I purchased the TV in January of 2005 and the DVD recorder in August of 2008. The two units are connected by HDMI cable. For the first 8 months everything was lovely. In April of this year I played a DVD made at my daughters workplace. It contained video taken from the National Geographic channel which related to a weapons system component which they had developed. After playing the video I can no longer play copy protected DVDs or tapes. All I get (with the exception of an opening screen on a couple of DVDs) is a blue screen. I can play any of my unprotected DVDs and tapes with no problem. All other functions seem to work fine.

I have sent my DVD recorder to the JVC service center for the 3rd time. The first time they replaced the entire DVD carriage. That didn't help. The second time they tried to get the blue screen and couldn't. The third time I sent some of my DVDs and tapes back with the unit. They work fine for them. They have sent me one of their recorders, identical to mine, to try. I get the same blue screen.

When I contacted Sanyo all they said was that it had to be the DVD unit.

I don't know if my daughter's DVD triggered the copy protection issue or if it was coincidence.

My question is: does my Sanyo HDTV have firmware that can be upgraded and if so how do I find out if there is an upgrade that addresses my problem?

Have you checked using another tv with an HDMI connector?

I haven't. I only have the one Sanyo HDTV. However, the JVC tech I have been dealing with tried it with everything he had and it worked fine. Both my JVC recorder and the JVC recorder that the tech sent me get a blue screen when playing copy protected media on my Sanyo. At the moment I have the tech's recorder and he has mine.

Hello everyone!

I have a GeForce 9400 GT hooked up to my Sanyo-HT30744 TV using a DVI to HDMI cable. The TV is supposed to use Component 3 audio input for sound on the HDMI channel when a DVI device is hooked up. When I uninstall the driver to my video card and/or when my PC is booting up and going through BIOS, the HDMI channel displays the notification that you must use the Component 3 input for sound, ext, and works like is should. When the driver is installed and when the boot process gets to the Blue Windows start screen the screen flickers then the TV thinks the HDMI has sound coming through even though it don’t.

Can anyone please help me on this?

I have messed around with the TV and the NVIDA settings and everything and NOTHING.

Is there any pins I can break off the DVI end to make it work like it should or anything I can adjust in the service menu?

I found an HT32744 on Craigslists for $50. I had him hook it up, and it looked good. Got it home, hooked up to a DirecTV hr-22. Looks great. This is for a bedroom. I have 3 other newer HDTV's. But for $50, I'll take it.

Quick question, that probably has already been answered, does it convert 720p to 1080i?

Nope, no 720P capability. Only 480i, 480P & 1080i.

Nope, no 720P capability. Only 480i, 480P & 1080i.

Thanks for the quick response. Then what does it do with 720p sources? For instance, I was under the impression that ESPN was 720P. I get it fine with my DirecTV HD DVR, connected with HDMI.

Nope, no 720P capability. Only 480i, 480P & 1080i.

? Mine displays 720p just fine, fed from my WDTV over HDMI. In fact it looks better than being fed 1080i.

Hmmm, just checked it with my E* Vip622 via component and 720P works fine with it, although it still upconverts 720P to 1080i.

It must have been an issue with the Comcrap Motorola boxen's 720P output back in the days that they were my MSO.

I get the green screen thing until it warms up. Any way to fix it?

Also, If I run 720 or 1080 on by brighthouse hd box, it's squished funny. I have to use my Sanyo remote to switch from normal to letterbox on several channels. If I run 480 only it's all automatic. Is there a fix here as well?

Thanks!

I too had the same problem where my HT30744 TV would lose its color. My mom's HT32744 would have the same problem too. They both are refurbished models bought at Value City Dept store. If I gave the cabinet a good hit it would mostly fix the color, but it could also make the picture go fuzzy too, a clear sign of just a loose connection somewhere.

So after my wife telling me she was sick of this almost 2 year problem and she was going to buy a new TV on the weekend, I figured I had nothing to lose. So I took the rear cabinet off, unseated the card mounted on the picture tube, applied a little dielectric grease on the connector on the card and reseated the card, removed, re-greased and reattached the card. I have had no problem with either my or mom's which I did the same to since! This is an easy fix that anyone can do. The hardest part is moving the TV and reassembling the rear cabinet. Do not pull the cabinet back out more than you have to, to ease the reassembly of it.

I just started losing the red color every once in a while. I'm going to try this. I'll let you know. Thanks for the tip

Hi,

Was just given a HT32744 as a freebie. Had heard about some random color loss from previous owner which I assumed was just a cabling issue. Haven't seen it happen yet myself. I too might consider the cleaning/reseating suggested in March and June 2010... Thankful to AVS for continuing to provide this very helpful information.

Now if I could only find a cheap Sanyo FXYA remote (or universal remote/codes) that would let me properly access/control the onscreen menu and the advanced features like Picture and Picture... I'd be a very happy HT32744 owner.

I bought the 27" version (no HDMI) about 4 years ago. No problems so far (knock on wood).

Glad to hear it. Your model didn't use a Sanyo FXYA Remote did it? Still looking for a remote/codes that will let me navigate the menu/features.

My Sony AVR-2100 seems to allow me to access much of the HT32744's features but I can't seem to navigate the on screen menu properly. I can go between the antenna tab and Channel Search but navigating to other tabs or scrolling up or down the screen (and selecting items) seems blocked.

Anyone with ideas on what other options I might try? Got a Sony WebTV Keyboard (and RCA UltimateTV DVR Keyboard) I'm going to try and use (they both have TV Remote functions). I might also try another Universal Remote.

On my remote in very small numbers, it has: "GXAB". I bet it could control your model, also. I got my set on clearance from Wally-World; you could check a few stores to see if they have any leftover Sanyo remotes laying back in stock in somewhere.

Hello folks, just joined here although I read this and other threads before I bought my Sanyo HT30744 in Jan 06. Hard to believe I am closing in on 5 years with that beast but haven't had any problems that a solid smack didn't fix *LOL*

Anyway, the reason I finally signed up and am posting is I have been watching mostly OTA HD signals and had Canadian satellite TV using composite cables and switched over to the local cable company and they have given me a Pace HD-DVR to use. I went out and bought an 1m long HDMI cable and when I power up the tv, the video and audio are great but as soon as I change the channel on the box, the new channel loses audio. If I switch back to the previous channel the audio is gone from there too. The only way that seems to fix the problem is to shut off the tv and then power back up. Is this an issue with the tv, the hdmi input/cable or the cable box itself? Any solutions would be most welcomed.

"I feel that I've missed my chance on this, but does anybody know how to get a cable to enable the qam tuner on this beast?"

Call Sanyo. The original models had a built-in tuner, but they dropped it with a promise to install it if you need it. I think that promise morphed into "we'll send you the conversion kit."

It's the HDMI port. Mine does the same thing and I have DirecTV. Sometimes it powers up with sound, sometimes not. Sometimes I have to power-cycle several times.

Is there a fix for this or should I forget HDMI altogether and stick with component cables?

Is there a fix for this or should I forget HDMI altogether and stick with component cables?I am not aware of a fix other than a repairman. When you power up, does your screen tell you to use component cables? Mine has a red message telling me that. I don't even know what it means. Is it saying use all component cables or just sound?

Hi, my parents have the HT32744 and today it suddenly started to display some messed up color. I really don't know how to describe it, so I took some pictures. As you can see, the picture looks muddy and dark, it's like the backlight is dimmed on an LCD. And I'm already taking the pictures with the contrast and brightness turned all the way up.

Anyone know what's the cause of it or if it's fixable? I can do simple soldering if it's just replacing something simple. Thanks.

Hi,

Not sure what you'll need to do but I have some questions anyway.

Just for clarity... what ,if anything, have you already checked/tested to narrow down this issue?

For example have you ruled out problems with your various input cables and/or the inputs themselves? Does the TV's display have this problem on all inputs or even no inputs (where there is no signal)?

Sounds like you already adjusted some of the TV's display settings... have you attempted a Factory Reset/Restore of the TV's settings? (I think this TV has that option right?) Just in case there are some funky options that might be giving you grief.

Good Luck. Hopefully this forum will be able to help resolve this issue.

I have tried the coaxial, RCA and component input, all of them are showing up like that. I also tried the reset button on the remote, is that the reset you're referring to? Thanks for the reply.

I don't have a factory remote so I'm not exactly sure if your "reset" button actually performs a reset to factory default or not. When I was performing a remote code search for this TV on one of my remotes I got a prompt to rescan for channels and a restore factory default (I think).

If I had a factory remote (or one that gave me proper access to the On Screen Menu) I could tell you what you may have to do...

I assume a "slap" to the TV's casing (as discussed elsewhere in this thread) has not "restored" the TV either?

I've read earlier in this thread that there may be a board you can try and pull/reseat to otherwise "fix" what a "slap" might only temporarily resolve. If this is the same issue others have had with loss of certain color(s). Not sure if that is the same issue you have.

Thanks for the info. I tried slapping it today, it didn't work. I'll take it apart this weekend and reseat the board. Just making sure, you guys are talking about the board connected directly on the back of the tube right? I'm going to unplug the TV tonight and let the power drain for a few days.

That is what I was thinking. Not sure it is going to fix your specific problem but if you're willing to try it... I'm not sure it can hurt to try. (Worst Case is the Parents get a much less heavy/oxy LCD or Plasma TV)

A very good idea letting the TV sit unplugged for 48 hours or more. Then it also wouldn't hurt to brush up on tips to avoid electrical/static shock. Insulate yourself from ground by standing on a non conductive surface like a block of wood. Discharge Static Electricity from youself before working on the inside of the TV. Avoid touching metal when possible, use insulated tools, etc.

Good Luck and if you have your camera handy I'm sure everyone wouldn't mind seeing photographs of the process and anything odd you might see inside.

Can't find a solution to this anywhere. Apologies if I post this to the wrong forum. My Sanyo HT30744 flashes a black screen annoyingly for over five to ten minutes before finally allowing the picture to stay on when the television is turned on. It seems that once the TV is "warmed up" it works great. We've had the television for years and just noticed that it has started this and it's getting progressively worse over the last six months or so. I can't seem to find anyone that has the same problem. Any help?

Besides the "warm up" seeming to fix this issue... what other troubleshooting have you tried? Is this problem on all your inputs or just some? (Bad Cables or Source?) Do you have unaffected audio while the screen blacks out? (Narrows it down a little)

Have you tried turning the TV on via Remote and Power Button? (Not sure what difference that makes. But the results might be interesting if different.) Does "slapping" the TV do anything? (As it supposedly fixes other "known" issues with this TV.)

Do you have a way to test the power receptacle you are plugging into? (A multi-meter to check voltage and continuity) You should probably see voltage around 114 to 126 V (I've usually seen 125V on outlets I've tested). Anything significantly higher or lower might be an issue. Let us know if you get any "odd" readings.

Along that front have you tried switching outlets? A loose or bad contact (check for how much "wiggle" you have or if it falls out of the receptacle) might prevent the TV from drawing the power it needs to start up properly. If a different "good" outlet works then bypass,repair, or replace the "bad" receptacle.

Good Luck,

I asked a friend that knows a lot more about electronics to take a look at it for me. He adjusted the focus and said it was unresponsive. He also removed the PCB at the back of the tube and reinserted it for me, it didn't fix the problem. His guess is either this part (some kind of voltage regulator) or the tube is bad.

He also said it could be one of the signal processing boards, so I took pics of all of them. If anyone knows which one controls the color please let me know, I'll see if I can find a replacement and try that too. Thanks

Is there a fix for this or should I forget HDMI altogether and stick with component cables?That would probably solve it. I switched to ordinary RCA RGB plugs and it's OK now. Except it took me an hour to figure out that the video 1 input was dead. The brand/model TV set seems to have an extraordinary number of defects that show up after the warranty expires.

Well I am back and now it is a different issue in that the the ATSC tuner seems to be messed up although the NTSC is fine. I had 20-some channels logged into the memory. From the analog channels going up I see Ch 2 with the PSIP into. I am missing the second channel 2 I had. I get a D 03-1 and D 03-2. The I get 4 and 5 with PSIP then it goes to Video 1. If I go down from there, get 57 and 51 then back to analog. If I manually enter a channel number then I see more channels. With the PSIP I see 9, 17, 21, 23, 25 and 29. Without I see 8, 10, 12, 15, 19, 24, 30, 35, 47, 48, 50 and 51. Everything else seems fine. Is it time for me to make the upgrade to a flat panel with built-in tuners?

For all those who have a V5 set with the QAM tuner disabled. I contacted Sanyo Service and they sent me a cable and a cd and I was able to enable the QAM tuner using my PC. Just call Sanyo Service and ask for the QAM upgrade and they can help you out.

Sanyo is telling me they don't know what I am talking about. They can't even find my serial number in their database. Rather than fight that battle, does anyone have the cable and CD that enables the QAM tuner in the Sanyo HT32744? I would really like to get my hands on it.

So just to clarify... you own a V5 (2005) model with a disabled QAM tuner?

You might want to give them another call back... You might not have registered your TV so it wouldn't be in "that" database... but they should have technical/troubleshooting support based on the Model.

Might just have been a case of CSR Roulette and you got Red instead of Black. Flip that coin again and see what happens.

If you don't find the hardware/software here... don't think of it like a battle with Sanyo... try and explain you wish to enable the tuner and that you need a cable/software to do it. If they aren't finding it... then ask to be transferred to another department that might deal with these Technical issues.

Good Luck

Hi,
My 7 year old Sanyo HD Tube TV may be nearing its service life...
The problem is that after warming up, the picture turns into glaucoma vision. The effect is intermittent and does not always happen. Banging the plastic case has no effect!
The service manual (linked on this thread) seems to provide a significant number of on screen technical adjustments...
May any of this help, or is time to move on and replace?

Thank You

Yes.

Or worse. It's obviously an offshore support group. I called three times, got three different reps and three different line qualities, none of the six very good. Two of them insisted there were no QAM tuners before 2006. The box is definitely registered.

Another tried to send me through the canned routine to scan channels, but failed to tell me some very basic stuff like where I should set the Sanyo input. Actually, it was worse than that, she first asked me to get my remote, never mentioning that she wanted me to be in front of my TV. I don't want some know-nothing running me through dummy drills, I just want to know if the kit is still available and what equipment is needed on my end.

Quick question. I understood that the "kit" was a cable and a CD. Which connection on my PC is utilized to talk to the Sanyo? I frankly don't see any common plug/jack.

Thanks for the quick response. I would have answered sooner but my SuddenLink (more like SuddenCrash) has been down for eleven hours.

Wow! My tv screen went green during the Superbowl right before the halftime show. I know this is a common issue but I don't know what the fix is. Is the tv even worth getting serviced? I think it's the best looking hdtv set that I own even now but now that it's showing all it's common symptoms I'm not sure if I should continue to hold on to it. Then again, my budget won't allow me to get a 32" tv that looks as good as this one does. :(

Can you seen the green tint in my picture? Also my picture slants up to the right. I have always had this problem but I'd still love to fix it.

Mine just got the green tint as well a couple weeks ago. I don't think they are worth fixing anymore - I'm just waiting for electronic recycling day to dump mine off.

Yum.. I am eating my words. It is tasty!

This leads to a question. How do I turn-off the 3:2 pull down feature if my DVD player is doing the 3:2 pulling down? Would that redundancy casue problems? May be Sanyo has automatic sensing capability to turn on/off this 3:2 pull down feature.http://www.******************/zhaojh.jpghttp://www.******************/zhaoht.jpghttp://www.******************/zhaogd.jpg
