I asked this earlier in the thread but haven't received any answers so I thought I'd try again.

Would anyone happen to know when and if Sears will start selling this TV (A750). Right now they're selling the 87S (only) and it's recently been heavily discounted. (from what they usually sell it at) This gives me hope as to them actually carrying the LED models as well as them getting the A750 (because of the discount in price on the 87s). However I have heard every answer imaginable depending on which sales person I ask.

The reason this is important to me is because Sears is the only option to buy this TV as I live in Hilo, Hawaii. (Online retailers won't ship TVs here and we have no BB, CC, Frys, ANYTHING) I also would like to know because if Sears is not planning on getting the 2008 models I need to buy the 2007 model before it's sold out!

Thanks a lot.Since both BB and CC has the HL61A750 listed, most likely Sears will too, I would check with the store, as Sears doesn't always update their web site to show what they stock.

Hi,what do these new led set's picture quality look like?Are they better than any of last years samsungs dlp's?
I am getting ready to preoder the "67 from Abt's.This will be based largely on what users have to say about the picture quality.I figure this set may hold me for a few years until oled is more affordable and larger size's.
Thanks everyone.Should be somewhat brighter, although the 2007 models were pretty bright. The 40% increased brightness allows Samsung to produce a 67" model this year compared to 61" last year. May not be a 72" but close enough for most folk. ;)

I always found the 2007 models PQ to more then adequate, and the 2008 series 6 and 7 models are all HDMI 1.3a compliant with xvYCC and deep color support, unlike the 2007 xx87s models. (HDMI 1.2a)

Have you tried one of my old favorites: "Can you order one for me?"
Maybe they can throw one on the next ship or cargo plane headed there.
They carry the brand so, just cause they don't have the model you want doesn't mean it is impossible to get. Befriend a salesperson or manager.
You sound like a motivated buyer! You sure don't need a sale price I guess. Maybe you even have MORE to offer them if thet'll get one to you...if u know what I mean...actually I don't even know...u fill in the blanks!:D

HDMom,
You probably are referring to my post about my initial reactions/review of my HL61750A as the review included the stand using the 56" version.

For me, building the 56" version saved me at least 6" of width space which I wanted & needed :). As I reported, the 56" version of the stand was a perfect fit for the 61750A. The stand & TV almost looks seamless. I only have 4 components on the 2 glass shelves. My Denon AVR-3808ci, Tosh HD-XA2, Comcast cablebox, and a Belkin PF60 power conditioner. Keep in mind the recommended weight capacity of each glass shelf is 50 lbs. Silly me had to test this out by gently placing my AVR & power conditioner on the same shelf. That's about 65 lbs. Don't overload the shelves! I immediaetly noticed the shelf bowing. I had to carefully layout my components because of the weight. My Denon alone is 40 lbs. and my Belkin power filter is 15.5 lbs. I couldn't put both on the same shelf.

Stand's Con The only negative aspect I found about the stand (to me anyway) was the top shelve height was limited because of the support beam that you have to install on the bottom side of the top, TV shelf. I really wanted my Denon reveiver to sit on the top shelf but it wouldn't fit:( My receiver stands 6 3/4" in height)

Personally, I don't see any advantage to using the 61" version. The glass shelves are the same size (43 5/8" w X 15 13/16" d) regardless of the cabinet size, so you're not gaining any real useable shelf width space. The stability of the 56" stand is fine with the 61750A on it. Again, regardless of the stand size, the top shelve holds a max of 100 lbs.

I hope this was helpful and enjoy your 61750A!
Eric

-------------------

I will have to disagree with Eric. I just got done putting together the stand, which was a three hour job due to the many interruptions (dogs, phone, etc). The stand looks nice, but is flimsy in its construction. I am used to the wooden stand that holds my Mitsu 57731. It is heavy and rock solid, just not wide enough to support the 61A750. Not so with Pinnacle Design's TR500X3B, which is specifically designed to hold either the 50", 56", or 61" Samsung. It looks good, but that is the only positive thing I can say about it.

I disagree with his assertion that constructing this stand for the 56" TV is fine for the 61A750. If you do that, the TV overhangs at least 2" on each side, which is not a good thing. If you build the stand to actually hold the 61" set, there is no overhang, and therefore nothing to bump against and knock off the stand. If you get a 61" TV and this stand (which I don't recommend), construct it to hold the 61" set.

I don't like the stand, not only because of its flimsy construction, but because it is not deep enough to hold my Pioneer 1016 receiver, so it sticks out from the front about three inches. The two glass panes also aren't wide enough to hold more than two components each. Also, each glass shelf only holds 50lbs. Not good. :mad:

If I had to do it all over again, I would not buy this stand. Instead, I would buy something more solid, deeper, and with wider shelves that would hold more weight. :(

As for commenting on the TV, I won't be able to get all the components hooked up till tomorrow, but will post something then with my initial impressions.

Can anyone with the unit comment on the "hotspot" center issue that the CNET video reviews complain about alot with DLP? Can you tell how this one is with that?
Also, anyone know the 120HZ answer I asked before? The Samsung specs say 120HZ (color engine) but all inputs only up to 60! What's that all about? Are they the same spec item?

the 40% brightness is not over last years models but over other HDTVs. Samsung is very specific in their wording. I have seen a 750 series on display and they do NOT look any brighter. The Viewing angles are just as bad as last year.

Can anyone with the unit comment on the "hotspot" center issue that the CNET video reviews complain about alot with DLP? Can you tell how this one is with that?I presume this is the light coming from a "searchlight" at the bottom of the middle of the screen shooting upwards.

I had never read about or seen this before and it throw me for a loop. I only see it when you have a solid gray (light) screen and you are standing right in front of the set (looking downwards). From a typical viewing height I have never seen it.

Swapped out my 50A650 today due to the bowing issue. The guy at CC opened the box on the new one, and let me fire it up. I checked the grid test pattern and this one has bowing too, but less. Probably like an 1/8". I brought it home and started slowly working the top of the cabinet. A bit of light pressure inward in the center and outwards at the edges. After a bit, it seemed like the plastic was holding form a bit and most of the bowing is gone. probably about 1/16" now. Much better than the 1/4" I had before on the first one. It seems to me that the entire bowing issue is purely cabinet driven. I don't know if it will hold up long term, but it's good by me. If the 1/8" looked much better than 1/4. Amazing what a difference 1/8 of an inch makes/

Sears currently has the Sony A3000 models available on their website for delivery to your local store. I would assume that this includes your local.
I appreciate the suggestion. Not only is my heart completely set on the Samsung LED DLPs but I've checked and the Sammy LED DLP is the ONLY RP they have in stock as they are clearing out all other models. They say this district is no longer able to order the other models. As I've said they don't seem to know if they'll get the a750s though.

Since both BB and CC has the HL61A750 listed, most likely Sears will too, I would check with the store, as Sears doesn't always update their web site to show what they stock.

I have checked with the store several times. Every employee tells me something different. Even the 2 managers I spoke to gave me two totally conflicting answers.

Limited delivery available to Alaska and Hawaii for $99 per item. Call 1-888-955-6000 for more details.

Have you tried Crutchfield? I am a big fan of this company.

I saw this on the site but the "limited" scared me away as the a750 is a 61 inch. I thought that would take me out of the "limited" ballpark. I guess it really can't hurt to try. However, the flimsy build has me scared of standard shipping through a courier service rather than a freight container shipment. I guess I'll just suck it up and give them a call.

Have you tried one of my old favorites: "Can you order one for me?"

Actually I have and they have told me that they cannot order an item if it is not in their system. (They say it's not, I think it is.)

Thank you all for your replies and help. I guess I'll be crossing my fingers and giving crutchfield a call and hoping for a stroke of luck. :o

I really don't know the cause but on the CNET video reviews they kept saying "backlight", I think, which should be the regular LEDs or the main lamp on a non LED model. I never heard of the "searchlight" in one of these. I missed that if they mentioned it. Also, they just showed the screen straight on level when they said that, even tho it was hard to noitice the center being brighter. Thanx

Thanks Eric, this was just what I was looking for. I too can use the extra 6 inches as my living room is configured a bit strange. As for weight issues, I had already figured that my best bet would be to order an AV rack from Costco, thus the need for conserving space. There's no way I'd put my HK receiver on the TV stand, that thing is really heavy. Besides, I have 5 sources that I'll need space for - the AVR, PS3, XBox 360, Wii, satellite DVR. The center speaker will probably be the only item I'll actually put on the stand.

Thanks for your help!

ETA: Eric, any way you could post a pic or two of your set and the stand?

Here you go HDMom. I took a few shots and thought this one provided what I think gives you the best overall view of the stand & 61A750.

As I said in my first post towards the beginning of this thread, using the 56" version allows the 61A750A's screen (only) to extend about 2-3" on each side of the TR500X3B and 61A750's attached stand itself sits on the TR500X3B with plenty of space on each side before the edge (actually, there is 5" of room on each side)

I know another member, Kevin Rohrer indicated that he thought the exact opposite of my findings. Again like everything else, these things are subjective to each person, just like who thinks the 61A750A's case is flimsy, it's individual perspective. As I said earlier, I find the stand solid, each piece, legs, back, top are solid and heavy. All screws & bolts are solid too. My stand doesn't have any side to side or back to back wobble. Even if I disregard the fact that I got the stand for FREE, I still think it is an attractive, solid TV stand. But FREE does help;)

Cheers,
Eric

Kevin,
perhaps all the interruptions you experienced that caused a 1/2 hr. build to turn into 3 hr. project might have something to do with the quality of the stand. Maybe you put it together incorrectly? Either way, if you are so dissatisfied with the stand, why not return it and get a refund or exchange it since you said you paid for it.

Just a suggestion, it's also a good idea to do a little research. Even though I got my stand for free, I still measured all my components and then researched the stands dimensions, especially the shelves.

Good luck

Not always. If it is uniform maybe. I had a little at the top and moving the bezel as you described may have helped it (it was hardly noticable). And it helped at the bottom a little, but my bowing is not uniform (as the pictures I posted earlier show).

I had the shutdown issue happen yesterday while playing Rockband on PS3. Today I will connect the PS3 over component and continue to troubleshoot this. I hope amsung or Sony can figure out what the problem is and issue a patch.

I'll keep the board posted about my component input findings.

Have this years LED models dealt with the poor black levels (even worse than LCD) and the hot spotting from last year?;But when a DLP rear projection set is outperformed in its ability to produce deep, rich blacks by many LCD flat panel displays—including Samsung's own LN-T5265F............I have to scratch my head.http://hometheatermag.com/rearprojectiontvs/807sam5687/index.html

2. The room it goes in is bright and having a set with 60,000-hour LEDs instead of a 2-3,000 hour bulb will allow me to turn up the brightness without fear of having to replace it anytime soon.Changing the brightness has no effect on the brightness of the 'lamp' with any of these RPTVs', except when you change picture modes w/ Samsung (as long as it is the same as it was two years ago).

I never heard of the "searchlight" in one of these. I missed that if they mentioned it. Also, they just showed the screen straight on level when they said that, even tho it was hard to noitice the center being brighter. ThanxI called it a searchlight because the increased brightness widens as it rises up the screen. It starts very narrow at the bottom of the center of the screen perhaps an inch or so and widens to several inches before it disappears about halfway up the screen.

Again from typical viewing distances and angles I haven't noticed it at all but standing next to the set and looking down at a solid gray screen I thought what the heck!

Well, I have read as much as I possibly could about the 750. I was sold on the Sony KDS3000 before I found out that they would no longer be made and had to go another route. I walked in here and saw the HL61A750 for the first time. It was between the Mitz 65 and 73. It looked good, but, it also looked like the brightness was turned down. I am positive that this is the TV that I am going to buy. So after many many searches, Should I haggle down, or just take a road trip(from Pittsburgh) to Cleveland. Thanks for a lot of good research, I'm really glad I found this place.

The picture is a deceiving. You can get a much better look at it and the design from Crutchfield's web site here :
http://www.crutchfield.com/App/Product/Item/Main.aspx?i=305TR500X&tp=1321
There is also an enlarged picture and all the stand's specs.

The depth of the top shelf is about 15 1/2" which provides enough room for the 61750A's 14.4" depth. here's waht I said when I posted my first impressions abhout the TV & stand

"The TV's depth fit's perfectly on the stand. I have it pushed back 3" from the stand's front edge and the very rear of the TV extends less than 1/2".

Dumb question........I can't seem to find an answer (but,I think I know it already)

The HL61A750....does it come with a stand?

Also, concerning the HDMI cable. I saw several different speeds. 500/700/1000. Obviously the 1000 is the best, but, with this TV running from a Direct TV box, do I need 1000?

Thanks
BG

At Crutchfield the the 61A750 comes with the stand for free, also free white glove shipping. I don't know why, but the 61A750 isn't on the Crutchfield web yet but a number of us have purchased it by calling their 800 telephone number.

On the HDMI, it looks like you've been looking at Monster Cables products as those seem to be Monster product numbers, not speed numbers. IMHO, I wouldn't spend the money on Monster. Take a look at Monoprice.com. You can get a 6 ft 1.3a category 2 certified, class 2 in-wall rated HDMI with net covers, gold plated for $12.52! I've been using Monoprice's HDMI cables for a number opf years and so have many, many others and they work great. You can clearly see all the cables specs at Monoprice. Try to get that from Monster, no way! Monoprice is also an AVS sponsor:)

Here's the clearly listed specs for the v.1.3a HDMI from Monoprice:
FYI: Monprices HDMI cable spec'd below is 340Mhz, which equals 10.2 Gbps and the price is $12. Monster's 700 line HDMI is only rated 4.95 Gbps and their 1000 line is rated at 10.2 Gbps. What's the Monster price for a 6 ft 700 or 1000?

I currently have a Samsung HL-T6189S,
http://i12.photobucket.com/albums/a218/Jammasterc/IMG_2168.jpg
that looks so nice all in black.

My set is due to be replaced by Samsung warranty with the HL61A750A.

Why Samsung ever decided to put that silver strip below the 750A screen, I don't know.
At night, with all lights out, the 6189 almost disappears into the dark.

Maybe the silver piece can be taken off and spray painted flat black?

I just came from a HLT-6187s that had a broken screen when shipped to me, straight to the HL61A750. A couple things I want to say: I can tell you the 40% brighter is definitely not 40% brighter than last year's LED set (this is not neccesarily a complaint from me, I just want to clear that up). The "hotspot" that CNET complains about in their review of 2007 model (and to my knowledge, hotspots exist in almost ALL rptv's it just matters how pronounced it is (I had a hotspot on my previous DLP set too which was pretty bad honestly)) is cleaned up a little bit in my opinion. In the settings on this tv there is a setting that is something like "LED adjust". I have found that if I have that on "auto" it seems to have an effect on what I consider the "hotspot". The silver line on the bottom does not bug me so much. Last night I watched a movie at night, turned off the blue power light, and was amazed at how the the tv cabinet just kind of faded away. I never really thought about something like that, always thinking "who really cares that much about how the casing of the tv looks" but now I see why people consider this.

overall thoughts:
After messing around with some settings and watching "House of 1000 Corpses" on bluray through the ps3, I can say that so far I am EXTREMELY happy with this set. I chose that movie because it has such vivid colors, I wanted to see if they bled into each other and how much of a 3 dimensional look I can get. The answer is that it looks AWESOME, no color bleeding and a very 3 dimensional look. Really awesome contrast and black levels too, the black really did blend in with the black of the tv casing (or at least got very close) and I cannot imagine blacks truly needing to go much deeper (although I know those folks at Pioneer with their KURO line of plasmas are hard at work at it lol)

current settings:
I don't have these in front of me, so they are not exact, but:
movie mode, warm 1, brightness 30-ish at night 50-ish at day, contrast 85, I don't think I adjusted the color settings very much (think I just moved it a little towards green), LED setting to AUTO, no dynamic contrast or black level adjustment, color range wide, avycc on (i think thats what its called, its the new color mode from hdmi 1.3), and all "image enhancers" off (edge, dnie, etc).

On the PS3 I activated 2 things, one was called "super white" and the other "hdmi black level" (once again, don't have these names exact as its not in front of me). I believe these are both dealing with the HDMI 1.3 stuff, and with them on it actually greys out some video settings on the TV (there is an HDMI black level there, and i think it forces u to turn on the avycc and color gamut to wide).

As I said earlier, this really looks awesome. I am probably going to see how Beowulf HDDVD looks tonight (that movie already had a very 3d look to it on my old set (hlr4666w) but I play them on the 360 addon and only have my 360 hooked up with component. Thus: no 1080p for me :-(. I will have it set to 1080i and see how good my tv does at deinterlacing (I don't know what the best ways are to test this though)

A couple requests: Does anyone know of more refined settings to use? I don't have a DVE disc or anything to really get it set up. Also, if someone knows a good way for me to see how well it is taking 1080i to 1080p, that would be great as I would like to justify just using my 360 addon for HD's instead of buying an HD standalone, or messing around with hooking up VGA (or maybe I should just do that?)

Do you find that the settings from your old HLT-6187s are very similar to the settings used for your new HL61A750?

alvindd:

To be honest with you, I only had the 6187 for about a week. It always had a crack through it and I never messed around with the settings as much as I wanted to. It was too depressing lol. The settings that I now use on the A750 are based on what people said to use with the 6187 though.

I currently have a Samsung HL-T6189S
My set is due to be replaced by Samsung warranty with the HL61A750A.

Alvindd, why are you replacing your 89S ? I've been looking around and the specs/opinions I have read are almost identical between the 89S and A750. The prices on the 89S are starting to fall so I was leaning that way, but if they are problematic I would rather go with the A750.

Thanks for any insight...

Are you saying that the HLxxA750A has this issue?

http://i12.photobucket.com/albums/a218/Jammasterc/v.jpgNo. The "searchlight" isn't based on the displayed image. Rather I believe it's simply the result of the light engine being aimed at the screen.

On a solid light gray image you will see the area shown above slightly brighter than the rest of the screen (if you are looking down at the screen). Again from normal viewing angles I can't even see it on a solid gray image or with normal material.

My flecks are gone. The service man came today and the first thing he did was tap on the screen where the largest one was and it fell to the bottom of the set. :) He did however take off the access panels and removed the rest of them with a lint-free cloth.

To show him the flecks I used the gray test pattern and he said he wouldn't ask how I knew about the service menu. :)

Service guy wants to replace the LED engine(see picture above) and also has a loud buzzing noise, but Samsung would rather replace tv since it's 4 months old.

HLT-6189 is a great tv.
A750 seems to be slightly upgraded version of 6189.

FYI: Monprices HDMI cable spec'd below is 340Mhz, which equals 10.2 Gbps and the price is $12. Monster's 700 line HDMI is only rated 4.95 Gbps and their 1000 line is rated at 10.2 Gbps. What's the Monster price for a 6 ft 700 or 1000?Heh, J&R sells the 6ft 1000 for $130 and the 6ft 700 for $80!

As Erock1 and others have stated Monoprice cables are top quality and a great deal. Never had a bad cable from them myself.

Wow, I'm not an expert with Calman at all, but those results look pretty dang good. The color temp/gamma tracking looks pretty good, as do the colors. Looks like you might be able to bring the lower end of the IRE a bit closer to D65, but not too bad so far. How much tweaking did you have to do to get this? Was it in the service menu, or was this all with adjustments from the user menus?

It seems like these newer TV's give you quite a bit more adjustments than in my older DLP. I had to to everything in the service menu to adjust the RGB gains and offsets. I have no experience with the newer controls, but hopefully they have made life a lot easier since my HLN617W generation. If you were in the service menu, did you mess with turning the color management system off before adjusting colors?

When you are done, please post (or PM me) your settings!

For those interested the following 3 pages show the result after a minimal amount of calibration. Calman V2.1 & I1 Pro

It's time for me to come to the well and ask a question of the talented folks here:)

I have the 61A750 (got the model number correct this time) and was making a few basic picture adjustments when I noticed that in the Picture Options menu, my adjustments for: DNIe, HDMI Black Level, Film Mode, and 3D Effect are all greyed out & not accessible.

My only connection my AVR to the A750 is via HDMI on the A750's HDMI input #1. I've tried all picture modes, standard, dynamic, movie, all without a change. I also tried changing the "Entertainment" modes. No change, all the above till greyed out.

Does anyone know how to make these settings accessible? After a few weeks of break-in time, I wasnt to use my HD-DVE disc to calibrate and want these settings available.

TIA,
Eric

First I looked under Big Screen TVs.
And then I did a search on all of the following...

HL61a750
HL-61a750

I've continually noticed in every store that the hl61a650 diplays a brighter, sharper picture than the hla61750. Is this just how there set up or is led technology just not quite there yet as compared to bulb. I also noticed the 8187's led is rated at 20,000 hours vs. the 750's 60,000. It leads me to believe that their using the dc4 but maybe using a lower light emitting led to lengthen the life. I don't know how accurate this is but my best buy listed the dynamic contrast ratio of the 650 at 50,000 to 1. the 750 is 10,000 to 1.
Does anyone have any real world experience with both of these. It's so hard to tell at the store.

I think that the LED's just aren't as bright. I do notice having to have my A750 a little brighter than my oldschool 46 inch DLP. But we are talking a difference of 30ish on old one to 50ish on new one. And after I discovered this "auto LED adjust" setting it is considerably brighter (and I also think there is not as much of a hotspot with this setting).

So yes, maybe the LED's arent as bright, but that does not outweigh the benefits of 1)no color wheel, 2)no rainbow effect (nearly), 3)instant power-on, 4)quietter running, 5)tremendously better life and no bulb replacing.

I do not have a link to give you, so I apologize for that. This tv CAN do 120hz... but it is for the 3d or the dualview modes, and possibly for reproducing 24p content. I do not believe that under normal use it runs at 120hz. The main reason why LCD's tote the 120hz feature is because they need it to fight off motion bluring and juttery movement... neither of which are a problem with DLP's because of how the technology works. In other words, on a DLP set I do not believe there is an advantage to 120hz except for potential 3d effects and for better displaying 24p content (which I think this tv does both)

Just a head's up to potential buyers. I live in the Chicago area, and have ALWAYS bought my electronics and appliances from Abt. I can't vouch for their internet service, but their local service and prices are the standards by which others in the industry are judged. You want THE best prices? Call Abt.com or their local (847) number and ask to speak directly to a sales drone. Make up a reasonably good price, THEN ask the salesperson to beat it. If the set lists for $2400, I'd tell them I could get it for $2100 including tax (local 9%) and delivery out the door. 9/10 times they will beat it. And if THAT drone won't, hang up, call back, and ask for another one. I guarantee you that THAT person will. I've used the same two drones for the past 10 years and they've always beaten the tar out of competitors. If you don't ask, you won't get, but trust me....if you're actually ready to buy (and not just waste time), they'll respond. Really.

And btw, the place is HUUUUGE. They're the largest independent, family owned business in the country, and they have at least 25 sales people on the floor at any one time. On the weekends, it's probably closer to 50. So if you need to speak to a new salesman, you'll usually get a different one when you call back. And don't forget the name of that person if they cut you a great deal. They'll cut you an even better deal next time. :)

wavepelt:
I am not positive if it uses the 120hz for that or not. But I did watch somethin in 24p last night, and it does look smoother than normal... so if it's smoother but does NOT use 120hz, how would it do it? I am under the understanding that anything other than 120 hz or flat out 24hz would require pulldown hence not being smooth.

04-03-08, 03:51 PM

Does anyone else know or agree with this? I might choose them over highdefinitionstore.com if they can match the price....

I've never done business with the highdefintionstore, but I've not heard a lot of complaints. I would however be willing to place a bet that I could get Abt to beat their price. The key is knowing the true MSRP, and the commonly discounted competitor's prices. Fortunately, I'm at the point now where I don't have to know either with my sales drones. I simply tell them I'm ready to buy, and to give me their best price. NEVER has that price been even close to the competition. I almost bought the HLT6189S a year ago when it first came out. If I recall correctly, it listed for around $2700, yes? My guy was willing to do $2100 out the door...even way back then.

I have no idea what they mean by "120hz." There's no way this set is refreshing at 120hz like the last 60" Sony KDS RPTV. That thing looks amazing at 120hz, I love it. I just don't like that it's bulb and the cabinet is ugly. Not going to be 67" either.

But yea, I do not believe in any way these Sammys are actually 120hz.

maybe some people cannot see the difference. Again, when I myself saw the Sony, I was amazed because the difference in refresh or motion was like night and day compared to the other TVs around. Some gamers argue that the differnce between 30 and 60 fps is negligible, but I can see the difference there also like night and day, so I must be one of the lucky people to perceive higher frame rates and refresh rates.

But I also can barely taste the difference between cheap and expensive wines, and am convinced the people who drink wine as a hobby are making themselves believe there are hints of fruits, chocolate, spices, etc in those wines. I cannot taste a hint of ANY of these. haha

Erock: When using HDMI (my ps3) these were all greyed out except HDMI Black Level, and Film Mode. Then when I set my ps3 to "deep hdmi blacks" or whatever they called it, and 24p; those options got greyed out also. I think it has to do with what the component you are using is forcing it to. For instance, I wanted to turn film mode OFF (as I think it controls the 3:2 pulldown (or whatever ratio it is now) because with 24p you do not want the pulldown to occur. After switching the ps3 to 24p, it went to off and greyed it out.

On other sources I believe these settings are available, I have messed around with settings on my cable box (component inputs) and I believe they were all available.

finsmaniac,
I think you're right about this. I believe the ability to access certain picture controls is dependant on what source or component is connected to the 61A750. Presently all my components are connected to my receiver and from my receiver to the A750 via HDMI. When I have a chance I will connect my HD-DVD player directly to the A750 via HDMI and see if any of the controls becomes available.

Now that you say it that way, that does kind of suck. At the present time, my reciever is not good enough to run everything through, but that is (and should be) everyones end goal, to get a capable reciever and do this. If the tv does not grant access to all features this way... that is a big inconvenience.

Try renaming the input to something> I dunno what, I just know that people say if you rename an input to PC it grants other features

i'll be getting delivery of mine next week... the 61A750. unfortunately, i won't get 1080p out of it, because my dish VIP622 HD receiver's signal is only 1080i. I emailed Dish and they confirmed the hdmi on all their boxes is 1.1.

That may account for not being able to change some of the settings.

A brief read of the manual states something like hdmi 1.3 to prior hdmi versions can cause some flickering. We'll give it a try and if we don't like it we'll go with component.

if i can't get 1080p from dish, what does it matter right?

the set is future proof - we'll just have to wait for the future to catch up with it.

edit to add, the OTA antenna thru the samsung will probably give me the clearest picture, if local broadcasts have 1080p broadcasts.

04-03-08, 06:55 PM

From the information I received here this set does in fact refresh (or display) @ 120hz (120 frames per second)

I believe what your referring to is Sony's motion enhancer technology, which creates artificial frames in between source frames in order to reduce judder / smooth the picture.

This person commented on Amazon...don't know accuracy or source....but here it is for whatever its worth:
---------------------------------
Eric Collins says:
Just to be clear, *this* set ( HL61A750A ) uses TI's Dark Chip 3, and TI has announced Dark Chip 4 with 100,000:1 contrast ratio. Samsung has not announced any plans around Dark Chip 4, but at least one 'eye witness' web report was in TI's booth, looking at Dark Chip 4 and it was a Samsung display with electrical tape failing to cover the Samsung name. (side note: Is Janet Jackson working at Samsung?) Regardless, for the price, this is a great set, and only about 12" deep, vs. the 4" or 5" of a LCD or Plasma.
-------------------------------------------------------------
The "motion enhancer technology" just sounds like 3:2 pulldown which is what they do have when there is still a lack of smoothness. We need a complete expert answer on 120HZ. We deserve it now since the CES 08 pics had a 240 HZ prototype.

Also runs cooler and uses less power.

Unless you just gotta have torch mode, or do a lot of viewing in a very bright room, I really don't think a little less brightness is any kind of a big deal.

There are many more important metrics for image quality, and the attributes you mentioned are real plusses as far as I'm concerned.

HL61A750.

Yes, had a second one tonight.

Both times while watching Blu-Ray movies (via PS3 @ 2.20 firmware) connected to HDMI input 2. 1920 x 1080 @ 24 Hz.

This second go around I reversed back on the disc and played the scene that the reset occurred on. Of course, it played fine the second time thru.

Cable viewing (thru HDMI input 1) has been fine so far.

I haven't tried switching HDMI inputs yet, or reverting back to component, primarily because I shouldn't have to.

I did just call Samsung support afterwards and after a few minutes on the phone I realized I wasn't going to get anywhere. "If the Blu-Ray player is not a Samsung there's no guarantee it will work with our TV's. We even have problems with some of our Blu-Ray players not working." Wow. I didn't feel like arguing tonight, so I got off the line without further discussion.

Other than the occasional reset via the Blu-Ray player, I love the set. I'm just hoping this will be fixed via a firmware update to one of the devices sooner rather than later.

wavepelt

04-03-08, 09:33 PM

It doesn't matter what the refresh rate is. It could be 120,000hz. All current signals are either 60hz or 24hz (24p). A 120hz refresh will just show the same image twice. There is no more content to display. What Sony does is digitally create frames in between the actual content frames. Those are black frames in many cases, but can also be generated frames that are intermediaries between the two content frames. Doing this does provide a more visually pleasing motion, but it also creates artifacts. Go to some of the videophile pages and you will hear numerous instructions to turn the Smoothvision (or whatever Sony calls it) off. If you watch for a little bit longer than 5 minutes you will start seeing the artifacts and it will start to annoy you.
There is only one legitimate reason to have that refresh rate, 24p, so you can do 5:5 instead of 3:2 pulldown. So, with the exception of digital gimmickry (3d, dual-image on one screen, and Smoothvision) there is no reason to have a higher refresh rate than 60hz until your content provides more. Right now, that would be none of them.

If I go by what you said, then the "digital gimmickry (3d, dual-image on one screen, and Smoothvision)" are the only 24p sources known.
This article, which helped convince me to be sure of this spec, seems to contradict that.-

120Hz: The Sweetheart Of The Industry

Don't let yourself be distracted by the doodads offered in place of real progress. I shouldn't be saying this -- I am in advertising after all -- but the odds are you don't need a 108-inch flat panel TV on your 120-inch living room wall. What you do need, whether you realize it or not, is an HDTV with 120Hz image processing for quicker frame rate conversion and blazing fast pixel response times.

Unconvinced? Here's the facts: Film is shot at 24 frames per second. And just about every movie disc you can buy is encoded at that speed. DVD, HD DVD, Blu-ray - all 24 frames per second. Trouble is, television programming runs at 30 frames per second and most TVs conform to that standard. See the problem? Fitting that 24-frame content onto a 30-frame screen isn't a seamless process. You can't divide 24 by 30 evenly -- so video engineers fill in the gaps. Known as 3:2 pulldown, this conversion process spreads out 24 frames into 30 by placing one frame on the screen three times and the next one after that two times, and repeating this pattern again and again and again? which sometimes causes the stutter and other visual artifacts that can ruin the illusion of losing yourself in a great movie. To further complicate things, some video content is recorded at 60 fps, such as certain modern special effects and computer animations (think Matrix), which tricks the 3:2 pulldown process and trips up transmission of the intended on-screen image.

24, 30, 60? Are you beginning to see the beauty of 120Hz? Grade school math tells you that 120 is a multiple of 24 and 30 and 60. 120Hz image processing shows 120 frames per second, allowing these TVs to reproduce unconverted, evenly extrapolated 24 fps movie, 30 fps television, and 60 fps special effects programming, without the stutter and other clutter of 3:2 pulldown. To return to the top, a bigger TV is not necessarily a better TV. Without 120Hz image processing, some things will certainly be bigger, but they'll still be just as blurry -- especially on-screen text. Imagine missing the get-away car's license plate number when watching a murder mystery or not catching the content of those top-secret government documents in a super suspenseful spy flick. Maybe it's as simple as not being able to read the jersey of the player who made the interception during the big game. No matter what the instance, your TV's instant of indecision just cost you the crucial bit of information and lost you to the rewind once again. Don't bother with bigger. Go with better, faster, clearer. Go with 120Hz.

Guess what? Conveniently enough, the Mitsubishi Diamond 833 Series offers 120Hz. They call their version Smooth120Hz, which matters not at all. What matters is that it doubles the amount of frames from 60fps to 120fps and does it the right way by using real-time calculation of every single frame of video to create entire new frames of information. The results are spectacular. See for yourself. How? If you look in the upper right corner of your screen, you'll see a little grey "button" in a field of green. It reads "add to cart." I think you know the right thing to do.

Here you go HDMom. I took a few shots and thought this one provided what I think gives you the best overall view of the stand & 61A750.

As I said in my first post towards the beginning of this thread, using the 56" version allows the 61A750A's screen (only) to extend about 2-3" on each side of the TR500X3B and 61A750's attached stand itself sits on the TR500X3B with plenty of space on each side before the edge (actually, there is 5" of room on each side)

I know another member, Kevin Rohrer indicated that he thought the exact opposite of my findings. Again like everything else, these things are subjective to each person, just like who thinks the 61A750A's case is flimsy, it's individual perspective. As I said earlier, I find the stand solid, each piece, legs, back, top are solid and heavy. All screws & bolts are solid too. My stand doesn't have any side to side or back to back wobble. Even if I disregard the fact that I got the stand for FREE, I still think it is an attractive, solid TV stand. But FREE does help;)

Cheers,
Eric

Eric, thanks for the pics. I put the stand together last night as you suggested and it worked out great. I'm not worried about the set getting knocked over as someone else posted but then again I have it in a spot where that wouldn't happen anyway. I agree with what you said about the size of the stand - it's not as tiny as it looks in the pictures.

Now as for the set itself and build quality - the case is solid and the bezel doesn't move when I apply pressure or try to twist it. Definitely way better then the '07 sets I saw at BB.

The PQ is great! I was getting a bit worried reading this thread but my fears have been laid to rest. I was up late last night and haven't had a chance to calibrate it yet but I did watch TV for about 1/2 an hour. No bowing whatsoever, at least not that I could tell although I haven't gone into the test patterns yet. Blacks are deep and everything else just pops. Watched a few minutes of the opening scene of Star Wars Episode lll and I was floored! I expect that PQ will improve a bit after I do a proper calibration but I'm extremely pleased with it right out of the box. I'm sure my boys will give it a good break in this weekend so we'll see if we have a power down issue when they play games or we watch movies on the PS3.

Now we have conflicting reports..
Nobody was able to confirm with Samsung or open up the TV yet?

This person commented on Amazon...don't know accuracy or source....but here it is for whatever its worth:
---------------------------------
Eric Collins says:
Just to be clear, *this* set ( HL61A750A ) uses TI's Dark Chip 3, and TI has announced Dark Chip 4 with 100,000:1 contrast ratio. Samsung has not announced any plans around Dark Chip 4, but at least one 'eye witness' web report was in TI's booth, looking at Dark Chip 4 and it was a Samsung display with electrical tape failing to cover the Samsung name. (side note: Is Janet Jackson working at Samsung?) Regardless, for the price, this is a great set, and only about 12" deep, vs. the 4" or 5" of a LCD or Plasma.
-------------------------------------------------------------
The "motion enhancer technology" just sounds like 3:2 pulldown which is what they do have when there is still a lack of smoothness. We need a complete expert answer on 120HZ. We deserve it now since the CES 08 pics had a 240 HZ prototype.

Would anyone care to share their settings?

I was really surprised today. I got my hdmi cables from monoprice and hooked up my hd-dvd player with them instead of the component cables I was using. The movie itself(Dazed and Confused) I didn't notice any huge difference between the 1080i of component and the 1080p/24, but on the universal opening I noticed a huge difference.

One question I have though is; How can you tell if a movie was shot in 24fps or the normal 29.97fps? The Toshiba hd-dvd users manual said that if playback seemed jittery you should set the player to 1080p instead of 1080p/24 but was wondering if there's any clear way to know outside of noticing some jitter.

If the movie was filmed, it was shot at 24fps. When it is put on DVD or BD it should still be at 24frames and typical players will do 3:2 pulldown. That kind of give 24 frames, but not really. If your display accepts a 24p signal and has a refresh that is a multiple of 24 (like 120hz) it will do 5:5 and essentially each individual frame will be displayed over 5 cycles before changing. That is as close to having a film projector in your house as you will get. Your Samsung does 120hz so it will accurately display a 24p signal and it should even identify that source as 24p.

Just a head's up to potential buyers. I live in the Chicago area, and have ALWAYS bought my electronics and appliances from Abt. I can't vouch for their internet service, but their local service and prices are the standards by which others in the industry are judged. You want THE best prices? Call Abt.com or their local (847) number and ask to speak directly to a sales drone. Make up a reasonably good price, THEN ask the salesperson to beat it. If the set lists for $2400, I'd tell them I could get it for $2100 including tax (local 9%) and delivery out the door. 9/10 times they will beat it. And if THAT drone won't, hang up, call back, and ask for another one. I guarantee you that THAT person will. I've used the same two drones for the past 10 years and they've always beaten the tar out of competitors. If you don't ask, you won't get, but trust me....if you're actually ready to buy (and not just waste time), they'll respond. Really.

Abt also sold original DirecTV HD Tivo boxes on ebay at inflated prices when they had pre-orders in their system just sitting there gathering dust. I'm just sayin'.

Is anyone still experiencing resets??

I had another reset yesterday using my Xbox via component directly to the tv. It was annoying having the TV reset in the middle of a COD4 match.

I called Samsung and they faxed a service request to a local repair company. Problem is I don't want to let a repair company take it from my house for a repair. When they took my HLR6168, they had it for three weeks. They repaired the shadow problem but left a tiny smudge on one of the mirrors, which shows up as a small blob on the screen. If they don't repair it in home, I my just return it to CC and avoid Samsung from now on. No idea what to buy next since I like the picture and the lack of a bulb.

Their 2008 LCDs on the LNxxA650 forum also have the reset problem. There doesn't appear to be a fix yet. Someone mentioned burn marks on a circuit board. Others have mentioned a new firmware and having the power supply replaced, both didn't work for them. Which makes me think the repair company will have no idea what to fix on my TV. I don't want to be stuck with a tv that resets randomly or that may fail from the problem after the warrant expires.

I don't know. I'm was just going by what best buy said for contrast ratio. All I know is the 650 was right beside the 750 and the 650 looked alot better. obviously the real test is at your own house with the proper hookups. Things always look better at home.

Im thinking aboutgetting this tv 61" led model, main thing im concerned is bowing issue because I watch alot of sports should I be concerned ?

also wonder how PS3 and xbox360 will look also Big on Sports.

I think its pretty obvious if you read the last 10 days of posts or so you should be concerned--that its a crap shoot if you get a set with bowing or not ;) How to alleviate that concern? Purchase from somewhere you can get your set swapped if you get bowing or other issues you don't want to put up with. If the TV meets your buying criteria, why let a potential defect stop you.

I have noticed just a tad of bowing and what seems like it may be a slanting issue. When I was looking for problems, that is. I noticed on 4:3 broadcast (with the bars) right at the VERY bottom, there is a little bowing out. I also noticed when you have bars across top and bottom (2.35:1) the bottom right is slightly higher than the bottom left. I measured these and we are talking 1 or 2 millimeters. I decided this is not enough for me to want to deal with an exchange thru the mail. I watched the NIT championship game last night (go bucks!) and it looked great and I could not notice either of these problems. I believe someone said the espn ticker could be smiling at you if you have severe bowing and that would be HORRIBLE, but i notice no such thing. Like turls said before, don't let it stop you from getting one. if its THAT horrible I am sure you can return it, but I would probably assume most people have my case and it really is not noticable with normal viewing

Yesterday I was raving about setting the LED adjust to "auto" . After getting home yesterday, I turned on the TV and I felt like my eyes were going to be burned out on that setting. I dunno if my eyes were more sensitive or what, but I dropped it down to "medium". I dunno if this will change for my ps3 viewing also or not. So far:

for tv (cable box thru component input):
standard mode, colors all standard, no black adjust, no dynamic contrast, LED adjust "medium", contrast 83, brightness 30ish in dark 40ish in light

for ps3/bluray (hdmi):
movie mode, color bar a little towards green (only a few, like 47/53 or so), contrast 80, bightness 30ish in dark 40/50ish in light, LED adjust "auto" (this may change when I revisit it) no dynamic contrast or any other "enhancements", film mode OFF (this gets greyed out once you set the ps3 to 24p anyways)

I would like a more professional calibration though... I do not have any DVE disc or anything. I am probably going to put in a THX dvd and do their setup tonight (more than likely star wars ep 3) and see how much that changes things

I had another reset yesterday using my Xbox via component directly to the tv. It was annoying having the TV reset in the middle of a COD4 match.

I switched my PS3 to component and have not had a reset since. I have not yet watched a movie with this setup. I'm having a party tonight and PS3 will be playing for several hours so I will know if reset is an issue with component.

As a side note... setup component for all resolutions, test worked fine for each then I played a game @ 720. After quitting the game the PS3 returned to the main menu and the screen cycled through varoius resolutions and concluded: "Mode Not Supported". Nothing would display long enough for me to adjust the settings so I had to switch back to HDMI then reconfigure my component output. This time I left off 1080p and it has been working fine since. Not too big of a deal since the only thing I have that will run at 1080p over component is the PS3 menu.

My PS3 is running the latest version (2.20, I think. Updated a couple weeks ago). The PS3 80Gb was bought from a Sony Store at the end of Dec. so it should have new/newest hardware specs.

I will keep playing around with this because I really want to use PS3 over HDMI. I may go buy a Sony BD player to see if I have any issues with it then return it when my tests are complete.

Praying for a PS3 or A750 patch to make my life complete...

I also noticed when you have bars across top and bottom (2.35:1) the bottom right is slightly higher than the bottom left. I measured these and we are talking 1 or 2 millimeters.

I got my TV wednesday and also noticed the exact same kind of "slanting", bottom left sits a bit lower than the bottom right, but the top seems to be ok. I tried manually "flexing" the cabinet to fix it (and it did if I stood there and held onto it forever) but it wouldn't take and as soon as I let go it goes back to how it was.

The actual slanting I would say is anywhere from 1/8" to 1/4", probably closer to 1/4". If I "lose myself" in whatever I'm watching I can usually not notice it, but if there are black bars or if I throw up a menu on screen, I can notice it pretty easily if I go looking for it. My better half doesn't seem to notice or care and thinks the set looks great :p

As much as it bothers me that it is there, it's not enough to go through the hassle of exchange, at least not yet. Thankfully it's not as severe as some others have reported with this or previous models. As for other issues, I've had it reset on me once, the day I got it, and it hasn't since. I've mostly been using the PS3 through it, watched the free Spiderman 3 Blu-Ray it came with at 24p with no issue, and have played untold hours of NHL '08 and the PS3 hiccuped more than the TV did. I had the PS3 hooked up through component until UPS showed up with my monoprice HDMI cables and it was able to do 1080P no sweat (PS3 menu and in game). Come to think of it, that was probably when the one reset happened, no more since swapping to HDMI.

All things considered, I am happy with it :D

The internet and ebay are a whole different animal than dealing with a live, accountable salesperson. I'm just sayin'. :)

Btw, I'm also into cycling. You wouldn't believe the number of threads about buying from bikesdirect.com vs. from a local dealer. The bottom line is pretty much that if you're a good mechanic and know your sizing, take a shot and buy from the internet. Same goes for the TV. If you're a tech, or don't mind the hassle of trying to return an internet item, take a shot. Otherwise, I recommend a local dealer. Tax sucks though.

If I sound like I'm shilling for Abt, I apologize. I just thought I'd let folks know that there ARE some really good deals out there, and from reputable sources...in MY humble opinion. ;)

yeah, I don't notice a slant for the whole picture either... it just seems to be the bottom. I still have yet to throw up a grid to see how bad it effects everything, I will have to do that. All in all though, I would like to add that I am happy with it too... :cool: sometimes I feel like I need to repeatedly state that with the negatives on this thread lol

Also, I have not experienced any shutdown yet (hdmi for ps3, component for cable). But I have not done anything for more than like 3 hours straight so far.

Bowing update on my 61" 750: the bottom "frown" is definitely more pronounced than the top "smile". Using sports tickers to measure, I see a 1/8th inch sag in both bottom corners. The top bowing is smaller than that.

A few questions:
1) As I am a newcomer to HD, I've always been used to the espn SD tickers being flush to the bottom of the screen. On this set (and on my new Panasonic 42PZ85 plasma), the espn HD tickers are not flush to the bottom. They are raised, with additional screen below them. Is this how they are, or do I have some wrong setting? If they are meant to be raised like that, I don't expect the 1/8th inch bowing to be noticeable.

2) When I watch a non-HD program in non-stretched setting, are the black bars on both sides supposed to be perfectly straight? My border lines slant outwards at the top and bottom, and it's quite noticeable. Is this a symptom of bowing?

Not sure if you are asking me directly, but I doubt the potential for bowing affects any model more or less than the other since my all my 1st gen 50" DLPs had the issue (I went through 2 or 3 of them, not all because of bowing, but they all had various degrees of bowing).

Sweet!

Yes, please explain "a minimal amount of calibration" and let us know whether this was through CCA (or something else) in the service menu, or via user adjustments.

Grayscale was done in the service menu using the movie mode. After entering service menu and returning to normal all items in the user menu return to default settings and must be reset. Using Getgray calibration disk brightness adjusts as recommended, contrast like a lot of digital sets would not limit to 100%, left setting at 90. Color temperature set to warm 2, sharpness 0, gamma from -3 to 0, LED control to auto (made big difference in brightness), all other video enhancements to off. xvYCC on really messes up color gamut. color set to 49 from 50, tint left at 50/50. Without service manual I didn't attempt any other adjustments in service menu where I suspect you might be able to change the default settings. As far as blacks are concerned I can see lapels outlines on black suits where I couldn't on the old Toshiba (2004 model) which was calibrated. Skin tone depending on source is good to excellent. None of the problems others have had with screen distortion (just lucky?). Looks like a big screen high priced panel TV.

Has anyone with the screen slant had a Samsung tech out to adjust that? This is not the same as bowing. I believe the slant on one side can be adjusted.

So, if I find a good price on the internet, you're saying ABT will match it?

How painful would it be to try?

If a competitor's price (including fine print) is legit, I'm sure they'll match it.

You live in the Chicago area, yes? It's a no brainer. And if there's a problem with the set, they'll swap it out. Delivery's always free. Sorry Turls. ;)

From all the posts I've read in this thread, it seems like everyone that has a PS3 with "reset" issuers has it connected "directly" to their A750 when this connection is with HDMI.

Doesn't anyone have their PS3 connected to their A/V receiver and then to the the A750 via HDMI? If you do, are you experiencing any reset problems?

The reason I'm asking is I'm thinking about getting a PS3 for games (daughter)and Blu-Ray DVD viewing (me) as I already have an HD-DVD player. I was hoping to try to figure out if the PS3 connected directly to the A750 with HDMI is the problem or not.

TIA,

I had another reset yesterday using my Xbox via component directly to the tv. It was annoying having the TV reset in the middle of a COD4 match.

Just curious, were your running at 1080p resolution?

I switched my PS3 to component and have not had a reset since. I have not yet watched a movie with this setup. I'm having a party tonight and PS3 will be playing for several hours so I will know if reset is an issue with component.

My next step was to try the PS3 @ 1080i by removing that option from the PS3 menu. If that didn't work, I was going to try the component cables. The only problem is that in approx. seven hours of Blu-Ray viewing, the reset has only happened twice. Just means I would have to sit around watching Blu-Ray movies. Wait, maybe that isn't a problem!

I changed the PS3's 24p output from automatic to always. Since then I've watched though No Country For Old Men without a reset.

Still havent had a reset while using the 360 or DirectTV box.

Interesting, erdamon. I'll try that (No Country For Old Men did force a reset the first time through - Spiderman 3 being the other disc).

On a side note, in the Official Samsung LNxxA650 Owner's Thread, users mention that Samsung has released a firmware update to those sets.

The description reads:
This firmware will correct intermittent power off and on occurrences some units via [sic] USB memory drive.

Unfortunately, I have an older receiver which does not have HDMI switching capability.

I'm curious, though, if it isn't related to resolution (e.g., 1080p) rather than connection method (HDMI vs. Component)? Just a thought...

That's nice to know, thanks for the information. I checked some url forget which one and saw that professional calibration seems to run $300-600 for that price I could get a ps3 and a few movies. I like my HD but I'm not made of $$$.

Need quick help.....I just brought my 61A750 home! Am pumped to get it hooked up! My question is this. I bought a monster surge protector HTS800 and it is rated for 1850 joules but the guy at CC said it wont protect the TV as it has to be at least 2700 joules. Does anyone know if this is true or is it fine to use the one I bought??? Thanks!

Don't listen to them. They got you on the hook with a Monstercable surge protector and they want to reel you in on a $400 Monster conditioner. Many surge protectors are just a cheap breaker and a nearly impossible to collect on insurance policy. Your home-owners insurance / renters insurance may even provide that same coverage. To make matters more confusing, many equipment manufactures are telling people not to plug their product into a surge protector. I think the new Xbox was one of the first to request no protection.

That's what I thought.....but definitely did not buy it there, ordered it online for 60 bones so I am fine with that.....but thank you, I feel better and am about to hook it all up right now! If anyone want me to do anything with the tv, just send me a message and I will try to help........

I received delivery of the 61A750 today. Purchased from Best Buy - you can find an online 10% off certificate (google it) - so I got a good deal.

I have an HD cable box and am running HDMI to the new 61A750. I set the cable box to work with formats 1080i, 720p, 480p and 480 wide.

The problem I have is when I watch stations that are non-HD (ie, sports channels), they are blurred and grainy. The HD stations are crystal clear, however, the non-HD are not a good picture. I called Samsung - who was no help (they blame it on CableVision - as they say if I have a clear picture on HD, that means the set is fine).

Any help?

04-04-08, 11:01 PM

Ok, you have to actually edit the name of the HDMI3 source to get all the features available to you to use either 1:1 pixel mapping or the "PC" mode where you can resize the image so you get your whole HTPC desktop on the screen without overscan.

-Press Source
-Move to HDMI3/DVI
-Press Tools
-Choose Edit Name
-Choose "PC" as the choice

This allows you to then use the 3 PC modes for Picture Size (P.Size): Wide PC (which allows all the adjustments), Wide TV (1:1 Pixel Mapping as far as I can tell-noticable crisper text), and 4:3.

Thanks so much for that info, I believe the Wide TV isn't 1:1 pixel mapping but it does appear a lot closer and clearer as you indicated. I can adjust the Wide PC to get it to not have any overscan.

Anyone have any settings? I saw some back from one person's preference.

I do have some dust specks in the top left of the screen but it's literally like 1 pixel and I'm not going to go through the trouble to try to get rid of them since I only see them when inspecting the screen with my nose against it.

I don't notice any bowing and I'm not sure if I want to check for it or else it might become apparent in anything I do.

120hz doesn't seem to be like the 120hz on the Sony and Samsung LCDs I saw today. Made film look like video... which I thought was very awkward and not pleasing to the eye at all. Like watching soap operas or something...... but I'd like to try it out anyways at home. Any ideas? I have the HTPC so I tried to select 24hz or 30hz but noticed no difference between those and the 60hz selection....

I just got the TV setup and the picture is phenomenal. However, I have been unable to play any DVDs thru the HDMI cable. I have tried two different Blu-Ray players (Sony BDP-S1 and a brand new Samsung 1400); neither would play. The TV recognized both players in Setup, and even recognized the 1400 as an Anynet+ capable device. But it wouldn't access either unit from either HDMI1, 2 or 3, with it displaying an error message stating that the device was not connected, even though they were both listed as being available Devices. I have also used two different HDMI cables with them (Rocketfish and AR). The 1400 worked fine using Component. The satellite box connected with HDMI works fine.

Interestingly enough, the 1400 doesn't auto recognize HDMI even though the manual says it will. And the TV won't let me select the HDMI port the 1400 is attached to.

One clue in the 1400's manual states that the HDMI cable must be HDMI-CEC capable, but I have no way of knowing if that is problem or not. Would any HDMI cable work, or do I need one that is specifically made for HDMI1.3?

Why doesn't the 750 access either player? The manual states that some cables wouldn't work, but didn't suggest any that would. Help!

Kevin, that's goofy you can't get either BluRay to work. Not sure what to offer on that one.

On my continuing saga, CC showed up to replace the set today (because of focus and bowing issues). I had asked them to bring 2 sets in case the 2nd one had issues as well. Not sure if they brought 2 or not because the 2nd one is a keeper, unless new issues pop up that weren't apparent using the service menu grids and a night of viewing. . .focus is so noticably better on this one (and uniform across the picture), especially on a HTPC running the regular Windows desktop. Still have a little smiley at the bottom, but it is more uniform across the set and is probably at the worst spot about half of what the first set was. I have one spec of dust on the screen in the bottom right hand corner but like Smidget I can't see it from viewing distance and don't care about it now. . .for now I'm a happy camper. . .

OK one more question/problem. It seems as though the 360 is the only source that looks to have a "convergence" problem for a lack of better words. It's like there's a Halo (HA!) around all the text if that makes sense. Any ideas? Hooked through Component 1 or 2 I forgot....

Smidget, please do this for me.

Does lettering, menus etc have "light smear" or "halo" around the edges of the letters............particularly around the edges of the screen - corners etc. Can you actually see the "light path" beaming the letters to the screen - sort of like a movie theater with a little smoke, seeing the light path from the projector all the way to the screen. Light smear in the edges (and some halo) is the result of cabinets to thin. Does your set have that?

Convergence - Get something with letters all over the screen (white letters on black or visa versa). Turn the color down to ZERO. Do any of the letters or edges anywhere on the screen have red, blue, or green edges to them? If you have colored edges anywhere on a 100% B&W picture, that is a convergence problem. Assuming the new Samsungs have "3" LEDs to project the image and you have convergence errors; then I assume it can not be adjusted out. To save cost, Samsung made for "no" adjustment of the 3 LED system they used last year; so I guess that is the same this year?

To answer the first question: it seems to be everywhere more then corners. But the 360 is the only input (at 1080p or 720p) that I've been able to tell so far to exhibit this. The Wii (only 480p) does not show this problem on the "WARNING" screen with white letters and black background.

Second question: I did that with the Wii @ 480p which is in a separate component slot it and does not exhibit these problems. I actually received a new 360 with an HDMI slot and tried to plug that in and the issue is not there with the haloing. I plugged the 360 in the same component slow as the unaffected Wii is in and the same issue.

That makes me think it's the cables or somewhere and not the TV which makes me quite happy. I'll just use the HDMI out for the 360 now ;)

Component cables can create the problems you're describing if the propagation times or lengths are different between the three signals.

I just got my 546A650 today and am watching a baseball game in HD...I went with a Rocketfish HDMI from my Comcast HD box, and when I am watching the game I notice some "pulsing" and blurring in the image when the shot is of smaller objects, like a shot from center field of the batter at home plate, or the crowd. I then switched back to the component cables I had from my the Sony 42" RP the Sammy replaced, and the pulsing and blurring are better. I also noticed some white pixiliation on darker colors with the HDMI that seem to have diminished with the component cables. However, the HDMI did give a clearer picture on close up shots.

So, the verdict is still out on my new, and first, Samsung TV...

One last concern...I am having problems programming my Harmony 670 remote - I can't get it to seamlessly switch sources when I want to go from TV viewing to DVD viewing...

I think I can help understand the harmony thing. I have a harmony 880 and I have had a samsung DLP for years (720p 46inch before this). The problem that I had was that the samsung remote has you cycle through inputs, and not directly select them. Couple that with the fact that when an HDMI device was not on, it wouldn't actually cycle through that input because it could tell that it wasn't on. This causes a big problem with the harmony knowing how many inputs to cycle through.

I called logitech and tried explaining this, and told them that I don't neccesarily think that it is broken or anything, thats just how the harmony remote works. Well the guy I talked to seemed pretty useless and I dunno if he understood what I was saying. After wasting like 2 hours with him, I told him I had to go and couldn't mess with it anymore, and he said he was going to pass it on to a higher tech and they might email me back with any findings. Two days later I got an email with a custom program that actually had commands that took you directly to certain inputs! And it all works great now.:) I still use this same custom program for my new TV (this 61a750).

I hope this helps with your understanding, and I would call logitech and see if they could do the same for you

WOW, sounds like the A650/A750 was released before Samsung fully tested it.

Random 'power offs' during viewing and Blu-ray players not recognized are major issues.

I hope that it could just be the version of HDMI cable in use for the Blu-ray player issue, tv may require HDMI v3 HDCP capable cables.

Read some of these cable specs. https://www.cablesforless.com/index.asp?PageAction=VIEWPROD&ProdID=15614

Could the power off issue also be related to the type of HDMI cable in use , say a "handshake issue" ?

I think it truly is the source material. I have Comcast and a lot of my SD programs look absolutely terrible on this TV. I knew SD stations were supposed to be bad on a large HD screen, but it's worse than I expected.

If your receiver can generate on-screen text, it might be a way to check the source of the problem. If the halos disappear with a receiver generated signal then the problem is on the input side of the receiver. If not, then it's on the output side or maybe in the receiver itself. In any case, the component signal path, timing, and frequency response for the three signals has to be identical.

Just a heads up in case anyone else runs into this problem. I have a Panasonic BD-30 connected to a HL61A750 via HDMI. If I pressed the Setup button for the BD-30, the menu would appear & then just disappear. After trying a few things, I turned Anynet+ HDMI CEC off & now the menu works as it should. The thing I don't get is that I was able to use it a few times with HDMI CEC on before it stopped working. Anyway, just wanted to share so others don't sink into a fit of rage like I did before I figured out what was going on.

JD44 "Just curious, were your running at 1080p resolution?"

My Xbox wont run at 1080p via component with the tv. I posted earlier (This thread is getting long) about it messing up when switching tabs in the menu of the xbox. The first two resets happened within a half hour of trying the xbox at 1080p earlier in the week. I actually went awhile between the first two resets and the one yesterday.

I finally hooked up the Xbox 360 via Component - I set the resolution to 1080p and had no problems with the dashboard (switching tabs and other various tasks). I fired up Rock Band and got to jam to a little Boston for all of...45 seconds. I then had three power cycles in a matter of one minute. Went straight back to the dashboard and set the resolution to 1080i. Was able to play for about an hour w/o interruption (though the audio seemed to faintly "cut out" every so often).

Last night I watched another Blu-Ray disc, and set the PS3's BD settings to Always play discs at 24 Hz. That didn't help (erdamon had mentioned it appeared to help in his case). I immediately went back into the PS3 menu and disabled 1080p output and finished the rest of the movie w/o another episode.

I'm really beginning to think the 1080p resolution is giving me the fits. I'll have some more time tonight to test Blu-Ray and XBox playback @ 1080i and see if I get anything funky happening. This is getting to be borderline ridiculous -

But, as I have mentioned before, the set's picture is great. If I could just get it stay on all the time, we would be in business ;).

Can someone please confirm whether the 6189 had this limitation? Seems too goofy to last through 2 models.

So does this mean that some type of d/a converter box might be necessary for the PIP to work after Feb. '09?

First Observation

Spent about 30 min giving a through look over for the 61”A750.

The smiley face or bowing was there. Basically none, or less than 1/16, at the bottom of the screen, that’s no problem for me; but across the top from side to side, the dip in the smiley face was about 3/8”. The material for that observation was 2.35 to 1 movie loop (top and bottom black bars).

Convergence is still an issue for me, and may be related to the bowing smiley face. With the entire screen covered in letters (or any high contrast elements), it was clear to see red outlines 10-15 feet away. Blue and Green convergence was only visible to me within 2 feet of the screen. The bottom 50% of the screen had zero convergence errors, but got increasingly worse towards the top of the screen – into the bowing area.

Having owned more than my fair share of Samsungs and the flimsy thin cabinets over the last couple of years; it is possible both the smiley face and the convergence could correct itself (or close to it), with several days of long term use. Of course convergence error could be within the light engine as well – the most likely place.

One of the Samsungs most recently owned (HLT) had extreme bowing on the sides (4:3 pictures), nearly ½”. After about two weeks of playing 8-10 hours a day, all the heat from the bulb, reshaped the cabinet and screen, and the “hourglass” it had was reduced to about 1/8”. That particular Samsung was lost in the west Texas desert for two weeks, closed up in a truck in 150 degree heat. That did not do the plastic cabinet any good. Now whether or not a lot of playing (or heat), could correct the bowing in the A750 or not, I do not know.

Other observations: Excellent Samsung software and video controls and picture adjustment. PQ overall is fantastic to me, other than the pesky red convergence. In Movie mode, this set look really close to a high quality plasma to me; but without the glare. Certain elements of PQ even looked better than plasma. There is still nothing as fast as a DLP and to me that is something I can see. IMO, the red convergence, would be my number one compliant, with the bowing at the top distant second. The rest of the set seemed perfect.

This set is on my short list for Big Screen.

Couple that with the fact that when an HDMI device was not on, it wouldn't actually cycle through that input because it could tell that it wasn't on. This causes a big problem with the harmony knowing how many inputs to cycle through.

I called logitech and tried explaining this, and told them that I don't neccesarily think that it is broken or anything, thats just how the harmony remote works. Well the guy I talked to seemed pretty useless and I dunno if he understood what I was saying. After wasting like 2 hours with him, I told him I had to go and couldn't mess with it anymore, and he said he was going to pass it on to a higher tech and they might email me back with any findings. Two days later I got an email with a custom program that actually had commands that took you directly to certain inputs! And it all works great now.:) I still use this same custom program for my new TV (this 61a750).

I hope this helps with your understanding, and I would call logitech and see if they could do the same for you

I'll have to give them a call next week...I would be so happy if my Harmony could seamlessly go from watching TV to DVD and back again.

An update on my viewing issues: I adjusted the view settings from standard to movie, and while the picture is a little darker, it was MUCH clearer...I am guessing because of less contrast between light and dark colors. It's helped greatly with the pixilation issues I was having, and honestly I am watching it right now in a light filled room and minimal issues with the screen being too dark - yes, I would liek it brighter, but this picture is much clearer/more smooth...still using component cables instead of HDMI...so I might try the HDMI cable in movie mode to see if that gives me an even clearer picture, without the pixilation.

This got me to thinking, wouldn't it be nice if there was a technology out there that automatically adjusted the brightness of the set in conjunction with the brightness in the room?

For those of you who have ordered from Crutchfield, is there any negotiating on the price (although the free stand and shipping already seems to be a good deal to me)?

I tried with them just recently. Some of the salespeople might offer you their "the lowest price I can give you", others won't. Whatever you do, don't mention price matching. It is their official policy not to do that. Sot hat closes the door right away.

Very interested in the 67", but not sure I want to order another TV from an online retailer (got my HLP-5063 from TVAuthority 3 1/2 yrs. ago without problems -- I know, I consider myself VERY lucky...). But I like doing business with Amazon and trust them; their pricing/no tax is seductive, although I'm not sure it's worth the gamble until some of the issues with these sets are sorted out. :confused:

Anyway, has anyone used them for big box purchases and have any comments on their "White Glove" delivery? The policy statement says ground floor delivery; as I'm on the second floor, that's not very helpful. Are the local delivery companies flexible with that? Even if it costs a little extra, I'm OK with that.

Again, people with Slanting and power cycle issues, call Samsung. What are you waiting for?

After my last post a bit earlier today, I immediately got on the phone w/ Samsung (for the second time). The csr was much friendlier and more willing to help this time around.

I mentioned the power cycling issues I am having along with my specific scenarios - it appears to happen when I'm running in a 1080p resolution w/ any device - I have not had an instance yet in 1080i with Blu-Ray or XBox 360 but time spent in these resolutions is very limited. I did also mention that others ("thru a forum I read") seem to be having power cycling issues in different scenarios as well.

I stated I would like from Samsung:

1) acknowledgement that there is an issue w/ unexpected power cycling
2) immediate notification when a resolution is found

I let the csr know that a very similar situation has been occuring with the LNnnA650 LCD sets and that I am hoping a simple firmware upgrade (as delivered to those set owners on 4/04) will handle the issue.

I also let it be known that while I think the set (HL61A750) is very nice, one of the key decision points for purchase was the ability to do 1080p. If the TV is unable to do this w/o problems, I will most likely return the set.

The csr has stated that the issue will be forwarded to ECR (I believe the acronym expands to "Executive Customer Relations" - but I was driving at the time and could not write it down) and I can expect a response within 5 days (I assume 5 business days).

Captain obvious statement: The csr also mentioned that the more voices that are heard concerning this issue, the more likely they (Samsung) are to address the issue in a timely fashion. Reiterating jhferry's statement, all of those having these power cycling issues, let's get on the phone with Samsung and let them know. Hopefully we can start enjoying the sets as we intended to sooner rather than later.

The number I dialed for Samsung support was 800-762-7864.

Ya they told me the a750 is 60hz.Was tech support extension so im having circuit city pick it up.I ended up buying the 52xbr4 which has a perfect defect free panel for a change.I had tried quite a few 40xbr4's and all had a few dead pixels and clouding.

Not sure where that came from but the A750 display rate IS 120HZ. NOT 60HZ.

The codes in the Harmony remote database already use the "discrete" codes to move from one input to the other on all Samsung DLP models that support it (which they all do except the original HLMs). Its already in there for the 750 and probably the 650. The 750 wasn't in there a week ago, but it was a few days ago. You shouldn't have to call Logitech.

And the brightness adjustment tech-it is out there. My 2 or 3 year-old Philips LCD has it. The problem with it is it messes up the picture. When I had the LCD calibrated it was disabled.

I'll have to give them a call next week...I would be so happy if my Harmony could seamlessly go from watching TV to DVD and back again.

Just called Samsung again to follow up on the 650 specs. All that is keeping me from ordering is the contrast ratio and I STILL cannot get an answer from them about what it is.

I wouldn't get hung up on the published CR spec. For what it's worth, Rahull posted some outstanding calibration results in an earlier post (http://www.avsforum.com/avs-vb/showthread.php?p=13548682#post13548682), including a contrast measurement here (http://www.avsforum.com/avs-vb/attachment.php?attachmentid=106602&d=1207242123).

Not sure I understand that reading but is that measuring 3,018:1? Is the 750 series supposed to be 10,000:1? I am also interested more in the 650 series.

Your right, the only way Samsung will know about these issues is If you scream about them. When I called about my second 6176 they actually acknowledged issues with the set. Of course that makes it all the more disappointing that they didnt fix the bowing...

I was casually interested in this TV so I went to two stores near my house in the Toronto area. These are 2 independent dealers, on who carries Sammy, the other doesn't. Both stated that Sammy will be done with rear projection TV's within the next 4-6 months and the only person left standing on the RPTV will be Mitsu. I was a little shocked to hear that given that the new LED's have arrived. Has anyone heard about this? It could explain why they don't seem to be putting all the effort in to fix the issues...

All sign point to this unfortunately, I dont know about 4-6 months but I am guessing this is the last year. It looks to me like they rebadged last years LED with a new model name (Last years got a bad name from the bowing/Halo issues) and they took the 76 series bulb, took it out of that ultra slim cab and put it back into a slim cab. Hey, maybe they are leaving RPTV because they CANT fix all the issues. They know they cant sell unless they are thin and the thinner they go the more problems they have.

I finally hooked up the Xbox 360 via Component - I set the resolution to 1080p and had no problems with the dashboard (switching tabs and other various tasks). I fired up Rock Band and got to jam to a little Boston for all of...45 seconds. I then had three power cycles in a matter of one minute.I have watched two movies or so in 1080p/24 with only one power cycle. It recycled during a fast action screen... I'm wondering if it could be a bandwidth issue.

That reminds me... I had a TV that would flash on/off on high speed action sections of DVDs... or if there was a sudden bright flash (like lightning on a black screen) the TV would almost do a restart... this was a EDTV CRT set from..... samsung! Any chance this is the same type of issue???

Has everyone's reset happend during fast movement or bright flashes etc??... or have some been during slow moving garden or cooking shows?

What's the best way to get it to try to turn off? I have a HTPC hooked up to it at 1080p with 60hz, a PS3 hooked up (but no Blu-rays just yet), a 360 hooked up via component (until I get my HDMI cable) and a DVR hooked up via component also.

You may be on to something.

The short 30 min I got to spend with the 61A750 (the one with red convergence errors on the top 30% of the screen); I noticed each time I change menu screens, the screen would go black for 1 and sometimes 2 seconds before it would light back up again. It sort of reminded me of the Mits' ATSC tuners from 5 years ago and you would changed stations from 11-1 to 11-2 and waited up to 5 seconds at times.

The reason that got my attention on the A750, was because my last few HLT and HLS (with bulbs), changed all menu screens instantly. With the A750 (like when changing form "standard" to "movie"), that black out for almost 2 seconds sort of spooked me, until it lit back up. To me, that meant the set is "working" on stuff inside before it is ready..........in other words not enough processing power and/or bandwidth pipe to get the job done.

If you are feeding the set some of these newer heavy duty blu-rays at 1080p etc. with lots of fast action stuff, the set may not have the muscle to get the job done?

That does it for me. In 1080p Xbox 360 Halo 3 I can repeat it over and over. Take a grenade into a dark corner and drop it at your feet. When it explodes TV resets every time. Very easy to repeat. In 1080i it works fine with no resets. I am connected via component cable.:confused:

I don't believe so as it happens with standard OTA signals too.

04-06-08, 10:36 AM

I don't believe so as it happens with standard OTA signals too.
Is it possible that it's only happening with really bright (lots of white) scenes? If so, it's possible that these really bright scenes are overloading the power supply and triggering the TV to shut down. Just a thought, but if so it's possible that reducing the brightness could reduce or eliminate the problem (if nothing else it would help confirm that this is the problem).

Wow...are these EMP grenades you keep dropping? :D Sorry, couldn't resist. Too funny that the "grenade" takes our your TV every time.

It actually is very good that you can repeat this phenomenon in a reliable fashion though (good for troubleshooting... not good for you). That's one of the first key steps to troubleshooting and (hopefully) finding a fix. The more often you can create the situation the more often you can start to observe the problem.

Now... how do we get Samsung to hook up their XBOX 360 and pop in Halo3 on 1080p and blow themselves up a few times in a dark corner??

Are you able to get this to happen over HDMI as well? Are there different TV settings you can try this on to see if other settings affect your ability to recreate? (ie, game mode, movie mode, etc... sorry I don't have the set yet so kinda guessing). Can you try other component/hdmi input ports and see if it's unique to all video inputs or just a few?

good work!

Just a thought, but if so it's possible that reducing the brightness could reduce or eliminate the problem (if nothing else it would help confirm that this is the problem).

That's a good thought, gsr. Although how does this TV create "white" on the screen? I thought to make black it points the mirrors away (into a light "sink") 100% of the time duration so to make white does it point the mirrors toward the screen 100% of the time duration?

While I don't think the tilting of the micromirrors could make the power supply overload it is possible that there is something linked to processing lots of very dark and very white effects on the screen which occur suddenly which is causing the digital processing IC to consume more power than the power supply designers were asked to deliver. If this occurs then the voltage rails to the digital components will droop and probably invoke a reset of the digital board.

When the TV turns off/on does it seem to take the same amount of time as if you turn off/on the TV with the remote? Can anyone tell if the TV completely shuts down and restarts or does it seem to only power cycle some portion of the TV? (if there is a fan, does it shut off? can you tell if the light source shuts off completely and comes back? etc?)

As a side note: I was a my local BB yesterday and asked them to finally setup their floor model of the HL61A750. Within about 5 minutes of the TV working the curious floor agents had a screw driver in hand and had the side access panels popped off to look inside. After a brief period of "shadow puppets" by the BB agents (ROFL!!!) my wife and I looked inside the TV with the side access ports. We were surprised at how empty it looked in there. I also think it would be fairly easy to reach in and clear a majority of the inside of the screen this way(depending on your arm length).

I also have a 1080p Samsung LCD but when you hit 50" or more the price is through the roof. I dont have any issues with features/performance. I dont think any other DLP vendor comes close to the Samsung.

My guess is that the 61A750 wants to be transported "tall", standing up in its box (60.0" x 20.2" x 42.6", according to Samsung (http://www.samsung.com/us/consumer/detail/spec.do?group=televisions&type=televisions&subtype=dlptv&model_cd=HL61A750A1FXZA&fullspec=F)). I was hoping to cart this bad boy home, myself, but I don't have a vehicle with 43" of clearance -- though I could handle 43W x 60L x 20-35H. So I'm wondering two things:

Do the carton's this-end-up arrows point at the 20" dimension, the 43" one, or to both/either?
Has anyone loaded up and taken home a 61A750, laying down (20" tall), and subsequently found it to be free of the geometry problems some have reported?

I realize I could go with white glove delivery, but I want to retain the option to return and swap it with another unit or three if the first ones smile, tilt, or frown too much.

Edit: FWIW, a pleasant Samsung CSR just told me it could "damage the set" if the were laid down on its face or its back. Anyone feel otherwise?

Ok, just got off the phone with "Arlene" at Samsung, she just wanted to send a tech (which I explained to her was going to be a waste because it is probably a firmware issue, isn't just my TV (I've had blacking out on both sets I've had and power cycle (it didn't come back on) on the current one). I said I just wanted to be added to the list of people that had the problem. She said there is no list, no firmware upgrade (duh, its a new set) and at that point just wanted to get off the phone with me <grrrr>.

Earlier today, I was able to reproduce weird video issues, black screens, and just one time I had a power down on the 360 menu, if I go into the "Inside Xbox" section and flip through the screens (these are bright screens). I also have the Xbox video camera hooked up which makes my background unique.

I will try the Halo 3 thing soon.

Does not happen on anything except 1080p, I only have component, no HDMI on my Xbox.

I am going to try some more with my HTPC and see what I can do in the HDMI realm.

Perhaps with the XBox, yes, but not so far with Blu-Ray playback (via PS3). The resets all occurred during rather slow paced sequences. No Country for Old Men, Spider-Man 3, Good Luck Chuck (wife chose that one!). I tried playing back the same sequences to see if I could get the power cycle to happen again immediately with no luck.

Please forgive me if this is a stupid question. I just received my HL50A650 which should be 120 Hz. My questions is how do I get it to perform at 120Hz? I have a directv hd-dvr hooked up via hdmi and it is at 60hz.

You do nothing. It is always doing 120Hz processing. When you press the display or info button and it shoes 60Hz, that is showing you the frequency of your INPUT. The set internally runs at the same rate, just like the resolution the set displays is always 1920x1080p, regardless of what you feed it. That's just how these DMD sets work.

Sheesh! No offense, but getting tired of the same old questions asked over and over again. It is 120Hz.

I have a couple of quick questions. Don't worry, none of them have to do with 120hz. I was about to buy the HL50A650 until I started reading some of the posts here. I haven't read through every page of this thread (way too long), but I was wondering the following:

1. Are the problems mostly involving Samsung's new LCDs or do the DLPs have a lot of problems as well (specifically the A650)?
2. People have been mentioning firmware fixes. If this TV does have problems, is there a firmware fix available?
3. How do you apply a firmware fix to a TV?

Rockband party went without a hitch... no resets with PS3 over component and max res. set to 1080i with about 5 straight hours of playtime.

The resets that I did have were during slow, normal scenes. Each time I backed up and the scene played without a problem the second time. Very bright scenes (over cable) do not give me any problems. My previous TV a 30" Samsung CRT would flash green through many very bright scenes.

Thinking about getting a Samsung BD Player for $399 as another 1080p source. Need to make sure I can return it after my testing period.

Mine has power cycled a few times in the last hour running about 10 hours the past two days and I get the little intro music when it's turning on/off.... I am using a HD Dish Network box with HDMI... is it because I do not have HDMI 1.3 Cables, or is this just a glitch Samsung has to fix?

Which model TV are you having these problems with? I am possibly getting the 50A650 DLP. Is that TV having the power cycle problems?

Hi all.. I've been waiting 6 months to buy a new tv.. first sony ditched RP on me... and now this one seems a bit 'glitchy' .. I'm scared I'm going to end up with no options for a really big tv

I'm new to the game so can someone tell me if things like the reset etc. are possibly just symptoms of a 'new' (assuming this truly is a new) line of televisions and can possibly be fixed with firmware updates etc. ? I had my heart SET on a big tv 65 or bigger and this seems like it could be my last option (if it ever indeed comes to Canada anyhow)

aside: I was just at a home show and asked a guy selling panasonic plasmas why they stopped making RPTV's .. he said better picture/not bulky/lower cost of manufacturing... yada yada... I challenged with 'so how many people actually put them on the wall' and he said he was from so and so (high end store I guess) and all their customers did... he did show me a 58 inch plasma and I have to agree it looked great (4000 bucks or so)... but of course the 65 inch was 7500 bucks... I didn't take the time to ask why if it had lower costs of manufacturing it was still way more than a 65 inch RP would be..

also future shop guy tried to tell me the last sony they sold here (a 2000 ? or 2020) was still good and they had one demo model left.. I passed

I am having this issue with the 61750.... not sure whats going on

I may be wrong but it looks like the power cycle issues are only with the 750 series? I have not seen the 650 owners complain about this unless I am wrong. Any 650 owners going through this?

I've had my 56A650 since Friday and I've had no issues with cycling or bowing...but I'm not a gamer so no PS3 or 360 being used.

You know maybe I'm just oblivious but I turned on some ESPN, MSNBC, etc and don't see any bowing issues..... and so far no power issues on my 61A750, it'll hit me at some point I guess....

Flat-panel sets are easier for manufacturers to manufacture consistently (like solid-state electronics always is). The production lines can be more completely automated. Also, unlike RPs, all their components are laid out on a flat structure, which helps keep everything in line and makes them more rugged. You almost never hear of geometry issues with flat-panels.

I've been completely happy with my G-series JVC D-ILA for 2 1/2 years and 12000 hours and am not in a hurry to replace it, but I know I've been lucky. Would I buy another if they were still being sold? Probably not. The technology is simply improving too fast, and there is no guarantee that my next set would be as reliable.

I don't know Smidget, maybe we just got lucky and got trouble-free sets. I keep waiting for mine to shutoff but it hasn't happened yet.

Just to reiterate, I have had no problems whatsoever running at a resolution of 1080i.

If I run Blu-Ray playback at 1080p, the power cycling is intermittent (it happened three times over the course of 7-8 hours of viewing).

When I hooked up an XBox 360 (via component) and set the resolution to 1080p, we couldn't play a game for more than a minute or two. I immediately bumped the resolution down to 1080i and had no further issues.

HDMom, you mentioned you had no problems with Blu-Ray playback...do you know perhaps what resolution you are running at when viewing?

Well, from what I have read, it looks like 650 owners aren't experiencing any of these glitches. I am planning on going to get the 50 inch set at CC tomorrow. It is currently listed online for $1450. Should I go through with it?

The 750/650 LCD versions from Samsung also had the power issue, but it has been fixed by a firmware update. The issue may be the same, but the urgency to fix the spendy flat panels was greater than the cheapskates buying RPTV.

Maybe the problems with the 750 line are coming from the use of the new LED light engine. The 650 is still using the previous generation tech, which didn't have this power cycle problem.

Keep calling Samsung guys... Especially If you can replicate the problem.
Just to be clear, I don't own one of these TV's - I'm just a (somewhat) innocent bystander. I'm most likely going to replace my ~6 year old Mitsubishi Diamond series RPTV with something later this year, so I'm paying attention to various options including DLP and the Pioneer Kuro line (yeah, I know these are radically different price tiers). All the problems people are having with these DLP's has me pretty much convinced to go with the Kuro option even though it will cost significantly more.

I completely agree that those of you having problems should be calling Samsung to complain. Nothing will get fixed if they aren't aware of the problems and the odds of something happening increase if more people call. Quite frankly, if I paid a few thousand or more for one of these sets and had bowing or random power shutdowns, I would exercise my return option and get something else. Nothing will get their attention more than lost sales.

Quoted from the HL61A750 owners manual page 13:

"The TV may not output sound and pictures may be displayed with abnormal color when DVD Player or Cable Box / Satellite receivers supporting HDMI versions older than 1.3 are connected.

When connecting an older HDMI cable and there is no sound, connect the HDMI cable to the HDMI3/DVI IN jack and the audio cables to the HDMI3/DVI IN [R-AUDIO-L] jacks on the back of the TV.

If this happens,contact the company that provided the DVD Player or Cable Box / Satellite receiver to confirm the HDMI version, then request an upgrade.

➢ HDMI cables that do not support HDMI version 1.3 may cause annoying flicker or no screen display"

I have a motorola dch 6200. The picture on the a750 is worse then on my old hlp6163. It appears grainny on bot sd and hd. The color is blurry and theres like a lot of mosquito noise. I have tried all dift kinds of cables. All different kinds of settings. Im hoping its because of the cable box cause i know it isnt hdm1.3 but an older version like 1.1 or 1.2. Still ive tried every hdmi outlet and it still bad. Anyone else having crappy picture via hdmi in on a cable box?

I have had the 61A750 since Fri.4/4/08, from crutchfield,free stand,free ship. Replacing a 7 year old Mits ws55807 rptv (eliab calibrated),the 750 is so much better in every way. Connections include cablevision digital converter SA4250HD (hdmi) to TV, Denon DVD2900 to TV via component cable. Both sources are gorgeous on this tv. No blu-ray yet. No issues have developed, however I can see that red convergence is off very slightly to the right top of the screen. Thus I'm currently satisfied (Knock on wood)

only issues I have had was a few power cycles, kinda weird, and my PS3 I think is only playing back at 1080i not 1080p... by the way the powercycles happened when I was watching HD via Dish Network HD SET TOP BOX...Surely it is not because I'm not using HDMI 1.3 cables? Also no clue why the PS3 wont do 1080p... it says Automatically will detect 1080p

HDMI is not the problem, and I don't care what the manual says.

HDMI 1.3 is fully backward compatible with previous versions and adds the following features:
1. Increases single-link bandwidth to 340 MHz (10.2 Gbit/s)
2. Optionally supports 30-bit, 36-bit, and 48-bit xvYCC, sRGB, or YCbCr with Deep Color up from 24-bit sRGB or YCbCr in previous HDMI versions. In terms of number of color combinations 24-bit allows for 16.7 million colors, 30-bit allows for 1 billion colors, 36-bit allows for 67 billion colors, and 48-bit allows for 281 trillion colors.
3. Incorporates automatic audio syncing (Audio video sync) capability.
4. Optionally supports output of Dolby TrueHD and DTS-HD Master Audio streams for external decoding by AV receivers.[9] TrueHD and DTS-HD are lossless audio codec formats used on Blu-ray Discs and HD DVDs. If the disc player can decode these streams into uncompressed audio, then HDMI 1.3 is not necessary, as all versions of HDMI can transport uncompressed audio.
5. Availability of a new Type C mini-connector for devices such as camcorders.
(thanks Wiki)

Prior versions of HDMI had a maximum bitrate of 4.9Gb/s (enough for 1080p/60) and supported 8 channels of 192/24 uncompressed audio. There is nothing that you guys are plugging in that is going to exceed that spec. None of the listed sources in this thread include Deep Color in the signal and nobody has mentioned sending an HD Bitstream. The only current use of 1.3 is allowing HD Bitstreams to be sent to a receiver for decoding instead of in the HD player. No TV can do that currently.

The reset problem isn't the cable. Or the interface. Something in the system is creating a hard error and causing a reset or something is overheating and doing the same. If it is the same bug as the LCDs have it can be fixed by firmware. If it is a heat or powersupply problem, the service technicians are going to be busy. If Samsung hasn't addressed this issue by the end of the month I would consider purchasing one of these TVs to be an act of stupidity.
