So in your link for Game Mode, is that 60ms lag with a 16x9 setting or Just Scan setting? Assuming it is with a 16x9 setting, then what is the lag time with Just Scan?

Thanks for taking the time to analyze this. I would be interested to know even thought I recently bought a LCD Alienware computer monitor with only 2ms lag time

Does anyone know where I can purchase a replacement housing piece (external casing) for my 46" 750? It appears samsungparts.com and the handful of other parts merchants only sell the front bezel.

I'm using my 40a750 for almost 18 months 7/24
It is the best purchase of electronics i ve ever made. It is my regular pc monitor,hd satelite tv,ps3 360 gaming center. blacks are still perfect "0" bl bleed, awesome liflike colors, reliability knock on wood. Never had to call service for repairs Just bought a new led samsung xl2370 pc monitor and it looks crap compared to my 40a750. It went to my sisters apartment as gift a750 rulez.

Best bet would be to find a crapped out unit and take the casing from that.

That's what I fear. Guessing my chances are pretty slim.

Thanks for the reply.

Hello - I have an LN52A750 (LN52A750R1FXZA manufactured 9/08) that has the dreaded power on issue where it constantly cycles by clicking on and off, but never boots up. I have read that many other people on this and other forums have the same issue with the problem being blown/leaking cap's on the main power board. The first thing I did was call Samsung, but they are unwilling to honor any type of repair since my tv is a few months out of warranty (purchased 1/09), regardless of the fact that this is a widespread problem. Anyway, there are tons of diy capacitor replacement for these Samsung tv's on the web, so I figured I'd give it a shot. I took the back cover off of my tv last night, but in my case, all of the cap's look good (no buldging at all, tops still flat, no evidence of leaking). Could this still possibly be a cap issue even though they look good? When my tv failed, it was sudden. Up to yesterday it has never had a problem. Yesterday we watched a show, turned it off for an hour or so, and then tried to turn it on again and the problem started. It has not powered up since and I've let it do its clicking cycle for up to 15 minutes numerous times. It seems others have had more of a gradual failure with it powering up after clicking for 5 minutes or so and getting worse over a period of weeks. Do this indicate mine being a different problem? Any advice would be greatly appreciated as I don't have hundreds of dollars to spend for a tech repair. Thanks, Jay.

Question, when your set turns off and on, does the red power light go onand off? My set will go black for 2-5 seconds and then the picture returns, but the power light doesn't flash. I was thinking it was cable because my Toshiba does it but not at the same time.

allornothing, there are certain Motorola DVRs that started doing this after a recent firmware update. Mine did several months ago when Comcast pushed out a new release. So far my research show it's it being something to do with the HD in the DVR that is constantly recording the current channel.

It even happens during playback of a recorded show. You can rewind a little and it will NOT repeat. Very random event

CH, Thanks that's what DVR I have and they did a software update a few months ago and I had to have one replaced after that. I hope it isn't affecting the TV with the on off picture.

I just bought a new TV and I'm now wanting to sell my LN52A750. I found 2 people who want to purchase the TV. How much should I sell it for? I was thinking $1300. Is that reasonable or too much? The TV is in perfect condition.
post #12373 of 12492
I wouldn't spend that much money to get a used tv. But that is just my opinion.

I found about 7 or so online selling around $1500 used so that's where I based my $1300 price at. I just wanted to get other opinions on selling price.
post #12375 of 12492
It isn't necessarily a bad price for a quality 52 inch tv, and you may find someone that is stoked to find that deal. It just wouldn't feel right to me to purchase a used tv for that much money. But my opinion is probably irrelevant here.

Give it a whirl. You can always leave room for bargaining.
Good luck!

How fast are those $1500 sets going?

Who knows. Surprisingly, Amazon still has one new one left in stock. It's selling for $2193.62. Amazon Warehouse deals are selling used ones for $1240.99 with one at $1529.99. Maybe I'm wrong, but if I sell it now for $1200, I don't think that's a ripoff. The LN52A750 is a good quality TV, plus it's not that old.

Now that 3d viewing is getting popular, does anyone know if NVIDIA's 3d gaming/TV technology work on this display?

I bought a Ln46A750 almost 2 years ago, and am really happy with it. Upgrading my PC at this moment, but don't really need a display upgrade. Just wondering if the NVIdia 3d glasses technology works on our fine displays.

I recall that this TV has a 120 Hz AMP mode - is that compatible with the 3d technology? Anybody tried this yet? Googling didn't help, though I noted that this TV wasn't on the list of TVs that are working with the Nvidia 3d technology...

I've owned my 7 Series 52 inch for about 18 months and now the tv will turn on and turn off and keep recycling itself and will never start off. It just keeps turning off and on! What exactly do I do? And what is the problem?

Please, anyone that knows it would be really helpful!

Does this sound like your issue? http://www.avsforum.com/avs-vb/showt...3#post17748973

There have been a number of people in this forum that have reported this issue of bad capacitors. Do a quick search of the forum thread and you will find a number of posts on it.

You should get a service tech out there if it is still under warranty. Otherwise, someone documented the home fix here. http://www.earthinfo.org/samsung-tv-...licking-sound/

I hope that helps.
Good luck.

I have a problem (LN40A750R) where on power up the top 1/3 of the screen "doubles" or repeats itself on the next 1/3 of the screen, mostly visible on the left side of the screen. This goes away and works normal after some "warm up" period (anywhere from 1 minute to sometimes 10 minutes).

The TV is EXACTLY 1 year 1 month old (off warranty wouldn't you know it lol).

Called Samsung support, no help there, sorry to hear you have a problem and call the local Samsung service depot...

Any thoughts on possible causes of this situation; or if someone has heard of similar problems? Really don't want to take this to repair $$ shop if don't have to.

Thanks in advance.
post #12382 of 12492
Mine is doing that too...

I just came here to see if this is a know problem... 1/3 screen etc..

Managed to snag a 750 (panel only) for a great price. Does anyone know what other parts I need to assemble a whole unit? I'm thinking the housing and bezel? Anything else?
post #12384 of 12492
Hi have had my A750 for about a year and 4 months. it has worked flawlessly since now. the problme i am having is when i start the TV it will go through the audio "start up" notifier where it plays that little samsung sound, but anywhere between immediatly and when its almost through the audio tone it just stops and resets and does the audio tone again. and again...and again. at first it only did it 3-4 times and now its gotten to the point where ive been waiting more then an hour and it still isnt "warming up" or completing this audio tone cycle. im not sure if this was discussed somewhere else in the thread...being as there is like 400 pages i didnt get to read through them all. anyone ever have a problem like this? or know how i may fix it? firmware update? i do have a in store warranty that i will fall back on if needed. thanks for helping me out. *hopefully*

Situation has progressively gotten worse....now need to give the TV a quick rap on the left side for the thing to start operating properly. Have written a formal letter to Samsung asking for "clarification" on their support.
post #12386 of 12492
Hi all,

I have the LN40A750 bought in July 2008 (At least I think it was about then).

A few weeks ago mine started the clicking and taking longer and longer to power up. After about a week or so of this it would just keep trying to power on, but never quite make it. I to had the chimes starting and stopping. One day I left it running from about 9AM until 12PM and nothing. Just every 5 seconds or so DING-DING-DING-Click-DING-DING-DING-Click

I called Samsung and asked about this. I told them that I was outside of my warranty period (Not that they wouldn't know real quick anyway), but that I had seen a lot of internet posts about this capacitor issue and that Samsung was extending repairs to people if it did indeed turn out to be the capacitors that needed replacing. The rep I talked with "pulled up my file" and said since I was such a loyal Samsung customer that they would indeed extend a one time service call even though I was out of warranty. They gave me a 400 repair number and told me a tech would contact me in the next couple of days.

The next morning a local TV repair center called and asked if they could come repair my TV later that afternoon. The tech came and in about 20 minutes he had the caps removed and replaced with new ones. He stated that this was actually his 4th Samsung that day and that he had been fixing a lot of these capacitors. He even predicted which capacitors would be blown out before he removed the back of the set. Sure enough it was the ones he said. As soon as he took the back of my TV off, it was very apparent that it was indeed the capacitors (Mine had domed out pretty far). Once removed and replaced the TV has been fine.

The only problem I had was during the inital conversation with the repair center. They started quoting me prices to repair the TV. When I said that I thought it was under Samsung's warranty, he stated that Samsung had listed it as a non-warranty call. He told me to call Samsung back and get them to send him the repair request as a warranty call. I called Samsung and spoke to another rep and within 5 minutes she had it resubmitted as a warranty request and resent to the repair center. The tech came that afternoon and my TV has been running fine ever since (Now on day 10 or so). No charge out of pocket to me for the repair. The tech did state that this type of repair would have been between 150 and 200 if I had been paying it myself.

So even if you are out of warranty, you might want to try and give Samsung a call. When I spoke to the first rep I simply stated the problem that I was having seemed to be a fairly widespread occurence. He wouldn't comment on that, but the fact that they were willing to repair this out of warranty (And nearly a year out of warranty) seems to indicate to me that they know something is wrong and maybe this is just their way of fixing the issue quitely. I didn't even have to yell or threaten to never buy another Samsung product again, they just simply offered a one time service call.

YMMV, but might be worth a shot.

Best of luck.

Thank you so much for the heads up. Your experience might be very helpful!

I bought my LN52A750 back in 8/2008, and yesterday I found that the VGA input on my TV is no longer working. I have been using it regularly, to connect my laptop to the TV. But now, the laptop does not recognize the TV anymore. I have tried with 3 different laptops and 2 different cables. I cant see any visible damage to the VGA female ports either.

Any ideas anyone?

So why limit DLNA to the hard wired ethernet connection. Wireless would make this a much more versatile unit. So far, this is my biggest problem with my TV. I would much rather have this TV in room other than my computer/router but I don't want to crawl in the attic to install the cable. I think Samsung messed up with this limitation.

Get a wireless bridge set up, that's all you need if you don't want to run wires all over the place, not a dongle but an actual bridge, like a wireless gaming adaptor.
