post #12451 of 12492
That's good to know if my tv ever starts doing that. Thanks!
post #12452 of 12492
Hello all. I have come into possession of 2 firmware updates not available on Samsung's site. When a tech came to my house recently to replace the infamous CAPS, he provided me with what he said was the "newest" firmware at my request. That is version 1013.00 and I have updated it just fine, and it is, based on number and date, newer than the 1012.12 version currently hosted on Samsung's site.

My backwater dwelling of the net has also brought me to a 1014.00 firmware which I have, but have not the balls to test myself. If anybody is interested in either of these updates, please PM me. Thanks!

Did you notice any changes to the picture quality or menu?
post #12454 of 12492
My question exactly.
post #12455 of 12492
Nothing readily apparent
post #12456 of 12492
It has been so long since I have flashed a firmware. Does it reset the tv? Will I lose all of my settings (calibration, channels, etc.)?
post #12457 of 12492
Hmm, I am not sure if it did or not. I always reset things before and after a flash so I am not sure to be honest.
post #12458 of 12492
I'm in need assistance with the service menu for the 750 model 1012 firmware. I reset in the service menu just fine. However, upon snooping accidently changed a power setting (PWMR_EXT) of some sort that cause the back lights to immediately turn off. Now, upon boot I hear the boot sound, but can't see anything. Thus, it hard to reset again. Can anyone assist? Service main menu pictures may help me navigate to it again or reset. I'm also willing to attempt the 1013 update mentioned here, if I can somehow flash it without being able to see anything.

Thank you in advanced.

FYI, just found the service manual. This place ROCKS! I changed Dimming Select off EXT_PMW, then it went dark. Any recommendations?

My 46" just started the capacitor problems. Three days from clicking and taking longer to turn on to not turning on at all.

It's covered under the class-action suit. Repair tech coming out Friday.

If it wasn't for this forum, I would not have known about the class action suit.

Thanks all.
post #12461 of 12492
I am glad it is working out for you.

I called 3 times. No help.



Hi, did you have any luck finding out what's causing this issue? I have a LA40A750 (australian model I believe) thats being doing the screen flicking/tearing thing for the last couple of months.

At first it would fix itself after being on for 10-15 minutes, but now it stays like that more times than not.

Apologies for first post dragging up an old thread, just curious if there is any way of saving this tv.. it's driving me bananas.

I have an LN52A750 that has developed a vertical red line ,first one pixel now 2 pixels wide top to bottoming left side(wile facing) . It seems intermittent more on startup then Goes away after a wile . I have a 4 yr extended warentee from best buy that they just sent me an email stating it was about to run out ! So I gave them a call to see what they could do? They sounded like they wanted to help --- from Texas to Montana I'm in hudson valley ny. The 1st tech canceled
And haven't heard from the second yet?? -- haven't found much on vertical line problems/Solutions so I was wondering if I might except -- Repair/ replace ?

post #12465 of 12492
I have a LN52A750 manufactured in Feb 2009 that has officially been diagnosed with the "capacitor issue" by Samsung customer service. Since my TV was manufactured 2 months after the close of their class action period, both Samsung customer service and their Executive Customer Relations department were unwilling to do anything to resolve my problem beyond referring me to a "local" authorized repair shop that was over 60 miles away - and one that no longer does in-home repairs. So, not only do I get to pay for the repair myself, they advised me to drive over 100 miles round-trip to to get my TV fixed!

I am extremely disappointed not only with my Samsung product, but also their complete unwillingness to acknowledge that they are STILL having the same problem they were sued and settled for! I sent an e-mail to their CEO to express my disappointment.

Needless to say, I will NOT be buying another Samsung....

In the meantime, can anyone direct me to exactly which PCB I need to buy to fix this problem (TV powers on, powers off, powers on, etc...). Samsungparts.com has 4 different PCB's available for this TV with no description to assist me in determining which one I need!

Thanks!
post #12466 of 12492
I have the exact same issue as PhinPhan54, above. I called Samsung and was told that my TV is a 2009 model and is not covered under the Class Action Settlement.

Obviously, Samsung may need to spend some more time in court before they cover the line of defective TVs.

My TV is clicking and going through an on-off cycle for as much as 3 minutes now. When this problem began last week, the TV would turn on within 30 seconds or so. Things are getting worse.

If anyone can provide any information as to how to repair this problem, it wold be greatly appreciated.

Good luck to PhinPhan54... it doesn't look good for us.
post #12467 of 12492
Well, so much for my TV starting up in 3 minutes or so... it's now been clicking and restarting for about 3 hours and will not display a picture. frown.gif

It's a sad day in the neighborhood.
post #12468 of 12492
More than 4years old, still loving our LN750A52, great picture and sound. Viewing/Sitting is at almost 20' and comfortable.

The Samsung replaced a 40", Westie and the 750 has been a great choice and we have no issues and no regrets.

In all it's glory, 750 is mounted on multi-directional Kanto mount, concern for, fireplace heat has not been an issue



If ever to replace, a 70" would be considered...but in meantime, all is good.

Hey there, got one of these Tv's for around 300$. The tv seems fine for now, i do hear clicks from it, when it turns on and turns off...

I bought it from a guy who fixes tvs, 3 month warranty so I do have alittle bit of peace of mind..

I want to think this is a great tv, but then just yesterday the picture went weird for asec and it went to check signal cable, and then came back to my ps3 game afew moments later, it hasnt happened since and ive been testing it out all morning to try and get it to replay the problem...

Im just hoping my tvs fine. It plays youtube videos and everything from my ps3 and i did make sure to check the hdmi connection right when that issue happened...

Are these ticking noises sound of bad caps, or bad psu. or something that is worth warrantying or just a normal part of this TV

I figure @ the price i paid, if it will last even a year its well worth my money spent
post #12470 of 12492
Clicks when turning on and off are normal. What''s not normal is repeated clicking and the TV turning itself on and off.

I am an 850 owner and my tv clicks but doesn't turned on. A description on there class action law suit matches my issue.

If I unplug tv, weight 2 mins, plug it back in...it works. I was informed by Samsung I do not qualify under class action lawsuit as my TV set was manufactured in January 2009....I probably missed it by a few days. mad.gif


I planned on calling ECR but now I'm not so sure what to do or how much it would cost to fix it.
post #12472 of 12492
Old thread, but just had the capacitor issue for the second time. Was checking my old posts and the last repair lasted less than two years.

The first time around samsung would not cover it, but a google search brought up that class action settlement so free one time repair. I do wonder if they covered it the first time, if they'd also cover it this time with the settlement now in place

Had two bad capacitors. The tech brought another power board with new caps so it was an easy swap. He mentioned that they replace the caps in shop.

I asked about using upgraded capacitors, but said they use the original ones and not to bother with anything else. He also said that some believe that if you use higher rated caps that they will last longer, but that was not the case. He seemed like a nice guy and all, but was probably giving me the samsung spiel.

Also have a pair of c630s that are probably approaching 3 years old now.....hope those don't suffer the same problem.
post #12473 of 12492
Oh and if I knew about this settlement earlier after being denied a free repair by samsung a few months prior, I'd be pretty annoyed. Guess it all works out though.

Hey guys, I'm having the same issue as Norm.

I found this thread but I'm not sure it's the same problem or correct fix for our issue:

http://www.avsforum.com/t/1173106/kdl-xbr4-half-the-screen-dark-with-slow-pixel-refresh-all-inputs

I also tried replacing the T-Con board to no avail. I fear the panel has gone bad but I am really hesitant to call it quits on this TV just yet. I mean, before this happened it was an excellent TV and now 5 years after having bought it, it's going south on me. I guess 1300$ doesn't get you what it used to. And of course Samsung won't do anything but tell me it's 200-700$ to fix it. The refurb on Amazon isn't even 500.

Here are some pictures of the problem I am having. Any and all suggestions are appreciated and I am moderately good at hands on DIY stuff.



post #12475 of 12492
Hey, does anyone know where to get the firmware updates now that they're not on the Samsung site? I have the Canadian version of the TV, although I'm not sure what the difference is.

EDIT: Also, the red border seems really faint on my TV. Is the US model different?

I put some pics of the problem are below

(sorry about the size but I don't know how to do thumbnails):
TV just powered ON






TV after a few minutes




TV finally back to normal

My tv has started doing the exact same thing. Were you able to resolve it? If so, would you mind sharing? I would greatly appreciate it.

The only problem I seem to have with my LCD TV is that when ever I turn it on it has a blurring effect or double effect and after about 10 to15 mins it goes away and the picture become clear. I can speed the process up sometime by lightly tapping on the side of the right side of the TV. So any ideas, Mainboard, power supply board, tk board, Ld board, or just junk it and go with a cheaper version LCD b/c SAMSUNG truly sucks and I'm out of a warranty.

Were you able to resolve this? I am having the same issue.

Hello, someone just PM'd me to ask if I solved it and I did. So thought I should just post here, since others are having the same issue.

The problem for me was the Tab Bond on the LCD.
This is an "easy" fix BUT taking your TV apart is not for the feint of heart.

You're probably going to need to turn on and test the TV too while it is all in pieces and all the High Voltage innards are exposed.
This is necessary to determine which Tab Bond is the problem.

I really wish I had the links to post but i can't find them.
Google "tab problem on lcd" then try finding one for your specific tv.

I had to get the Service Manual for taking apart my specific TV. That had pics and it helped a lot to put it back together

Other than screw drivers etc, the only other thing you need are silicone bumpers:
http://www.amazon.com/3M-SJ5312-Bumpon-Blister-Clear/dp/B000NG60SW

The thickness you get is important because if it's too thick you won't be able to put the TV back together or you'll put too much pressure on the LCD.
If it's too thin, you're not putting enough pressure and the Tabs won't connect properly.

Hope that helps!
post #12480 of 12492
Thank you so much for posting this. I think I might open my tv up this weekend!
