I got this unit from my employer, who was going to toss it out as it was no longer working. After replacing the T-Con board, the unit operates fine, but has a very bad case of "burn in" on the edges from the TV displaying a static image for a long time. My question is, does anyone know of a process or product that seems to help resolve these issues? I have tried a couple of suggestions and I have seen a few products advertised, but I don't know if they really do anything or not. I'll entertain any ideas at this point, so fire away.

Can you post pix of the burn in? Do you see it on an all black or white screen the best?

I will get a couple of pictures tonight and post them. What I've tried so far is running an all white picture, with the contrast turned up to full, for several hours. I have also tried running a channel with no picture (salt and pepper fight) for a similar duration. If either of these had an affect, it was slight at best. The ghosted image is probably from more than a year of constantly displaying this border image, so I'm not sure if there is a possibility that the damage is perm and can't be fixed short of replacing the display itself. Maybe one of these methods would work if I ran it longer? I wasn't paying close enough attention to if the image was more pronounced on black vs white, but I will verify that when I get the pictures.

The ghosting shows much more during color or white screens, but a white screen with the contrast turned up washes it out. Here are pictures of white and blue screens at 50 contrast. Ill have to post pictures separate since im on my phone right now

My honest opinion, that's not going to come out. I've dealt with some slight IR/Burn in and it took many hours of "video snow" with the contrast & Backlight at 100% to get it out. That's with some images that's very hard to see. Yours looks way too visible to be able to get rid of. What was the longest duration of video show did you do? What contrast & Backlight settings?

I know this is going to sound very extreme to you but even with slight IR/Burn in 4hrs is WAY too low. If I had your TV I would have to start with 24hrs of snow with 100% contrast and backlight and go from there, and thats to see if there is even a slight improvement. That burn in you have is from a very long static image and it's going to take extreme help and that's even if it will help. With my Plasma I had 2yrs ago was very bad with IR and I fell asleep one night with the history channel logo in the corner and I noticed it for days after, mostly when there was a white or solid color on the screen, well I had to do the snow method for like 18hrs and that made it go away. I hated that damn TV.

24hrs playback and check to see if it will even be possible to remove.
