Image burn in on LCD TV

[Rich3077]

Well I thought it was impossible but my 3 year old 42 inch LCD Insignia brand TV got a bad case of image burn... had the web browser burned into it.

It was under Best Buy warranty but I don't think it was a covered problem. The tech who came out was cool and found other faults with my screen that resulted in the TV being returned for its full value that it was purchased at.

With my Best Buy store credit I bought an LG 47 inch LCD.

Do I need to worry about image burn on my new tv or was the image burn on my last set a fluke??

I have been using LCD monitors for years now without image burn so I have no clue why it would happen to a tv. For the record the owners manual came with a warning about image burn and how to prevent it.. and stated that its not a warranty covered issue.

I have Googled this with limited success... seems it kind of rare.

Thanks
Rich

How long did you leave it on?

It should go away with time though, I left an LCD on in cold weather for over a week while I went on vacation (forgot screensaver/sleep was off) and I came back to a desktop still visible for a couple days.

It eventually went away after the set warmed up and got use and if you turn on said LCD (its over 7 years old) it will look just as new.

What you described was image memory with an LCD. It is correctable with playing back different random patterns for several hours (depending on how bad it was). That said, I do know there are some coatings put on the screen which may have reacted poorly to a constant bright white light and may have aged non-uniformly.

The LCD's in my camera monitors are burned in with the shape of the app and the image grid. If I cared enough it is easy to fix with some of those applications that image shift random colors quickly. Unlike CRTs the image memory is completely reversible in nearly all cases.

i've seen commercial units take damage from years of burn. i wonder how that works. the twisting doesn't return to its original shape?

make you should degauss it
