How to fix LCD TV image burn in
Image burn-in is one of the most commonest of problems that plague LCD TVs. Well, this is not completely true. Image burn-in or image persistence is actually quite rare in LCD TVs, unlike plasma TVs. So, how does this happen? Static images is the answer. If such unchanging images are displayed in an LCD TV screen for long time periods, the image tends to get ‘stuck’ on the screen.
This is because, if an LCD TV screen is exposed to a particular voltage for a long time, the liquid crystals get used to the comfy feeling and decide to stay in one place. This effect, though not extremely irritating to the eye, can cause minor disturbances while watching TV. Getting rid of LCD V image burn-in is quite easy, actually.
Method – 1:
Run a completely white screen saver in the TV for 48 – 72 hours. You can run an all-black or grey screen saver instead as well. The reversal of the burnt-in images can be accelerated if the same process is done at temperatures ranging between 30ºC and 40ºC.
Method – 2:
The image-burn in can also be reversed by keeping the TV turned off for a long period of time.
Method – 3:
You can put-together a slide-show of alternating full-screen color slides and display it in the TV for several hours. (48 – 72 hours should be enough for most cases.)
Method – 4:
Interactive DVDs that claim to get rid of LCD image burn-in are also available in the market. You can try them if you’re willing to spare a few pounds for the process.
Like they say, prevention is better than cure. The best way to ensure that your LCD TV is not affected by image burn-in is to switch it off when not in use. Also, do not display static images for long periods of time.
