How do I reverse the screen burn in on my HD television?

I have a 55 inch Mitsubishi projection HD television (model WS55315) that is about two years old. Within the last month it has developed a burn in image in the lower right corner. Can I do anything to reverse this burn in?

If the set is CRT based, there is not a whole lot to be done. In the future, you could try turning down the contrast to avoid any further damage. If the image is really in there (as in, really badly burned nothing will fix it). I have seen cases where the image is not that badly burned into the phosphorous of the CRT. Running the set without any logos or things like that can eventually be minimized. Also avoid leaving the set muted for any length of time. I repaired a Mitsubishi set once that had the word MUTE burned into the screen. Fortunately, the CRTs were to be replaced under a recall at the time (V10 chassis). I did show the customer what had happened because of the muting being used all the time, instead of simply turning the volume down. They were astonished, and had not noticed until they had new CRTs installed in the set.

If the set is a plasma type, the image will eventually go away, if you stay away from what caused the image in the first place, again try turning the contrast down on the channels that use a logo (opaque), instead of a watermark (translucent).

If you have been watching your TV, on various channels, with various content on the screen, and the burned-in image has not improved itself by any visual difference...

...then there may be nothing you can do to completely fix the problem. However, if the burned-in image appears to be softening/disappearing slightly over time by watching various channels/content, then continue with doing that. Or watch shows that have brighter images, preferrably outdoor daylight scenes.

Overall, avoid viewing whatever seemed to cause the burned-in image for a long time, until the burned-in image is nearly or completely wiped clean.

This is a solution that tends to work for Plasma TVs, and it may work for your projection style TV, at least it's worth a try, (if you haven't done so already).

By the way, for your next TV purchase, look into a LCD TV. LCD TVs do not have the 'burn-in' problem nearly as much as projection or plasma TVs, (though it is possible to have image retention on LCD TVs too, but it's much harder to achieve).
