That would depend on the set but generally if the contrast is set at a reasonable level and you are not keeping graphics on the screen 24/7 you should ot have a problem.

With all the digital technologies, it cannot be an issue at all, even if you were to crank up the TV's settings so you could see nothing but white. LCD, DLP, LCOS.

Plasmas can get burn-in and LCDs can also get something similar called "Image persistance", but it's quite a bit harder for LCDs from what I've read (in most cases very unlikely), but definitely not impossible. Of course with LCD it's referred to as "image persistance" since I believe it can be fixed unlike CRT or plasma burn-in:

DLP is 100% immuned though.

Image persistence is a memory effect in the liquid crystal. It goes away with a couple power cycles, which actually means running screens of each color through the LCD. Not unlike the ocean washing away footprints in the sand. Or getting rid of a static electricity charge by touching a doorknob.
Some LCD projectors have cheap polarizers in them, which can have a sort of burn effect after many hours of use. Some call this burn-in, but it is very different from CRT burn-in, and is only found with cheap materials. It is not specific images that are "burnt", but rather a hazy discoloration of the polarizer. The polarizer is a little piece of plastic that the light passes through (I think these give the color in a 3 LCD PJ), and it can be replaced if damaged in this way.

This is really only a problem with plasmas. A lot of plasma owners have a lot of issues with burn in, and a lot dont. I know i did. If you game, plasmas are far from the prefered type of tv, but i hear panasonics are better then others. Ever since i went with a front projector, i cannot even imagine in the SLIGHTEST dumping $$$ into anything else. Im playing xbox 360 on a 92" screen and using the PC at 1920x1080 on it, im tellin ya, its OUTSTANDING. And this is a 480p projector too.
