the other poster already replied to what you are experaincing with your lcd, but i think it is a good idea to post that this is an issue for just about every form of display. how much and how often it affects you is based on your display type, how often you use it and what you display on it.
if you have a plasma, this is called image retention. it is not burn in as it has not actually "burnt/damaged" anything, it has simpley trained the phosphors into showing whatever color it was showing for as long as it was and not the others. to get rid of this you will need to "recharge" the phosphors where the pixels are having the issue, basically they just need to be rest if you will. Switching content to anything the rapidly changes the pixels colors around (the brighter the better) should resolve this in time.
how long it takes to go away depends on how bad your image retention was.
Although burn in is somewhat a thing of the past now, image retention is here to stay. if your set has anti image retention functions (pixel orbiter/pixel shifter) in its menu and you plan on gaming a lot turn up the fequency of the settings to run every 5 minutes instead of there default values which are typically set for film content that isnt as demanding or as high in contrast.
