biggest cause of screen burn is having your contrast and brightness cranked up, iv had my plasma now over 7 years and have logged a lot of hours with GT5 and fallout 3 not noticed anything.
but if you do the same with a crt you will get screen burn eventually. its just takes a little longer on a crt.
