Plasmas do burn in but lcd's can also suffer the same thing with static images, though it takes longer.

Ive had 3 lcd' monitors so far and only 1 dead pixel which isn't even noticable as its in the bottom right of the screen where windows displays the clock. Far as im aware if your lcd arrives with none its unlikely to get any as its usually something that hapens when the screen gets manufactured.
