There's nothing you can do. Even Best Buy's protection plans offer panel replacement only if you have 5 or more dead pixels in an inch. It sucks but you'll just have to deal with it.
I've had a bit of an odd issue lately with my panel. During certain black to grey screens/scenes I'm getting flickering green spots all over the screen ranging from small (a few pixels) to larger ones that are bigger than the size of a quarter. I can't duplicate it either. It just happens randomly. Any one had this issue?
