What in the world could be wrong here? When I boot the machine cold everything is fine, but when computer is hot and LCD goes to sleep a strange thing happen when the sceen wakes up. He get discolord, like water had affected it.
Any thoughts?

I had this happen on a 2009 iMac. When I upgraded to a 2011 I got AppleCare and sure enough, round the one year point it had the same issue.
