Its been warm today. Realised parents left tv on but before I turned it off I noticed how hot it was and touched the screen in places as it was really hot. I turned it off and a lighter black or grey remained where I touched it. You can hardly see when watching but if a dark bit comes on you can. I left it on now, man I'm in trouble. I hope it goes away... Anyone got any suggestions. They will be a bit late but I can at least say I've asked if it can be fixed.
