Yesterday, the kids dropped in GH3 to play and it started (according to my 18 year old) and he chose a song to play and then the machine locked up. When he turned it off and got it started again the PS3 won't recognize any discs at all, period. I've tried all our PS3 games, a netflix bluray, and DVD's. No joy. It doesn't recognize any disc at all. I'm assuming the drive has died. What do I do? Has anyone dealt with this before?
