For some very strange reason I can't get into the PS3 Main Menu. It goes completely blank, and it looks like there's no signal being sent to the TV. Games still work because it'll load up games, but when I "Quit Game" it goes completely blank again! This is really frustrating because I just got my ps3 last week!
Did you change video display settings recently? I'd think it might be that, but you say games are working fine so maybe not. Just a suggestion.
