any idea whats wrong with it? i hadn't used my ps3 for a couple months then recently turned it on, updated and put in a blue ray movie and my ps3 acknowledges the movie, but it just went to a black screen when i selected it. The same thing happens with my killzone 2 and CoDWAW but nhl 09 will work sometimes, what is wrong with my ps3 and what would i need to do to fix it?
