Same problem for both PS2 games and playing DVDs on the PS3 (60GB fat, one of the first models released).
The game/video will play fine and randomly the screen will go black for a few seconds (audio continues fine) and then reverts back to normal as if nothing happened.
This wouldn't be so irritating if it wasn't happening every 10-15 minutes. Does anyone know a solution for this problem?
Thanks very much for your time.
