No game works on my 360, its not because of any scratches. I just got Gta 5 and the install disc worked just fine, but it wont play the game disc. I have two 360s, one white and one black. The white one works just fine and the black one is the one that wont play games. They both look the same besides color. Its not just Gta 5 though, it wont play any other game I have. It was a used 360 and it was working when I got it. I'm looking for help on why it wont read any game.
