The tray of my Xbox 360 slim rgh opens and closes many times alone, and for no reason. This even if the console is turned off. It is very annoying because it opens even though it is turned off and therefore turns on. Other than that if I'm playing take me out of the games.

friend the tray is not closing properly so it opens and closes alone, this is mostly due to a rubber pulley (belt) that wears out and gets bigger, so the engine to open and close the tray does not it reaches to move the mechanism that controls the unit well, remember that said unit has three motors, one that controls the laser, another controls the rotation of the DVD and finally the one that controls the tray to open / close
