hey i was looking for some help. I recently accidently broke my Xbox 360 slim, and has been stuck using my old xbox 360 arcade. It has been working fine til recently Ive got the "open tray error" my black ops will be in but it will still say open tray, Ive tried all my other games and it still dosent work. Ive tried the "Tapping" method, turning on and off or whatever. s*** dosent work. then i just put a dvd in, but it works? im thinking either my laser or something is dirty? or its just broke idk... But any ideas on how i can fix this before sending it in? Someone told me a dvd cleaner disc would work. Or spraying compressed or air duster into it?
