When i put in a disc, sometimes the tray will just open right back up. When i get it to stay closed, i dont hear the discs spinning, i just hear a faint clicking noise coming from inside the disc drive and on the screen it will just say "open tray". I have an old school white system and the last thing i want to do is pay for a 250 GB console and transfer wire when im trying to save up for an xbox one......any idea how to fix this or suggestions? I tried using a lens cleaner disc which basically did nothing. Bah!
