Why wont my disc draw stay closed
My disc draw keeps ejecting
Mid 2013 revision to the Xbox 360 line of game consoles, featuring 4 USB ports and built-in Wi-Fi connectivity.
It sounds like you have a calibration bug with the light sensor that controls the eject button. Try turning off all the lights in the room, and attempt to insert a disc again. If it is the light sensor, you should be able to insert and eject a game without it repeatedly ejecting. Let me know what happens, and we will go from there.
Note; Make sure you start with the system off, before you turn off the lights in the room.
