We have inspected your xBox 360 system. There are problems with the optics, laser assembly, chassis, tray switch, spindle motor and gear loading assembly in the DVD drive. Dust is usually the #1 reason for failed system optics and burnout. We recommend using your discs in a disc case and do not insert them into the console if they are dusty. Clean with dust free cloths to keep dust to a minimum in and around the system. Do not use discs which appear warped, and never move the unit when operating. In addition our technician found quite a lot of dust on the motherboard and also in the fans. This needs to be thoroughly cleaned out or you run the risk of shorting a component on the board. The total cost for replacing the full 360 DVD-ROM drive assembly, new optics, resetting to the proper alignment, cleaning the unit and return shipping is $92.95. That includes a 90 day warranty on the Drive repairs. As an alternative, we can ship back your unit to you. The cost for inspection and return shipping is $29.95.
