We have inspected your xBox 360 slim system. There are problems with the internal memory electronics in the system which needs to be replaced. Dust can be a failure point, in addition to moving the unit when it is warm, so 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. The total cost for replacing the memory electronics, cleaning the unit and return shipping is $82.95. That includes a 90 day warranty on the parts and labor. As an alternative, we can ship back your unit to you. The cost for inspection and return shipping is $24.95. Please make payment below to proceed.
