We have inspected your xBox 360 unit. There are problems with the internal data bus for the sata dvd drive in the unit. The total cost for repairing the failure, full disassembly, cleaning with in store pickup is $64.95. The way that Microsoft designed the system, total replacement of the main board and drive electronics unit is extremely difficult since the DVD drive is ‘keyed’ to the motherboard and this is why we are repairing the unit rather than major section replacements. As an alternative, we can return back your unit to you. The cost for inspection and diagnostics is $26.95. Please make payment below to proceed.
