We have inspected your PS3 system. During our diagnostics process we have found repair options for the USB ports which were damaged by physical issues which damaged the electronics of the main motherboard. We have corrected this issue, but have found the additional damage to the blu ray drive electronics to be severe and not repairable. There are problems with the drive electronics in addition to major components on the motherboard which cannot be repaired. The motherboard needs to be replaced along with the DVD drive. The way that Sony designed the system, they need to be replaced as a set since the DVD drive is keyed to the motherboard. The replacement set would need to come from a working system, and to avoid the additional labor required to replace all parts we would just sell you the replacement unit with the damaged trade in. We have a replacement which we can have allocated from inventory for your order. Replacement units with the damaged trade in start at $167 and go up depending on model and features or accessories. As an alternative we can return back your unit to you with the USB repair and the cost for the repair, diagnostics, inspection and return fee is $49.95.
