We have inspected your PS4 system. There are problems with 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. Right now we do not have PS4 units for replacement options in stock, however we can offer other model units which we can discount for the trade in of your damaged system. As a final option, we can simply return back your unit to you and the inspection and diagnostics fee is $21.95.
