PS5 shorted 12v Rail

Hello have a EDM-20 that has a short on the 12v rail. I have used a thermal camera and only sent 2v and its pulling about 5amps, the only place I see that gets heated up is the APU area, before putting in allot of time into this board would one assume that the APU has been shorted out or possibly a 12v line that runs under that layer that is showing that to be the heated area?

Any input would be greatly appreciated.

After further testing and reading online the APU has been shorted out.
