I’ve read a few posts on here about users with their XBOX One X’s turning on and then immediately turning off. It seems that it could be the APU or southbridge as I don’t seem to have a short anywhere.
I bought this XBOX knowing it was bad, but I wanted to try my hand at fixing it. I started by going over the board and looking for the obvious, corrosion, burned chips, or bloated capacitors. The board itself is in pristine condition. The seller said the XBOX was working fine until it was knocked off their entertainment center. I did find some broken plastic bits while taking it apart, but curious how to narrow down the issue to either the southbridge or APU?
Ive checked voltages and am getting 11.6 volts dc everywhere it should be. The test points on the top of the board show a power spike of a few volts during power on, but 0v normally. The fan never starts spinning, but i’ve tested the fan and know that it is good.
I just tried to upload the pictures and am unable to. Will try to generate some links for them. I have some high-res pics of the board.
Has anyone successfully done a DIY reball for the APU or Southbridge?
