I’m trying to repair an Xbox Series S. When I press the power button, I hear the beep sound and the LED turns on for a moment, but it immediately shuts off. The cooling fan doesn’t spin, and I also hear a “click” sound somewhere when the system powers down.
I found signs of corrosion in the area shown in the picture:
I was able to measure all main voltages: 12V, 3.3V, and 1.8V. Then I started looking for shorted to ground capacitors and found a few. I’ll show them in the following pictures:
(these are on the other side of the motherboard)
I also tried injecting 1.8V into the MOSFET area to see if anything heats up, but I still can’t find the faulty component. I don’t have a thermal camera.
Could you please advise what else I can try? Is there another area where I should inject voltage?
Let me know if you need more info, measurements, or pictures. I really appreciate your help—thanks in advance!
