I have a PS5 that does not powerup, I have the 12 V rails in the appropriate places but no 5V or 3.3V in all the areas they are supposed to be in. I was wondering if anyone knew where the 5V rail is generated from, which section of the board?
I checked voltages at the 1R0 and there is no 5v present. I checked for shorts on the two mosfets
and there is no presence of shorts. is it possible that the mosfets are the issue. I do not see any voltage on the gate side of the mosfet.
