Very good voltage mapping, It can help me on troubleshooting on a PS4 I have issue with.

It does not show any sign of power on the main board, but the power supply is good.

I have checked few fuses (signed as Fxxxx on the board) but all had continuity.

I wonder if you can provide further insight if there are more "hidden" fuses or should I check something else?

The PS4 (model 1004) was working fine, got unplugged to be transferred in another room, and since then, not beep, no light, nothing.. dead.

Your schematics are for SAB and mine is SAA, but is 99% similar, so I gave it a go to test the power traces.

I can locate 2V, 3.3V and 5V traces on the board when the power supply is hooked on it but the touch sensitive power button does not respond.

I cannot locate any component to have 12V.
Why I cannot trace 12V, not even on the power supply's two rods?
Why the power button does nothing when I touch it?

I am sure something is blown but what???

Note: I have noticed that the two power rods on the board are have continuity from within the board layers. Is it normal? I must open another PS4 to check.
