Hello! So I have two PS4 pro, both are not turning on. One is a nvg 001 with PSU adp-300FR and the other one is a nva-001, it has no PSU. The nvg-001 beeps 3 times in a row and then turns off, so I wanted to check the other one but as far as I could investigate, its pinout on the 4 pin connector is different.
So what I did, based on what I could find, is swapped the cables from the PSU, the GND and the ACDC_STBY (I found its pins are 1-5v, 2-ACDC_STBY, 3-GND, 4-5v) so I could use it on the nva-001 but still, this one does not even beep or anything. Weird thing is that the PSU does not have any voltages as soon as I plug in the 4 pin connected with the motherboard, it shows 0 voltages on any of the two 5 volts pins. What could be causing this problem? Just to clarify I am a beginner which is trying to learn, I have these PS4 pro from a friend who gave them to me to see if I managed to fix at least one of them. Any help will be appreciated!
