Hello, can someone with some experience help me with this PS4. I'm good with electronics, but without a schematic or board view cant find the fault. The board powers on 2 sec, so it's an power supply issue somewhere on the board. 12V come in, I can see 5V and 3.3V, but APU and RAM does not get powered on. On the thermal vision camera I can see for the 2 sec that it powers on an voltage regulator from 5V to 3.3V that powers the IR35211A controller that light up. The IR35211A controller get's power on VCC 3.3V and 1.8V on V18A pin, but nothing on EN and PWROK. I don't know the board and cant find any short on any power supply, also some work, some don't get enabled.
