So I have bought a dropped PS5 very cheap, I plug the power and I get 1 beep no light, the liquid metal didn’t escaped, I did a UART diag with consolerepair tool and this is what I’m getting(the motherboard is EDM-033)
[Slot #] [Date Time] [Error Code] [Priority] [Error Message]

What I have tried so far
- i have checked F7001 and F7002 fuses
- i have checked for shorts around WiFi IC
- I have found online an almost similar board(see the attached images) and checked the voltages for NUVOTON HDMI IC and
5V STBY is present
3V3 STBY is present
0.9V PWR(when I press the power button) is missing
1V8 PWR is missing when I press the power button and also there’s no short
On SSD Controller everything is fine when I press the power button
5V is always present there
and the rest of my noted voltages are coming up for 10 seconds there but then 0
What else should I try? This error is driving me insane
