Hello guys, i got this Ps5 with 1 second blod is my first time working on this board and i would like some help finding what's wrong.
Things i did:
1- Checked standby voltages , seems all present ( dunno if im missing some test point )
2- i read Uart code and gives me this :
[Slot #] [Date Time] [Error Code] [Priority] [Error Message]00
25/04/2025 21:53:01 80810001 Severe PowerSequence - Power Sequence Error - General Power Failure (Peripheral, GDDR6, APU, Data Line Short) |-(OK 00000000 80810001 FFFFFFFF FFFF0023 10000100 213C 0016 FFFF 17C0:EE) Click for TSB Information01
25/04/2025 21:53:01 C0020303 Low APU Not Responding - Trying Init or Reboot - 3 - (User Submitted: System wont start Blue Light Flashes), Check Fuses F3501, F7501 |-(OK 00000000 C0020303 FFFFFFFF FFFF0023 10000100 213C 0016 FFFF 17C0:F7) Click for TSB Information02

Couldn't find any short, around the only area that beeps with tester are the single coil collocated on the left side of the apu and 2 lines near the infineon chip, that goes straight to the apu. ( i think is just low impedance)
3: i took a look with my thermal cam to see if something gets hot while powering on, ssd controller , ram , southbridge gets hot like they should do no hot spot at all, apu doesn't get even warm but 1V rail is present at the coils while powering the console.
don't know what to check i feel like im missing something very simple.
i would appreciate some help finding the problem that is causing this blod issue.
Thanks to everyone that will take some time to answer
p.s: english is not my best, but i hope everything is readable
