PS5 EDM-033 UART 80810001 Beep 1 second Ligth

[Egidio85]

Hi everyone, I have a ps5 EDM-033 that beeps, blue light for 1 second and turns off.

reading the error codes via uart gives the following code:

80810001 General power failure (periphery, GDDR6, APU, data line shorted)

checking the card I didn't find any shorts, Boot sequence is quite right 325 mA dropping to 9 mA.

Using the thermal camera I can see the SSD controller and South bridge getting warm.

if I press the power button the RAM also heats up, the processor doesn't seem to. in fact if I go to measure I don't have +1v CORE output.

any advice on what i can check ?

thanks in advance
