EDM-041 2 sek. Blod 80810001

Hello everyone,I have a PS5 Slim that’s driving me crazy. The console starts briefly, the fan spins for a moment, and then it immediately shuts off again. UART error code 80810001.I have a short circuit of 2 ohms on the components (see picture). I resoldered the three components as well as the step-down converter, but unfortunately without success. I also removed the southbridge, but the short circuit is still present. I can’t find the cause using a thermal camera or isopropyl alcohol. Do you have any tips on what else I could check?

Where does this rail go?

Then I also noticed that there are no volts at fuse 3502 in standby mode.

Is F3502 open?

I’m measuring 12 volts input to the RA18 MOSFET, but no output in standby mode. The fuse has normal continuity. I’ve replaced the RA18, but there’s no change. Should there be voltage across the fuse in standby mode?

Don’t be alarmed, the yellow stuff on the spool is leftover tape.

At fuse F3502 line 5V_MAIN (for USB C and disc drive) is not present in standby.

Okay, then I was looking in the wrong place. But what could be causing the problem with the short circuit in the first picture of my post, where the coil and both capacitors have a resistance of 2 ohms and are shorted to ground?

At your first picture my readings are 2.5 kOhm resist / 250 mV diode. This line seems to be 1.8V_SOC_VDDA. It is connected to all GDDR6 RAM chips, XDPE and APU.

Should I remove the Infineon then? Otherwise, it’s probably an APU defect?!?

At this point I would inject 1V (not more) at the coil of your first picture and see with a thermal cam if one of the suspects gets warm/hot

I’ve already tried that, including using isopropanol in many places. Unfortunately, without success.

Can you post the whole UART error code string?

I can not find additional informations what is causing the 1.8V_SOC_VDDA line to stay low. Only APU is not responding and not turning on (213C = Main SoC Reset release; FFFF (in second last row) = APU temperatur: no value)

In the edm-020 schematics are two tiny caps on the backside of the APU and one tiny cap at the XDPE pin 19 VDDIO, which could ground the line if defect.


Thank you very much, I’ll check it this evening.

I removed the three capacitors. In the picture, I see ground contact on all four contacts. So, is the APU defective?

If I test caps or resistors I move them in most cases to one side to one pad. If removed completely they tend to go in the seventh dimesion and never seen again.

Still shorted to ground = the caps are not the issue.

A quick summary:

  • the source of line 1.8V_SOC_VDDA the chip on your first picture (TLV62090) and the both caps have been removed. The short was still there.
  • the three caps at the APU and XDPE chip on the 1.8V_SOC_VDDA are removed and the short is still there

I would remove the XDPE chip and check the line again.
If the short is not gone, the issue is at one of the GDDR6 RAM chips ot the APU

Xpde removed, problem persists. I’ll stop here. Thanks anyway for your support, @Calvin.

hey bro how are you?

so i have same problem same board edm-041

uart error codes

80810001

C00C0002

same thing going on my board. i cannot the find problem.

C00C0002 = VRM controller access error
The XDPE is not responding. I would check the resistance to ground reading at the XDPE chip at pin 55 (3.3V_VRM). It is the power supply line for the XDPE chip.

so bro i change xpda ic. there is have problem. there have 2 mosfets (12 v rail) on standby mode there are shorts i change them. so nothing was change . blue light one beep thats all.
