Wait wait, but the Southbridge needs to initialise the XDPE Chip before starting, right? So there has to be a short voltage peak when u plug in the console, in my opinon?
So then maybe Southbridge is broken?
I need to check this, but my time is very limited at the moment due to Work and Famaly/Kids.
When everything is short, your Dialog should be the Problem. Can you inject voltage? 1 Volt on a shortet Line an Look with thermal camera?
Thanks for Sharing your files, i think we all know this 
Problem is i measure before it is not short before. just now it is doing that. ) i cause a problem maybe ) so i dont know. ( i have another funny problem with other ps5. i gonna be share that problem also. )
Remember, you can’t measure resistance when voltage is applied
When i inject voltage 3.3V to Pin 3, Output 3.3V is pressent.
When pressing the Power Button, 3.3_vrm ist present for a split second.
I try chancing the xdpe chip
Same Problem after replacing XDPE Chip.
As i see it, southbride needs to initialize during startup phase (standby voltage) but it’s not doing that. It’s stuck at about 30mA
What is the resistance reading at pin 19 at the XDPE chip? (1.8_SOC_VDDA line)
It is 29ohm. To Low, right?
I would expect kOhm. There are some caps I would check at the line. The top red square is the source chip from the 1.8V.
On my Board, as you can See also EDM-041 the source is different, maybe that’s why the measurments are different?
I removed all marked caps and also the main coil. Now it is 10 Ohms 
So we are coming closer. Tomorrow i will inject voltage again. I now think it’s a RAM problem.
Ahrrr… 30 ohms again, i don’t know. Board wasn’t hot while measuring.
I will remove ram chips tomorrow.
Hello everyone,
I once again have a PS5 Slim EDM041 that is driving me crazy. These units are a disaster.
This console is completely dead — no beep, no reaction when pressing the power button, and no response from the disc drive button either.
I have already replaced the Southbridge, but there was no change.
The only thing I noticed in this area is that the top two pins have 12V input, while all the other pins show 0V in standby voltage.
The circled capacitor is currently removed; it measured 0.02 ohms.
In the second picture, the top capacitor measures 0.10 ohms and the bottom one measures 0.20 ohms. Is that normal?
Power sequence on the bench power supply: 0.003 A.
UART reading not possible.
@Eckard44 Your readings are fine.
What is your reading at fuse F7001?
7001 5,14 Volt
7003 5,14 Volt
It seems that all outputs are present. With the southbridge changed and still not responding at all I guess someone messed with the BIOS.
Can you dump the BIOS and check the dump?
Unfortunately, I can’t do it without that. But I don’t think it’s the BIOS. The previous owner said it suddenly stopped turning on.
