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

Are there more error codes and do you have the complete error string?

Thanks for your interest, not only this error code. I attach a photo
sorry for the quality of the photo, I took it like this as a reminder

Ok. All error codes are the same. The seqence number at the error is 216D and it means that the SoC isn't powering on.
Maybe a replacement of the ssd controller helps or a reball of the SoC.

I'm not a friend of reflowing. I would replace the ssd controller and check if the issue is the same or not.
 
I am having a similar issue but with slightly different logs. When the device is left unplugged for long enough, I get the one second light before it cuts. I am able to get it to work if I unplug the device and plug it back in not long after. I haven't figured out what exactly is the cause yet but I was curious if you were have the same experience.

Here are the logs I have:

I'm not a friend of reflowing. I would replace the ssd controller and check if the issue is the same or not.
checking carefully I noticed that some voltages standby are missing in the hdmi circuit, I have already tried to change the panasonic chip

those circled are not present.

Could be a major change in this ciruit at the edm-03x boards. But from my previous messurements as shown in the image, the 1.8V are not present in standby and are not switched on by the southbridge before 'Start'-button is pressed.

Hi, how you know 216D is mean that? Where I can find this?

Hi could you help please.I have the same 80810001 but the prefix is 213C what does it mean?

Thank you in advance.
 
I have the same error code, same motherboard. I can also get it to boot if I attach a ch341a clip to the bios / nor and read it's contents and save the file to my desktop. It boots to a white light after that. The next day it will go back to a blue light and powers off. I attached the clip again to the bios and deleted it's contents. I downloaded a fresh copy of the bios / nor for 1215A. Used thecod3rs nor modifier to change the serial number to match mine. Wrote to the bios / nor fine. It booted up and I did a reset to bring it back to defaults. Installed updates. Then I shutdown the console. The next day I tried to power it on and it went back to a blue light and powers off. I am thinking I need to replace the bios /nor chip. I already replaced the cmos battery.

Hi, were you able to fix it?
 
The southbridge was dumped and decoded. Based on the finding the meaning behind the codes are discovered.
Dony has a tool, which decode the whole UART error string and give plane text: https://github.com/apewalkers/Dony-Tools-Gui
Hi All,

This is now a 404 - anyone know where I can find the dumped Southbridge codes?

This is now a 404 unfortunatley. Anyone know where I can find the Southbridge dump with codes?
