PS5 Single Beep BLOD UART Code unknown

[FiXiNGA]

Hi,

I have a PS5 on my bench with single beep BLOD. It flashes blue light for around 3s and then goes off. Second try is beep only (Init phase only). Then third again 3s.

All fuses are good. Init phase is 311mA then 7mA. Good so far.

Thermal cam Shows every relevant component flashes warm and then shut off. RAM, CPU, SSD Controller, Rail Mosfets.

UART is Not helpful, After clean and test only one error:

00 30.10.2024 20:47:08 80801610 High Not found in list. Report Findings.

So nothing i can deal with. Any ideas?

Thanks and Best regards!

No changes after swap or replacement of GDDR6 RAM #5?

I made some other repairs before but today came back to it.

After swapping RAM#5 with a donor one the console came back to life!!

Thank you so much, I do Not know on how to have this been documented in the UART lists. I m using CST and dont know where the descriptions of failures are stored.

Hopefully anyone is able to update the lists.
