Hi there,
Tried to condense the problem in the title. Hope it was appealing for someone.
I bought a broken PS5 with 2 sek. BLOD. When it arrived I noticed the bad condition of the console housing, bent cooler pipes and deformed disk drive. Yeah , obviously very bad drop damage. And obviously not appropriately described in the offer. Because it was my first hand on a PS5 for an okayish price, I decided to take the risk.
It is an EDM-020 CFI-1116A.
First thing I noticed was wrong initialization amperage. It went to 450 mA an then dropped to around 150 mA. Figured it was the WiFi chip, that was kind of shorted. After replacing it, amps were correct (300 to 9). But still 2 sec blod.
Second thing I found was a non initializing RAM chip. I figured this using a thermal cam on boot. Reflowing wasn't successful but reballing did the trick.
Finally the console booted into safe mode. When trying to restore the console I got an error translating to disk drive not recognized.
So I disassembled this as well. No obvious damage. But hooks on the data cable from MB were quite worn. So first I resoldered some suspicious connector pins on the BD PCB and then carefully aligned the data cable.
Now I'm at the stage were the console boots into safe mode. When trying to restore the FW, it stops at "1 sec remaining" on download. It doesn't react to controller input or power button presses at this stage. Kind of stuck. When I try to hard reset by pulling the AC-cable, the console appears to be completely dead. No beep, no light. After some time.it again boots into safe mode, stuck at the same time on restoring and than ... Dead. Reproducible behavior.
So this brings me to your immense knowledge. I highly suspect a bad solder joint on the south bridge, which looses contact when the board is at a certain temperature. Do you support this assumption or do you have a different suggestion?
Would love to see this device come alive again :-).
