Hello,
i was working on a console that has the blue light of death. Previous owner stated that it kept overheating on him. He took it apart and ripped one of the fan cables out of the socket(fan side. No visible mobo damage) and put it back together. It kept overheating. He said someone stepped on it at one point and then he started having the BLOD symptom. As far as im aware, nobody has tried to work on this console or diagnosed anything on it. Once i opened it, i did notice that fan wire ripped out of the fan connector as well as a big oxidation spot on the APU.
I am no expert on working on PS5 motherboards but i am trying to learn
Findings:
- standby voltage is present (as far as i can tell)
- power supply outputs 12V.
- No blown fuses that I can find.
- UART shows code 80810001 general power failure for all error logs. Same code shows back up when erasing codes and doing another power cycle on console
- No caps i can find shorted to ground
What would be the next best place to look or recheck? I was thinking of buying a south bridge replacement. i wanted to recheck the caps near the south bridge encoder first to ensure no shorts first. I was also thinking of reflowing the south bridge before buying a replacement just to see if that changes anything. I also saw some people post similar issues but they replaced the HDMI encoder/looked in that area and sometimes that fixed their issue. Any guidance would be appreciated
