PS5 EDM-033 Only beeps, doesn't power up
I have been trying to fix a PS5 motherboard, EDM-033 that only beeps when you press the power button. Beeps once. No lights. What I know:
- Error code in UART: OK 00000000 80810001 1ABCDDFC FFFF0023 10080000 216D 0036 FFFF 19AA:E4 (80810001SeverePowerSequence - Power Sequence Error - General Power Failure (Peripheral, GDDR6, APU, Data Line Short))
- All fuses seem to be intact.
- I can't find any caps that are shorted until I get to the bottom of the APU. Then I can find a bunch that are shorted. This is because they all connect back to the same plane I guess. Meaning, I can't determine with caps are the problem until I pull them. Or...
- I hooked up my bench power supply to F7102 fuse and tried to inject 1 volt and 3 amps. I was planning on using my thermal camera to spot the cap. However, that didn't work. The bench power supply can't hold CC mode. I tried all the tricks to get it to hold, but it immediately backs off down to 0 amps.
Are the caps I took pictures of looking bad to anyone?
