Hi there, just wondering if anyone out there who has a semi-working or working PS5 board could check the output voltage on F3501's buck converter for me, with and without power. I have 12V on the input, fuse not blown, no output voltage on that IC, with or without power, and no shorts present.
Symptom: 2 Second BLOD
Testing: All other rails seem present. APU, SSD, South Bridge, and RAM confirmed to be powering up using a thermal camera. Monitoring the current draw of the 12v rail shows a somewhat normal boot cycle of the south bridge. Jumps up to 300ma, and down to 0.
Any help is appreciated, thanks!
