Hello. Got this board here with a strange issue. It partially turns on(some S0 state voltages are present). No fan spin. I have DDR voltage stable ate 1.2V, but PP5V_S4 is measuring low, at only 3.05V. Tried replacing TPS51980 and MOSFET, still same. Something is dragging 5V voltage down, some kind of leakage, but nothing gets warm. Board had no corrosion at all, everything looks pristine. Any tips on how to solve this?
