      I’m troubleshooting this board that shows no signs of power when the PSU is powered on (no fan spin, no beeps, no LED lights). The mosfets near the 24-pin seem fine, and then I checked the SIO (Nuvoton NCT6798D) and found a short to ground in pin#106 which is a 1v ASVB line. My question is, does this mean the SIO is bad or could a cap or other component along that 1v trace cause the ground? In the research I’ve done, these SIO’s seem to experience catastrophic failure when they go bad, not a single pin.
