820-01521 Has 20V but not turning on.

[bjf]

I removed a short on PPVIN_G3H_P5VG3S (shorted C7661) and was getting 20V but no current. Found another short on PP5V_G3S. It was a shorted U8110. Replaced. Still only 20V with no current. I can't find any other shorts and never witnessed one on the CPU. Any thoughts on where to get next with something like this?

Do you get 3V3_G3H and PPBUS_G3H?
If yes, think about T2 firmware issue.
