820-00281: No booting up but CPU/GPU warm with fan spinning.

I have this board, customer said it wasn't getting image to the display but did get image on external display. Once i started working on it, i noticed there was no usb-c activity on any of the port, which also meant no external display image. Started probing and noticed L7410 and L7421 (PPVCCGT_S0_CPU) were reading 0v.

Signals to U7410/U7420
PP5V_S0 - 5v
CPUGT_FCCM - 0.015
CPUGT_PWM1 - 2.57
CPUGT_PWM2 - 2.58

current pull by the board swings inconsistently between 1.20 and .91A

Any suggestions?
