I did the followings :
Measured PPBUS_G3H, PP3V3_G3H Are ok...
All right, My apologies; I should have checked with a new screen. I found a broken screen but showing backlight.
It Is amazing how the components communicate with each other.
I kept thinking was a board issue.
Thanks for everything.

The voltage is 5v and 0.05a to 0.08a slowly fluctuating.
PPBUS_AON is stable
3V8_AON is 0.200V going to 0.400V.
LC320 in diode mode is 0.009...
Hello, I received a job with a very damaged board 820 3023-A and I decided to replace it as they were too many issues.
After I have replaced the board I am unable to boot from the same hard drive that was in.
