Hello, I'm working on an 820-3435 motherboard with no green light
pp3v42 circuit was heavily corroded, some VIAs were destroyed. All corroded components replaced, jumpers ran to repair damaged traces
I occasionally get an orange light (never green), but in the rare instances I get it it disappears soon after
PPDCIN_G3H is 15.11v (measured on R7012)
DCIN_ISOL_GATE_R is 14.88v (Measured on C7012)
PPDCIN_G3H_ISOL is 0v
Replaced Q7010, no change
PPBUS_G3H is 0v
PPVRTC_G3H is 0V
PPBUS_G3H was originally dead shorted to ground, hooked up a bench power supply at 1v to inject voltage, as soon as I turned it on the short disappeared. It was quick enough for the power supply to not show an amp draw, but limit was 2A
