Hello, I have an 820-00928. Board came in initially with corrosion on U6500 and U6550. Replaced those, have replaced U7000 and Q7030, and Q7040 (due to PPBUS_G3H low). No shorts on PPBUS_G3H.
PPBUS_G3H is 0.75 V and slowly increases. It's weird because it will keep increasing if I leave the probes on the board.
SMBUS_SMC_5_G3H_SDA-3.29V
SMBUS_SMC_5_G3H_SCL - 3.27V
I have measured all inputs to U7000 and they all seem to be the correct voltages. I'm running out of ideas.
