Getting really frustrated by this board and I need someone smarter than me to explain what is going on.
When I got the board it was water damaged but started with RAM beeping.
I found that there was no PPDDR_S3_REG voltage, and there was a short on the rail.
I have now replaced every capacitor around Q7330 and Q7335.
When I take of Q7335 the short to ground is gone. I have replaced Q7335 four times now
The short is worse when the board is warm, 0,010V in diode mode and slowly gets to around 0,100V when somewhat cooled.
When I take Q7335 off the board it immediately measures 0,370V
The donor boards measures 0,370V before I take the Q7335 off.
If anyone have any idea what's going on here please tell me.
