This board looked very clean. There was corrosion on J3500 pin 16 but no where else. I used the USC anyway but I couldn't see any other issues.
I'm not sure where to find the course of the PP5V_S0 but after looking and looking It seems to come from U9500.
There is no 5v coming from here.
No PP5V_S0 from u9500
Pin 19 VSS is 0v
Pin 3 VCC is 3.6v not 5v
Pin 5 Vref3 is 3.2v not 5v
How do I identify the switch to turn on pin 19?
Any other ideas as to what my issue might be? I have looked at many videos but they all seem to end in finding a corroded area and replacing the component. I don't have any obvious bad components.
Thank you
