Context:
I sent my switch oled for modchip installed. It was working fine for a few weeks. Then I am not able to charge. When I put the switch in dock, no video on TV and dock is blinking green light. I am super new at circuitry, any pointers would help.
Diagnosis:
The pin 4 and 9 for the usb port gives out 0 reading in diode mode:
My understanding is that those pins are linked in the VBUS. I looked up the bq24193 diagram and I am getting 0 readings for pin 1/24 either.
What are some other things I should check?
EDIT - It seems like I can’t post pictures nor links
