820-01700-A, 1st (top left) usb-c port is dead

[djab203]

820-01700-A has no issues other than the 1st (top left) USB-C port is dead. The other 3 ports work fine. I've checked the entire board, and there is no liquid damage. All ports are clean. I've tried a new port, and still, nothing shows on the ampmeter. Please help!

First of all, welcome to the forum!

Check diode mode to ground on CC1/2 lines corresponding to that port.
Compare readings with any other port.
