A1706 820-00239 which had extensive liquid damage.
Located and removed the short on PPBUS_G3H. Now turns on, charging and works fine. Passes Apple Diagnostic. The only issue seems to be not USB and HDMI output via either of USBCs. No light on a USB drive.
Tried SMC reset. Another strange thing is when I do a PRAM reset, I can see the screen flashing for it, but no chime sound. Can't remember if this one had a chime sound or not.
Haven't worked on USB/Video via USBC's before. Where do I look first?
