3 All USB-C ports functional, except for back left which only draws 5V
Curious to know if anyone can help me diagnose this issue. Three of the USB-C ports draw the correct voltage (around 20V) and can be used to power on and charge the device, but the back left USB-C port is only drawing 5V. I've replaced the USB-C board multiple times but the issue persists even with a new USB-C board installed, indicating a logic board issue. In my experience when there is a fault with the USB-C controller chips on the logic board it causes all the ports to draw 5V. Anybody have any recommendations or tips for diagnosing this issue? Thank you!

@zpl you have checked the port controllers and they checked out ok? Anything "weird" on the connector?

Nothing strange with the USB-C board as far as I can tell (and I've tried it with 2 new USB-C boards and got the same issue). I think this is a logic board issue, but I don't know where to start to diagnose which components on the board are faulty. Normally I would suspect the port controller chips, but I've never seen a situation where only one port is stuck at 5V but the other ports work fine and the system is able to boot. Thanks!
