The costomer said the system Freez while he using it and he did a force shutdown. The problem started.

I hope you've checked with J9600 metal plate in place.
If the corresponding voltages from left side (reffered to schematic) are present, then J9600 has bad contacts.

just noticed u3100 is extremely hot, and board still draws 20V, and the processor is also pretty warmed up. I couldn't continue because the u3100 area was too hot. My question now is how can we have a bad CD3215 chip and board still draws 20V and processor still able to start up?? this is the very first time I'm see this!!!

Why do you bother with USB-C, once board is booted?
So dificult to find why voltages from left J9600 don't pass to right side???
How much time do you need to check them?
I bet U3100, or other chip don't have time to burn; if you do your job right.

BTW, U3100 stil gets hot, if you connect charger on other port?
