Charges with only 1 CC Port. (Using 820-02016 Schematics)

UF400 corresponding port wont charge. UF400 visibly burned.
Replaced UF400 and UF500 Both. Still the same.

When doing thermal scanning and plugged in on UF500 corresponding port - a Coil and a 8 Pin ic heating up. The same flashes when UF400 is plugged in. (Image attached).

Due to lack of schematics i cannot move further. There is no short on any pin .
UF000 below the shield also heats up.

I cannot find the 8 Pin component anywhere on 820-02016 board.
