Hi,

Got this board without any damage. Suddenly stopped working one side pf USB C (J3300) No V no Amps. Other side is getting 5.15V and 0.32 amps.


U3200... and this four components may cause this kind? Before this when it was CD issue i always was getting at least 5V on all ports.

Visual checking on logic board have no issue, nothing burnt.


Can T2 fail this way?

No rails found shorted to ground.


On J3300 when connect there is absolutly nothing on board, no voltage anyware.

T2 failure cannot cause different behaviour on USB-C ports.
There should be something wrong on affected area.

Check voltage and diode mode to ground on all LDO outputs of U3100/200.
