Reparing Tesla Wall connector gen 2

[inquisitor]

Hi guys, does anyone have possibility to check outgoing voltage on tesla wallbox power supply pcb Board? my high frequency transformer is badly demaged/burned  on the primary side including demages on switsching transistor and some resistors ,it seems to have also some shorts on secondary side after apply  12V the Box starting the led light is green after rebooting showing me permanetely Red light on
probably is missing 5-6V on some parts

Hi,
I have a TWCgen2 with the same symptom: device is dead/no function, transformer TA1 has similar burn marks, however no other components seem to have been damaged.

Good News: when injecting 14V_dc & 3,3V_dc via CNA7 [PCB<-->LED-bar], the main PCB seems to work fine. It can "talk" to TWCmanager for example.

BTW: have you seen these topics on this very EEVblog forum ?

On my device TA1, the Delta SMPS Flyback Transformer, has the following markings:
   DELTA MP-130I
   AV-TP15010 (08)
   DCWM 1844(06)S6

Maybe, the nice people chez Myrra (https://myrra.com/flyback/) can help us out ?

Did you manage to repair the charger? I also have a defect gen2 and wonder if it can be repaired.
