Do you have the same voltages on pins 21/22/23 of M92T36 since you changed it

What voltage do you have on pin 28 of M92T36 with the charger connected, can you test this pin for a short to ground aswell.

yes, sames values as before.

Pin 28 : 0.4V / 2MegOhms (not shorted)

Just noticed the shoke near the fuse at the USBC area was shorted
After replacement nothing has changed.

If your talking about the choke on the D+ D- lines this should have continuity

Just above the M92T36 is a dual P channel mosfet (6 pin) can you test what voltage you have on pin1 with the charger connected
