I've got an 13-ac023dx usb c logicboard Dax31mb1aa0 rev a ( Quanta X31 kbl-u 2016.08.05 )
clean board. both tvs diodes ( D36 & D43 ) were shorted. Removed
no other shorts on first glance. I have the schematic but no boardview.
The four vbus or vin mosfets around the two usbc controllers seem ok. no short among their B G D and also not to GND
Ports are good I guess.
usbc ampmeter shows 20V and only 0.03a. board is cycling every 3-4 seconds and the led flashes 3 times if I hit the power button
any ideas how to proceed on this one ?
best regards,
