Hello everybody!
Have in work A1706 820-00239 model. Originally no power, shorted PPBUS_G3H because of corroded C6403, C6404. Some water damage around this components, but nothing major.
After replacing this capacitors the laptop came back to work, I reinstalled MacOS and had no issues until I started to test Type-C ports. Sometimes the laptop shuts off immediately when some action with Type-C ports performed (charger disconnected or USB device inserted/disconnected). I checked Type-C port flexes, they are okay, but I cleaned them anyway. I can't see any signs of liquid damage or corrosion near CD3215s (these have underfill on this board, so no corrosion underneath).
As it is intermittent issue (like the laptop shuts off in 1 of 10-20 times), I don't know where to look at. Do you have any suggestions?
