Hi again.
I get 20 volts to F3001 when connected to the outer USBC port on J3300.
The trackpad clicks, so the unit is turning on, but there is no display.
The power button will turn the unit on and off - i.e. the clicking will stop, or start, again.
There is no signs of any liquid ingress to either side of the logic board.
I've tried with an external monitor with the internal screen disconnected, using a known-good USBC-HDMI adapter.
I've also tried with a known-good panel.
Not familiar with this board.
Any help appreciated as to where to start this one.
PPDCIN_G3H = 20.30v
PPBUS_G3H = 12.57v
PP3V3_G3H = 3.36v
PP5V_G3S = 5.14v
