No signs of liquid damage on the board. All voltages on backlight circuit look normal but still no backlight. I have narrowed it down to it being EDP_BKLT_EN, and EDP_PANEL_PWR.
Both of those are at 0V.
EDP_PANEL_PWR pulses on start, goes to about 5V for half a second, then to 0V.
EDP_BKLT_EN does not pulse, but is at 0V.
I dont know if this is relevant but SMC LID is always at 3V42V, I dont know if these relate to each other.
EDIT: System does power on and boots, chimes, and shows image
