820-4924 no image no backlight.
History:
Liquid damage, Backlight circuit repaired.
Machine is powering:
Machine chimes.
CPU gets hot.
External monitor works but cuts on and off... some sort of detection issue presumed...?
Tested with know working LCD eDP screen with joy = 0
eDP Pins voltages
Backlight circuit working:
Pin 1 = 49V
Pin 3 & 4 I2C_BKLT = Data both pins
Pin 5 - 3v3
Pin 8 = PWM
Any suggestions on what I should be checking instead?
EDIT: Pin 30, 29, 28 = 5V
