This is an interesiting Case:
I2C lines are fine
feedback is fine
sense cuircuit had broken traces (to the shunt resistor)
made those connections again
the screen is working. I tested it
on the backlight output i have 11.7V
i have found out that if i measure r7702 on pin 2 (with a multimeter) the backlight starts working. So i changed R7702. But still the same issue.
I have also changed the following parts: u7700, D7710, Q7701, R7701, C7700, Q7700
i am a little lost. What could be the issue here.
