Pin 3 should be way lower...something around 4V.
Could you check continuity (diode mode) between
pins 4 and 1-2-5-6?
pins 3 and 4?
EDIT: With no power applied of course.
No beep at all on all the Pins you asked.... I should just go run this over with my SUV a few times, pick up the remains and burn them and then bury it.....
Just for the heck of it I replaced C9782 as well...
Ok you seem to have a break in the trace between pin 1 of R9731 and pin 1-2-5-6 of Q9706, so
Double check before and run a wire If no continuity, after that you should get around 3V at pin 2 of R9731 it's bkl_en.
Thank you for the suggestion, I didn't even notice the through the hole to other side was bad :-/
I have the 3v on pin 2 of R9731 still no backlight. I'm beginning to wonder if this board is just hopeless
