- We were measuring 55V at backlight output, which suggests there’s no load , we checked every related section of the board, but couldn’t find a cause , a friend then suggested a DFU restore and that fixed the issue.
thanks for this vidoes i learned a lot.. i am current fixing a macbook 820-01041.. mosfet is not open no 12v on the output..
No backlight repairs? What do you have on your diode mode on the backlight output?
