Hi all,
I have a macbook a1707 with a board 820-00281-a. The screen backlight does not work. I first replaced the capacitor after the d8410 diode. The voltage rose to 10-12v. , the backlight does not shine. There is still no voltage on ISIS_LCDBKLT_P, although there is a voltage of about 11 volts on ISIS_LCDBKLT_N.
Can you tell me how to solve this problem with the backlight.
I am attaching a photo with notes on the voltage at the backlight control area.
