Re: Macbook pro Mid 2012 820-3115 No Backlight Has picture.
Hello Good Day, I'm Not Sure If im lae to respond here or you have solved your Problem For backlight On Your 820-5115 Board. But i wanted you to check if there is continuity between A5 of U9701 and {pin 2 } of D9701, if there is continuity the feedback line is working fine then the Problem might be your Backlight Driver.
if there is no continuity make sure to run a jumper wire between A5 of U9701 and pin 2 of D9701 it will fix your Problem...

Re: apple macbook a1398 15" retina (820-00426-A)
i believe that will be written on the motherboard itself so you just have to open up your mac and check the number that starts with [B]820-[/B]Re: apple macbook a1398 15" retina (820-00426-A)

Macbook Air A1466 820-3437-B No Power, no green light
Hello Everyone the board was water damaged and switched off
so i tried to clean it with 99% spirit when it switched off.
after that i tried to switch it on and what it did was it boot then off, boot then off then eventually boots at the third attempt.
so i removed the motherboard and i then did a mild reflow on the SMC (U5000) AND Then when i tried to switch it on then nothing happens, up to now nothing is happening
VOLTAGES:
PPBUS_G3H = 8.20V
PP3V42_G3H = 3.42V
PPVRTC_G3H = 3.3V
PP5V_S5 = 0V
PP5V_S4RS3...
