820-02443 14" M1 angle sensor / keyboard / trackpad not working

04-29-2023, 11:03 AM

FYI.
I just had a 14" M1 MacBook Pro with liquid damage very small pretty much only angle sensor sustained any corrosion or damage.

But both keyboard and trackpad will not work at all ! Screen would flicker on and off all the time.
I ended up re-building the traces on the angle sensor cable using very small copper wire... this fixed both the flickering and the keyboard / trackpad.

I'm like WTF does the angle sensor have to do with keyboard / trackpad ?

They are disabled when the machine thinks the lid is closed, which is what the lid angle sensor is for.

820-00426 (A1398 2015) no trackpad, no keyboard.

by nicocorradini

Hi! I have this 2015 A1398 with 820-00426 board that's driving me crazy. It originally came because of charging problems (MagSafe Board roasted, also MagSafe cable, etc. After disassembly, clean and assembly, my assistant (literally) broke FL803 and other componentes. Obviously, no screen or backlight. After replacing them, and also the LVDS connector, and LVDS flex on the screen, the board started fine, charges, chimes, shows Apple Logo, but surprise: no more trackpad or keyboard.

-Already tried with another trackpad,...
