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.
Important notes:
-Click works, so, trackpad is alive.
-Already tried with another trackpad, another flex and another keyboard. Same result.
-Power button works just fine, even SMC Reset works.
-Them doesn't work in bootpicker menu, can't reset PRAM, open boot selector, etc.
-No corrosion, broken traces, etc in trackpad / keyboard related areas, everything is clean.
Really don't know what to do next. And client is really angry... Any ideas? Thank you in advance!
