    Macbook air a1369 emc2469 boot issues

    Got a macbook air that fails to boot from any drive be it external or internal. It just shuts down when the progress bar is about 25%. After it's off i can turn it on normally with the power button. I tried flashing a clean ME efi but there wasnt any difference. What could be the issue here? I can take measurements on the board if needed. There is a bit of liquid damage on the back of the board. I uploaded it to the drive folder. And also here's the video footage. https://drive.google.com/drive/folde...DzIb6YHjc9RMvh

      cleaned with alcohol and no difference. Do you think a solder reflow would help?

        Try booting in safe mode.

          Safe mode booted fine with the screen blacking out constantly. Then I disconnected the ribbon cables one by one and after disconnecting keyboard it booted just fine! Lmao thanks for the replies!
