    HI sir!! please a1398 coil short

    Hi Sir Thank you!

    I want to get help.
    I was working on a macbook a1398 repair.
    The cause is that it turns off during use and the cooler turns very quickly when booted.
    It doesn't turn on, but it keeps turning off like this.

    When I disassembled the main board and checked it with a tester, the other coils are ok
    Can you help me?

    I'm really grateful
    Thanks anyway!!
