    Macbook Air A1466 EMC 3178 missing power and liquid damaged

    Hi everyone.
    Macbook Air A1466 EMC 3178 (board 820-00165 A) not turning on and no charging light. Completely dead. With no battery connected it would power up and I could hear the chime, but nothing on the screen and then a sudden turn off. Sometimes during the chime. Opened it up and found some liquid damage. The flat that connects both boards has damage in one side (with a missing pin already). The connectors on the boards are fine, though.
    Also, there was liquid damage on the included picture area, which are R8111 and C8111. A quick and soft brush on it made the resistor be gone. Cap is not the best, but does not seem to be short.
    Now the laptop draws around 175 milliamps and does nothing. But the SSD gets a little hot. Nothing more.
    Thoughts?
    Thanx a lot.
