    MacBook A1708 no display after flexgate repair

    Hi everybody !
    I have a 2016 MacBook Pro with previous flexgate issue.
    Before I started working on it, video signal was present on external monitor with USB-C and, luckily, is still present.
    What is missing is the video on the internal display, MacOs doesn't seem to recognize it in system settings/monitors.
    I have cut off the flat connector of the backlight and soldered all the jumpers directly on the LCD board, as shown in this site: https://logi.wiki/index.php/A1706/A1...nout_(FlexGate)

    Nonetheless, even with a flashlight I can't see any picture. I've tried some measurements on the board but none of the CPU lcd/bklt enable signals go high, including the EDP_BKLT_EN that doesn't pull the SD pin of the U8400 to ground, so the voltage divider of the Q8400 is not actived, and the MOSFET doesn't go in conduction.
    I've even tried multiple SMC resets but never worked...
    What can I do?
    Thanks
Working...
