    MacBook Pro A1707 Won’t Boot – No Display, Fans Spin Briefly

    Hi everyone,
    I’m currently having an issue with my MacBook Pro (A1707). It doesn’t power on or make any sounds.
    • The charger is a generic third-party unit that had a loose connection at the AC input (127VAC). I fixed it, and now it delivers 20VDC to the laptop.
    • When connected, the fans spin for about 30 seconds before shutting off.
    • No display, no audio, and no signs of life during this time.

    Any ideas? Could this be a logic board issue, or is the charger still a problem? Thanks in advance!

    MacBook Pro Mid 2012 turns on, fans spin for five seconds and turns off, repeats
    by Gigabit2
    I have a MacBook Pro Mid 2012 with 820-3330-B board.

    The laptop shows a green light on the charger, turns on and the fans spin for about five seconds. Then it turns off and this repeats over and over.

    Before it turns off, the SuperDrive (DVD/CD drive) makes a noise like it does when it first turns on from cold (on a working machine).

    I am stumped, can anyone help?

    Macbook a1707 2017 model 820-00928 GPU issue
    by sofles
    Hello there

    I have problem with Macbook Pro 15" 2017, model 2017, MB code 820-00928.

    I bought it as broken with some artefacts on the screen, first I thought that this is problem with ribbon cable but after inspectiing ribbon cable I know it is fine. I tried to reinstall macOs and then I figured out that this must be something with GPU as installation freezes at the end (when drivers are loaded). I installed Windows and was able to install every each of drivers except GPU driver, as soon as I tried to install GPU driver - black screen and restart.
