    Macbook A1707 - 820-00281 - No Power

    Hi Everyone,

    I have one MacBook Pro A1707 - 820-00281 No power. USB-C meter is showing 19V - 0.05A.
    There is nothing short to ground. Voltages are as below.

    PPBUS_G3H - 12.62V
    PP3V3_SUS - 3.3V
    PP3V3_S5 - 3.3V
    PP3V0_G3H - 0V
    PP5V_PMICLDO - 5V
    PP3V3_S5 - 3.3V

    PP1V8_SUS - 0V (0.6M)
    PP3V3_S0 - 0V
    PP5V_S4 - 0V (6k)

    EN missing for PP5V_S4.

    Is it looking like PCH not turning on?

    Someone can help me?​

      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.

      Apple MacBook A1707 No Audio/Sound
      by tommy97
      Hi,

      I'm having an issue with an A1707 MacBook Pro—there's no audio output. Initially, the MacBook came in with a no-power problem, and I found a faulty U6400, which I've now replaced. The laptop now powers on, but there's still no sound.

      I've also replaced U6300, but the problem persists.

      Here are the current voltage readings:
      • PPV18_S0: 1.8V
      • R6402: 1V
      • R6405: 1V
      • R6403: 1V
      • AUD_SPKRAMP_RESET_L: 1.3V
      • PPBUS: 12.6V

      MacBook Pro A1707 Motherboard Diagnostic Help – CD3215 heating and Fluctuating Rails
      by Cemal Odabasioglu
      Hello everyone,

      I'm currently diagnosing a MacBook Pro A1707 motherboard that does not power on. I've gathered some data but am stuck and need expert advice.
      Note that i'm a beginner in electronics and i'm trying to learn while trying to repair this macbook that my work gave me. I'm really curious and love understanding how thing works and i already learned so much.

      Only one usb c port is taking 20v and have 12.5v on PPBUS_G3H. when trying other ports, 2 are not going to 20v and one is going to 20v but the CD3215 is getting really hot.

      Observations...

      Hello,
      Namaste!

      We have a Macbook A1707 which came in for repair. Someone had already tried to work on it and there were traces oh heat and burns on the board.
      The charger was Stuck at 5v and the there was some caps shorted around U3100.
      Turns out there was corrosion under U3100. Same was Reflowed and the Macbook turned on. Works fine but having 1 issue whenever the Macbook is idle and goes into sleep mode. It will WAKE for 1 Second and then do a restart.

      It will Display a Black Screen with error message saying Macbook Restarted because of a problem....
