    macbook pro A1707 board 820-00281-A

    Hello

    I'm trying to repair as best I can my macbook pro which suddenly turned off even though there was nothing plugged in and I wasn't touching it. I noted several voltages or not, I'll indicate them to you below if you have any ideas I am very interested thank you in advance

    PP3V3_SUS ok 3.3V
    PP3V3_S5 ok 3.3V
    PP3V0_G3H ok 3V
    PP5V_PMICLDO ok 5V
    PP3V3_S5 ok 3.3V

    PP1V0_SUS no 0V 57hom
    PP1V8_SUS no 0V
    PP3V3_S0 no 0V
    PP5V_S4 no 0V

    The consumption of the Mac is 0.014A and 20V so the USB chips work

    looking at the diagram I think that I can simply bridge the two pins 1 and 2 because I do not have the second component to solder on my original motherboard after that I do not know the functionality of this component

      by leonemax81
      Hi guys I have a Macbook a1707 with motherboard 820-00281, without liquid damage that behaves strangely, with the battery connected the Macbook does not turn on and the USBC meter stops at 5v in loop, when I disconnect the battery the Macbook turns on and works fine, I have already tried to replace the battery twice without success, as soon as I connect the black cable of the battery the Macbook does not turn on, it stops at 5v and in loop.

      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...

      MacBook Pro A1707 Won’t Boot – No Display, Fans Spin Briefly
      by Herby94
      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!...
