    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

          Hello,

          I am looking for the boardview file and the matching schematics (PDF) for the following MacBook Pro:
          • Model: A1707
          • 15-inch, Mid 2017
          • 3.1 GHz Core i7
          • 16 GB RAM
          • Radeon Pro 560
          • 1 TB SSD
          • Board number: 820-00928-A
          I already searched the forum, but so far I haven’t found a matching boardview for this board. In several posts I came across, it was also mentioned that the uploaded files were often incorrect.

          Thanks in advance!

          Greetings from Germany...

          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
