    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...

          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....
