          MacBook Pro M1 A2338 820-02020 - No WiFI/Bluetooth or internal display
          by mcbadcbv
          Hello,

          I have a MacBook Pro M1 A2338 820-02020. It boots to OS but WiFi/Bluetooth are non-functional (exclamation point through WiFi symbol in menu bar) and the display is not working.

          Starting at the WiFi chip... PP3V3_S2_WLBT_ISNS is fluctuating at around 2.4V. No shorts detected around UL000.
          PPBUS_AON is 12V steady, but PPBUS_AON_3V3_S2_VIN_ISNS (measured at CC721) is 2.76V.
          LC710 is getting 2.4V at P3V3_SW, which explains PP3V3_S2 fluctuating around 2.4V.
          No detected shorts around UC710.

          This makes me believe that RD560 has failed and...

          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
