    Macbook A2141 820-01700 No Image screen and extern

    Hello friends
    here reporting after time.
    I have this board 820-01700, it turns on and consumes almost 4 amps but it does not display an image on the screen and also an external monitor
    shift key is activated and the touch bar lights up.
    test with a usb mouse the mouse light comes on.

    is it video?

    Thanks

      Does your touch bar display the graphics or only lights up ?

      This model is impacted by FLEXGATE (for the LCD panel) but that does not affect your external display not working.

      If the key caps LED is toggling, the OS is booted.

          The logo appears for 3 seconds, then a black screen appears, but the machine is still on.

              Check if the graphics are still present on the display with a flashlight / phone in torch mode - shine on the front of the display to view it.

              If yes but is dark, then the fault is with the backlight circuit.

                      Hi there. You mentioned that this model had flexgate issue too. I'm planning to buy one wich is perfectly working on external display and only backlight is not working (you can clearly see image on internal display panel using a torch). That could be both backlight circuit or backlight display flex at this point?. I have not a working display to test in case I decide to proceed and buy.

                          Hello! A little liquid got onto the 8500 connector, which led to a short circuit in the EDP_INT_AUX_N line in the U9850 . according to the scheme U9850 is identical to the MacBook A1707 820-00928 and I took it from this board and replaced it! (maybe they are not interchangeable? Tell me, otherwise the markings on them are different but according to the scheme they are identical)! I checked the display works on A1707. The cable was replaced and installed from A1707. (as I understand, on A2141 you can install a cable from A1707-A1990, but not vice versa). MacBook works with external display!...

                          Hi there.

                          I have Macbook Pro 16" 2019, model number A2141, motherboard number 820-01700. I have some problem with dedicated graphic card. When Macbook switches to dedicated GPU it is getting instantly hot and starts to show glitches on screen, then it freezes (trackpad is not clicking anymore) and shuts down.
                          I tried to reinstall MacOS But it was a pain, it started to show glitches in middle of installation and I could not finish it. I only was able to reinstall MacOS when I put Macbook outside (it is winter and -2 Celcius).

                          Now situation looks like this, If...

                          MacBook Pro A2289 (820-01987-A) No boot/image, but boots to DFU
                          by baglaivlad
                          Hi everyone. Just a reminder I am not a professional repair technician, fixing Apple electronics is my hobby.

                          Recently got my hands on MacBook Pro A2289 with interesting behavior. Pristine condition, no water damage, no visual issues whatsoever. It has no image, no CapsLock, no life except the fan is spinning. But it is able to boot into DFU and recognized by another MacBook. I tried to revive and restore the laptop, but the process ends when the MacBook usually should show an Apple logo with a progress bar. I assume the main power lines and T2 are working. It seems like the Intel...
