    A1706 Macbook - Machine turns on but LCD and touchbar are blank

    EDIT: I see now that this is a "flexgate" issue. One of the backlight cables is almost torn. Is the touch bar problem related to the screen?

    Hi, sorry I can't find board number (where is it printed?)

    This machine will turn on (CPU gets warm, caps lock lights up, touchpad clicks, you can hear charging "chime" when plugged in) but the screen and touchbar remain black. No image and no backlight. The fans also don't turn on, but maybe because CPU isn't hot enough...

    It appears it has been dropped on the corners before.

    Although it looks like some liquid may have entered the keyboard, I removed the logic board and it is spotless.

    I tried USB-C to HDMI and still have no image. I am not sure if the image should automatically show though....

    Unfortunately I have no other LCD to try. I do however have an extra lid/backlight and when I connect it the backlight does light up. Still no touch bar and can't confirm display on LCD.

    Any tips?

          Macbook A1706 EMC3071 (2017 Touchbar)
          by kurtspirit
          Hello,

          I have a Macbook Pro 2017 Touchbar (A1706) that suddenly shut down for no reason.
          So I took it apart and started measuring.
          The PP3V3_G3H seems problematic. I traced the line to component U6903 and on Pin 10, I measured 1.9V instead of 3.3V.
          Unfortunately, my skills stop there and I don't understand where this type of failure can come from.
          I saw on videos of repairers that the failure could come from the U7000 component which would be at the origin of the 3.3V but they have absolutely no voltage. I have a 1.9v...
          What do you think ?...

          A1706 - Macbook pro - one USB-C port only 20V 0A
          by obelix24
          I just got in my hands one Macbook pro A1706. It was originally not turning on (only 5V 0,2a on all ports (and 3 ports were restarting ampmeter when connected)

          I've replaced one CD3215C00 IC and now macbook is fully working (20V and charging fine)

          There is only 1 issue that one USB-C port is taking 20V but 0A (after replacing CD3215 it was fully working and i was charging macbook on this port) but then it just turns off (ampmeter) and started with only 20V 0A.

          There were some broken pads under CD3215 but i've recreated them.

          What should be...

          Macbook Pro A1706 820-00923 no power after replacing top cover and keyboard
          by johnbeton
          Hello,

          I have a A1706 with 820-00923-A board. The laptop came in with non-working keyboard. I bought a new top-cover with keyboard and transfered everything to the new topcover.
          Since then the macbook will not charge or power-up. Before replacing top cover, I started the macbook to test, and it worked fine apart from keyboard. Then shut it down and did replacement.
          This is what I measure so far:


          Resistance from F7000 to ground is 123 Ohm on pin 1 and 2

          PPBUS_G3H = 0,79v
          PPBUS_HS_CPU = 0,79v
          PPBUS_HS_OTH5V = 0,79v
          PPBUS_HS_OTH3V3...
