MacBook Pro A1708 EMC 2978 powers on but no display
Hello I have a MacBook Pro A1708 EMC 2978 Late 2016 that powers on and I hear a little chime but there is no display.
It died in the middle of using it. Just poof, off, never came back on again. While I was using it nothing crazy like eating over it, spilled anything, happened.
I have tried many different key combinations that I have read on so many different forms that doesn't do the trick.
I have tried left buttons Shift, Control, Option, Power button, quick press. I hear a little chime when I do this. When I press the caps button, the green light turns on when I press it and off when I press it. But no display.
I have held down left buttons Shift, Control, Option, and Power button for 10 secs with and without the USB-C power connector. Again, I hear a little chime, no display.
I have unplugged power, disconnected the battery, held power for 10 secs, plugged in power. I hear a chime but nothing. I have done that….then….plugged in battery, hit power button, hear chime, nothing.
I have tried fn, control, command, power. Yes, I hear a chime when I try to turn it on but no display. Also tried left shift, fn, control, option, command, power. Again yes chime, no display. All this with and without power connected.
I have not tried an external display yet as I do not have that connector.
Am I just screwed and need a new logic board?
Is this a good question?
