MacBook Pro powers on, but display is black.

This happened out of the blue. Screen went black and I haven’t been able to get it to come back on.

Prerequisites:

  • No liquid damage
  • No drops/impacts recently
  • Nothing out of the normal leading up to the issue
  • Capslock key lights up
  • Charging sound when cable is plugged in
  • Trackpad clicks
  • No keyboard backlight
  • No startup chime

What I’ve tried:

  • SMC Reset
  • PRAM Reset
  • Removed bottom cover and reseated battery connectors and other connectors that were easily removed. Nothing looked out of the norm.
  • Booted laptop without battery connected using AC adapter

What I haven’t tried:

  • Plugging into my own external display .

Apple’s brief diagnosis:

  • Nothing shows on external display
  • Likely logic board
  • $500 to replace logic board

*


Any suggestions would be greatly appreciated. A $500 repair is not in the budget right now. Thanks!

You'll need to validate what Apple tested. If the external monitor fails to work then you do have a logic board failure.
