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