How can I use the screen of a broken MacBook? I have a 17” unibody MacBook Pro that is broken (the GPU and motherboard are gone). Is it possible to use its screen as an external display?
I suppose it would need some kind of specific connection to feed power to the screen as well as the video.
Imagine building yourself a monitor, and the only part you have is the screen display itself. No input port, controller circuitry, nor power supply.
There are not going to be easy steps that you can follow unless you can determine the OEM of the panel and dig up a kit and guide to provide a display assembly that drives that LCD panel.

Use MacBook Pro LCD Screen as a standalone monitor
Can my Macbook Pro&#39;s display receive inputs from other sources?
