Screen replacement turned out black

[hejamartin]

Hi everyone,

I had an unfortunate accident which made my Macbook Pro 2017 A1707 model - to have a broken screen.
I replaced the screen with another screen from a A1707 macbook pro.

It was semi-easy to replace - just the three antenna cables that was a little bit tough to snap back.

The screen is just black now after booting up. And I do not know why it is that. I cant figure out the problem.
I have reset Pram/nvram, and everything, safe mode etc.

But internal screen goes undetected - I have an external monitor. Anyone that has some valuable input to give me?

Does it show any life at all? If not maybe a faulty screen.

Try reseating the connectors. Some possibilities.
- Connectors improperly or not fully inserted.
- Damaged connectors
- Faulty replacement screen
