I have this really weird problem.

Screen is 90% black (from bottom to top, only top bar is visible). I changed it with another from a donor but there was some dimmed and almost black lines on top. I tested his original display on another Macbook and it works perfectly fine, so I thought maybe it was a LCD cable issue. I assembled it back but screen doesn't turn on at all. I tried with the replacement one (with the dimmed spots) and it doesn't turn either.

Currently it doesn't light up with both of the displays. It has picture on external monitor, so I know it's booting.

Any idea what to look for?
