After reassembling my macbook pro, the screen goes black. I can hear the sound when turns on but nothing is shown on the screen. How do I know if i broke the cable when I took it out from the connector because it was working fine before openning my mac?

just open it again, check the cable that is connected to your monitor if its connected if not connect if so you probably broke it :/

Piece of cake, took an hour or so, but I was being extra careful. The only sticky part were the backlight cable and the keyboard ribbon cable ZIF socket, those two items I found fiddly to get re-inserted properly. Thanks for the tutorial.
