Sorry It took me this long to reply
Anyways you can't really get the cable that attaches the motherboard to the screen. You Would have to get a new screen.
When you took it out did you clean the connectors??
One of the reasons that this can happen is if you put something heavy on top of the laptop and damaged some of the components.
Either case I think the quick fix is to buy a new L.C.D. Don't buy it of the manufacturer they are to expensive. I always buy my stuff of third parties.
Just look for a reputable seller online that has your screen with a good return policy just in case..
