The screen goes black or dim when I touch the lid or move the laptop

When I touch the lid or move the laptop a certain way, the screen goes black or the contrast is really dim. The buttons on the laptop are still lit but everything else seems shut off.. but not really. I try everything I can to turn it on but it wont turn on. So I have to force it to shut down. I don’t know why it would do that.
I think there could be a problem with the screen cable. This cable connects the laptop LCD screen to the motherboard and apparently the cable is bad and has to be replaced. That would be my guess.
Here’s what you can do in order to narrow down the problem. Test your laptop with an external monitor attached to the VGA port. Set your laptop to output video to both, the internal screen and external monitor. Now touch the lid or move the laptop. If the laptop screen goes black or dim, but you still can use the laptop with the external monitor, most likely it’s related to the screen cable. Apparently it has damaged wires inside the harness and there is a short inside the harness when you move the lid. If that’s the case, the screen cable has to be replaced.
