Question about Computers & Internet
The display in a laptop connects to the motherboard by a flexible cable that passes next to one of the hinges. Because of the flexing when you open and close the lid, wires in the cable can break and cause the trouble you're seeing.
The cure is to replace the cable. It's not difficult to do, but it's not always easy to get a replacement. In some brands and models, the cable isn't available except as part of the complete display. This may be quite expensive. If a replacement cable is available, you need to be sure it's the right one for the display panel used in the computer. The same model computer may use different parts depending on when and where it was made. Using the wrong display cable won't damage anything, but the display won't work correctly.
You don't give the make and model of your laptop so I can't tell you any more. But you can search online for "replacement display cable" for your specific computer and see what's available. There are many websites offering parts and how-to information, so you may find what you need.
Good luck with the repair, and thanks for using Fixya!
