    The most likely cause is a loose or damaged cable that connects the screen in the lid to the motherboard. There is also a possibility that the internal connections inside the screen itself are damaged.

    It depends on the design of the display panel for that particular laptop. It may have a socket and use a separate cable to connect to the motherboard or it may have a flex cable built into the display.

    Did you mean that the other way around? If the lines also appear on the external monitor, it usually indicates a problem with the video controller IC or with Video RAM. The ribbon cable would only affect the video going to the built-in LCD.
