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.

Thanks a lot I will try to check the cable on the mother board, is it replaceable ?

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.

Try to connect an external monitor and if you can see lines on it also, the ribbon cable is the problem.
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.
