Dell Laptop Screen Horizontal lines at boot or wake up

Recently my Dell XPS laptop on boot up or waking from hibernation has a few horizontal lines scrolling upwards; sometimes it has a gray screen with lots of horizontal lines on it. If I move the laptop lid back and forth the screen is fine.

I have run Dell diagnostics and all is reported as OK. I have taken the back off and all seems OK. I assume there is a connector between screen and computer but I cannot locate that. I assume that if a display setting has changed, the screen would be constantly poor?

Any ideas?

Hi Fruit Bat - I think you are correct. Just booted up and same problem, then lightly knocked the top of the lid downwards and the proper screen appeared, so a loose connection possibly. I did ask for a quote from your link but fear courier charges will kill this!
