Hi Paulus,

It sounds like a dying/dead LCD that needs to be replaced. Did these lines appear gradually over time?

I had the same problem and I thought it needed a new LCD screen but when I took the screen apart I pushed the connection in a little. It had just jiggled loose. Works fine now. I have the same laptop. Hope that helps
