Horizontal lines across laptop screen

[Modena]

Hi there, I turned my laptop on and all I got was these horizontal lines white/gray ones throughout the screen. I can hear everything loading correctly in the background, and I can even get the screen to display a nice correct image if I bend it at the top in and out a little bit.
So what do you guys think it could be? I was thinking maybe a bad inverter, or ribbon cable? I'm not sure and would appreciate any info so that I can order a whole new screen, or a specific part, thank you.

Also if it helps I plugged it into a monitor through VGA and it worked fine. I also reseated the cable from the board to the screen and that did nothing.

I think you are most probably right about ribbon cable, I am unsure how much it will cost you, but it seems to be the logical point to start with, especially considering that you said "it works fine if its bent a little bit".
