If the problem is only on the internal screen, then it's either a failing screen or failing video cable.

Need new lvds cable?

Can do this if broken inverter?

 

[Intell]

Yes, possibly a new LVDS cable. A bad inverter won't do that. A bad inverter would cause part of the screen or the whole screen to not light up, but still show a good image.

Thanks for posting this with images!
Those images helped me diagnose my issue.. usually folks talk about vertical stripes and darker at bottom when compared to top and I have searched high and low and finally had someone who was having the same issue as me and pictures to back it up.

Much appreciated and now to get a replacement LCD ...
