Black screen but I can see the menu bar?

Hi guys,

I've got a Mac book Pro (2014/15 I think, Model A1502). Last night I left it on and then in the morning after plugging it in to power, I turned it on to see only a black screen with glitchy lines running through it. The strange thing is that I can see the menu bar at the top of the screen, which would suggest to me that my hard-drive is fine but that there is something physically wrong with my screen. Has anyone else had a similar problem, and if so is it something that can be fixed?! See picture attached.
