Inspiron 5520 Screen Transparent Blue

Hi,

My Inspiron 5520 screen has started to turn a bright blue depending on the angle of the screen. The blue is see through - you can still see and use the computer normally, just with a blue overlay in different sections. I can sometimes get the blue to go away by adjusting the angle of the screen. I'm guessing it's some kind of short or cable issue between the base of the computer and the screen? Anyone have any ideas? I've tried researching but only find "blue screen of death" which seems to be more like a solid blue screen.

Thanks!
