Laptop Screen Problem

[Bijutoha]

Hi there! I'm using HP presario c700 . During few days I'm going to see display is not working properly. I mean I can't see anything without sound, It's display is going to show a black shadow with some scratchs.

Please anyone say something, what should I do?

Hi there, have you tried hooking up to an external monitor? This will help you determine if it's a problem with the screen or logic board.
