Laptop Screen Turns White

[Pan45]

My HP Pavilion G4 laptop screen is white when I turn it on. When connected to an external monitor, it works fine. Any suggestions for the cause and a solution?

If the external monitor is fine, then you know the problem is from the mother board cable connection to the screen itself.  The problem point for notebooks is where the cable goes through the hinge.  You could try to wiggle that to see if the picture changes. The other possibility is that the connection from the cable to the screen has come loose and the final solution I can think of is that the screen itself is bad.
