Does the computer work properly when you connect it to an external display? If you press lightly all around the edges and the surface of the LCD panel, or maybe if you lightly twist is and flex it a little, if the problem changes or goes away, likely there are problems with the permanenttly attached ribbon cables that run the LCD panel. If that is the case you might need a new screen.
