Question about HP 435768-001 - Compaq Presario C300 Series 15.4 WXGA LCD Display
Confirm the issue lies with the screen and not the graphics chip by testing the laptop connected to an external monitor, if you get a good diaplay on an external monitor, then the screen backlight and maybe the inverter is damaged, it could also be a faulty VGA cable. The only way to test this is by replacing the screen.
If however it fails to display correctly on an external monitor, you have a failing graphics chip
