Bad Laptop Screen SYptoms (negative colors)

Whats wrong with my laptop screen? My Toshiba A 305 Laptop screen colors look like "negative" colors. This happened after I connected an external monitor. The external monitor works fine but not the laptop screen. I tried system restore, updated video driver and reinstalled video driver (from Toshiba).
