Go to Toshiba's website and download the latest graphics drivers for your graphics card/laptop, depending on how they list it.

kiumars, i'd like to propose you to reflash the bios chip. sometimes the chip is being broken(especially the PMC BIOS chips).

the lcd screen may require replacement. You can get kits if you're a tech. Also plug the laptop into an external monitor to check the video chips. IF you get video externally, your LCD is jacked. Another possibility is the screen switch is broken. This is is the switch that turns off the screen when you close the lid. This happened on mine. You will need to replace this or repair it if this is the case. Mine was superglued back.
