It appears that you most likely have a bad video inverter. This is a fairly common problem with Toshiba Laptops. The cost of an inverter ranges from $40-$60

I am not sure what brand of laptop you have. In any case. Do the following 1. Turn the laptop off 2. Turn the laptop back on while tapping on the F8 key. 3. Choose the option to go to safe mode 4. In safe mode right click on my computer, then left click on properties, then click on hardware tab(Windows XP) 5. Click device manager button 6. Scroll to your video adapter and uninstall the drivers 7. Do the same for items on monitors 8. Reboot the computer and let the computer detect the devices again. 9. You may need the drivers cd that shipped with the laptop ( and sometimes the laptop loads the drivers from a default location on the hdd.) This should resolve the problem.
