Screen is black/blank..computer powers up and fan is working...No screen though??? PLEASE HELP!!
SOURCE: toshiba blank screen
i had the same problem and i replaced the inverter but that did not work then i replaced the backlight and no problems since then.
This seems to be a problem with alot of toshibas and i dont know why they install these useless backlights. Backlights are supposed to outlive the laptop.
I paid about 20 dollars for the backlight rather than pay $200 dollars for the whole LCD but it is a very tricky job so be very carefull.

Try to shutdown, remove battery, remove AC plug, Press and Hold Power button for 30 seconds, replace battery and AC adapter and test.
do you hear windows booting ( the startup sound) after a few minutes, if so there may be a monitor hardware problem

Take out the battery and only hook up the ac adapter.
If that doesn't work then, try reseating your memory one stick at a time in each slot one stick at a time and make sure you turn the laptop on after each stick reinsertion.
If you don't get video after that then go ahead and take the dvd drive out and also the hard drive.
If you dont' get video after all of this then that means that motherboard is bad and would need to be replaced.

Take out the memory and reseat each memory stick one stick at a time in each slot one at a time. Be sure to turn on the laptop after each stick reinsertion. If you don't get any video then go ahead and take out the battery completely and only have the AC Adapter hooked up and turn on the laptop, this will make sure that its not an overdrained battery causing the laptop to show no video.
If this doesn't work then go ahead and take out the hard drive and dvd drive, then try turning on the laptop. If you still don't get any video then the last thing to try is to change the output from monitor to LCD, you would do this by pressing the FN key + the function key that has a pic of a monitor or it will say crt/lcd.
If after this last step you can't get video then the motherboard is bad and would have to be replaced.
There are several reasons that your Toshiba laptop screen may not come on, even if the laptop appears to be running, and several options you may try to get your screen back up and running without an expensive service call.
Common causes for a blank screen include a backlight that is turned off, a display toggled to an external monitor and improper shutdown errors.
To avoid blank screen errors after your current error is fixed, make sure to follow all instructions in your user's guide to care for your Toshiba computer.
Shine a flashlight directly at your screen and look for an image.
If you see one, this means the backlight on your laptop is off but the screen is still working. This backlight normally turns off only when your screen is closed.
Look for a small metal or plastic pin near one of the screen hinges.
The screen pushes this pin in when it is closed, so if the pin is stuck in the screen closed position, the backlight will remain off.
Tap the pin several times to release it.
You may need to use a small object, such as a pencil tip or straightened paper clip, to reach it on some models.
Monitor Toggle
Press and hold down the "Fn" key if you do not see an image when you use the flashlight.
Tap the "F5" key several times while the "Fn" key is pressed.
This will cycle your screen through the various options that toggle the display to an external monitor.
Attach an external monitor, restart the computer and try this method again if no image appears on the laptop screen.
Click "Start," "Control panel," "Hardware and sound," then "Device manager" using the external monitor if you get an image there but cannot toggle the image back to your LCD.
Select the "Monitor" option to expand your selection and select your LCD monitor from the device list.
Click the "Driver" tab and select "Update" to update the driver, as this error is likely caused by a software driver error.
Force Restart
Press and hold the power button until the computer shuts down completely.
Check the indicator lights at the edge of your laptop to see if the computer is truly off or if it has simply gone into hibernation mode.
If it is off, all lights will be off except the battery-related lights if you have a charger plugged in. In hibernation mode, the power light will blink slowly.
Press the power button to restart the computer again after leaving it off for 15 to 20 seconds. This may fix the problem.
If the blank screen returns or you get a flash of images and then a blank screen, move on to the next step.
Force Power Down
Unplug your laptop from the power source.
Remove the battery by pressing outward on the battery latch and pulling the battery unit completely out of the computer.
Press the power button several times to completely discharge the computer.
Replace the battery and plug the computer back in after about 30 seconds.
Press the power button to turn on the computer.
If you get an error screen upon startup, choose to restart Windows normally.
This error is caused by improper shutdown procedures.
Hope this helps
