Black screen when turned onno display


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

Try to Initialize the Spool Disk: NOTE: Initializing the spool disk will delete all jobs in all queues. This procedure can be used when a corrupt job has caused the printer to stop printing. This procedure can also be used to correct certain machine faults.
  1. Press the ON / OFF switch. The power switch is located on the front right side of the machine under the Control Panel.

  2. Wait until the Touch Screen goes blank (this may take several minutes).

    CAUTION: Make sure to press the correct buttons all at the same time. An incorrect button combination may delete all customized printer settings.

  3. Press and hold down the [6] button on the numeric keypad, the [Energy Saver] and the [Stop] buttons simultaneously while powering ON the machine. Continue to hold down the three buttons until the Touch Screen displays several lines, goes blank and then displays lines again.
  4. Release the buttons. The machine will continue its normal boot up procedure to initialize the spool disk.

My grandsons PS3 turns on but it just shows a blank screen, we are using av cables. I found how to get into the diagnostic mode and this part works but it did not fix anything. The light turns green but...


The ps3 automatically detects an HDMI cable not av cables. You are going to have to reset the video settings back to factory. This can be done by turning the unit completely off(Hold the power button until you see a red light. Then turn the power switch off in the back. If you do not turn it off in this order, and just turn the switch off in the back it can corrupt your hard drive!). Once the unit is all the way off, hold you finger down on the power button in the front. While continuing to hold the power button in the front, turn the switch on in the back. After several seconds, you should hear a couple beeps. This confirms the video settings have been reset. Don't get discouraged if it does not work on the first try. It sometimes takes several attempts. If you have any further questions feel free to contact www.wiredextreme.com.

Monitor revives only after cycling the power many times


Unscrew 4 screws on the back side. Place the monitor with the front up and open it along the upper seam. Turn it again and lift the back cover. Shift the inner case "up" and take the button holding plate out - it is being held only by a tape. Inspect it and clean it. You might have to replace the condensers and/or switches on it.

This might solve the problem, but there may be other causes as well.

Good luck!
