My toshiba l355d black screen all fans and lights are working


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

Benq fp581 screen goes blank after about half a second evertime i turn on my computer.


Even thought the monitor looks blank check to see if you can see a faint image (shining a flashlight at the monitor sometimes helps). If you can see an image it could mean that the inverter board has gone bad.

I have also heard of an overheated computer causing a similar problem.

Have HP slimline series. Came back from a break.


Try another monitor on it to verify it is the video card that has gone bad. If it does not work with another monitor then that is the likely culprit.

Asus Monitor boes blank and comes back after power recycle


1. You can see images on the screen for a few minutes. That means there is nothing wrong with your computer.

2. When your screen goes blank, if you disconnect and then reconnect the monitor, it shows fine again for a few minutes before going blank (or dim) again. That means the problem is not with you video card.

3. It always shows the image after reconnection for exactly a few minutes before going blank again. yes? this means that there is nothing wrong with your cable.

Conclusion: Sorry, but you do not have many options. I bleieve that the problem is with your monitor that's going bad. Its far cheaper to get it replaced than to repair it.

No output from graphic card


The video output on many portable computers toggles off and on with one of the function keys. Look for a function key with the image of a monitor on it, then hold down the Alt key and push the function key once or twice. It usually has several choices that you rotate through - computer monitor only, video out only (your screen goes blank) and both screen and video out.

Monitor displays breifly then goes to blank screen


Hi this is the way how to examine what's wrong with your LCD monitors. Power on both CPU and monitor. After going blank, you check that you can see the image on the screen by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem. Like me, I can see window image using flashlight and check lamps inside. Some of them were broken and it is easily replaced. If you cannot see anything on the screen, there'll be some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or burn spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so.

Blank


Unplug the monitor from the computer,
it should display the diagnostic screen on monitor in color.
if not reconnect it and boot computer or attach to a running computer with some stuff on the screen,
get a bright light and shine on the screen at an angle do you see the stuff/desktop.if you do the lamp or power supply is bad.
if the monitor is lit and the lamps work but no diagnostics then the video cpu on the monitor is bad.
