    How's the cleanliness status of your laptop? I have serviced many systems which are boggled down with dust and won't boot up consistently because of the overheating of the CPU. No airflow, no cooling. Check and report back Good luck

    God Bless

    Is it the hard drive making the motor sound or is it the fan?

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

@rashid386

If you turn the computer ON and you can hear that something's running on the background but there's no display , this is a sign that the screen's FL Inverter (this is the chip that controls the backlight of your LCD) or the LCD screen itself is already wearing out and needs to be replaced. If you can see a background image but there's no backlight - you need to have the FL Inverter replaced. If the screen is all black, you may need to have the LCD screen replaced. If you know your way around the computer, you could order screen replacement here and disassembly guide here.


Good luck.

Dell inspiron 6400 start up problem.


Can you hear the hard drive spinning and the computer appears to be running but you you get a blank screen. If you look at the LCD screen at an acute angle and you see a dim image. then you have a backlight problem. To determine if you have a video card problem or a lcd screen problem, Connect an external monitor to your laptop and power the monitor up first and then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.
Get back to me with the results of these tests and any error messages etc. so I can advise you.

Blank screen upon startup


Try taking out the hard disk, plug in power and see if you have a display on your screen or external monitor. if same thing happen, try taking out the memory card. If you hear a beep sound it's a faulty mem. card, if no beep sound appears I suspected it's a motherboard faulty.

Monitor is blank when we turn the computer on.


Maybe not. Find the FN key. It is usually BLUE in color
Then look on TOP row of Computer keyb (or all over) and find CRT/LCD.
Press the FN and that key and your screen should come back. You accidentally sw. it to CRT (outside, external monitor)
