What ??? is this a desktop or laptop ?
Do you mean you cant see yout laptop screen ?
The display on your laptop is the interface through which you interact with and control your computer.
If it is not working, your laptop will become virtually impossible to use.
A laptop is a computer, and like all computers is subject to both hardware and software problems that may affect the display.
Before taking your laptop in for repair or getting rid of it, you should first check the display yourself to see if it needs to be replaced.
Check the laptop's battery and power cord.
If the laptop is out of power, the display will not work.
This usually happens if the power cord is unplugged and you were unknowingly running your laptop on battery power.
Check to make sure the power cord is plugged in and that the laptop has power.
Many laptops also turn off the display if it is being powered by its battery after a period of nonuse. Touching any key will usually turn the display back on if the battery is not drained.
Restart your computer. If a software program is stuck or malfunctioning, it may cause your display to stop functioning.
Press and hold the "Power" button on your laptop to reboot your computer.
If the problem was a malfunctioning program, the display will turn on after the computer restarts.
Check the brightness level of the display.
If the level is too low, the screen will appear dark.
The brightness controls are usually located on two function keys, such as "F9" and "F10." Look for sun or light icons on the keys.
Press the key with the larger icon to increase the brightness level.
Alternatively, on some laptops hold the "Fn" key while simultaneously pressing the "Up Arrow" key to increase the screen brightness.
Check the display closed switch.
Many laptops have a small button that senses when the LCD screen is closed and puts the laptop in sleep or hibernation mode.
WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL.

Only work inside the computer case when the power has been switched off and disconnected. Never open the power source.
Some of the below steps recommend removing physical parts within the computer.
While in the computer it is highly recommend that you be aware of ESD and its potential hazards.
Check your RAM.
The RAM is located in the middle of the motherboard.
There are tabs that you can push to release the RAM.
Remove it and put it back in place until the tabs pop out.
Loose RAM can cause your computer not to start properly where you want to see a video signal.
Remove the memory modules from their slots.
Take the opportunity to clean the slots on the motherboards and the memory module connectors.
Use compressed air to blow dust away and clean contacts with a soft cloth.
Do not use a metallic vacuum cleaner if it touches any component it may create a short and cause damage to the motherboard or other components.


Do not use solvent that may attract dust and never poke things like cotton buds in to slots. lightly rub an alcohol (Methylated Spirits) on a cloth not to hard let the alcohol do the work on the copper gold or silver tabs and r
Allow the pins to dry.
They will air dry in a matter of minutes.
If reseating the memory did not resolve the issue try swapping the location of the memory.
Make sure your graphics card is securely seated with no dust built up or in the socket
if you remove your graphics check the socket to make sure its dust free
If the switch gets clogged with dirt, it may get stuck in the closed position.
This will result in dark display even when the lid is open.
The switch is usually located near the hinges of the lid. Spray the switch with a can of compressed air to loosen the dirt so that it will resume its normal operation.
Plug an external monitor into your laptop.
If the problem is not software related, the external monitor will display the laptop's screen.
Connect the monitor by plugging the cable into the VGA, HDMI or DVI port on the laptop.
Press and hold the "Fn" key while simultaneously pressing the "F8" key.
The video output will be directed to the external monitor if there is a hardware problem.

Borrow a monitor and plug it into the VGA port. That might tell you whether the graphics card is bad.

My laptop screen isnt working but the cpu itself works. I hooked up an external monitor & it works fine! I tried the FN F5 toggle & still no results


It can be that the connection strip that runs through the hinges is broken and cut the supply to the diplay, so check this out.
It can also be a failure of the display drive, the motherboard or a power issue.
But for all the above you will need to open the laptop to check.

You should go to the display properties on your laptop while at home and disable the dual monitor setting. You should then have all programs open on your laptop screen and not on the secondary monitor. If running XP, right click an open spot on desktop and select Properties. If running Vista, right click an open spot on desktop and select Personalize. Go to Display Settings, select the second monitor and uncheck "Extend the desktop onto this monitor". Hope this helps.

That problem is from the processor fan not working in which will have affected your processor itself ok try and replaced the processor fan if its not working and if affected by the processor you will need to change that too for normal and adequate functioning of the system .ok
