Check for brightness adjustment of the LCD panel. You might have accidentally adjusted it to lowest brightness.

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.
http://www.kitchentablecomputers.com/static.php - rules
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.

How do i switch to external monitor


Virtually all IBM and Lenovo ThinkPad and ThinkCenter laptops allow you to hook up an additional monitor or projector to the computer. When you add an external monitor or projector to your notebook, you can choose to view the display on the computer, on the external device, or on both the laptop and the external monitor or projector at the same time. Toggling between viewing devices is as simple as pressing a couple of keys on the keyboard.

Shut down the laptop. Plug the VGA monitor cable from the external monitor or projector into the blue VGA port on the back of the computer. Turn on the external monitor or projector first, and then the Lenovo laptop. Allow the notebook to boot into Windows normally. Press the "Fn" and "F7" keys at the same time to switch the display from the laptop to the external monitor or projector. Press the "Fn" and "F7" keys again to enable the display on both the laptop and the external display device. Press the "Fn" and "F7" keys again to display screen contents only on the laptop LCD. choose support you need http://www-307.ibm.com/pc/support/site.wss/MIGR-54305.html http://www-307.ibm.com/pc/support/site.wss/MIGR-4YQHUC.html enable tv out on thinkpad http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-58625

Lenovo 3000 n200 0769AMU press power on switch green light on after about 1 sec screen still black no HD light fan running


Welcome to Fixya

Try to drain the electrostatic charge of the motherboard that usually cause this issue. I wrote a tip on how to do the power drain. Try to plug in external monitor on the VGA port and see if you are getting display using external monitor. If you are getting display using external monitor then the problem would be the laptop LCD. If you are getting the same black screen using external monitor then the problem is already the motherboard.

Thank you for using Fixya!

THE SCREEN IS BROKEN ON LAPTOP CAN I CONNECT IT TO MAIN COMPUTER SO I CAN USE SCREEN ON THAT


You may need to press a key combo to switch displays. Many times this is Fn + F7 or Fn + (some F key)
You may have other problems with the system that prevent the display from working.

Screen will not function. No video at all.


here's what you can do.
it might be blank due to the togle feature so try this

***'Monitor Toggle Features (Converting the Screen Using the Shortcut Key) If you have an external monitor connected to the computer, press Fn + F7 keys to rotate the display mode between LCD only, Monitor only, and LCD + Monitor both in order.'***
as long as you hold Fn and press F7 these mode's will change in order respectively.
if the issue was due to the inappropriate display mode it can be fixed by toggling.


since your display is totally blank... you need to find out weather it is the screen or the video card in the notebook. either ways if hardware is faulty your guarantee should cover it.

In case, you are looking for Manual in English you can find it by googling up your Notebook model number.

If the issue were with the display adpters or drivers then you can fix them by connecting and toggling to external monitor.

Without my laptop (samsung q35) being linked to the mains it is nearly impossible to be able to see what is on the screen, i have tried to adjust settings but this has had little or know affect. pleas help...


You may check power settings in control panel and see if somehow the settings for your screen are set to turn off or the power settings program has been corrupted for some reasons. Although I doubt that this the case it is worth to check.

At the same time there is a need for more information about how did that start or if you have done any physical changes to the computer.

Another thing you may do is connect it to an external monitor and see if the same thing happens to the external monitor. If that is the case then I think there is something wrong with your display card.
