Lcd screen not working

Step 1:
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. 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.

My fn key and home for making screen light bright isnt working can any one tell me is there any other way to make my screen light high???please help its so dark

You should try to determine why your Fn keys are not working... just to make certain, the Fn+Home key will increase brightness and Fn+End will decrease.

You can try the blue IBM-Access Key. In the Configure tab, you can manage the display settings.

If you cannot see your display because it is too dark, try attaching an external monitor via the vga connector.

I have a dell inspiron laptop, and a dell monitor hooked up to it, i turn on the monitor and it is very bright for about half a second then it becomes very dark, so dark that it looks like it turned off,...

Does the fault appear on the laptop screen aswell? It appears by your description that the fault is only on the external monitor. If the screen comes on for a moment and then goes blank as described, then this appears to be an invertor fault. It is very common among laptop and tft screens and requires the invertor inside the panel to be replaced / repaired. Simply plug the screen into another computer to confirm.

The screen on my HP Pavilion dv 1000 is too dark. The probem extends 2/3's from the left and almost 1/4 of the screen from the left. It's becoming so bad I barely can read the screen. Thre problem seems to...

If turning up the brightness hasn't helped then the lcd is likely going to fail soon.

option 1: hook it up to an external monitor.
option 2: Look for a replacement lcd on e-bay
option 3: Get a new laptop

HP will charge a lot for the display if they even still stock it.

Hope this helps.

Acer laptop has developed a fully dark screen

I am assuming that you have tried switching from external monitor output and local monitor. There should be a hot key on the keyboard to switch it. Also, try looking to make sure the driver for the display is up to date. I f it was update recently try rolling the driver back. If you need help with doing any of this post a comment. Hope this has helped some.

Monitor is very dark

I have to assume you have tried through existing means to change brightness and contrast.
These are generally provided for the user.

LCD screens are backlit via a fluorescent lamp. This is a high voltage device so the problem could come from either a failing lamp or the inverter circuit that drives it.

Access to the lamp varies greatly and to even check it may well be a job for a technician.
