A couple things to try:

1st check the backlight settings

Turn on Backlighting and Control Brightness To use your device in dark environments, enable the automatic backlighting feature:

  1. From the Jump screen, press MENU no backlight - t02003-15.gif then select Settings > Battery & Display.

  2. In the second group box, select the Turn on backlight when using device check box.

  3. Highlight, then select the Brightness slider to open it for editing. Roll the TRACKBALL right to increase brightness; roll the TRACKBALL left to decrease brightness. After you've made the adjustment, press the TRACKBALL to exit edit mode.

  4. Select the length of time you want backlighting to stay on from the Turn off after pop-up menu.

  5. To use the device's light meter while the backlight is on, select the Use ambient light sensor check box.

  6. Press JUMP t02003-14.gif to return to the Jump screen and save your setting.
Now, when you press any button or key, or flip open the screen, backlighting will turn on for the set amount of time. Note that as long as you press a key or button before the set time elapses, the backlight will stay on.
Tips:
  • Even if you have not selected automatic backlighting, you can turn on backlighting at any time by pressing MENU + . The backlight will remain on for the time specified in the Backlight Turn off after pop-up menu.

  • When in key guard mode, you can turn on the backlight by pressing theno backlight - t02003-66.gifSHOULDER t02003-66.gif button.
If it still does not work, then you can try resetting the flex cable to the lcd.

Reseat the SidekickFlex cable

If that doesn't fix it then a new lcd assy will take care of the issue. they run about 45 dollars on ebay.

How do I know if my backlight on my LG tv is working
Wait until it is very dark. All lights out. Switch on. The screen should perceptibly change from black to dark grey. Perhaps you will see some light leakage near the edges where glass meets plinth.

And there is the T test where you touch the screen with the back of your hand after it's been on for a while. Although LED backlights are cold, they do generate some heat. So a perceptible change in temperature usually indicates that the backlight is functional.

Backlight spoilt for dsc t90
When the display is to dark or to light, the manual says:
Adjust the brightness of the backlight (page 18).
On page 18 it says:
This sets the brightness of the LCD screen. When viewing images in bright outside light if [Brightness] is set to [Normal], reset to [Bright]. However, the battery power may decrease faster under such condition.
You also can press the button with the > logo, to change between view pictures and record.

Monitor is dark. how to fix?
Walt, hold the Fn key down again, and tap once more on the Acer, F5, Display Toggle-Over key.

There are at least 3 display options available;

1) Internal display of laptop ONLY

2) Internal display of laptop AND external display

3) External display ONLY.

Were you just using the external display for more 'display real estate room', or was/is there a problem with the internal display of the laptop?

Was no problem? Is now? Even when using the guidance stated above for the Fn and F5 key?

Then if your laptop uses a CCFL for a Backlight, it also uses a screen Inverter. Screen Inverter is bad.

If it doesn't use CCFL/s for a backlight, and uses LED backlighting, replace the LCD screen.
The LED backlighting is incorporated in the LCD screen assembly, and you ain't replacing it.
Replace the entire LCD screen.

Post the laptop manufacturer name, and model number in a Comment. Model number is on Bottom of laptop.

OH I'M JUST KIDDING!

My brightness control does not work just turned on and can not hardly see anything it is up and running what now
Have you tested it with an external monitor?

I would say you either have a damaged inverter board or screen baclight lamp. Usually the inverter board fails in one of the following ways:

1. When you turn on the laptop, the screen lights up for a short period of time and then goes dark. You still can see an image but it is very dark, almost invisible and definitely not usable. When you restart the laptop, the screen lights up and then goes dark again. The laptop works fine with an external monitor.
2. Your laptop turns on but the screen remains dark all the time. You still can see a very dim image outline. The laptop works fine with an external monitor.
3. The laptop screen works fine for hours or even days, but sometimes it goes very dark as it mentioned above. When you restart the laptop, the screen works fine again.

Inverter failure symptoms are very similar to backlight lamp failure symptoms and in most cases you cannot tell which one is causing the problem until you replace either the inverter board or the backlight lamp. From my personal experience, inverter boards fail more often than backlight lamps. If you have to guess, replace the inverter first.

Screen is dark or dead on my 17" Macbook Pro
This could be a backlight issue, a board issue or an inverter issue. Look at the screen closely, if there is a faint image it's either a backlight issue or inverter issue. To weed out between the two you can just order on inverter, they're 20 bucks on ebay, if that doesn't work, replace the backlight. Backlight repairs are somewhat difficult. As much as I would like to be able to tell you a quickfix that will solve backlight the problem, you'll most likely have to google for guides that show you exactly how to replace the backlight or bring it in for repairs.I work for Mac Repair NYC and i have to fix this problem a lot.

Dark screen ,fn does not work
I would suggest connecting the laptop to an external monitor, just to make sure that it is all running correctly.

If you can see a very dim image on the screen then the backlight is out. This can be a light problem or the inverter that powers the backlight could be bad. The inverter is not real dificult to change and also is not very expensive. If it is the backlight tho, it is easier to just change out the entire screen.

Hope this helps

Dark screen
if the picture is REALLY dark, like you can just barely see it in a lit room, then the backlight might not be lit. LCD TVshave backlight that shines through the LCD screen which allows you to see the picture.

If it's not the backlight then it would be the brightness/contrast settings that need to be adjusted. If the picture used to be normal and all of a sudden went dark, verify the backlight. Normally you can look through the slots on the top of the set and determine if the backlight is on. If you can see a bright light through any of the slots, the backlight is probably OK... go after the brightness/contrast settings.

Display light is dark
I have seen this problem before this is caused by a failure of the backlight which provides illumination for the LCD screen. You may also want to check the inverter also since it fails often and interacts with the backlight.
