You should have a Function key bottom left on keyboard and another key like right hand arrow with a picture of a sun on it, so press Fn and the sun at same time, that may do it.

You can brighten or dim the LCD screen by pressing the Fn key plus another key with the a sun symbol eg the UP & DOWN arrow keys or one of the F3 to F12 keys - it varies depends upon the model of the laptop.
If you cannot vary the brightness of the LCD screen the you have a faulty backlight.
Connect an external monitor to the laptop and power it up, if you see a clear image on an external monitor, this means your video card is OK.
If you see a dim image or flicking image on the LCD screen it means you have a backlight problem.
Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.
