You could have a defective screen - follow this to determine the fault.
Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.
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.

Hey, I've just been having this problem. Try pressing CTRL + SHIFT + FN all at the same time. I found out that I had to press them once to turn on the green keys, and then press them twice more to turn it off. I hope that works for you.
