SOURCE: my laptop screen is flickering
You most likely have a defective inverter that supplies high voltage to CCFL backlight. It is unlikely a faulty CCFL lamp because your laptop is approx 1yr. old.
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 the inverter or 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.
