SOURCE: two little white bright dots
these are lit pixels! which can only be caused by a bad dmd chip (the micro-mirror-device). the chip can be replaced but it requires an experienced technitian to align the chip so your picture is straight, centered and in focus.

You could have a defective screen - a defective inverter or a CCFL lamp.
To determine if you have a LCD screen or video card problem, read this and follow the instructions.
Defective CCFL backlight, it may have the following symptom:
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.
