if you find out the power line (cummonly an line that is gnd if switched on and n/c if turned off). then you connect the leds with this line or you attach an external switch and connect the leds directly to the battery contacts.
NOTE: YOU WILL LOSE YOUR GARANTEE IF YOU OPEN THE CLASSPAD!!!

you can try it yourself . Here are some links to other calculators/handhelds that people have added backlights for...
Basic example using a TI.
These plans are pretty general, which means they could be easily be applied to a Casio calculator. Of course it also means you need to figure out the specific stuff yourself.
HP 200LX palmtop (made ~1995, long since discontinued)
This web page applies to the HP 200LX, but again it could be applied to the Casio ClassPad. This web page has some really good pictures illustrations, a must read if you plan on trying this.
This company that offers a generic backlighting kit (the one used in the HP 200LX example above). They pretty much just sell you the parts.

I've take apart my PV and now I'm trying to find out how its backlight works.

A backlight?.... it is an illuminated display. The LCD on the ClassPad doesn't have the best contrast. A blacklight is a series of LEDs (light emitting diodes) that shines light from behind the display.
what is it for??
Check out an example below to see what a difference it makes...
