You need to test the ibook with an external monitor to find out if the LVDS (video) cable or the logic board is the culprit. If you don't have the mini VGA to VGA adapter and you're located near an Apple store, bring the iBook in and ask a genius to connect it to a monitor. To check if the problem is software related just boot the ibook with an external source like the installation disk or a OSX firewire external drive or from another compatible Mac using the firewire target mode.
