Could be a broken backlight bulb, the inverter cable or the inverter board that may be bad. I worked on machines (mostly iBooks G4) that had been dropped with broken hinges and the inverter cable shorted in the hinge blowing a microfuse that protects the inverter circuitry on the logic board so if all other lightning components are in working condition then the microfuse can be the culprit.
