iBook G4 12" screen dim problems, please help!

Right my girlfriend put her G4 iBook down on a powerful magnet and the screen backlight went off. So I go about trying to fix it, so far I've changed the following

- Brand new Inverter cable
- Brand new Inverter board
- Brand new LCD screen!!

The picture is still backlight free I'm tearing my hair out, anyone got anything else I could try to get this bugger to light up again?
