Thanks for replying.
Not sure if I can relate that picture to an iBook?
I think it is no cable problem, I switched it already, same white screen.
When I take the cable there is a slight difference.
So it seems the image data is not transmitted properly through the cable.
I checked the connector, but it seems fine.
So either it is not or it is a logicboard issue I guess?
Someone here has the same, no fix though.
