Has anyone ever seen/heard of this? I have recently aquired a G4 and only the top third of the LCD is displaying, then there is a third black, there is then a sinlge pixel line of diplay, then axactly a third black again. I measrued the gaps and they are axactly 70mm apart. I have a service manual and have seacrched the net 2 days looking for similar problems. I need to know if I should replace the diplay unit or if there could be a cable/connector type of issue? Please, anything, anyone?
