Hi everybody! I'm new to this post and I find it really useful. I recently bought an iMac G4 17" superdrive, but the screen is white. I mean that when I switch the computer on, I heard the "gong" sound, the monitor turns on but it becomes white! nothing happens anymore. I can't se the apple logo and the loading of the 10.4 operative sistem. Can anybody help me please? I think it could be the signal cable (because the power is working and the monitor is on). Am I thinking in the wright way? Does anyone know a link to disassemble the monitor stand in order to check the monitor cables? thanking you in advance, I look forward to hearing some answers. regards, dario.
