Hi. I hope somebody in this forum can help me. I have a Powerbook G4 1.25gHz Firewire. I am running the Leopard OS recently updated. The other day this sight met me when I powered the machine Behind the screen everything seems to work normally. I have tried to reset the PMU and to connect an extern display. It didn't help. If you have seen anything like this before and knows what's wrong, I'd appreciate a reply. Thanks macand P.S.I'm new in here. Greetings from Denmark.
