Hi,
I hope anyone can help me here.
I have a powerbook G4 (400Mhz), which shows no video.
If I reset PMU, it will boot up just fine albeit the date and time reset.
But, whenever I power it off and try to start again, it would not show any video at all. I can hear for a while the HD makes noise, so the powering on seems OK. But then nothing happens. The screen stays black, no activity whatsoever.
Attempting to start from the system software CD does not work, either.

I thought it was the PRAM battery issue, so I bought a new one just now, but the problem continues.

Please help me what I should do. Is this a serious problem?

Thanks,
SJKIM
