I have a PowerMac G4 (Quicksilver) that I configured at work using a CRT. Now when I connect at home to any of my LCDs, I get no display. I hear the startup tone, the drives are spinning and I can hear system tones eventually if I hit the esc key, so I know the system is booting.
But, no display! What can I do? I have tested on 2 LCDs at home and again on my CRT at work.
Here's what I have done since the last successful boot:
Installed an NEC DVD burner
Installed 512mb dimm.
The system did not want to boot with new ram, so I took it out, and now this problem. I have tried with and without the NEC DVD drive too.
This is driving me crazy. I have tried what I can find on apple's support area. I even reset the PRAM using the Control+Option+P+R, reset the logic board using the little button on it near the battery, and nothing worked. No signal at all to any monitors I have tried.
I don't have another Mac video card to try. I have a spare ATI Radeon 8500 64mb AGP, but it's the PC version.
Please help!!!

Nobody has any suggestions? This is one big expensive paperweight?

I'm not clear on whether it does or doesn't work with a CRT now, but anyway...
Did you try reseating the video card?

It does not work with any display. I have removed and reseated the video card and ram. I have tried each piece of ram that was in it before individually and together. I have removed all drives and reconnected. Nothing.

Might try Ctrl+Opt+Cmd+8 at home and see if you can force it into reverse video mode and kickstart it that way.
Maybe deleting the display preferences file?

I will try the first suggestion. The second, that could be hard since I can't see what I'm deleting.
Most suggestions I have received seem to point towards a dead video card. I don't know what could have killed it, but I will try to find one locally to test out at least.
