I've just obtained another logic-board and recapped before it was fired up.
Fired it up - Happy Mac icon shows, then "Welcome to Macintosh" comes up, then the screen goes all black!!!! ( I would say just before extensions loads, at that point it goes all black - I haven't seen any extensions to load at all)
What could be wrong?
Cheers

Does it continue to boot after the screen goes black? Could be the backlighting failing

Also try booting with a good Disk Tools 7.0 or 7.1 disk.
Try a different power supply. Any Mac power adapter up to the original G3/iBook yo-yo power adapters will work (except for Portable, 1x0, 500 series, and 190/5300).
Do you have a Dock with external video capabilities? Try using it in that to see if it has the same problems.
