Why is my screen black at startup?

crwdns2934249:0crwdne2934249:0:

I have a 17" iMac G5 (with ambient light detector) that powers up fine.  I can even hear the drive booting.

HOWEVER... the screens stays black.

I swapped a known good iMac monitor and the problem stayed.  (and the suspect monitor worked fine on another iMac)

I replaced the inverter board with another and still no joy.

Anyone have an idea what is wrong?

I do not see any bulging capacitors on the mother board.
