Q: iMac g5, no video output

I just replaced the logic board and power supply on my G5 imac, both of which were bad.  Now, when I power on, all three LEDs on the logic board come on, t there's no video output.  The video had been working fine before the logic board and power supply failed.

 

THe tech note says to try resetting the PRAM.  We have a wireless (usb) keyboard, and holding down option-apple-p-r doesn't seem to do anything.  Is there another way to reset the pram?

 

Any other suggestions would be welcomed.  Replacing

iMac, Mac OS X (10.5.8)
