turn off the monitor and unplug the power cable, and reconnect the monitor, then
try again.

If it doesn't work,  try to use a different monitor to see if there is a problem with the
monitor itself.

The next thing you can try is to reset the NVRAM, by try in <Stop> N key

hold down <Stop> N keys while you turn the power on for a few seconds, see if it can help.

It could be memory, or CPU or mainborad or graphic card or NVRAM chip problem.

try to re-sit the memory to see if it can help.

if you have another Ultra 10 or Ultra 5, you can try to move the HD to the Ultra 10/5
boot it up and check /var/adm/messages file to see if any error messages.

You can also swap the NVRAM chip to see if you need a replacement.
(ps: the NVRAM in Ultra 5 also works with Ultra 10)

Please read the Ultra 5/10 service manual:

Before open the box.

the memory!  i reseated the memory and held my breath...on powerup i had video.

thank you!

i had no idea...the manual states that there could be a ´hardware problem´ which leads to a conundrum of which where and what.

thanks again for directing me in a good direction
