Thank you all for the help.

I tried "rcpowersaved stop", it appeared to stop processes but the screen still
blanked after about 10 minutes.

I then tried "setterm -blank 0" and the screen did not blank, which is what I
wanted. So I need to do some more reading to execute this when the system boots,
but in the meantime I can manually turn off the blanking.

Thank you,
Kevin
