Turn the printer off for a minute to allow to reset, then turn on main switch and try. If still do not work, then turn on secondary power and try. One of the two should work for you.
Thanks it worked! Whew! With the other issues I am having I was worried this meant my main board was screwed for sure. Now I can go back to the plan of changing the cables first. If I have to get a new main board I can change it out myself easily by putting back the parameters on the new board. IF it gets to that.
