Honestly Sigma7 you are a rock star!

I have another question for you when I tried to turn it on.  There is no front bezel switch and there is two wires green and white.  If I connect those would that by pass the front bezel switch?

front bezel:

two wires:

The green and white wires under the left side of the CRT go to the front panel safety interlock switch, which is missing in your picture (along with the plastic holder).

IIRC, connecting them would have the effect of preventing turn-on, and so you want them disconnected if there is no interlock switch to activate.

OK so leaving it disconnected and making sure the back connector on the PSU is engaged (or the back cover is on), there should be life. 

There isn't but I think I need to watch Adrian's videos and again and check the cable I made to the motherboard.  I made a 60pin cable.  Is there another way to test it by passing the on button/or soft switch?

Do you recommend doing a bench controlled testing like Adrian has done also?
