okay, i am a total dumb a@@!

when I swapped power supplies I did not fully engage the cable that connects the CRT to the AB.  Upon opening the machine this evening (I was going to located cap C15 and replace), I noticed that the cable was not connected and just dangling.  I plugged back in, started up and all is well again.   

So this problem is solved and was user error.  Guess you can't get a display if it's not connected to anything! :0

Thanks for all of your help!
