On start up of Williams Cyclone fuse F1 1/4 amp blows. I've disconnected 3J5 the Display Power and 3J6 Logic Power. The fuse still blows on startup. If I am following the trouble shooting guide correctly, my problem then is on the power supply board. Is this correct?

That is correct, unless for some reason the transformer has gone bad, which is very unlikely. My guess is Q1 or Q3 is kaput, but it could be anything in the high voltage circuit.
