Focus jumper is the only one I have heard of in a 25" color.
Stupid idea. Also I cant see having 6KV on the PCB. Hints
at the CRT being a low focus tube but again never seen one
bigger than 19".
For convergence look for very small electrolytic on panel. The 19" sets
had one threw the blue off IIRC. If not try turning the bright &
contrast down in darkened room & try it. If its better the CRT
is probably weak. Once you get the feel of a delta tube center
convergence falls into place in seconds without a pattern.
Side and T&B take some time often.

I have been messing around for a while with the convergence/greyscale of this tv, and I gotta say this one does not let itself converge easily. On both my zenith it was rather easy, on this one it's almost impossible to get an acceptable one (acceptable for me that is!)
Another thing I find mildly annoying is the focus "selector". You can see it in the top right corner of the right board. This one doesn't use a potentiometer but an 8 position focus pin. I can't really see how this setup can give you the best focus possible out of this tv because the sweet spot is probably midway between 2 adjusments...maybe I could stick a potentiometer in series with the focus pin to be able to fine tune it?
