other than checking all the parts its hard with out a scope. feel for cold resistors (esp large ones) same with pots (they get warm), lastly the diode pack may be bad.
This is what I try to avoid part replacement to fix a problem, sorry if it sound negative, it just a hard way to fix things. |

well there is a vert pulse and a Horz pulse so you just setup so you can see them. you bro should know for his scope where those are.
if the blue coil does nothing don't over look the convergence cluster itself, check the coils for continuity where they terminate at the convergence board |

Davewm has you on the right track. All the waveforms are shown on the
conv socket if you got the sams. Convergence probs are rare, tube zeniths had diode packs go & left blue pots. your biggest hint is if any controls dont work or barely work. And dont forget you often have to go back & forth allot sometimes inc. the middle. BTW the right is always the hardest. 73 Zeno |

It seems the blue pots are moving things around, but whether they are doing it as designed, that's another story. I know there's one pot that isn't doing much when turned, but I forgot to note it and now have to find it again. I don't know of any way to test the diode pack.
