Sure? It sounds not like a start, it sounds more like the
finish..or the end of the flyback transformer.
The symptoms you describe, to weide and dull image .getting wider while
warmup are those from a dead transformer.

Thanks, all, for the responses! The way it
measures out makes it look
like it may be an MJ10006 or similar. I think it's probably ok.
I poked around a bit more this morning and it's looking like part of the
flyback is shorted out -- we have a 2382 at the museum and I popped it open
just now and I verified that it measures differently (i.e "not shorted" :))
at the same points. So that's likely my problem. Drat.

And I was wrong -- the flyback's fine (yay!). Found a nearby 0.015uF, 400V
film capacitor that was shorted. Replaced it and now I have video! It's a
bit dim, it's too wide, and gets wider as it warms up but it's a start :).
Thanks again,
Josh
