Zenith 19L25 Chassis Restoration - Advice?

[RitchieMars]

That's a good point, and it makes sense seeing that there's a small wire coming from inside the metal base that's soldered to the outside. There is a metal cage protecting this whole HV section, but of course it's on the topside of the chassis. I suppose that your Zenith serviceman would have known about the voltage present here, so I guess they saw no need to enclose it from the underside. I've tried to be careful around the HV section whenever I have the chassis running on it's side, but I did carelessly swing my probe past this area when I was taking some voltage readings and that's actually how I noticed the presence of HV in this area in the first place. A sudden zap from the base of the 1B3 caught me off guard, so I took note of that and later used the grounded screwdriver trick I use to discharge the CRT in order to confirm it.

I'm still going to be keeping an eye out for that HV leak, although it seems to be hiding from me at the moment. Perhaps another coat of RTV on the flyback will silence it for good. If this little nuisance will leave me be, I can get back to tracking down that contrast problem I've yet to cure as of yet.
