Well my mom finally did it, 6 months of leaving the television on almost 12 hours a day as background for the living room killed it. I've spent the last month poking around trying to find out why it made a loud pop and the brightness fell off sharply. Yesterday I got my answer. I powered up the set after replacing a few other parts only for it to flash a pinkish-purple on the screen and (gasp!) in the neck of the CRT. On another power up, only the green gun was working.

Luckily I have a replacement CRT lined up for it. My deadline for the repair is the first of January because we have a late Christmas party to host.

Here are a few pictures of the chaos in my living room.

Keep us posted!  I farm out my vintage TV repairs to a local guy I found on the antique radios forum.  I kind of wish I knew how to do it myself.

I'm no expert either(I can barely call myself a novice), I get a lot of advice from a friend who knows about this kind of thing.

The thing with TV repair is that you need a lot of extra test gear beyond a volt-ohmeter or DMM. For convergence, you need a pattern generator(I have a Sencore VA48 that does that and is also a sweep generator for alignment among other things). A high voltage probe is a necessity. It is also good to have a capacitor tester that has a high voltage(at least 100v) leakage resistance check function.

Used to have a TV similar to that one.With the generator connected to the TV its on life support.Have the TV test devices-but haven't used them in years.At least that RCA is "fixable"!Remember those late night purity and convergence sessions on my old set.Traded it in on a Sony Trinitron 27".
