You're confusing a consumer-grade TV with industrial equipment. Why do you think TVs have a hot chassis?

I have no idea what you are (mis)calling "flux" or "epoxy".
Typically you can't get a...

You may have dodged a bullet; you could have sacrificed more than just the cap and made the repair more difficult.

I have to report that I was wrong. The HDMI-to-VGA converter does pass a Blu-ray source (the latest Star Wars disc) at 1080i or 720p.

Maybe.
My first thought was that the video amplifiers and deflection circuitry would likely cause a smaller image as the device ages (i.e. underscan).
The CRT requires high voltages to...

In the Menu, under Channel, assign the "Channel Fix" to "Video 1".
You cannot then try to also skip Video 1, i.e. if you setup...

Incandescent light bulbs do not have the minimal attributes of a vacuum tube, i.e. having at least an anode and a cathode like a diode tube.

FYI there's a vacuum tube in your microwave oven.

Maybe that's possible, but it would require a perfectly focused electron beam with a really wide-bandwidth gun (i.e. fast turn on/off), and it could just look dim.
Ditto.

From my experience, I would disagree.
A side-by-side test of a Sony 27XBR15 (4:3 SD) to a KV-30HS420 (16:9 HD) (using a CECB as input) is my basis of comparison. By itself the the old SD TV looks...

I've seen that happen when you try to shrink the image size (i.e. vertical amplitude) too much in order to reduce overscan.

A 720p program can be just as large as a 1080i (eg. FOX versus CBS). ABC gives 720p a bad rep because it over-compresses its signal. But FOX does not.
