My TV is about 11 years old, it's a 32 inch tube Toshiba. It's a model
CF32G50, manufacture date, August 1997, and the chassis number is TAC
9715.

The distortion is sort of like half circles on both sides of the
screen, with "rays" that "flutter". The middle of the screen is
brighter, but can only really see that if I have a solid light color
background, such as a webpage displayed, or a menu for the DVD player.

I could see the pattern at times even when watching regular TV when I
first bought it. I called repair out twice after purchase and they
couldn't find anything "off", so I had this problem the whole time I
had the TV.

Now that I'm using the TV also to display my computer, it's really
bringing the defect out, especially on static screens where one color
dominates. Very irritating. Not absolutely sure, but I think my TV
may have an automatic degausser built in. The TV has never been
dropped or damaged, and I've had the TV in about 5 different houses
now.

I linked a crude drawing as it's about impossible to take a decent
picture of a TV screen, link below.

Any info helpful if it's something that can be taken care of
reasonably easy. Thanks much.

Its really hard to tell much from your sketch, but I'd check the degauss
posistor - sometimes the internal thermistor pellets crack or shatter
causing all kinds of mischief.

The most common type has 2 elements, both PTC thermistors, one is in series
with the degauss coil so as it self heats and increases resistance the AC
current through the coil decays. The other NTC pellet is directly across the
switched AC so it additionally heats the degauss pellet effectively
switching it off.

There is another rarer 3 pin type - one of the pellets is NTC and is in
series with the AC feed to the bridge rectifier.

Some modern TVs have a similar degauss posistor to monitors - a 2 pin single
element PTC controlled by a relay.
