Sounds like there is a lot of dust on the crt, itself. This will cause a high voltage "snap" which I think you are hearing. This sometimes happens when there has been a spill of water or other liquid that has run or dripped down on the crt. Usually is not a problem if you turn the power off, unplug the cord from the wall outlet, take off the cover, let it set for a while( just to make sure the Hi voltage has drained off), disconnect and ground the hi voltage lead to assure drain down, then clean the dust off of the crt. Follow the dust off with a damp rag and wipe off all of the remaining dust that you can. Let things dry for a half hour or so. Reassemble and see how it works. I have had several $10 tv's that this process has worked well on. Each one lasted several years at least.

Oversized picture problem

Several possibilities, if you use a set top box to get your signal like a cable box or satellite receiver they will have settings that effect picture size. It could be a high voltage problem inside the TV causing an effect called blooming, if that is it you can usually change brightness and or contrast and see the picture get smaller and larger. I don't recall that set having any customer settings that could give that symptom.

02 silverado gas tank popping noise after startup & shutdown

It could just be the heat shield around your exhaust expanding and contracting again when your engine cools down. Sounds like a tin can type of popping noise?? If it is that's the heat sheild from the engine that protect's the spark plug wire and around under the truck cabin. Good luck and hope you find where the noise is coming from.

Loud popping noise

The 23" CRT set may have a high voltage breakdown in the flyback transformer or focus divider. Take the back off and operate the set in a dark room. Look for anything that has a blue glow around it or sparks flying when the pop occurs. I won't guarantee this will find your problem, but it is definitive if you see these!

I once had a set with these symptoms. I stopped the blue glow and arcing by covering the focus divider with epoxy. It worked for a couple of months before the divider literally broke apart.

Could be any number of things, none of them easy to diagnose. Unless your a TV repairman it's probably not worth fixing. It will cost tou more in repairs than a new TV.
