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.
