My 15 year old CRT TV won't display images

Now, before you guys say it's old and take it a rest, it was working a while ago but then lately when I turn the main power on, more amount of static is emitted than usual and makes a noisy ticking sound followed with rgb lines on the top most pixels getting brighter overtime. Then when I turn it off, it makes a burning, sizzling sound.

All electronics work perfectly.
Right up until the moment they don't.

Your monitor has reached that point.

It sounds like it's probably a combination of a power supply problem (unfixable unless you know a vintage tv repairman, or have experience in HV DC circuitry), or it could use a degaussing. I found this link: https://itstillworks.com/degauss-sony-television-2256.html. Trinitrons are tuned from the factory, and have a weak internal degaussing, which can be sometimes triggered by the procedure described in the link. There isn't a whole lot you can do with CRT's unless you know your way around HV DC power supplies.
