Flyback fire

[radio nut]

My crosley had the flyback catch on fire and destroy the entire set. Could something else have caused this fire, or is this solely a flyback issue? I did run this set about 200 hours and I figured it was free of flaws. I am asking so I can make sure this does not happen again. It has been a long standing dream of mine to have a tube tv. My crosley was it, now on my bench is a very old General electric set and I do not want another fire.Experts, please help!Thank you.
