How can I be sure that it is the flyback? I have had similar noises
coming from the flyback and it was caused by other components. Thanks.

Hopefully I'm wrong, but I suspect the flyback. I come
across this problem whenever I fail to get the hv
lines seated in those RCA splitters. Leaking hv in the
flyback would do the same thing.=20
