Question about Hitachi 43FDX01B TV
What you are hearing is the impending death of some component.
I see your post is old so I won't spend too much time on it.
Certain capacitors and semiconductors will produce this kind of noise when dying.
An intermittant solder junction can also do this.
It would take some signal tracing skills to locate the origin though I suspect you have already paid for the work or given up on the set.
