RE: Isolate the TV AC power from the other stuff, so IMO yes a Triplite might work.

Update: yes it's a Samsung. The noise is coming from the screen, which is drowned out by the audio. The issue is the same noise is being amplified through the speakers. Having reviewed the link Duster provided, I adjusted the picture settings, finding that the only adjustment that changed anything was the "eco" settings. "high" eco, which dims the screen did change the pitch of the noise to something a little more tolerable.
In the eco settings, there is an option for "screen off", but leaves the TV itself on. This setting eliminates the noise completely.
So that would indicate its not a grounding issue, no?
Just the screen generating noise and getting back on the line.
Forgot to mention, there is a vertical line on the screen which means the screen is indeed pooched. its hardly noticeable while playing a movie.
But I think I'll be on the lookout for a new TV rather than an isolation device.
