Don't turn the TV on ....

I do the same, but it is a sign of addition. I still use roof antena - more channels, would be like giving drugs to an addict.
My TV does not change anything, but I have it plugged into different outlet of the Furman Elite 20PFi conditioner. Try different outlet for TV, even with extension cord when it is far, because it might end up on the different supply phase (to isolate the problem). Check if your ICs or speaker cables don’t follow power cables. Make them cross each other at 90 deg, if you cannot keep them apart. Are your ICs shielded?
What type of tv do you have. I get issues with some tv’s and computer monitors if the settings are not set up I get head aches. Seems for me it’s a motion sickness thing and some monitors if set up with certain settings can induce headache even if it’s not a moving picture. Seems for me it’s a combo of refresh rates anti aliasing and a few other things. It’s more common in the gaming world but can show it’s self in tv monitors
TVs, telephones, smart phones, iPads, all of that kind of stuff is bad for the sound even when there’re not (rpt not) ON. That’s one reason why the sound is frequently so bad at shows, you know, with everyone standing around with smart phones in their pockets. And why demos sometimes fall flat on their faces. 😛
Since TVs probably dump a bunch of rf into the house AC and perhaps into the room, too, you could try a large ferrite on the AC cord and see if that helps. That’s a large ferrite, not a large ferret.
Large ferret might work as well - just try to wrap AC cord over it and soon you will forget minor problems with your system's soundI think you mean ferrite bead. Although maybe a large ferret might work. ;|
just fyi everyone.
i've a new apartment, and the tv and stereo (and several other lights, incl fluorescents and fans / dimmer switches) are all on the same breaker (15a).
the tv had an iso-tranny (1kva) but that clearly wasn't enough.
things improved markedly when i ran the tv, through the tranny, into a diff breaker.
(never liked trannys in series w/ the AC to the stereo).
might try some caps across the +/- for duplexes on the same breaker. more to come.
Stop watching FauxNooz and you'll feel relief almost instantly. Probably even pick up a few IQ points, too!
TV sound is already (still) compressed. You can try using a limiter/compressor for TV which can be set up to gate and then compress as it walks up to the limit you set, which can be soft or hard-kneed. IN a small place, knocking dynamics out helps a lot and it makes the sound of TV fuller. Some TVs also have SETTABLE compression rates, as do bluray/dvd players. Play with those. Set them too aggressively and they'll pump the noise up like a rerun of Rat Patrol!
For video, I use a Swiss Army Knife device, and it's TV, so true hifi is hardly a worry, a Behringer Ultrafex, which does a bunch of cool things. The model has been updated and expanded greatly over the years. For a couple hundred bucks, it's a great all around toy, can be useful as a noise reduction, an expander, peak unlimiter, soundstage toy, limiter, compressor, eq and some other stuff, and that's just my box. The newer stuff is far more crafty.
Behringer is a pro-audio company that doesn't rip people off. Sure, sure, there are better devices in every category, but they are like hifi: double the cost for a few percent more performance, unless you find there is a feature you must have.
It's cable news and talks shows and junk. Process the crap out of it and make it palatable.
Behringer is a good deal, lots of bang for the buck without trying to find and modify a mint dbx 119 which I used to have as my original go-to TV audio fixer upper until it was stolen.
Oh, and the Behringer stuff has knobs! Menus, too, but knobs! Who knew! Don't worry, it can be done.
I only use my TV to play movies. The rest of the time I am enjoying music on my stereo. Why invest all of this money in audiophile caliber equipment if you are only going to watch TV in your spare time? The common definition for insanity is doing the same action over and over expecting a different result. Break the cycle and save a ton of money on your cable TV bill, money you could put back into your system.
When I first bought a DLP Projector 20 years ago I plugged it in and the image drove me crazy. I could see the phase and I was so disappointed. I then realized the stereo was doing the same thing from the projector interference and eventually figured out it was a dirty power issue. This was my first foray into power conditioning and I bought a $200 Monster Power Center, which was big $$$ back then for me (yes I know branding and such, hadn’t found this site yet.) The image, colors, and sound never looked so good once it was in use and I had no more headache. If you are running your display on separate conditioned circuits change the refresh rate, you may also be seeing a discrepancy from the cable and the display’s rate. I suspect the display may not be synchronized with the output. You can force the two to be the same and that will give you the best results most of the time. Also I recommend turning down the brightness, they tend to be way too bright on the settings from the store.
While my Sundays are spent playing Audio all day. I love watching movies and shows at night. They both have a place, we are in the golden age of TV. There is a lot of great entertainment out there. Currently watching Altered Carbon on Netflix in HD with HDR. Awesome cinematography, plot, and I’m completely outdone that this level of quality is being produced in a subscription based service.
