Don't know if this will help, but I had problems will all my TVs to begin with. I started checking the wiring and found that EVERY ONE of the coax connectors were loose!
On the TVs, on the antennas, on the back of the "A/B selector. Once tightened up, everything, (pictures and sound) was much better!
Then a tree limb on my street "removed" my platform antenna.
I purchased and had installed a satellite dish for the roof.
Now everything is soooo much clearer! And many more channels!! I just take my boxes from home on my trips and hook them to my TVs.
