I don’t believe in coincidences, so I would not think that you have the same issue in multiple areas. If it was just one, I would suggest taking the plates off and checking between them as well. But, since it’s affecting all, I doubt they are all bad. Perhaps concentrating on one TV. Can you take a cable out from KeyTV to one of your TV’s and then use a female to directly connect the cable to a TV using the coach wiring. This will prove that the coach wiring is good and eliminate the cabling as an issue. Also, is this a new issue?
