I find it useful to have a small TV I can move around to check things. That could quickly locate your problem. -- Mark Lloyd http://notstupid.us/ "It is possible to pay another man's debts on his behalf, but it is not possible to make a guilty man innocent by suffering in his place."

If the kitchen TV is digital, it can't have distorted sound due to the RF, unless there's bad video as well. If the item is 39 years old, it is analog and RF connection to 'central location' is certainly a suspect. If you have a second TV and a suitable F-connector attenuator box, you can swap in a known-good TV to see if that fixes the sound, AND flipping a few dB of attenuation into the RF can determine if you're near the noise floor with the wiring and splitters.

Or it might not find it at all. With the symptoms being described, one set may be more sensitive than another if it is a signal problem. How much does a small TV cost these days? They have to be pretty cheap. -- Rick C. + Get 1,000 miles of free Supercharging + Tesla referral code - https://ts.la/richard11209
