You don\'t say if the distorted sound is only from the antenna, the DVD player or both. If one, but not the other, then that points you to the problem.. If both, that points in another direction.
If the problem is when using any source, I would suspect the multiple splitters. This is easy enough to test. A kitchen TV should be portable enough that you can take it to the room with the other TV and connect it to the cable feeding the TV that works well. If the kitchen TV works ok on the other feed, then the problem is the feed to the kitchen TV.
Why do you have so many splitters? Each 2 way splitter takes 3 dB from the signal and 4 way splitters take 6 dB from the signal. It doesn\'t matter if there is anything connected to the extra outputs.
Since this is a problem that developed over time, the signal strength may be marginal, but enough, except that there is a bit of corrosion on a connection or even inside a splitter.
I would replace any unneeded splitters with straight through connectors and see if the kitchen TV works ok.

All my tv\'s run off a central location, which used to include cable but
now has a DVDR with an amplified antenna that brings in my city and the
next one.
One tv is supplied a signal through a splitter/amp and a cable, and the
sound is fine.
The kitchen tv has lately developed bad sound. Words are intelligible
but sort of staticy or distorted. Sometimes it\'s worse than others.
Its signal is supplied through the same splitter/amp, another splitter,
another splitter/amp, and a long cable,
If you were a betting man, where would the most likely problem be, in
the kitchen TV (which is 20 or so years old), the cable, or that second
amp, which has been sitting on the basement floor and running
constantly, needing no attention, for 39 years?

Hi Micky,
The TV. Try moving it to the other location to check.

If there were a problem with the cable or splitter amp, you would be
seeing picture and sound disturbances possibly also on other outlets.

Why not? Watch the news while eating breakfast for starters. Have the ball
game on while cooking. You can even buy a refrigerator with one built in.

\"Staticy\" suggests an analog broadcast.
I\'d first check all the connections. A loose F-connector can have
profound consequences.

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.
Could just be a warped speaker cone; cooking steam and paper structure...

How much does a small TV cost these days? They have to be pretty cheap.

I find it useful to have a small TV I can move around to check things.
That could quickly locate your problem.
