Where is the problem likely to be?...

The kitchen tv has lately developed bad sound. Words are intelligible

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?

Should I assume that these signals are all digital?

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.

Hi Micky,

The TV. Try moving it to the other location to check.

maybe it\'s a massive crt set puttied into a big hole in the wall. There must be some reason he hasn\'t checked that already.

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

I think there is/was a microwave oven with similar \"front panel\".

With LCD and OLED displays being so cheap, expect to find them
on all sorts of \"surfaces\". Maybe the bathroom mirror will be a
display with an out-facing camera... show folks how they will look
in various lighting conditions (e.g., applying makeup -- thie is what
you\'ll look like in the office lighting, later in the restaurant
or club, etc.)

With the *exception* of the bathrooms, we have one in every room
(though they are technically just \"displays\", relying on media
sourced from the home network for \"content\".

You\'ve not said WHICH city or given any other indications as to the
type of broadcasts.

\"Staticy\" suggests an analog broadcast.

I\'d first check all the connections. A loose F-connector can have
profound consequences.

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.

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

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

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.
