Where is the problem likely to be?...

[micky]

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.

Kitchen TV? Why?

Move it to another place and see.

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.

I see fancy brochures for 40ish megabuck houses on the lake with a
giant flat-screen TV on the wall in every room.

If you\'re always watching TV, you can do that in any cheap dump.

I find it hard to believe that a 20 year old TV will work at all on
modern digital TV signals without a set top box interposed somewhere.

My money for distorted audio would be on the audio amplifier circuit in
the set. Electrolytic capacitors seldom last more than a couple of
decades without degrading to some extent.

Signal related problems on digital are generally of the all or nothing
type due to the error correction and the image usually breaks up first.
Audio tends to get short gaps in and/or ultrasonic clicks depending on
the sophistication of the decoder (better ones mute bad blocks, crude
ones generate intense high frequency pulses instead).

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

That\'s what I was thinking. More along the lines of the signal amp causing audio to clip on smaller TVs with smaller speaker amps.
