# Where is the problem likely to be?

```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?

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.

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.

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.

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 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

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

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
