Assuming that you have checked all the audio settings, and they are correct
for your situation,
having one channel speaker physically out of phase with the other may cause
this problem.
If you can get to them, try reversing the leads on one speaker ONLY, as see
if the problem
goes away.

I seriously doubt that an out-of-phase speaker would cause anything like
what the OP is reporting. At most it would result in reduced volume.

Hi!

I believe you will find this is not a fault in the TV itself. You
should check the audio settings in the set to see if any of those
happen to be incorrect. I would recommend checking to make sure the
set hasn't been set to receive the secondary audio program (SAP) or
that any "effects" such as stereo expansion or the "smart sound"
effect are turned off.

If you are watching through a set top or converter box, have you
checked its audio settings to be sure they are correct? Perhaps the
box is outputting the wrong type of audio for the speaker system you
have.

This TV is probably capable of receiving stereo audio if it is being
broadcast. Some broadcasters--for whatever reason--have their stereo
audio messed up in the way you describe.

When you watch through the VCR, it's very possible that you are only
watching with monophonic audio, especially if the VCR is outputting to
the TV over its built in RF modulator. (Very few RF modulators output
stereo audio.) This may be enough to defeat any audio processing that
is being performed by your TV (most such schemes don't work on single-
channel audio) or problems with the stereo audio coming from the
station or source.

I've noticed that sometimes the effect of loud background noises and
quiet foreground noises can be caused by playing multi-speaker sound
(usually 5.1 channels) through a stereo speaker system.

William,
Thank you for your reply. I have experimented with the different settings
available through the TV menus and the CATV menus regard audio settings a
number of times. I again checked all settings; Smart Sound and other
processing is Off in the TV, though it is set on Stereo. Even set on Mono
the effect exists although it is slightly less noticeable over the poor
quality overall sound. The VCR is a hi-fi stereo model and is wired in
stereo using the RCA Composite jacks. Both the TV audio and the VCR audio
is processed thru the Bose 1-2-3 Home system (which is a 5.1).
(Alternately, I have turned off the Bose 1-2-3 and turned on the TV's
Internal speakers and the effect still exists on TV broadcasts but not when
tuning thru the VCR, played through the TV speakers.)

Thanks!
Scott

John,

Thank you for your reply. I am not using the internal TV speakers. All
audio is fed thru Bose 1-2-3 Home surround sound system.
Thanks!

Simple. It's the surround processing done at the broadcast that's
causing this. Two ways to fix:

1) Install a surround sound system making sure the center channel is
working.

2) Put the TV in mono mode.

To be honest, the physical separation of the speakers doesn't throw
much of a stereo soundstage anyway. When I repair or sell a TV that
isn't used
on a surround system, I always deliver it in "mono" All my TVs (not
on surround)
are in mono all the time. Trust me, you'll be much happier.

John,

Thank you for your reply. Both TV and VCR are outputting to Bose 1-2-3 Home
surround sound system. 1-2-3 does not have a separate center speaker but is
created using a wave channel from each of the side speakers. Stereo or mono
output from the VCR to the 1-2-3 does not have the effect. Only the mono or
stereo TV audio output to the 1-2-3 has the effect.

Even in Mono the background sounds/music are louder than the voices,
although the effect is slightly lessened.

Thanks!
