Hi!
If you know what you're doing inside a TV set, or at least know what to
stay
away from, then open it up and have a look. Try disconnecting the
speakers
and seeing if the noise goes away.
It is possible that the noise is not coming from the speakers. Some
cheaply
designed/defective/overloaded power supplies can make noise when
operating.
Since your TV is probably a fairly modern unit, the low voltage power
supply
probably runs all the time...and that's why you hear the noise.
If it is power supply noise and nothing seems to be wrong with the set,
it
may just be something that the TV will have throughout its useful life.

Further to the last posters advice, before you open it up, just turn the
sound right down to zero with the remote and see if the noise stops. :^)
If the noise stops, the problem might be a bad cap in the audio amp or its
power supply.
If the noise is still there, it could be a buzzing transformer winding.

sets are not the best engineered units out there.

Hi there, thanks for the replies - Id call myself a hobby electrician, fix
all my own auto/whitegoods/home appliances as and when, I did electronics at
school, electrical engineering at college, work in computers now- not much
to solder in a PC tho :-) TVs are odd tho, never learned to repair them but
yes I know what to stay away from (most of it tbh).
ok it goes like this.
Muted or Position 0 on volume - No buzz, total silence
Position 1 - Buzzzz starts and continues at same level until 4 5 6 the sound
comes in louder and begins to overpower the buzzzz (which doesn't go away,
just is in the background)
And its definitely coming from the speakers and not a transformer buzz. Its
annoyed me for years and as said, Bush isn't the best of makes but the
picture is so very clean and still sharp (I'm not a 'everything set to 11'
person) just the sound is utter rubbish.
Anyway, Id welcome any ideas to shut it up.
Thanks
