My second tv is connected by a Bush digibox - no recorders etc. Over the past number of weeks the sound on the tv is becoming weaker and weaker. At full volume now the tv is just about able to produce a sound which we are able to hear providing there is no other noise!
P.S. The tv is probably a 10 year old Hitachi.
One way of locating the cause would be to connect the digibox to your other TV and use. Alternatively, use another video aor udio source, such as a VHS or DVD player with the second TV. New digiboxes are quite cheap as are secondhand TVs.
