Sound problems
Screen display is on but there is no sound.
Check other TV channels.
[Depending on model] Ensure the TV Speaker is set to On.
For an analogue broadcast, stereo is not clear or sound comes from one speaker only.
In a poor reception area (areas with weak or unstable signals) or if Multi Audio is not stable, select Mono
on Audio.
Adjust the Balance using the Navigation Button.
TV sound is not in sync with the image or the sound breaks up occasionally.
If the issue affects a specific TV channel only, it may be caused by problems with the broadcast signal for
the individual station. Check with the TV station or your cable operator.

On certain programmes, there is no sound at all, or only the background music can be heard (in case of
