HOME ➾ Settings ➙ SUPPORT ➙ Sound Test

First run a Sound Test to verify that the sound signal output is normal.

If there is no problem with the test sound, check connected external devices and

the broadcast signal.

Problem Solution

Screen display is on but there

is no sound.

• Check other TV programmes.

• 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

Multi Audio.

• Adjust the Balance using the Navigation button.
