I Can't Hear the Sound Clearly
When the TV has difficulties with sound, these steps may help resolve the problem.
Testing the sound
Settings Support Self Diagnosis Start Sound Test
If the TV plays the Start Sound Test melody without distortion, there may be a problem with an external device or the
broadcast signal's strength.
The problem Try this!
There is no sound or the
sound is too low at maximum
volume.
Check the volume control of the device (cable or satellite box, DVD, Blu-ray, etc.)
connected to your TV.
The picture is good but there
is no sound.
Set Settings Sound Sound Output to TV Speaker.
If you are using an external device, check the device’s audio output option. (For example,
you may need to change your cable box’s audio option to HDMI if the box connected to your
TV is using an HDMI cable.)
To listen to computer sound, connect an external speaker to the computer’s audio output
connector.
If your TV has a headphone jack, make sure there is nothing plugged into it.
Reboot the connected device by disconnecting and then reconnecting the device’s power
cable.
No sound is heard.
Check whether the Digital Output Audio Format is set to Dolby Digital+ in
Settings Sound Expert Settings Digital Output Audio Format. If you are using a
receiver that does not support Dolby Digital Plus, you will hear no sound when you select
Dolby Digital+.
The speakers are making an
odd sound.
Make sure that the audio cable is connected to the correct audio output connector on the
external device.
For antenna or cable connections, check the signal information. A low signal level may
cause sound distortions.
Run Start Sound Test ( Settings Support Self Diagnosis Start Sound
Test).
