Start Sound Test
If the TV plays the

 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.

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+

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.
