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
Try Now
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/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 the computer sound, connect the 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.
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 connections, check the signal information. A low signal level may
cause sound distortions.
Run Start Sound Test ( Settings Support Self Diagnosis Start Sound
Test).
