Sound (Troubleshooting)
First, perform the Sound Test to
determine if your TV audio is operating
properly. (Go to Support → Self
Diagnosis → Sound Test).
If the audio is OK, the sound problem
may be caused by the source or signal.
There is no sound or the sound is too low
at maximum volume.
Please check the volume of the device
(Cable/Sat Box, DVD, Blu-ray etc.)
