Sound
Symptom Remarks
1. There is no sound even when the
volume is turned up. • Check if the MUTE key is on.
• The TV’s analog Listen to setting may be set to SAP (analog
program from the ANT input) but no SAP is being broadcast.
• Check that the Sound > Audio > TV Speakers option is set to On
to hear sound from the TV speakers. Possibly the TV Speakers
option is Off or set to Center but there is no A/V receiver con-
nected.
• If using an A/V receiver, check that the Sound > Audio > TV
Speakers option is set to Off to hear sound from the A/V receiver
speakers.
• Press and hold the POWER button on the control panel for 10
seconds to perform System Reset.
• The language selected in the Setup > Antenna Digital Audio
menu is not being broadcast for the current program.
2. The sound does not match the screen
picture. The TV’s analog Listen to setting may be set to SAP (analog program
from the ANT input).
3. The sound from my A/V receiver does
not match the screen picture (I should
hear the correct audio from my A/V
receiver). Check that • DIGITAL AUDIO OUTPUT and/or AVR/SURROUND
OUTPUT on TV’s connection panel is connected to the A/V
receiver.
Without this connection, devices connected only to the TV (and
not the A/V receiver) can be heard only from the TV speakers.
Note that this includes the
ANT input, a device (such as a
camcorder) connected to the TV, and any other device sending
audio to the TV only.
If using a NetCommand-controlled A/V receiver, NetCommand
•
may be selecting the wrong A/V receiver audio input. Check the
A/V receiver’s NetCommand setup in the
Inputs > AVR menu.
4. Cannot select an audio-only device; it
does not appear in the
Input Selection
menu.
Plug an unused video plug into the Y/VIDEO jack to activate Auto
Input Sensing. Assign the name CD/Audio or MP3 to make the
audio device selectable in the Input Selection menu.
. 5. Sound is coming from the TV speakers
instead of the A/V receiver. Connect the TV’s • AUDIO OUT to the A/V receiver.
Change TV Speakers setting to • Off or Center.
