Sound
Symptom
1. There is no sound even when the volume
is turned up.
2. The sound does not match the screen
picture.
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).
4. Cannot select an audio-only device; it
does not appear in the Input Selection
menu.
5. Sound is coming from the TV speakers
instead of the A/V receiver.
Remarks
• 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.
• If using an A/V receiver, check that the Sound > Audio > TV Speak-
ers option is set to Off to hear sound from the A/V receiver speak-
ers.
• The language selected in the Setup > Antenna Digital Audio
menu is not being broadcast for the current program.
• Press and hold the POWER button on the control panel for 10
seconds to perform System Reset.
The TV's analog Listen to setting may be set to SAP (analog program
from the ANT input).
• Check that DIGITAL AUDIO OUTPUT on the 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.
• Make sure the A/V receiver is set to the correct input.
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.
• Connect the TV's audio output to the A/V receiver.
• Change TV Speakers setting to Off.
