2. The sound does not match the screen
picture.
The TV’s Listen to: setting may be set to SAP. See page 41.
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 AUDIO •
OUTPUT on TV’s back 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 1/ANT 2 inputs, a device (such
as a camcorder) connected to the front panel, and any other
device sending audio to the TV only.
Check A/V receiver input selection in the Inputs > AV Receiver •
menu.
If NetCommand is set up incorrectly for the A/V receiver,
see “A/V Receiver Control: Automatic Audio Switching,” page
59.
4. The sound from my A/V receiver does
not match the screen picture (my source
device should be sending both audio
and video through the A/V receiver).
Check A/V receiver input selection in the Inputs > AV Receiver •
menu.
If NetC
ommand is set up incorrectly for the A/V receiver,
see “Setup to Control Automatic Audio and Video Switching via
HDMI,” page 62.
The TV’s •
Listen to: setting may be set to SAP. See page 41.
5. Cannot select an audio-only device; it
does not appear in the Input Selection
Menu.
Plug a video plug into any composite
VIDEO
jack for the Auto Input
Sensing screen to appear. See “Audio-Only Device,” page 25.
