Sound

Symptom

Remarks

2.

The sound does not match the screen
picture.

The TV’s “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 AUDIO

OUTPUT on TV’s main 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 convenience panel, 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 Activity menu.

Plug an unused video plug into the

Y/VIDEO jack to activate Auto

Input Sensing and make the audio device selectable in the Activity
menu.

.

5.

Sound is coming from the TV speakers
instead of the A/V receiver.

Disconnect headphones. Connect the TV’s AUDIO OUT to the A/V
receiver and select AV Receiver from the New Device Found screen.

NetCommand IR Control (NetCommand-equipped models only)
Symptom

Remarks

1.

Cannot see the menu from the A/V Receiver.

A/V Receiver Set Up for Audio-Only Switching

The A/V Receiver is not connected to any video input of the
TV. To check the A/V Receiver menu, temporarily plug into
an unused input of the TV, such as Input 3. Exit the New
Device Found screen and select Input 3 from the Activity
menu. Press MENU on the A/V receiver’s remote control.
A/V Receiver Set Up for Audio and Video Switching over

HDMI
Use the MENU key on the A/V receiver’s remote control.
A/V Receiver with

HDMI Control

Switch the remote control to AUDIO mode. Press the
MORE key and then 1 (Menu).

2.

NetCommand unable to learn specific device
keys.

A/V Device does not use IR format for remote control

signal. ITT and RF formats cannot be learned.
Room lighting may affect the signal. Have the remotes very

close (6 inches or less) to the TV during Learning.
If learning a Mitsubishi remote control, make sure mode is

not set to TV.
Some, but not all, device key functions can be learned by

NetCommand. For example, POWER and PLAY may be
learned, but other functions may not.
The signal from the remote control may not be strong

enough. Insert fresh batteries and try Learning again.
