Symptom
3. The A/V receiver is the selected audio source
but there is no sound.

There is no sound from the A/V receiver
for my DVD player or other surround sound
device even though I learned the IR code for
the A/V receiver's DVD input or other input.
(A/V Receiver Set Up for Audio-Only Switch-
ing)
5. There is no sound or picture from the A/V
receiver for my DVD player or other device
connected to the A/V receiver; the A/V
receiver should be sending video to the TV
over an HDMI cable.

Switching over HDMI)
6.
I've selected my DVD player or other sur-
round sound device in combination with the
TV speakers but hear no sound from the TV
speakers.
7. I "learned" the RECORD key for my VCR/DVR
but when I pressed the RECORD key, the
VCR/DVR did not record anything.
Remarks
• A/V Receiver Set Up for Audio-Only Switching
- Check to see if the A/V Receiver power is turned on.
- With A/V receiver power turned on, redisplay the Activ-
ity menu and press ENTER to allow NetCommand to
correctly select the A/V Receiver input.
- Incorrect setup in the Inputs > AVR menu. Check the
device connection assigned in the AVR menu.
• A/V Receiver Set Up for Audio and Video Switching over HDMI
- Check to see if the A/V Receiver power is turned on.
- If the device is connected only to the TV (e.g., on ANT
or a front panel input), verify that the TV's AUDIO
OUTPUT is connected to the A/V receiver.
- The A/V receiver is not switching properly because
you have not learned the IR codes for the A/V receiver
inputs to which your devices are connected.
NetCommand A/V receiver setup for the DVD player or digital
surround sound device or other device is not switching prop-
erly. See "Automatic Switching (Audio or Audio/Video)," page
60, and perform A/V receiver setup for a digital surround sound
device.
The NetCommand A/V receiver setup is not switching audio
and video inputs properly because you did not "learn" the A/V
receiver's IR codes for the device inputs. See "Case 3: Auto-
matic Audio and Video Switching via HDMI," page 62.
• A/V Receiver Set Up for Audio-Only Switching
If you have only an audio connection from the device to the
A/V receiver, a physical audio connection from the device
to the TV is also required.
- Connect the left and right audio output from the device
to the appropriate TV audio input. Now you can hear
audio from the device through either the TV speakers or
the A/V receiver.
- To switch audio sources, press MORE 9 (Audio), press
to show the Speakers option, then press to
select AV Receiver or TV.
• A/V Receiver Set Up for Audio and Video Switching over HDMI
With your DVD player connected to the A/V receiver, only
video is passed from the A/V receiver to the TV because of
copy-protection restrictions on the HDMI signal
Check that the VCR or DVR is receiving a signal directly from
your cable box or satellite receiver.
