NetCommand IR Control (NetCommand-equipped models only)
Symptom
1. NetCommand unable to learn specific device
keys.
2.
The A/V receiver is the selected audio source
but there is no sound.
3. 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.
(A/V Receiver Set Up for Audio and Video
Switching over HDMI)
4. 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.
5. 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 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.
• 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.
• The key was "learned" correctly but can be accessed only
from the Tools 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 and the
correct key has been "learned."
- 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.
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 "Automatic
Audio/Video Switching Over an HDMI Connection," page 69.
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.
