NetCommand IR Control (NetCommand-equipped models only)
Symptom Remarks
1. 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.
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.
2. The A/V receiver is the selected audio source
but there is no sound.
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.
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)
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.
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.
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
5. I “learned” the
RECORD
key for my VCR/DVR
but when I pressed the
RECORD
key, the VCR/
DVR did not record anything.
Check that the VCR or DVR is receiving a signal directly from
your cable box or satellite receiver.
