NetCommand IR Control (L75-A91)
Symptom
Remarks
3. The A/V receiver is the selected audio source
but there is no sound. 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.
4.
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) NetCommand A/V receiver setup for the DVD player or digital
surround sound device or other device is not switching prop-
erly. See “Case 2: Automatic A/V Receiver Switching to a Sur-
round Sound Device,” page 59, and perform A/V receiver setup
for a digital surround sound device.
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.
(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 “Case 3: Auto-
matic Audio and Video Switching via HDMI,” page 60.
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. 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
7. 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.
