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.

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 72.
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.
Home Network
Symptom Remarks
1. I cannot connect the TV to the
network.
Go to the Setup > Network menu. Obtain the TV MAC address and
provide it to the router.
2. I plugged in a wireless USB adapter,
but the wireless connection is not
working.
The network may be locked. Go to Setup > Network. Highlight the
network name and supply the pass code.
3. The
INTERNET
key only goes to VUDU. Normal operation. The TV receives all internet services through VUDU
Apps. The TV does not provide full internet access as does a web
browser on a computer.
