NetCommand (Y an d 734 series only)
Symptom Remarks
1. Cannot see the men u from the A/V Receiver.
The A/V Receiver is not conn ected to any video input of the TV.
To check the A/V Receiver menu, temporarily p lug into an unused
input of the TV, such as Input 3. Exit the Auto Input Sensing scre en
and select Input 3 from the Input Selection m enu. Press MENU.
2. NetCommand un able to learn specific device
keys.
• Device does not use IR format for remote control signal. IT T
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 Lear ning.
• If learning a Mitsubishi remote control, make sure slide
switch is not set to TV position.
• 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 batterie s and try Learning again.
3. The A/ V Receiver is the selected audio
source but there is no sound.
• Check to see if the A/V Receiver p ower is turned on.
• With the power turned on, redisplay the Input Selection
menu and press ENTER to allow NetCommand to correct ly
select the A/V Receiver i nput.
• Incorrect setup in the Inputs > AVR menu. Check the
device connection assigned in the AVR menu.
4. There is no soun d when I switch to the A/V
receiver using the Speaker setting in the
AV menu, even though I have physically
connected the TV to the A/ V receiver and
learned IR codes for the receiver inputs.
Wrong input or no input was assigned in the AV Receiver Learn
screen. All audio should go to the A/ V receiver as audio output
from the TV unless the device’s audio is connected direc tly to
the A/V receiver. See chapter 6, “NetComma nd,” and perform
the procedure to select the correct A /V receiver input.
5. There is no soun d 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.
NetCommand A/V rece iver setup for the DVD player or digital
surround sound device or other device is not switching prop -
erly. See chapter 6, “NetCommand,” and perform A/ V receiver
setup for a digital surround sound device.
6. I’ve selected my DVD player or other sur-
round sound device in combination with the
TV speakers but hear no sound from th e TV
speakers.
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 au dio output from the device to the
appropriate TV audio input. Now you can hear au dio from
the device through either the TV speakers o r the A/V receiver.
• To switch audio sources, press AUDIO, press to show the
Speakers option, then press to sele ct AV Receiver or TV.
7. I “learned” the R ECORD 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 fro m
your cable box or satellite receiver.
