Symptom Remarks
1. TV Guide On Screen® system shows no
program listings.
• Program listings are downloaded while the TV is off and the
cable box is left on. It may take up to 24 hours to begin to
receive TV program listings. It may take up to one week to
receive all eight days of TV program listings.
• Invalid ZIP code was entered at the initial TV Guide On Screen
system setup. Select NetCommand from the main TV menu,
then Guide and enter the correct ZIP code.
• Check the connections between the TV and the TV Guide On
Screen input (cable, antenna or cable box and IR cable). At
least one antenna connection must be associated with the TV
Guide On Screen system to receive program listings.
• When using CableCARD™, the cable company may have
converted the TV Guide On Screen host channel to a digital
format and lost the information. Connect an antenna to
ANT 2 and memorize the antenna channels in the TV Setup
menu. Add ANT 2 to the TV Guide On Screen setup in the
NetCommand menu. You may be able to download from the
antenna information for both cable and antenna.

system manual for instructions on the Setup Service.

tion menu, open the NetCommand menu, and select Learn.
See chapter 3, “TV Setup.”

Symptom Remarks
1. Cannot see the A/V Receiver menu.
The A/V Receiver is not connected to any video input of the TV.
To check the A/V Receiver menu, temporarily plug into an unused

and select Input 3 from the Input Selection menu. Press MENU.
2. NetCommand unable to learn specific device
keys.
• Device does not use IR format for remote control signal. ITT

• Room lighting may affect the signal. Have the remotes very
close (6 inches or less) to the TV during Learning.
• 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 batteries and try Learning again.

source but there is no sound.
Check to see if the A/V Receiver power is turned on. After the
power is turned on, redisplay the Input Selection menu and press
