GUIDE Plus+ System Problems
GUIDE Plus+ setup won’t turn off tape for VCR setup and/or channel 02 cable box
• Check to see if the G-LINK wands are positioned correctly in front of components’ remote sensors.
• GUIDE Plus+ system control of cable box is slower than direct control of the box itself. Keep this in mind when changing channels.
•You may have an incorrect GUIDE Plus+ Channel Lineup. The guide may get out of sync with the cable provider. Use the GUIDE
Plus+ Setup in the GUIDE Plus+ Menu to change the zip code to 99999. Turn the TV off for 10 minutes. Use Setup again to change
the zip code back to the correct value. If asked, be sure to select the correct channel lineup from the on-screen list.
Program information doesn’t download
• Review your setup information and make sure it’s correct. Press MENU on the remote and select GUIDE Plus+ System menu and then
Setup. Go to page 47 for detailed instructions about the GUIDE Plus+ Setup menus.
• The TV must be off to download information. Leave your TV off overnight, for at least 10 hours, to receive the initial download for
your area.
• If you’re using a cable box, leave it on so you can receive program information.
• The GUIDE Plus+ system doesn’t display program listings for satellite TV.
Scheduled Watch or Record doesn’t occur
• Check Schedule for timer conflicts. Go to page 46 for instructions.
• Make sure the wands of the G-LINK cable are placed in front of the remote sensor(s) on the component(s).
• Make sure your VCR is turned off during the time you’ve scheduled to record a program because the system turns the VCR on when
it starts recording (if it’s already on when recording starts, the system will turn it off).
