Chapter 7: Troubleshooting
Remote control problems
• Make sure the remote control is set to the correct device
mode (- page 19).
• Remove all obstructions between the remote control and
the TV.
• The remote control batteries may be dead. Replace the
batteries (- page 17).
• The TV remote control may not operate certain features
on your external device. Refer to the owner’s manual for
your other device to determine its available features. If
the TV remote control does not operate a specific feature
on the device, use the remote control provided with the
device (- pages 19–23).
Channel tuning problems
• Make sure the remote control is set to the correct device
mode (- page 18).
• The channel may have been erased from the channel
memory by the Add/Erase feature. Add the channel to
the channel memory (- page 27).
• The channel may be blocked by the Channel Lock
feature. Unblock the channel (- page 41).
Closed caption problems
• If the program or video you selected is not closed-
captioned, no captions will display on-screen
(- page 37).
• If text is not available, a black rectangle may appear on-
screen. If this happens, turn off the closed caption feature
(- page 37).
• A closed caption signal may not display correctly in the
following situations: a) when a videotape has been
dubbed; b) when the signal reception is weak; or c) when
the signal reception is nonstandard (- page 37).
