Chapter 8: Troubleshooting
Remote control problems
• Make sure the remote control is set to the correct device
mode (
-
page 21).
• Remove all obstructions between the remote control and the
TV.
• The remote control batteries may be dead. Replace the
batteries (
-
page 20).
• Your 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 your TV
remote control does not operate a specific feature on another
device, use the remote control that came with the device
(
-
pages 26–32).
• If the TV still does not act as expected, use the Reset Factory
Defaults procedure (
-
page 40).
Channel tuning problems
• Make sure the remote control is set to the correct device
mode (
-
page 21).
• The channel may have been erased from the channel memory
by the
Channel Add/Delete
feature. Add the channel to the
channel memory (
-
page 37).
• The channel may be blocked by the
Channels Block
feature.
Unblock the channel (
-
page 55).
• If you are unable to tune digital channels, check the antenna
configuration (
-
page 36). If you are still unable to tune
digital channels, clear all channels from the channel list
(
-
page 37) and reprogram channels into the channel
memory (
-
page 36). If you are still unable to tune digital
channels, use the Reset Factory Defaults procedure
(
-
page 40). Also see “TV stops responding to controls”
and “Other problems” (
-
page 65).
Closed caption problems

happens, turn off the closed caption feature (

following situations: a) when a videotape has been dubbed; b)
when the signal reception is weak; or c) when the signal
reception is nonstandard (
