Remote control problems
•
Ensure the remote control is set to the correct
device mode ( page 79).
•
Remove all obstructions between the remote
control and the TV.
•
Replace the remote control’s batteries ( page 23).
•
Your TV’s 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 82–87).
•
If the TV still does not act as expected, perform the
Reset Factory Defaults procedure ( page 45).
Channel tuning problems
•
Ensure the remote control is set to the correct
device mode ( page 79).
•
The Auto Tuning feature may have erased the
channel from memory. Add the channel to the
channel memory ( page 29).
•
The Lock feature may have blocked the channel.
Unblock the channel ( page 39).
•
If you cannot tune digital channels, check
the antenna configuration ( page 29). If
the problem persists, clear all channels from
the channel list and reprogram channels into
memory ( page 29). If the problem persists,
use the Reset Factory Defaults procedure (
page 45). See “TV stops responding to controls”
and “Other problems” ( page 70).
Closed caption problems
•
If the program or video you have selected is not
closed-captioned, no captions appear.
•
If text is not available, a black rectangle may
appear.
If this happens, turn off the closed-caption
feature ( page 36).

A closed-caption signal may not display
correctly under the following circumstances: a)
the videotape is dubbed; b) the signal reception
is weak; or c) the signal reception is nonstandard
( page 36).
Rating blocking (V-Chip) problems

If you forget your PIN code: While the PIN code
entering screen is displayed, press 4 times
within 5 seconds. The old PIN code is cleared (
