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 30).
The channel may be blocked by the Channels Block
feature.
Unblock the channel (
page 47).
If you are unable to tune digital channels, check the
antenna configuration (
page 29). If you are still
unable to tune digital channels, clear all channels from
the channel list (
page 31) and reprogram channels
into the channel memory (
page 30). If you are still
unable to tune digital channels, use the Reset Factory
Defaults procedure (
page 33). Also see “TV stops
responding to controls” and “Other problems”
(
page 53).
Closed caption problems
If the program or video you selected is not closed-
captioned, no captions will display (
page 42).
If text is not available, a black rectangle may appear. If
this happens, turn off the closed caption feature
(
page 42).
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 42).
Rating blocking (V-Chip) problems
If you forget your PIN code: While the PIN code
entering screen is displayed, press
four times
within 5 seconds. The PIN code you previously stored
will be cleared (
page 45).
HDMI problems
For HDMI cables
Make sure to use cables with the HDMI Logo
(

For Legacy HDMI source
Some legacy HDMI sources may not work properly
with the latest HDMI TV products, due to new standard
adoption.
