Channel tuning problems
Make sure the remote control is set to the correct device 
mode (
 page 22).
The channel may have been erased from the channel  
memory by the Channel Add/Delete feature. Add the 
channel to the channel memory (
 page 31).
The channel may be blocked by the Channels Block 
feature. Unblock the channel (
 page 48).
If you are unable to tune digital channels, check the 
antenna configuration (
 page 30). If you are still 
unable to tune digital channels, clear all channels from 
the channel list (
 page 32) and reprogram channels 
into the channel memory (
 page 31). If you are still 
unable to tune digital channels, use the Reset Factory 
Defaults procedure (
 page 34). Also see “TV stops 
responding to controls” and “Other problems” 
(
 page 55).
Closed caption problems
If the program or video you selected is not closed-
captioned, no captions will display (
 page 43).
If text is not available, a black rectangle may appear. If 
this happens, turn off the closed caption feature 
(
 page 43).
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 43).
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 46).
No HDMI Control operation
The HDMI Control feature is available for Toshiba 
HDMI Control compatible devices.
Make sure the HDMI cables with the HDMI Logo 
(
) are used.
When the connected HDMI Control device does not 
work correctly after you have changed settings of the 
device, turn off your TV and unplug the power cord, 
then plug and turn on again.
If several devices are connected, HDMI Control feature 
may not operate properly.
Read the instruction manual furnished with the 
connected HDMI Control device.
