• Check that the TV is turned to the correct device or antenna
for that channel by pressing the INPUT button.
• Make sure the Parental Lock is off.
• If you cannot tune to a virtual digital channel even though the
TV has already memorized digital channels, tune to the actual

Only memorized analog channels can be named.
Available information is sent from the broadcaster or cable pro-
vider. No other data is available.
