TV Channels
Symptom
1. The TV takes several seconds to respond to
channel changes.
2. You cannot access a channel.
Remarks
• It is normal for digital channels to take longer to tune in.
• Press ENTER after entering a channel number to minimize
delays.
• Use a 4-digit number for an over-the-air digital channel.
• Use a 6-digit number for digital cable channels if your cable
service is able to recognize 6-digit channel numbers.
• Use number keys instead of CH.
• Be sure the channel you want to view is in memory.
• Check that the TV is switched to the correct device or
antenna for that channel by pressing the INPUT key.
• Make sure the channel is not locked in the Locks menu.
• If you cannot tune to a virtual digital channel even though
the TV has already memorized digital channels, tune to the
physical channel number used by the broadcaster. The
virtual channel will then be automatically added to memory.
• You may be trying to tune to an analog channel that is no
longer broadcasting.
