TV Channels

Symptom

Remarks

1.

The TV takes several seconds to respond to
channel changes.

• It is normal for digital channels to take longer to tune in.
• Press ENTER after a entering channel number to avoid 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.

2.

You cannot access a channel.

• Use number keys instead of CH / .
• Be sure the channel you want to view is in memory. See Setup >

Scan on page 42.

• Check that the TV is switched to the correct device or antenna for

that channel by pressing the INPUT key.

• Make sure Channel Lock is off.
• Make sure the Lock > Parent menu lock is set to off.
• 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.
