• Check to see that the batteries are still working and properly installed.
• Make sure the remote has a clear sight path to the TV.
• Check that the TV/CATV switch is in the proper position.
• You may be too far from the TV. You must be within 23 feet (7 meters).
• Make sure the channels have been programmed. See "Channel Summary", page 24.
• Check to see if the channel is locked. See "Channel Summary - Lock" page 25.

• There could be interference from another electrical appliance, such as a computer,
another TV or VCR. Move any such appliances further away from the TV.
• There could be interference from a high-wattage appliance, like a hairdryer or vacuum,
operating nearby. Move the antenna away from the appliance or change to a coaxial
cable connection which is less prone to interference.
• A building or passing airplane can reflect the original signal and produce a second,
slightly delayed one. Adjust your antenna position.
• Your antenna may be damaged, disconnected or turned. Check the antenna
connection. If the antenna is damaged, replace it.
• The Closed Caption Text mode is on. Turn it off in the Closed Caption Menu, page 32.

"V2-COMPONENT" by pressing the INPUT button. See page 13 and 42.

"VIDEO-2" by pressing the INPUT button. See page 13 and 42.
The O mark will appear if you press the ASPECT button under these conditions:
• While noise muting is on over channels which are not broadcasting or are too weak to
be received.
• When a channel is locked by CHANNEL GUARD.
• It is normal to feel static electricity if you brush or touch the screen.
• It is normal for the TV to make crackling sounds when first turned on or off. Unless
the sound or picture become abnormal, this is fine.
