CHECK
• See if the power cord became unplugged.
• Perhaps you have experienced a blown circuit breaker or fuse or a power outage.
• The antenna could be disconnected.
• The input mode (TV or Video) could not be set properly, refer to page 25.
• The tuner mode (in the Auto Tuner Setup) could be set improperly, refer to page 12.
• The station may be having difficulties, check to see if other channels are operating normally.
• Check that the batteries are still working and properly installed.
• Make sure there are no objects blocking a clear path from the remote to the TV.
•
Check that the TV/CAT V switch is in the proper position — set to TV to view television.
• Maybe you are too far from the TV, you must be within 23 feet (or 7 meters).
• Make sure the channels are programmed. See Channel Summary, page 12.
• Perhaps the channel is locked, select it with the 10 key pad and follow instructions on page 13.
• Perhaps the On/Off Timer is set, press the power button, check page 18.

CHECK
• Tint and color may be improperly adjusted. Check page 15.
• Video Status mode may be set to an inappropriate setting. Check page 24.
• There could be interference from another energy consuming appliance, such as a computer,
another TV or VCR. Move any other such appliances farther away from the TV.
• T h e re could be interf e rence from a running high wattage appliance such as a hair- d ry e r, vacuum
c l e a n e r, or neon sign. You will have to move the antenna away from the source of the
i n t e rf e rence or change it to a coaxial cable which is less prone to interf e re n c e .
• A building or airplane can reflect the original signal producing a second, delayed one. Adjust
the antenna position.
• The antenna may be damaged, disconnected or turned. Check the antenna connection,
page 6, and your Quick Setup Guide. If it is damaged, you will have to replace it.
• Closed Caption Text Mode is on. Turn it off in the Closed Caption Menu (page 18).

• Has the Muting button been pressed? If so, press Muting again to return volume to normal.
• Is an earphone/headphone attached to the jack at the front of the TV? If the phones jack is in

DON’T WORRY ABOUT THIS, IT’S NORMAL
• It is normal to feel a surge of static electricity if you brush over or touch the scre e n .
• It is normal for the TV to emit crackling sounds when turned on or off. Unless the sound or
picture become abnormal, this is fine.
