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 41.
• The tuner mode (in the menu selection) could be set improperly, refer to page 17.
• 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 2-way mode selector 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 34.
• Perhaps the channel is locked, select it with the 10 key pad and follow instructions.
• Perhaps the On/Off Timer is set, press the power button, check page 38.
• The power was interrupted or the power cord unplugged.
• The Sleep Timer may be set, see page 40.

CHECK
• Tint and color may be improperly adjusted. Check page 35.
• Video Status mode may be set to an inappropriate setting. Check page 35.
• 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 interf e r-
ence 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,
pages 7 to 8. If it is damaged, you will have to replace it.

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.
