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 20.
• The tuner mode (in the Auto Tuner Setup) could be set improperly, refer to page 13.
• 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 (RM-C754 and RM-C751) — 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 17.
• 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 17.
• The power was interrupted or the power cord unplugged. Reset the clock, check page 16.
• The Sleep Timer may be set. 

• The power was interrupted and the clock not reset. Reset the clock, check page 16.

• There is a problem with the TV. Unplug the set and call for service.

CHECK

• Tint and color may be improperly adjusted. Check page 14.
• Video Status mode may be set to an inappropriate setting. Check page 14.

• 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,

page 6. If it is damaged, you will have to replace it.

• Closed Caption Text Mode is on. Press the C

button until you select Off.

CHECK

• Make sure the MTS mode is properly set. Refer to page 15 for details on setting MTS Modes.

• TV Speakers may be turned off in the menu, see page 16.

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.
