the AC cord and replugging it in after 1 or 2 minutes.
• Is the FUNCTION set correctly? Set it to the TV setting position.
• Are batteries inserted with polarity ( e, f) aligned? (See page 7.)

• Are you using it under strong or fl uorescent lighting?
• Is a fl uorescent light illuminated near the remote control sensor?
• Is the image position correct? (See page 23.)
• Are screen mode adjustments such as picture size made correctly? (See page 16.)
• Adjust the picture tone. (See pages 19 and 20.)
• Is the room too bright? The picture may look dark in a room that is too bright.
• Check the input signal setting. (See page 22.)
• Is the sleep timer set? (See page 13.)
• Check the power control settings. (See page 21.)

This is not a malfunction, and the unit will recover when the temperature returns to normal.
• Do not leave the unit in a hot or cold location. Also, do not leave the unit in a location exposed to direct sunlight or near a
heater, as this may cause the cabinet to deform and the Liquid Crystal panel to malfunction.

• Check the antenna cable. Check that the antenna is correctly
setup.

contracts according to change in temperature. This does not affect the TV's
performance.
• The TV sometimes makes a
cracking sound.
