• External infl uences such as lightning, static electricity, etc., may cause improper

unplugging the AC cord and re-plugging it in after 1 or 2 minutes.
• Remote control unit does not
operate.
• Are batteries inserted with polarity (
e
,
f
) aligned? (See page 14.)
• Are batteries worn out? (Replace with new batteries.)
• Are you using it under strong or fl uorescent lighting?
• Is a fl uorescent light shining on the remote control sensor?
• Picture is cut off.
• Is the image position correct? (See page 32.)
• Are screen mode adjustments such as picture size made correctly? (See pages 27,
45 and 52.)
• Strange colour, light colour, dark,
or colour misalignment.
• Adjust the picture tone. (See pages 30 to 32.)
• Is the room too bright? The picture may look dark in a room that is too bright.
• Check the colour system setting. (See pages 19 and 42.)
• Check the “HDMI auto view” setting. (See page 40.)
• Power is suddenly turned off.
• The unit's internal temperature has increased.
Remove any objects blocking the vent or clean.
• Check the “ECO” setting. (See pages 26 and 27.)
• Is the sleep timer set? (See page 26.)
• No picture.

cracking noise.
• This is not a malfunction. This happens when the cabinet slightly expands and

performance.
Appendix
Cautions regarding use in high and low temperature environments
• When the unit is used in a low temperature space (e.g. room, offi ce), the picture may leave trails or appear slightly delayed.
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 LCD panel to malfunction.
