serviced.
Problem
Possible solution

on the TV after waiting more than five seconds.

operation. In this case, operate the unit after first turning the power off the TV or
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 fluorescent lighting?
• Is a fluorescent light shining on the remote control sensor?
• Picture is cut off.
• Is the image position correct? (See page 20.)
• Are screen mode adjustments such as picture size made correctly? (See pages 19
and 20.)
• Strange colour, light colour, or
dark, or colour misalignment.
• Adjust the picture tone. (See pages 19.)
• Is the room too bright? The picture may look dark in a room that is too bright.
• Check the colour system setting. (See pages 18 and 26.)
• Check the “HDMI auto view” setting. (See page 23.)
• Power is suddenly turned off.
• The unit's internal temperature has increased.
Remove any objects blocking the vent or clean.
• Is the sleep timer, no signal off or no operation off set? (See pages 21,22 and 28.)
• No picture.
• Is the connection to external equipment correct? (See pages 13 and 30.)

cracking noise.

performance.

Cautions regarding use in high and low temperature environments
• When the unit is used in a low temperature space (e.g. room, office), 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.
Storage temperature:
f
20°C to
