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 Liquid Crystal panel to malfunction.

Storage temperature: f4°F to e140°F (f20°C to e60°C)

• Check if you pressed TV POWER on the remote control unit. (See page 12.) If the

indicator on the TV does not light up, press POWER on the TV.

• Is the AC cord disconnected? (See page 6.)

• Has the power been turned on? (See page 12.)

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

In this case, operate the unit after ﬁ rst turning off the power of the TV or unplugging

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 batteries worn out? (Replace with new batteries.)

• 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.)

• The unit's internal temperature has increased. Remove any objects blocking vent or

clean.

• Is connection to other components correct? (See page 11.)

• Is correct input signal source selected after connection? (See page 26.)

• Is the correct input selected? (See page 26.)

• Is picture adjustment correct? (See pages 19 and 20.)

• Is "On" selected in "Audio Only"? (See page 26.)

• Is a non-compatible signal being input? (See page 38.)

• Is the volume too low? (See page 13.)

• Is "Variable" selected in "Output Select"? (See page 26.)

• Have you pressed MUTE on the remote control unit? (See page 13.)

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

contracts according to change in temperature. This does not affect the TV's

performance.
