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: f 4°F to e 140°F ( f 20°C to e 60°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 16.)

• Has the power been turned on? (See page 18.)

• 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? *

• 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? *

• Are screen mode adjustments such as picture size made correctly? *

• Adjust the picture tone. *

• Is the room too bright? The picture may look dark in a room that is too bright.

• Check the input signal setting. *

• Is the sleep timer set? *

• Check the power control settings. *

• The unit's internal temperature has increased.

Remove any objects blocking vent or clean.

• Is connection to other components correct? *

• Is correct input signal source selected after connection? *

• Is the correct input selected? *

• Is picture adjustment correct? *

• Is "On" selected in "Audio Only"? *

• Is a non-compatible signal being input? *

• Is the volume too low? *

• Is "Variable" selected in "Output Select"? *

• Have you pressed MUTE on the remote control unit? *

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

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

performance.
