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 14.) If the
indicator on the TV does not light up, press POWER on the TV.
• Is the AC cord disconnected? (See page 7.)
• Has the power been turned on? (See page 14.)
• 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 8.)
• 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 25.)
• Are screen mode adjustments such as picture size made correctly? (See page 18.)
• Adjust the picture tone. (See pages 21 and 22.)
• Is the room too bright? The picture may look dark in a room that is too bright.
• Check the input signal setting. (See page 24.)
• Is the sleep timer set? (See page 15.)
• Check the power control settings. (See page 23.)
• The unit's internal temperature has increased. Remove any objects blocking vent or
clean.
• Is connection to other components correct? (See pages 12 and 13.)
• Is correct input signal source selected after connection? (See page 28.)
• Is the correct input selected? (See page 28.)
• Is picture adjustment correct? (See pages 21 and 22.)
• Is "On" selected in "Audio Only"? (See page 28.)
• Is a non-compatible signal being input? (See page 42.)
• Is the volume too low? (See page 15.)
• Is "Variable" selected in "Output Select"? (See page 29.)
• Have you pressed MUTE on the remote control unit? (See page 15.)
• 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.
