Troubleshooting

The problems described below are not always caused by malfunctions. Check the TV again before having the TV
serviced.
Problem
• No power.
• Unit cannot be operated.
• Remote control unit does not
operate.
• Picture is cut off.
• Strange colour, light colour, or
dark, or colour misalignment.
• Power is suddenly turned off.
• No picture.
• No sound.
• The TV sometimes makes a
cracking sound.
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.
Storage temperature: f 20°C to e 60°C.

• Check if you pressed POWER on the remote control unit. (See page 13.)
If the indicator on the TV lights up red, press POWER.
• Is the AC cord disconnected? (See page 9.)
• Has the power been turned on? (See page 13.)
• External infl uences such as lightning, static electricity, etc., may cause improper
operation. In this case, operate the unit after fi rst turning the power off the TV or
unplugging the AC cord and re-plugging it in after 1 or 2 minutes.
• Are batteries inserted with polarity ( e , f ) aligned? (See page 12.)
• 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?
• Is the image position correct? (See page 32.)
• Are screen mode adjustments such as picture size made correctly? (See pages 27,
28 and 38.)
• 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 36.)
• Check the input signal setting. (See page 40.)
• Check the HDMI Auto View setting. (See page 34.)
• The unit's internal temperature has increased.
Remove any objects blocking the vent or clean.
• Check the power control setting. (See pages 25 and 26.)
• Is the sleep timer set? (See page 25.)
• Is the connection to external equipment correct? (See pages 10, 11, 34, 37 and 38.)
• Has the input signal setup been performed correctly after connection? (See page
40.)
• Is the correct input selected? (See page 35.)
• Is the picture adjustment correct? (See pages 30 to 32.)
• Is the antenna connected properly? (See page 9.)
• Is "On" selected in "Audio Only"? (See page 22.)
• Is the volume too low? (See page 17.)
• Make sure that headphones are not connected. (See page 7.)
• This is not a malfunction. This happens when the cabinet slightly expands and
contracts according to changes in temperature. This does not affect the TV's
performance.
