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 noise.
• Cannot select the desired channel. • Switch between Digital TV and Analogue TV modes. (See page 9.)
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 e 60°C.
• Is the AC cord disconnected? (See page 10.)
• Has the power been turned on? (See page 13.)
• Check if you pressed POWER on the TV.
If the indicator on the TV lights up red, please press POWER on the remote control unit.
• External influences such as lightning, static electricity, etc., may cause improper
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.
• 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 fluorescent lighting?
• Is a fluorescent light shining on the remote control sensor?
• Is the image position correct? (See page 18.)
• Are screen mode adjustments such as picture size made correctly? (See pages 17
and 18.)
• Adjust the picture tone. (See pages 17.)
• Is the room too bright? The picture may look dark in a room that is too bright.
• Check the colour system setting. (See pages 15.)
• The unit's internal temperature has increased.
Remove any objects blocking the vent or clean.
• Is the sleep timer, no signal off set? (See pages 19 and 23.)
• Is the connection to external equipment correct? (See pages 11 and 24.)
• Is the correct input selected? (See pages 9,11 and 24.)
• Is the picture adjustment correct? (See pages 17 and 18.)
• Is the antenna connected properly? (See page 10.)
• Check the colour system setting. (See pages 15.)
• Is the volume too low? (See page 13.)
• Check the sound system setting. (See page 15.)
• Is Mute work? (See page 23.)
• 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.
