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 8.)
If the indicator on the TV lights up red, press POWER.
• Is the AC cord disconnected?
• Has the power been turned on? (See page 8.)
• 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 6.)
• Are batteries worn out? (Replace with new battery.)
• Are you using it under strong or fl uorescent lighting?
• Is a fl uorescent light shining on the remote control sensor?
• Are screen mode adjustments such as picture size made correctly? (See pages 13 and 14.)
• Adjust the picture tone. (See page 10.)
• Is the room too bright? The picture may look dark in a room that is too bright.
• Check the colour system setting. (See page 9.)
• The unit's internal temperature has increased.
Remove any objects blocking the vent or clean.
• Is the sleep timer set? (See pages 6 and 11.)
• Is the connection to external equipment correct? (See pages 4 and 5.)
• Is the correct input selected?
• Is the picture adjustment correct? (See page 10.)
• Is the antenna connected properly? (See page 3.)
• Is the volume too low? (See page 6.)
• Make sure that headphones are not connected.
• 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.
