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.

turned off.

stable or no Sound/
Picture colour noise

• 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.

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.
• Is battery inserted with polarity ( e , f ) aligned? (See page 6.)
• Is battery 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?
• Is the image position correct? (See page 16.)
• Are screen mode adjustments such as picture size made correctly? (See pages 15, 16 and
22.)
• Adjust the picture tone. (See page 12.)
• Is the room too bright? The picture may look dark in a room that is too bright.
• Check the colour system setting. (See pages 10 and 16.)
• Check the input signal setting. (See page 16.)
• Check the HDMI auto view setting. (See page 14.)
• The unit's internal temperature has increased.
Remove any objects blocking the vent or clean.
• Check the ECO setting. (See page 13.)
• Is the sleep timer set? (See page 6.)
• Switch to an appropriate Sound/Colour system setting may improve the Sound/Picture
quality. (See pages 10 and 16.)
• Is the connection to external equipment correct? (See page 5.)
• Has the input signal setup been performed correctly after connection? (See page 16.)

• Is "On" selected in "Audio only"? (See page 16.)

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