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.

and then press a (POWER) on the TV after waiting for more than fi ve seconds.
• Is the AC cord disconnected?
• Has the power been turned on? (See page 6.)
• 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 (+, –) aligned? (See page 5.)
• 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?
• Are screen mode adjustments such as picture size made correctly? (See page 10.)
• Adjust the picture tone. (See page 11.)
• Is the room too bright? The picture may look dark in a room that is too bright.
• Check the colour system setting. (See page 8.)
• The unit's internal temperature has increased.
• Remove any objects blocking the vent or clean.
• Check the Auto Sleep setting. (See page 12.)
• Is the sleep timer set? (See page 12.)
• Is the connection to external equipment correct? (See page 4.)
• Is the Picture Mode adjustment correct? (See page 11.)
• Is the antenna connected properly? (See page 3.)
• Is the volume too low? (See page 5.)
• 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.
