Troubleshooting
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, 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: –20°C to e60°C.
IMPORTANT NOTE ON RESETTING THE PIN
We suggest that you remove the following instruction from the operation manual to prevent children from
reading it. As this operation manual is multilingual, we also suggest the same with each language. Keep it in
a safe space for future reference.
1
Repeat steps 1 to 3 in Changing the PIN. (See page 16.)
2
Enter "3001" to cancel out the current PIN.
• Check if you pressed B on the remote control unit. (See page 7.)
If the indicator on the TV lights up red, press B.
• Is the AC cord disconnected? (See page 3.)
• Check if you pressed a on the TV. (See page 7.)
• External influences such as lightning, static electricity, etc., may cause improper
operation. In this case, operate the unit after first turning the power off, 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 4.)
• Are batteries worn out? (Replace with new batteries.)
• Are you using it under strong or fluorescent lighting?
• Is a fluorescent light illuminated to remote control sensor?
• Is the image position correct? (See page 16.)
• Are screen mode adjustments (4:3 Mode/WSS) such as picture size made
correctly? (See pages 17 and 19.)
• Adjust the picture tone. (See pages 12 and 13.)
• 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 and 18.)
• The unit's internal temperature has increased.
Remove any objects blocking vent or clean.
• Check the power control setting. (See page 14.)
• Is sleep timer set? Press SLEEP on the remote control unit until it sets to Off.
• Is connection to other components correct? (See pages 8 and 9.)
• Is input signal type selected correctly after connection? (See page 18.)
• Is the correct input source selected? (See page 8.)
• Is non-compatible signal being input? (See page 23.)
• Is picture adjustment correct? (See pages 12 and 13.)
• Is the antenna connected properly? (See page 3.)
• Is "On" selected in "Audio Only"? (See page 18.)
• Is the volume too low? (See pages 5 and 6.)
• Make sure that headphones are not connected. (See page 6.)
• Check if you pressed e on the remote control unit. (See page 5.)
• This is not a malfunction. This happens when the cabinet slightly expands and
contracts according to change in temperature. This does not affect the TV's
performance.
