Appendix
Troubleshooting
Problem
Possible Solution
• No power.
•  Check if you pressed 
B on the remote control unit. (See page 8.)
  If the indicator on the TV lights up red, press 
B. 
•  Is the AC cord disconnected? (See page 4.)
•  Check if you pressed 
a on the TV. (See page 8.)
•  Unit cannot be operated.
•  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.
•  Remote control unit does not 
operate.
•  Are batteries inserted with polarity (
e, f) aligned? (See page 5.)
•  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? 
•  Picture is cut off.
•  Is the image position correct? (See page 18.)
•  Are screen mode adjustments (4:3 Mode/WSS) such as picture size made 
correctly? (See pages 18 and 20.)
•  Strange colour, light colour, or 
dark, or colour misalignment.
•  Adjust the picture tone. (See pages 13 and 14.)
•  Is the room too bright? The picture may look dark in a room that is too bright.
•  Check the colour system setting. (See pages 16 and 19.)
•  Check the HDMI Setup setting. (See page 19.)
•  Power is suddenly turned off.
•  The unit’s internal temperature has increased.
  Remove any objects blocking vent or clean.
•  Check the power control setting. (See page 15.)
•  Is sleep timer set? Press SLEEP on the remote control unit until it sets to Off.
•  No picture.
•  Is connection to other components correct? (See pages 9 and 10.)
•  Is input signal type selected correctly after connection? (See page 19.)
•  Is the correct input source selected? (See page 9.)
•  Is non-compatible signal being input? (See page 33.)
•  Is picture adjustment correct? (See pages 13 and 14.)
•  Is the antenna connected properly? (See page 4.)
•  Is “On” selected in “Audio Only”? (See page 18.)
•  No sound.
•  Is the volume too low? (See pages 6 and 7.)
•  Make sure that headphones are not connected. (See page 7.)
•  Check if you pressed 
e on the remote control unit. (See page 6.)
•  The DTV menu screen is displayed 
in monochrome and hard to select 
the item.
•  Check if “Monochrome” is set to “On”. If so, set it to “Off”. (See page 14.)
•  The TV sometimes makes a 
cracking sound.
•  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.
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: 
l20°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.
Repeat steps 1 to 3 in Changing the PIN. (See page 17.)
Enter “3001” to cancel out the current PIN.
•  The PIN resets to the factory preset “1234”.
