Appendix
Troubleshooting
Problem Possible Solution
• No power. •  Check if you pressed B on the remote control unit.
    If the indicator on the TV lights up red, press  B. 
•  Is the AC cord disconnected?
•  Check if you pressed  a on the TV.
•  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?
•  Are batteries worn out? (Replace with new batteries.)
•  Are you using it under strong or fluorescent lighting?
•  Is a fluorescent light illuminated onto the remote control sensor? 
•  Picture is cut off. •  Is the image position correct? •  Are screen mode adjustments (WIDE MODE) such as picture size made correctly? (Pages 29 and 33)
•  Strange colour, light colour, or  dark, or colour misalignment. •  Adjust the picture tone.
•  Is the room too bright? The picture may look dark in a room that is too bright.
•  Check the colour system setting. (Pages 27 and 32)
•  Power is suddenly turned off. •  The unit’s internal temperature has increased.     Remove any objects blocking the vent or clean.
•  Is the sleep timer set? Select “Off” from the “Sleep Timer” menu. (Page 26)
•  Is “No signal off” activated?
•  No picture. •  Are connections to external equipment correct? (Pages 15-17) •  Is the input signal type selected correctly after connection? (Page 32)
•  Is the correct input source selected? (Page 10)
•  Is a non-compatible signal being input? (Page 36)
•  Is the picture adjustment correct? (Pages 24-25)
•  Is the antenna connected properly? (Page 8)
•  Is “On” selected in “Audio Only”? (Page 30)
•  No sound. •  Is the volume too low? •  Make sure that headphones are not connected.
•  Check if you pressed e on the remote control unit.
•  The TV sometimes makes a  cracking sound. •  This is not a malfunction. This happens when the cabinet slightly expand\
s and 
contracts according to change in temperature. This does not affect the TV’s 
performance.
