• 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)

• Make sure that headphones are not connected.

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: e5°C to e35°C.
