Troubleshooting
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 Liquid Crystal panel to malfunction.
Storage temperature: –4°F to +140°F (–20°C to +60°C)
Troubleshooting-PC mode
Problem Possible Solution
• No power • Check if you pressed POWER on the remote control unit. (See page 17.) If the
indicator on the TV/DVD does not light up, press POWER on the TV/DVD.
• Is the AC cord disconnected? (See page 8.)
• Has the power been turned on? (See page 17.)
• Unit cannot be operated. • External influences such as lightning, static electricity, may cause improper
operation. In this case, operate the unit after first turning on the power of the TV/
DVD or unplugging the AC cord and replugging it in after 1 or 2 minutes.
• Remote control unit does not
operate.
• Are batteries inserted with polarity ( +, – ) aligned? (See page 9.)
• Are batteries worn out? (Replace with new batteries.)
• Are you using it under strong or fluorescent lighting?
• Is a fluorescent light illuminated near the remote control sensor?
• Picture is cut off/with sidebar
screen.
• Are screen mode adjustments such as view mode choose made correctly? (See
page 25.)
• Strange color, light color, or color
misalignment
• Adjust the picture tone. (See page 22.)
• Is the room too bright? The picture may look dark in a room that is too bright.
• Power is suddenly turned off. • Is the sleep timer set? (See page 12.)
• Check the power control settings. (See page 17.)
• The unit’s internal temperature has increased.
Remove any objects blocking vent or clean.
• No picture • Is connection to other components correct? (See pages 15 to 16.)
• Is correct input signal source selected after connection? (See page 16.)
• Is the correct input selected? (See page 16.)
• Is picture adjustment correct? (See page 22.)
• No sound • Is the volume too low? (See page 12.)
• Have you pressed MUTE on the remote control unit? (See page 12.)
• 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.
Problem Possible Solution
• There is no image. • Make sure the RGB cable is properly connected. (See page 34.)
• Make sure the output signal of the PC and the input signal setting of the LCD TV set
are matched.(See page 35.)
• Some software prohibit video playback on an external display when playing back a
video with a notebook PC. This is not attributable to a problem with the LCD TV set.
• There is no sound. • Make sure the PC audio cable is properly connected. (See page 34.)
• Check if the mute function activates, or if the volume is set to minimum. (See page
12.)
• The text is blurred. • Adjust “CLOCK” and “PHASE” using the PICTURE menu. (See page 35.)
• The image is not displayed in the
center of the screen.
