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)

indicator on the TV does not light up, press POWER on the TV.
• Is the AC cord disconnected? (See page 7.)
• Has the power been turned on? (See page 16.)
• 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 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 8.)
• 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 21.)
• 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 11.)
• Check the power control settings. (See page 16.)

performance.
