• Unit cannot be operated.
• Remote control unit does not
operate.
• Picture is cut off screen.
• Strange color, light color, or color
misalignment
• Power is suddenly turned off.
• No picture
• No sound
• Check if you pressed POWER on the remote control unit. (See page 13.) If the
indicator on the TV/DVD does not light up, press POWER on the TV/DVD.
• Is the AC cord disconnected? (See page 7.)
• Has the power been turned on? (See page 13.)
• External infl uences such as lightning, static electricity, may cause improper
operation. In this case, operate the unit after fi rst turning on the power of the
TV/DVD or unplugging the AC cord and replugging it in after 1 or 2 minutes.
• Are batteries inserted with polarity (+,
–
) aligned? (See page 8.)
• Are batteries worn out? (Replace with new batteries.)
• Are you using it under strong or fl uorescent lighting?
• Is a fl uorescent light illuminated near the remote control sensor?
• Are screen mode adjustments such as view mode choose made correctly? (See
page 22.)
• Adjust the picture tone. (See page 17.)
• Is the room too bright? The picture may look dark in a room that is too bright.
• Is the sleep timer set? (See page 11.)
• Check the power control settings. (See page 13.)
• The TV/DVD’s internal temperature has increased.
Remove any objects blocking vent or clean.
• Is connection to other components correct? (See pages 19 to 20.)
• Is correct input signal source selected after connection? (See page 19.)
• Is the correct input selected? (See page 19.)
• Is picture adjustment correct? (See page 17.)
• When the TV/DVD is used in a low temperature space (e.g. room, offi ce), the picture may leave trails or appear slightly
delayed. This is not a malfunction, and the TV/DVD will recover when the temperature returns to normal.
• Do not leave the TV/DVD in a hot or cold location. Also, do not leave the TV/DVD 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.
