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)
• Check if you pressed
POWER on the remote control unit. (See page 17.)
If the indicator on the LCD Monitor does not light up, press POWER on the
LCD Monitor.
•
Is the AC cord disconnected? (See page 9.)
•
Has the main POWER been turned ON? (See page 9.)
•
Has the power been turned on? (See page 9.)
• External influences such as lightning, static electricity, may cause improper
operation. In this case, operate the unit after first turning off the power of
the LCD Monitor or unplugging the AC cord and replugging it in after 1 or 2
minutes.
• Are batteries inserted with polarity (+, –) aligned? (See page 10.)
•
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?
•
Is the image position correct? (See page 27.)
•
Are screen mode adjustments such as picture size made correctly? (See
page 20.)
•
Adjust the picture tone. (See pages 23 and 24.)
• Is the room too bright? The picture may look dark in a room that is too
bright.
• Check the input signal setting. (See page 26.)
•
Is the sleep timer set? (See page 19.)
• Check the power control settings. (See page 25.)
• The unit's internal temperature has increased. Remove any objects blocking
vent or clean.
•
Is connection to other components correct? (See pages 14 to 16.)
•
Is correct input signal source selected after connection? (See page 27.)
•
Is the correct input selected? (See page 27.)
•
Is picture adjustment correct? (See pages 23 and 24.)
•
Is "On" selected in "Audio Only"? (See page 27.)
•
Is a non-compatible signal being input? (See page 16.)
• Are the speakers connected correctly? (See page 8.)
•
Is the volume too low? (See page 18.)
• Is "Variable" selected in "Output Select"? (See page 28.)
•
Have you pressed MUTE on the remote control unit? (See page 18.)
• This is not a malfunction. This happens when the cabinet slightly expands
and contracts according to change in temperature. This does not affect the
LCD Monitor's performance.
