Troubleshooting
The Problems described below are not always caused by malfunctions. Check the monitor again before
having the monitor serviced.
Problems Solution
There is no picture or sound. • Is the power cord disconnected? (See page 20.)
• Has the power been turned on? (See page 22.)
• Check if you pressed ON on the remote control. (See page 22.)
If the POWER indicator on the monitor lights up green, press ON
on the remote control.
• Power to the external connected devices is off.
• Is the connection to external equipment correct? (See page 15.)
• Is the correct input mode selected? (See page 23.)
• Has the input signal setup been performed correctly after
connection? (See page 15.)
Remote control does not operate. • Are batteries inserted with polarity (+,-) aligned? (See page 21.)
• Are batteries worn out? Replace with new batteries. (See page 21.)
• Are you using it under strong or fl uorescent lighting?
• Is a fl uorescent light shining on the remote control sensor?
There is a picture but no sound. • Is the sound muted? (See page 23.)
• Make sure the volume is not set to minimum. (See page 23.)
• Are audio cables and speaker cables connected properly? (See
pages 17 and 18.)
• Is the audio signal input properly to the selected audio input
terminal? (See page 17.)
• Is “FAO” selected for “Audio Output” in the “Option” menu? (See
page 38.)
Picture is cut off.
Black bands appear at the edges
of the screen.
• Is the image position correct? (See page 35.)
• Are screen mode adjustments such as picture size made correctly?
(See page 24.)
Strange color, light color, or color
misalignment.
• Check the color adjustments and tint settings. (See page 30.)
• Check the signal type setting. (See page 39.)
Unstable picture. • Is a non-compatible signal being input? (See page 46.)
• Try the AUTO SYNC button on the remote control. (See page 26.)
TIMER indicator fl ashes red.
Power is suddenly turned off.
• The unit’s internal temperature has increased.
• Check whether the monitor is placed at a location where a quick
rise in temperature is likely. Internal temperature rises quickly if the
vents on the monitor are blocked.
• Internal temperature rises quickly if dust accumulates inside the
monitor or around the vents. Remove dust if possible. Consult an
EIKI Authorized Dealer about removing internal dust.
Power and picture change
automatically.
• Is “Sleep Timer” and/or “Schedule” set? (See page 41.)
• Check the power control setting. (See pages 32 and 33.)
The unit’s plastic parts make a
cracking noise.
• When the ambient temperature changes, the unit’s plastic parts will
slightly expand or shrink. This will cause a cracking noise. This is
not a fault, it will not affect the unit’s performance.
Cautions regarding use in high and low temperature environments
• When the unit 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 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: -4°F to +140°F (-20°C to +60°C).
This unit is equipped with a microprocessor. Its performance could be adversely affected by incorrect
operation or interference. If this should happen, unplug the unit and plug it in again after more than 5
minutes.
