Troubleshooting
x No picture
If the ! (power) indicator is not lit
• Check that the power cord is properly connected.
• Check that the ! (power) switch is in the “on” position.
The ! (power) indicator is orange
• Check that the video signal cable is properly connected and all plugs
are firmly seated in their sockets.
• Check that the INPUT switch setting is correct.
• Check that the HD15 video input connector’s pins are not bent or
pushed in.
• Check that the computer’s power is “on”.
• The computer is in power saving mode. Try pressing any key on the
computer keyboard or moving the mouse.
• Check that the graphic board is completely seated in the proper bus
slot.
If the ! (power) indicator is green or flashing orange
• Use the Self-diagnosis function.
x Picture flickers, bounces, oscillates, or is scrambled
• Isolate and eliminate any potential sources of electric or magnetic
fields such as other monitors, laser printers, electric fans, fluorescent
lighting, or televisions.
• Move the monitor away from power lines or place a magnetic shield
near the monitor.
• Try plugging the monitor into a different AC outlet, preferably on a
different circuit.
• Try turning the monitor 90° to the left or right.
• Check your graphics board manual for the proper monitor setting.
• Confirm that the graphics mode and the frequency of the input signal
are supported by this monitor (see “Preset mode timing table” on
page i). Even if the frequency is within the proper range, some
graphics board may have a sync pulse that is too narrow for the
monitor to sync correctly.
• Adjust the computer’s refresh rate (vertical frequency) to obtain the
best possible picture.
x Picture is fuzzy
• Adjust the contrast, brightness, and PICTURE EFFECT.
• Degauss the monitor.*
• Adjust the degree of moire cancellation until the moire is minimal,
or set CANCEL MOIRE to OFF.
x Picture is ghosting
• Eliminate the use of video cable extensions and/or video switch
boxes.
• Check that all plugs are firmly seated in their sockets.
x Picture is not centered or sized properly
• Perform the Auto Size Center function.
• Adjust the size or centering. Note that with some input signals and/
or graphics board the periphery of the screen is not fully utilized.
• Just after turning on the power switch, the size/center may take a
while to adjust properly.
x Edges of the image are curved
• Adjust the geometry.
x Wavy or elliptical pattern (moire) is visible
• Adjust the degree of moire cancellation until the moire is minimal.
• Change your desktop pattern.
x Color is not uniform
• Degauss the monitor.* If you place equipment that generates a
magnetic field, such as a speaker, near the monitor, or if you change
the direction the monitor faces, color may lose uniformity.
• Adjust the landing.
x White does not look white
• Adjust the color temperature.
x Monitor buttons do not operate ( appears on the
screen)
• If the control lock is set to ON, set it to OFF.
x Letters and lines show red or blue shadows at the
edges
• Adjust the convergence.
x A hum is heard right after the power is turned on
• This is the sound of the auto-degauss cycle. When the power is
turned on, the monitor is automatically degaussed for a few seconds.
* If a second degauss cycle is needed, allow a minimum interval of
20 minutes for the best result. A humming noise may be heard, but this is
not a malfunction.
