Troubleshooting

x No picture

If the 1 (power) indicator is not lit

• Check that the power cord is properly connected.

• Check that the 1 (power) switch is in the “on” position.

The 1 (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 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 1 (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

• This monitor has a high luminance mode, so small characters may

not appear clearly if the monitor receives signals over 1280 × 1024

resolution. If this occurs, lower the contrast or set the computer to a

lower resolution.

• Adjust the brightness and contrast.

• Degauss the monitor.*

• Adjust for minimum moire.

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

• 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 for minimum moire.

• 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.

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 five 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.
