is set to ON.

 

When the monitor receives an input signal, it automatically 
matches the signal to one of the factory preset modes stored in the 
monitor’s memory to provide a high quality picture at the center 
of the screen. (See Appendix for a list of the factory preset 
modes.) For input signals that do not match one of the factory 
preset modes, the digital Multiscan technology of this monitor 
ensures that a clear picture appears on the screen for any timing in 
the monitor’s frequency range (horizontal: 30 – 130 kHz (CPD-
G520), 30 – 110 kHz (CPD-G420), vertical: 48 – 170 Hz). If the 
picture is adjusted, the adjustment data is stored as a user mode 
and automatically recalled whenever the same input signal is 
received.

 

For Windows users, check your graphics board manual or the 
utility program which comes with your graphics board and select 
the highest available refresh rate to maximize monitor 
performance.

 

This monitor meets the power-saving guidelines set by VESA,

The visible lines on your screen especially when the background 
screen color is light (usually white), are normal for the Trinitron 
monitor. This is not a malfunction. These are shadows from the 
damper wires used to stabilize the aperture grille. The aperture 
grille is the essential element that makes a Trinitron picture tube 
unique by allowing more light to reach the screen, resulting in a 
brighter, more detailed picture.

 

If there is something wrong with the input signal, one of the 
following messages appears on the screen.

 

1

 

This indicates that no signal is input from the selected connector.

If the problem is caused by the connected computer or other equipment, please refer to the connected equipment’s instruction manual.
Use the self-diagnosis function (page 22) if the following recommendations do not resolve the problem.

 

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.

If the NO SIGNAL message appears 
on the screen, or if the 

 

!

 

 (power) indicator is orange

• Check that the video signal cable is properly connected and all plugs are firmly seated in 

their sockets (page 6).

• Check that the INPUT switch setting is correct (page 9).
• Check that the video input connector’s pins are not bent or pushed in.

 

x

 

• The computer is in power saving mode. Try pressing any key on the keyboard or moving 

the mouse.

• Check that the computer’s power is “on.”
• Check that the graphic board is completely seated in the proper bus slot.

If the OUT OF SCAN RANGE 
message appears on the screen

 

x

 

• Check that the video frequency range is within that specified for the monitor. If you 

replaced an old monitor with this monitor, reconnect the old monitor and adjust the 
frequency range to the following.
Horizontal: 30 – 130 kHz (CPD-G520), 30 – 110 kHz (CPD-G420)
Vertical: 48 – 170 Hz

If no message is displayed and the 

 

!

 

 (power) indicator is green or 

flashing orange

• Use the Self-diagnosis function (page 22).

If using a Macintosh system

• When connecting to a Power Mac G3/G4 that has 3 rows of pins, check that the supplied 

exclusive Power Mac G3/G4 adapter and the video signal cable are properly connected 
(page 6).

• If you connect to the other version of Macintosh series computer that has 2 rows of pins, 

you will need a different adapter (not supplied).

 

• Isolate and eliminate any potential sources of electric or magnetic fields such as other 

monitors, laser printers, fluorescent lighting, televisions, or electric fans.

• 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.

 

x

 

• Check your graphics board manual for the proper monitor setting.
• Confirm that the graphics mode (VESA, Macintosh 21" Color, etc.) and the frequency of 

the input signal are supported by this monitor (Appendix). Even if the frequency is within 
the proper range, some graphics boards 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.

 

• Adjust the contrast and brightness (page 12).
• Degauss the monitor* (page 14).
• Adjust the degree of moire cancellation until the moire is minimal, or set CANCEL 

MOIRE to OFF (page 14).

 

21

 

* 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.

 

• Eliminate the use of video cable extensions and/or video switch boxes.
• Check that all plugs are firmly seated in their sockets.

 

• Set the AUTO (

) function to OK (on) in the SIZE/CENTER menu (page 13).

boards the periphery of the screen is not fully utilized.

 

• Adjust the geometry (page 13).

 

• Adjust the degree of moire cancellation until the moire is minimal (page 14).

 

x

 

• Change your desktop pattern.

 

• Degauss the monitor* (page 14). 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 (page 14) (CPD-G520 only).

 

• Adjust the color temperature (page 15).
• Check that the 5 BNC connectors are connected in the correct order (page 6).

 

• Adjust the convergence (page 14).

 

• If the control lock is set to ON, set it to OFF (page 17).

 

• Before using this function, the monitor must be in normal operation mode (green power 

indicator on) for at least 30 minutes. For more information on using the IMAGE 
RESTORATION function, see page 17.

• Adjust the computer’s power saving settings to keep the monitor in normal operation 

mode for more than 30 minutes.

• The monitor may gradually lose its ability to perform this function due to the natural aging 

of the picture tube.

 

• Check that the appropriate USB connectors are securely connected (page 8).
• Check that the 

 

!

 

 (power) switch is in the “on” position. Then reconnect the USB cable to 

the monitor. 

 

x

 

• Check that the power of any self-powered USB compliant peripheral devices is “on.”
• Install the latest version of the device driver on your computer. Contact your device’s 

manufacturer for information about the appropriate device driver.

• If your USB compliant keyboard or mouse does not function, connect them directly to 

your computer, reboot your computer, and make any necessary adjustments to the USB 
settings. Then reconnect the keyboard or mouse to the monitor. If you connect a keyboard 
or mouse to the USB connectors and then boot your computer for the first time, the 
peripheral devices may not function.

 

• This is the sound of the auto-degauss cycle. When the power is turned on, the monitor is 

automatically degaussed for a few seconds.
