Installation

• Prevent internal heat build up by allowing adequate air

circulation. Do not place the monitor on surfaces (rugs, blankets, etc.) or near materials (curtains, draperies) that may block the ventilation holes.

• Do not install the monitor near heat sources such as

radiators or air ducts, or in a place subject to direct sunlight, excessive dust, mechanical vibration or shock.

• Do not place the monitor near equipment that generates

magnetism, such as a converter, or high voltage power lines.

Maintenance

• Clean the cabinet, panel and controls with a soft cloth

lightly moistened with a mild detergent solution. Do not use any type of abrasive pad, scouring powder or solvent such as alcohol or benzine.

• Do not rub, touch or tap the surface of the screen with

sharp or abrasive items such as a ball point pen or screwdriver. This type of contact may scratch the picture tube.

• Clean the screen with a soft cloth. If you use a glass cleaning liquid, do not use any type of cleaner containing an anti-static solution or similar additive as this may scratch the screen’s coating.

Transportation

• When you transport this monitor for repair or shipment, use the original carton and packing material.

Warning on Power Connection

• Use an appropriate power cord for your local power

supply.

for 220 to 240 V ACfor 100 to 120 V AC

• Before disconnecting the power cord, wait for at least 30

seconds after turning off the power to allow the static electricity on the CRT display surface to discharge.

• After the power has been turned on, the CRT is

demagnetized (degaussed) for about 5 seconds. This generates a strong magnetic field around the metal frame, which may affect the data stored on magnetic tapes and disks near the monitor. Place magnetic recording equipment, tapes and disks away from this monitor.

Precautions

Examples of plug types:

for 240 V AC only

The socket should be installed near the equipment and be easily accessible.

Plug and Play

This monitor complies with the DDC

1 and DDC2B Display Data Channel (DDC) standards of VESA. When a DDC1 host system is connected, the monitor synchronizes with the V. CLK in accordance with the VESA standards, and outputs the EDID (Extended Display Identification Data) to the data line. When a DDC2B host system is connected, the monitor automatically switches to the appropriate standard.

DDC

is a trademark of Video Electronics Standard

Association.

• Your monitor operates according to DDC2B. Only

computers that support the same guidelines and operate at the same or higher level can make use of this feature.

• If your computer does not support the relevant

guidelines, you can still use your monitor and computer. You may need to manually specify the appropriate resolution in the computer.

• The highest resolution automatically selected may not

give the best result. You may need to manually select the most suitable resolution in the computer.

Damper wires

When viewing a white background, two very thin horizontal lines may be visible on the screen as shown below. These lines are the damper wires. The Trinitron tube has a vertically striped aperture grille inside. The aperture grille allows more light to pass through to the screen giving the Trinitron CRT more color and brightness. These damper wires are attached to the aperture grille to prevent vibration of the aperture grille and keep the screen image constantly stable.

Power Saving Function and LED Indicator

This monitor has three Power Saving modes. By sensing the absence of a video signal from the computer, it reduces power consumption as follows.

should appear with a color bar pattern. The message and pattern are displayed for 30

seconds. If the monitor displays White, Red, Green and Blue colors, the monitor is functioning properly.

• Make sure none of the HD15 video input connector pins are bent or pushed in.

• Check your video board manual for the proper monitor setting.

• Check this manual and make sure the monitor supports the graphics mode and the frequency at which you are trying to operate. Even if the frequency is within the proper range, some video boards may have a sync pulse that is too narrow for the monitor to sync correctly.

• Degauss the monitor (page 8). If you place equipment which generates a magnetic field, such as a loudspeaker, near the monitor, or you change the direction of the monitor, the color may not be uniform. The degauss function demagnetizes the metal frame of the CRT to obtain a neutral field for uniform color reproduction. If a second degauss cycle is needed, allow a minimum interval of 20 minutes for the best result.

The input signal condition

“OUT OF SCAN RANGE” indicates that the input signal is not supported by the monitor’s specifications.

“NO INPUT SIGNAL” indicates that no signal is input. The message disappears after about 30 seconds.

To solve these problems, see the “Troubleshooting” section below.

Symptom Check these items

You cannot adjust the monitor with the buttons on the front panel

Screen image is not centered or sized properly

Edges of the image are curved White lines show red or blue

shadows at edges Picture is fuzzy

Picture bounces or has wavy oscillations

Picture is flickering

Picture appears to be ghosting

Wavy or elliptical (moire) pattern is visible

Two fine horizontal lines (wires) are visible

Hum is heard right after the power is turned on

White does not look white

• If the Control Lock function is set to “ON,” set it to “OFF” using the OPTION OSD (page 8).

• Adjust the size (page 8) or centering (page 7).

• Some video modes do not fill the screen to the edges. This problem tends to occur with certain video boards.

• Adjust the geometry (page 9).

• Adjust the convergence using the SCREEN OSD (page 7).

• Adjust the contrast and brightness (page 5).

• Degauss the monitor using the OPTION OSD (page 8). If you place equipment which generates a magnetic field, such as a loudspeaker, near the monitor, or you change the direction of the monitor, the color may not be uniform. The degauss function demagnetizes the metal frame of the CRT to obtain a neutral field for uniform color reproduction. If a second degauss cycle is needed, allow a minimum interval of 20 minutes for the best result.

• If red or blue shadows appear along the edges of images, adjust the convergence using the SCREEN OSD (page 7).

• If the moire is cancelled, the picture may become fuzzy. Decrease the moire cancellation effect using the SCREEN OSD (page 7).

• Isolate and eliminate any potential sources of electric or magnetic fields. Common causes for this symptom are electric fans, fluorescent lighting and laser printers.

• If you have another monitor close to this monitor, increase the distance between them to reduce the interference.

• Try plugging the monitor into a different AC outlet, preferably on a different circuit.

• Try using the monitor with a different computer in a different room.

• Refer to your computer system’s manual and change your display refresh rate settings so they match the monitor’s capabilities.

• Eliminate the use of video cable extensions and/or video switch boxes. Excessive cable length or a weak connection can produce this symptom.

• Cancel the moire using the SCREEN OSD (page 7). The moire may be modified depending on the connected computer.

• Due to the relationship between resolution, monitor dot pitch and the pitch of some image patterns, certain screen backgrounds sometimes show moire. Change your desktop pattern.

• These wires stabilize the vertically striped aperture grille (page 11). This aperture grille allows more light to pass through to the screen giving the Trinitron CRT more color and brightness.

• When the power is turned on, the auto-degauss cycle is activated. While the auto-degauss cycle is activated, a hum may be heard. The same hum is heard when the monitor is manually degaussed. This is not a malfunction.

• Adjust the color temperature using the COLOR OSD (page 7).

• REMOVAL OF ANODE-CAP

NOTE: Short circuit the anode of the picture tube and the anode cap to the metal chassis, CRT shield or carbon painted on the CRT, after

removing the anode.

• REMOVING PROCEDURES

Anode Button

1 Turn up one side of the rubber cap in

the direction indicated by the arrow a.

2 Using a thumb pull up the rubber cap

firmly in the direction indicated by the arrow b.

• HOW TO HANDLE AN ANODE-CAP

1 Don’t hurt the surface of anode-caps with shartp shaped

material!

2 Don’t press the rubber hardly not to hurt inside of anode-caps!

A material fitting called as shatter-hook terminal is built in the rubber.

3 Don’t turn the foot of rubber over hardly!

The shatter-hook terminal will stick out or hurt the rubber.

3 When one side of the rubber cap is

separated from the anode button, the anode-cap can be removed by turning up the rubber cap and pulling up it in the direction of the arrow c.
