LEAKAGE TEST

The AC leakage from any exposed metal part to earth ground

and from all exposed metal parts to any exposed metal part hav-

ing a return to chassis, must not exceed 0.5 mA (500 microam-

peres).

Leakage current can be measured by any one of three methods.

1. A commercial leakage tester, such as the Simpson 229 or

RCA WT-540A. Follow the manufacturers’ instructions to

use these instruments.

2. A battery-operated AC milliammeter. The Data Precision

245 digital multimeter is suitable for this job.

3. Measuring the voltage drop across a resistor by means of a

VOM or battery-operated AC voltmeter. The “limit” indica-

tion is 0.75 V, so analog meters must have an accurate low-

voltage scale. The Simpson 250 and Sanwa SH-63Trd are

examples of a passive VOMs that are suitable. Nearly all

battery operated digital multimeters that have a 2 V AC

range are suitable. (See Fig. A)

After correcting the original service problem, perform the fol-

lowing safety checks before releasing the set to the customer:

1. Check the area of your repair for unsoldered or poorly-sol-

dered connections. Check the entire board surface for solder

splashes and bridges.

2. Check the interboard wiring to ensure that no wires are

“pinched” or contact high-wattage resistors.

3. Check that all control knobs, shields, covers, ground straps,

and mounting hardware have been replaced. Be absolutely

certain that you have replaced all the insulators.

4. Look for unauthorized replacement parts, particularly tran-

sistors, that were installed during a previous repair. Point

them out to the customer and recommend their replacement.

5. Look for parts which, though functioning, show obvious

signs of deterioration. Point them out to the customer and

recommend their replacement.

6. Check the line cords for cracks and abrasion. Recommend

the replacement of any such line cord to the customer.

7. Check the B+ and HV to see if they are specified values.

Make sure your instruments are accurate; be suspicious of

your HV meter if sets always have low HV.

8. Check the antenna terminals, metal trim, “metallized”

knobs, screws, and all other exposed metal parts for AC

Leakage. Check leakage as described below.

SECTION 1

GENERAL

The operating instructions mentioned here are partial abstracts

from the Operating Instruction Manual. The page numbers of

the Operating Instruction Manual remain as in the manual.

1-1

Getting Started

Use of the Tilt-Swivel

This monitor can be adjusted within the angles shown

below. To find the center of the monitor’s turning radius,

align the center of the monitor’s screen with the centering

dots on the stand.

Hold the monitor at the bottom with both hands when you

turn it horizontally or vertically. Be careful not to pinch

your fingers at the back of the monitor when you tilt the

monitor up vertically.

Note

Do not remove the tilt-swivel base from the monitor.

Warning on power connection

• Use an appropriate power cord for your local power

supply.

Examples of plug types:

• Before disconnecting the power cord, wait 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 2 seconds. This

generates a strong magnetic field around the metal frame,

which may affect the data stored on magnetic tapes and

disks near the bezel. Place magnetic recording equipment,

tapes, and disks away from this monitor.

The equipment should be installed near an easily

accessible electrical outlet.

Precautions

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 which generates

magnetism, such as a transformer 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 ballpoint pen or

screwdriver. This type of contact may result in a scratched

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 materials.

Workplace Preparation

Positioning the Monitor

Choose a suitable place to position the monitor where it is

not near fluorescent desk lighting or any equipment that

produces magnetic fields that could cause interference.

Ensure that the furniture or equipment can support the

weight of the monitor. Allow at least 2 inches (50mm)

ventilation space around the monitor.

Height

The monitor should be positioned so that the top of the

screen is slightly below your eye level when you sit at your

workstation.

Orientation

Choose a position that gives the least reflection from lights

and windows, usually at a right angle to any windows. The

monitor should be positioned directly in front of you so that

you do not have to twist your body. Tilt the monitor to a

comfortable viewing angle.

Working Practices

Rest

Take regular breaks. Vary your posture, and stand up and

stretch occasionally as prolonged use of computer

workstations can be tiring.

Back

You should sit back in the chair and use the backrest.

Hands

Use a light touch on the keyboard, keeping your hands and

fingers relaxed. Allow a space in front of the keyboard to

rest your wrists when not typing. Consider using a

wristpad.

Eyesight

Working with monitors, in common with any kind of

prolonged close work, can be visually demanding. Look

away from the screen periodically and have your eyesight

checked regularly.

Screen settings

Set the screen brightness and contrast to a comfortable level.

You may have to adjust this as the lighting changes during

the day. Many application programs let you select color

combinations which can help you to view in comfort.

Selecting the Input Signal

You can connect two computers to this monitor using the

video input 1 (J1) and video input 2 (J2) connectors. To

select one of the two computers, use the input switch.

Move the input switch.

The selected connector appears on the screen for 3 seconds.

“INPUT 1” (video input 1 connector: J1) or “INPUT 2”

(video input 2 connector: J2) appears on the screen.

If no signal is input to the selected connector, “NO INPUT

SIGNAL” appears on the screen. After a few seconds, the monitor

enters the power saving mode. If this happens, switch to the other

connector.

Automatically Sizing and

Centering the Picture

You can easily adjust the picture to fill the screen by

pressing the (auto sizing and centering) button.

Press the button.

The picture automatically fills the screen.

Notes

• This function is intended for use with a computer that provides

a full-screen picture. It may not work properly if the background

color is dark or if the input picture does not fill the screen to the

edges.

• Pictures with an aspect ratio of 5:4 (resolution: 1280 × 1024) are

displayed at their actual resolution and do not fill the

screen to the edges.

• The displayed image moves for a few seconds when the

button is pressed. This is not a malfunction.

Technical Features

Plug & Play

This monitor complies with the DDC1, DDC2B and DDC2Bi

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 or DDC2Bi host system is connected, the

monitor automatically switches to the appropriate standard.

Damper Wires

When viewing a white background, very thin horizontal

lines may be visible on the screen as shown below. These

lines are the shadows of the damper wires and are

characteristic of CRTs that use aperture grilles. The wires

are attached to the aperture grille on the inside of the

Trinitron tube and prevent the vibration of the aperture

grille.

• Check that the power cord is properly connected.

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

• Check that the input switch setting is correct (page 5).

• Check that the video input connector’s pins are not bent or pushed in.

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

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.

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

in their sockets.

• Ensure that no pins are bent or pushed in the video input connector.

• Check that the input switch setting is correct (page 5).

• Check that the graphic board is completely seated in the proper bus slot.

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

(Horizontal: 30 – 121 kHz, Vertical: 48 – 160 Hz)

Refer to your computer’s instruction manual to adjust the video frequency range.

• See “Self-diagnosis Function” (page 20).

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

• Check this manual and confirm that the graphics mode and the frequency you are

trying to operate at is supported. Even if the frequency is within the proper range,

some graphic boards may have a sync pulse that is too narrow for the monitor to sync

correctly.

• Degauss the monitor (page 13).

If you place equipment which generates a magnetic field, such as a loudspeaker, near

the monitor, or you change the direction of the monitor, color may lose uniformity.

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.

• Adjust the landing (page 10).

• If the control lock function is set to ON, set it to OFF using the OPTION OSD

(page 14).

• Adjust the contrast and brightness (page 6).

• Degauss the monitor (page 13).

If you place equipment which generates a magnetic field, such as a loudspeaker, near

the monitor, or you change the direction of the monitor, color may lose uniformity.

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

(page 9).

• If CANCEL MOIRE is ON, the picture may become fuzzy. Decrease the moire

cancellation effect or set CANCEL MOIRE to OFF (page 10).

• Isolate and eliminate any potential sources of electric or magnetic fields. Common

causes for this symptom are electric fans, fluorescent lighting, or 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 the monitor on a different computer in a different room.

• Set the refresh rate on the computer to obtain the best possible picture by referring to

your computer’s manual.

• Eliminate the use of video cable extensions and/or video switch boxes if this symptom

occurs. Excessive cable length or a weak connection can produce this symptom.

• Set CANCEL MOIRE to ON and adjust the degree of moire cancellation until the

moire is at a minimum (page 10).

• 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.

• 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 COLOR

RETURN function, see page 12.

• 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.

• These wires stabilize the vertically striped aperture grille (page 15). 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.

• If the problem persists, call the IBM HelpCenter.

In the US. call 1-800-772-2227

In Canada call 1-800-565-3344
