SAFETY CHECK-OUT
(US Model only)
After correcting the original service problem, perform
the following safety checks before releasing the set to the
customer:
LEAKAGE TEST
The AC leakage fromanyexposed metalpart to earthground
and from all exposed metal parts to any exposed metal part having
a return to chassis, must not exceed 0.5 mA (500 microampere).
Leakage current can be measured by any one of three methods.

1. Check the area of your repair for unsoldered or
poorly-soldered 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 transistors, 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.
1. A commercial leakage tester, such as the Simpson 229 or
RCA WT-540A. Follow the manufacturers' instructions to
use these instructions.
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"
indication is 0.75 V, so analog meters must have an accurate
low voltage scale. The Simpson's 250 and Sanwa
SH-63Trd are examples of passive VOMs that are suitable.
Nearly all battery operated digital multimeters that have a
2V AC range are suitable. (See Fig. A)

Table of Contents
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.
Warning on Power Connection
•Use an appropriate power cord for your local power
supply.
For customers in the U.S.A.
If you do not use an appropriate power cord, the monitor
will not conform to mandatory FCC standards.
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.

• Make sure the power cord is properly connected.
• Make sure the u(POWER) switch is in the “ON” position.
• Try pressing any key on the computer keyboard.
• Make sure your computer is turned on.
• Make sure the video signal cable is properly connected and all plugs are firmly seated in
their sockets.
• Make sure none of the HD15 video input connector pins are bent or pushed in.
• Make sure the video board is completely seated in the proper bus slot.
• Make sure the video frequency range is within that specified for the monitor.
Horizontal: 30 – 70 kHz
Vertical: 50 – 120 Hz
Refer to your computer system’s instruction manual to adjust the video frequency range.
• If you are using a video signal cable adapter, make sure it is the correct type.
• Run the SELF TEST function:
1. Turn off the monitor and disconnect the video cable from the computer.
2. Turn on the monitor and wait five seconds. The “NO INPUT SIGNAL” message
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.
Additional Information
INFORMATION
OUT OF SCAN RANGE
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.

Getting Started
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
One fine horizontal line (wire) is
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 6).
• 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.
• This wire stabilizes the vertically striped aperture grille (page 3). 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).

2-4. PICTURE TUBE REMOVAL
Turn up one side of the rubber cap in
the direction indicated by arrow . When one side of the rubber cap sepa-
rates from the anode button, the anode-
cap can be removed by turning the rub-
ber cap and pulling it in the direction of
arrow .
Use your thumb to pull the rubber cap
firmly in the direction indicated by
arrow .
HOW TO HANDLE AN ANODE-CAP
REMOVAL OFTHE 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.
REMOVAL PROCEDURES
Do not use sharp objects which may cause damage to the surface
of the anode-cap.
Do not squeeze the rubber covering too hard to avoid damaging
the anode-cap. A material fitting called a shatter-hook terminal is
built into the rubber.
Do not force turn the foot of the rubber cover. This may cause the
shatter-hook terminal to protrude and damage the rubber.
