After correcting the original service problem, perform the following safety checks before releasing the set to the customer:
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.

LEAKAGE TEST
The AC leakage from any exposed metal part to earth ground
and from all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 0.5 mA (500
microampers).
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” indication is 0.75 V, so analog meters must have an accurate lowvoltage 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)

Precautions
Warning on power connections
• Use the supplied power cord. If you use a different power cord,
be sure that it is compatible with your local power supply.
For the customers in the U.S.A.
If you do not use the appropriate cord, this monitor will not
conform to mandatory FCC standards.
• Before disconnecting the power cord, wait at least 30 seconds
after turning off the power to allow the static electricity on the
screen’s surface to discharge.
• After the power is turned on, the screen is demagnetized
(degaussed) for about 3 seconds. This generates a strong
magnetic field around the screen which may affect data stored
on magnetic tapes and disks placed near the monitor. Be sure to
keep magnetic recording equipment, tapes, and disks away
from the monitor.
Installation
Do not install the monitor in the following places:
• on surfaces (rugs, blankets, etc.) or near materials (curtains,
draperies, etc.) that may block the ventilation holes
• near heat sources such as radiators or air ducts, or in a place
subject to direct sunlight
• in a place subject to severe temperature changes
• in a place subject to mechanical vibration or shock
• on an unstable surface
• near equipment which generates magnetism, such as a
transformer or high voltage power lines
• near or on an electrically charged metal surface
Maintenance
• 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.
• 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 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
benzene.

Technical Features
Preset and user modes
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 page i 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 – 107 kHz (GDMF400) or 30 – 121 kHz (GDM-F500), vertical: 48 – 160 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.
Note for Windows users
For Windows users, check your video board manual or the utility
program which comes with your graphic board and select the
highest available refresh rate to maximize monitor performance.
Power saving function
This monitor meets the power-saving guidelines set by VESA,
E
NERGY
S
TAR, and NUTEK. If the monitor is connected to a
computer or video graphics board that is DPMS (Display Power
Management Signaling) compliant, the monitor will
automatically reduce power consumption in three stages as shown
below.
* Figures reflect power consumption when no USB compatible
peripherals are connected to the monitor.
**When your computer enters the “active off” mode, the input signal is
cut and NO INPUT SIGNAL appears on the screen. After the time set
in “Changing the power saving delay time.” (page 14) has elapsed, the
monitor enters the power saving mode.
To change the power saving delay time
See page 14.
Troubleshooting
Before contacting technical support, refer to this section.
If thin lines appear on your screen
(damper wires)
The lines you are experiencing on your screen are normal for the
Trinitron monitor and are not a malfunction. These are shadows
from the damper wires used to stabilize the aperture grille and are
most noticeable when the screen’s background is light (usually
white). 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.
On-screen messages
If there is something wrong with the input signal, one of the
following messages appears on the screen. To solve the problem,
see “Trouble symptoms and remedies” on page 16.
1
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, or that no signal is input from
the selected connector (HD15 or BNC).

Note: Hand degauss
This model has an automatic earth magnetism correction function by using an earth magnetism sensor
and a LCC coil. When using a hand degauss while monitor (LCC coil) is being operated, it sometimes
gets magnetized, and the system may not work properly as a result.
• Landing Rough Adjustment
1. Enter the full white signal. (or the full black dots signal).
2. Adjust the contrast to the maximum.
3. Make the screen monogreen.
Note: Off the outputs from R ch and B ch of SG.
4. Reverse the DY, and adjust coarsely the purity magnet so
that a green raster positions in the center of screen.
5. Adjust the tilt of DY, and fix lightly with a clamp.
Note: “TILT” shall be set at 128.
• Landing Fine Adjustment
1. Put the set inside the Helmholtz coil. (“LCC SW” = “12”)
2. Input the single green signal and set the CONT control to
MAX.
Note: After the W/B adjustment with 9300K, measure an aver-
age of ΣIk when a full white signal is entered in the CONT
MAX/BRT CENT status. Then make adjustment so that
the specified screen can be attained after aging for 2 hours
with Ik equivalent to 30% of the average value.
3. Demagnetize the metal part of the chassis with the hand degausser and coil degausser, and the CRT surface with the
hand degausser.
Input AC 230V to AC IN, turn on and off the power to perform auto degaussing. (Perform auto degaussing by setting
“MON CON REG2”=152. Return to the original value after
use.)
Demagnetize the CRT surface with the hand degausser
again.
Note:

6. Adjust the DY position and purity, and the DY tilt, and landing of the center and 4 corners with the landing checker.
• Write terrestrial magnetism sensor reading VX and VY to
“LCC VX” and LCC VY” respectively. Adjust the landing by moving “LCC NS”, “LCC LT”, “LCC LB”, “LCC
RT” and “LCC RB”. However, the register adjustment
must be limited within the following range.
“LCC NS”128 ± 15
“LCC LT”, “LCC LB”, “LCC RT”, “LCC RB”
After adjustment, set “LCC SW” to “13” and save the service data.

* Adjustment and measurement should be made at the points
one inch inside the fluorescent screen.
7. Insert wedges to make the DY neck stand upright without
moving it.
At this time, without shaking the DY, firmly insert the
wedges.
8. Check the landing of each corner, and if it does not satisfy
the specification, adjust the landing of four corners using
“LCC LT“, “LCC LB”, “LCC RT” and “LCC RB”.
However, the register adjustment must be limited within the
following range.
