2. PRECAUTIONS AND NOTICES
2-1 SAFETY PRECAUTIONS
1. Observe all caution and safety related notes located inside the display cabinet.
2. Operation of the display with the cover removed, may cause a serious shock hazard from the
display power supply. Work on the display should not be attempted by anyone who is not
thoroughly familiar with precautions necessary when working on high voltage equipment.
3. Do not install, remove or handle the picture tube in any manner unless shatter-proof goggles are
worn. People who are not so equipped should be kept away while handling picture tube. Keep
picture tube away from the body while handling.
4. The picture tube is constructed to limit X-RAY radiation to 0.5 mR/HR. For continued protection,
use the designated replacement tube only, and adjust the voltages so that the designated
maximum rating at the anode will not be exceeded.
5. Symbol “ ” means safety relative parts. The use of substitute replacement parts which do not
have the same characteristics as specified in the parts list may create shock, fire or explode etc.
6. Before returning a serviced display to the customer, a thorough safety test must be performed to
verify that the display is safe to operate without danger or shock. Always perform an AC leakage
current check on the exposed metallic parts of the cabinet, such as screw heads.
Test method for current leakage is described as follow.
(a) Plug the AC line cord directly into rated AC outlet (do not use a line isolation transformer
during this check).
(b) Use an AC voltmeter having 5000 ohms per volt or with more sensitivity in the following
manner: Connect a 1500 ohms 10 Watt resistor, paralleled by a 0.15UF, AC type capacitor
between a known good earth ground (water pipe, conduit, etc.) and the exposed metallic
parts simultaneously. Measure the AC voltage across the combination of 1500 ohms
resistor and 0.15UF capacitor.
(c) Reverse the AC plug at the AC outlet and repeat AC voltage measurements for each
exposed metallic part.
(d) Voltage measured must not exceed 0.5 volts RMS. This corresponds to 0.35 milliamp AC.
Any value exceeding this limit constitutes a potential shock hazard and must be corrected
immediately.
2-2 PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in this chassis have special safety visual inspections and the
protection afforded by them cannot necessarily be obtained by using replacement components rated
for higher voltage, wattage, etc. Before replacing any of these components read the parts list in this
manual carefully. The use of substitute replacement parts which do not have the same safety
characteristics as specified in the parts list may create shock, fire, X-RAY radiation or other hazards.
5
2-3 SERVICE NOTES
1. When replacing parts or circuit boards, clamp the lead wires around terminals before soldering.
2. When replacing a high wattage resistor (more than 1/2W of metal oxide film resistor) in circuit
board, keep the resistor about 10mm (1/2 in) away from circuit board.
3. Keep wires away from high voltage or high temperature components.
4. Keep wires in their original position so as to reduce interference.
2-4 HIGH VOLTAGE WARNING
Operation of monitor outside of cabinet or with back removed may cause a serious shock hazard.
Work on this model should only be performed by those who are thoroughly familiar with precautions
necessary when working on high voltage equipment.
Exercise care when servicing this chassis with power applied. Many B plus and high voltage
terminals are exposed which, if carelessly contacted, can cause serious shock or result in damage to
the chassis. Maintain interconnecting ground lead connections between chassis and picture tube dag
when operating chassis.
Certain HV failures can increase X-ray radiation. Monitor should not be operated with HV levels
exceeding the specified rating for the chassis type. The maximum operating HV specified for the
chassis used in this monitor is
25.0KV ± 1KV
with a line voltage of 120/240 VAC. Higher voltage may also increase possibility of failure in HV
supply.
It is important to maintain specified values of all components in the horizontal and high voltage
circuits and anywhere else in the monitor that could cause a rise in high voltage or operating supply
voltages. No changes should be made to the original design of the monitor. Components shown in
the shaded areas on the schematic should be replaced with exact factory replacement parts. The
use of unauthorized substitute parts may create a shock, fire or other hazard.
To determine the presence of high voltage, use accurate, high impedance, HV meter connected
between second anode lead and CRT dag grounding device. When servicing the High Voltage
System, remove static charge from it by connecting a 10K ohm resistor in series with an insulated
wire (such as a test probe) between picture tube dag and 2nd anode lead.(AC line cord disconnected
from AC power outlet.)
The picture tube used in this monitor employs integral implosion protection. Replace with tube of the
same type number for continue safety. Do not lift picture tube by the neck. Handle the picture tube
only after discharging the high voltage completely.

3. OPERATING INSTRUCTIONS
This procedure gives you instructions for installing and using the Color display.
1. Position the display on the desired operation and plug the power cord into a convenient AC
outlet. Three-wire power cord must be shielded and is provided as a safety precaution as it
connects the chassis and cabinet to the electrical conduit ground. If the AC outlet in your
location does not have provisions for the grounded type plug, the installer should attach the
proper adapter to ensure a safe ground potential.
2. Connect the 15-pin color display shielded signal cable to your signal system device and lock
both screws on the connector to ensure firm grounding. The connector information is as follow:

5. CIRCUIT DESCRIPTION
5-1 MICRO CONTROLLER CIRCUIT
MICRO Controller
The IC101 contains a 8031 8-bit CPU core, 60K bytes of RAM, 16K bytes of ROM,14 channel 8 bit
PWM D/A converters, 2 channel A/D converters for key detection,0.5sec watch-dog timer, internal Hsync and V-sync signals processor providing mode detection, watch- dog timer preventing system from
abnormal operation, and an I²C bus interface.
H/V sync signals processor
The functions of the sync processor include polarity detection, H-SYNC & V-SYNC signals counting,
Programmable SYNC signals output, free running signal generator. Pin41/Pin42 are for the H-SYNC
and V-SYNC input, Pin34/Pin33 will output the same signal as input sync signal without delay, and the
polarity are setting in the positive. When no signal input, the Pin32 will output a 60Hz V-SYNC free run
signal. The Pin33 will output a 48KHz H-SYNC free run signal. for the monitor testing use.
5-2 DEFLECTION CIRCUIT
The deflection circuit is achieved by a high performance and efficient solution IC 401 (STV 9118) for
this monitor. The concept is fully DC controllable and can be used in applications with a microcontroller solutions.
The STV9118 provides sync. Processing with full auto sync. Capability, a flexible SMPS block and an
extensive set of geometry control facilities. Further the IC generates the drive waveforms for DC
coupled vertical boosters to the STV9118.
Horizontal Oscillator
The oscillator is of the relaxation type and requires a capacitor of 1nF C405 at pin29.
PLL 1 Phase Detector
The phase detector is a standard one using switched current sources. It compares the middle of Hsync. with a fixed point on the oscillator saw-tooth voltage. The PLL loop filter R411,C437,C435 is
connected to Pin9.
PLL2 Phase Detector
The PLL2 detector thus compensates for the delay in the external H-deflection circuit by adjusting the
phase of the HDRV output pulses. The phase between H-flyback and H-sync can be controlled at pin5.
X-ray Protection
12
The X-ray protection input pin25 provides a voltage detector with a precise threshold. If the voltage
exceeds this threshold for a certain time, an internal latch switches the whole IC into protection mode.
In this mode several pins are forced into defined states:
Vertical Oscillator
The vertical free –running frequency is determined by the resistor C610 at pin19. Usually the freerunning frequency should be lower than the minimum trigger frequency.
