2. PRECAUTIONS AND NOTICES
2-1 SAFETY PRECAUTIONS
1. Observe all caution and safety related notes located inside the disp lay 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 thorou ghly familiar with precautio ns necessar y
when working on hi gh vo lta ge eq uipment.
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. Before returning a serviced displa y 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 canno t ne cessar il y be ob taine d by usi n g rep lace ment co mpone nts rate d fo r hi gher volta ge, watta ge, etc. Befo re
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.
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 or iginal 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
26KV ± 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 an 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 sa fet y. Do not lif t pi ctur e tub e b y t he nec k. H and le t he p ict ure t ube onl y aft er disc harg ing t he hig h vo ltage
completely.

3. OPERATING INSTRUCTIONS
This procedure gives you instructions for installing and using the C787 color display.
1. Position the display on the desired operation and plug the p ower 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 c onduit grou nd. If the A C outlet in yo ur locatio n does not ha ve provisio ns for the gr ounded type p lug,
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:

for the monitor testing use.
Page 13

On Screen Display Controller
The IC103 is designed for display the built-in characters or fonts onto monitor screen. The display operation is by
transforming data and control information from micro controller to RAM through a serial data interface.
Pin2 is used to control the internal oscillator frequency by DC voltage input from external low pass filter (R125, C114,
R161) and filter (R126, C115) is used to regulate the appropriate bias current for internal oscillator the resonate at
specific dot frequency.
Pin5 is input the horizontal fly back pulse, for PLL generator tracking.
Pin6 is left floating, I2C bus is enabled. Otherwise the SPI bus i s enabled.
Pin7 the external data transfer through this pin to internal display registers and control re gi sters
Pin8 the clock-input pin is used to synchronize the data transfer.
Pin10 is input the vertical flyback pulse for synchronizing the vertical po sition.
Pin12 is output a blanking signal to cut off e xternal R.G.B signals of VGA while this chip is displaying c haracters or
windows.
Pin13, Pin14, Pin15 is used to output the OSD (B.G.R) video signal.
5-2 DEFLECTION CIRCUIT
The deflection circuit is achieved by a high performance and efficient solution IC 401 (TDA4856) for this monitor. The
concept is fully DC controllable and can be used in applications with a micro-controller solutions.
The TDA 4856 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 TDA
4866 [ref Page-28].
Horizontal Oscillator
The oscillator is of the relaxation type and requires a capacitor of 10nF C403 at pin 29. The maximum oscillator
frequency is determined by a resistor R403 form pin 28 to ground. A resistor R402 from pin27 to pin28 defines the
frequenc y range.
PLL 1 Phase Detector
The phase detector is a standard one using switched current sources. It compares the middle of H-sync. with a fixed point
on the oscillator saw-tooth voltage. The PLL loop filter c401, R401, C402 is connected to Pin26.
PLL2 Phase Detector
This phase detector is similar to the PLL1 detector and compares the line flyback pulse at pin 1 with the oscillator sawtooth voltage. The PLL2 detector thus compensate s 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 pin30.
X-ray Protection
The X-ray protection input pin2 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 for ced into
defined states:
Pin7 (HDRV) is floating
Pin6 (BDRV) is floating
Pin12, 13 ( VOUT 1, 2) are floating
Pin16 (CLBL) provides a continuous blanking signal.
Vertical Oscillator
The vertical free –running frequency is determined by the resistor R608 at pin23 and capacitor C604 at pin24. Usually the
free-running frequency should be lower than the minimum trigger frequency.
