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 necessarywhen 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 arenot so equipped should be kept away while handling picture tube. Keep picture tube away from the body whilehandling.

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 have no 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 partsof 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 exceedingthis 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 bythem cannot necessarily be obtained by using replacement components rated for higher voltage, wattage, etc. Beforereplacing any of these components read the parts list in this manual carefully. The use of substitute replacement parts whichdo not have the same safety characteristics as specified in the parts list may create shock, fire, X-RAY radiation or otherhazards.

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 resistorabout 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


7/44

To determine the presence of high voltage, use accurate, high impedance, HV meter connected between second anode leadand CRT dag grounding device. When servicing the High Voltage System, remove static charge from it by connecting a10K ohm resistor in series with an insulated wire (such as a test probe) between picture tube dag and 2nd anode lead.(ACline 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 forcontinue safety. Do not lift picture tube by the neck. Handle the picture tube only after discharging the high voltagecompletely.

3. OPERATING INSTRUCTIONS

This procedure gives you instructions for installing and using the 5G Color display.

1. Position the display on the desired operation and plug the power cord into a convenient AC outlet. Three-wire powercord must be shielded and is provided as a safety precaution as it connects the chassis and cabinet to the electricalconduit 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:

3. Apply power to the display by turning the power switch to the "ON" position and allow about thirty seconds for

display tube warm-up. The Power-On indicator lights when the display is on.4. With proper signals feed to the display, a pattern or data should appear on the screen, adjust the brightness and contrast

5. CIRCUIT DESCRIPTION

5-1 MICRO CONTROLLER CIRCUIT

MICRO Controller

The IC101 contains a 6502 8-bit CPU core, 512 bytes of RAM, 16K bytes of ROM,14 channel 8 bit PWM D/A converters, 2channel A/D converters for key detection, one 8 bit pre-loadable base timer, internal H-sync 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 SYNCsignals output, free running signal generator. Pin39/Pin40 are for the H-SYNC and V-SYNC input, Pin32/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 willoutput a 61Hz or 70Hz V-SYNC free run signal. The Pin33 will output a 62.5KHz or 48KHz H-SYNC free run signal. for themonitor testing use.

On Screen Display Controller

The IC801 is designed for display the built-in characters or fonts onto monitor screen. The display operation is by transformingdata 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 (R809, C818)Pin24 is input the horizontal fly back pulse, for PLL generator tracking.Pin23 is left floating, I2C bus is enabled. Otherwise the SPI bus is enabled.Pin14, Pin15, Pin16 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 (TDA4841) for this monitor. Theconcept is fully DC controllable and can be used in applications with a micro-controller solutions.

The TDA4841 provides sync. Processing with full auto sync. Capability, a flexible SMPS block and an extensive set ofgeometry control facilities. Further the IC generates the drive waveforms for DC coupled vertical boosters to the TDA4863A.

Horizontal Oscillator

The oscillator is of the relaxation type and requires a capacitor of 10nF C404 at pin29. The maximum oscillator frequency isdetermined by a resistor R432 form pin 28 to ground. A resistor R412 from pin27 to pin28 defines the frequency 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 onth ill t t th lt Th PLL l filt C435 R413 C437 i t d t Pi 26
