2. PRECAUTIONS AND NOTICES
2-1 SAFETY PRECAUTIONS 1. 2. 3. 4. Observe all caution and safety related notes located inside the display cabinet. 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. 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. 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. Symbol " ! " means safety relative parts. The use of substitute replacement parts which do not
5. 6.
have the same characteristics as specified in the parts list may create shock,fire or explode etc.
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.

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. 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.

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 24.5KV ± 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.

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, 2 channel 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 SYNC signals 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 will output a 72Hz V-SYNC free run signal. The Pin33 will output a 48KHz H-SYNC free run signal. for the monitor testing use. On Screen Display Controller The IC803 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 (R815) and filter (R876, C867) 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 is enabled. Pin7 the external data transfer through this pin to internal display registers and control registers Pin8 the clock-input pin is used to synchronize the data transfer. Pin10 is input the vertical flyback pulse for synchronizing the vertical position. Pin12 is output a blanking signal to cut off external R.G.B signals of VGA while this chip is displaying characters or windows. Pin13, Pin14, Pin15 is used to output the OSD (B.G.R) video signal.

DEFLECTION CIRCUIT The deflection circuit is achieved by a high performance and efficient solution IC 401 (STV6888) for this monitor. The concept is fully DC controllable and can be used in applications with a micro-controller solutions. The STV6888 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 TDA9302H. Horizontal Oscillator The oscillator is of the relaxation type and requires a capacitor of 1nF C409 at pin6. The free running frequency is determined by a resistor R412 5.1K form pin8 to ground. 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 C435, C437, R411 is connected to Pin9. PLL2 Phase Detector This phase detector is similar to the PLL1 detector and compares the line flyback pulse at pin 12 with the oscillator sawtooth voltage. 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 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: Pin28 (BDRV) is floating Pin26 (HDRV) is floating Pin21, 23 ( VOUT 1, 2) are floating Vertical Oscillator The vertical free running frequency is determined by the capacitance C613 at pin22. Usually the free-running frequency should be lower than the minimum trigger frequency.
