SAFETY PRECAUTIONS

SAFETY-RELATED COMPONENT WARNING! There are special components used in this color monitor which are important for safety. These parts are marked on the schematic diagram and the replacement parts list. It is essential that these critical parts should be replaced with the manufacturer's specified parts to prevent X-radiation, shock, fire, or other hazards. Do not modify the original design without obtaining written permission from manufacturer or you will void the original parts and labor guarantee. CAUTION: No modification of any circuit should be attempted. Service work should be performed only after you are thoroughly familiar with all of the following safety checks and servicing guidelines. X-RADIATION The only potential source of X-radiation is the picture tube. However, when the high voltage circuitry is operating properly there is no possibility of an X-radiation problem. The basic precaution which must be exercised is keep the high voltage at the factory recommended level; the normal high voltage is about 25.8kV. The following steps describe how to measure the high voltage and how to prevent Xradiation. Note : It is important to use an accurate high voltage meter calibrated periodically. To measure the high voltage, use a high impedance high voltage meter, connect () to chassis and (+) to the CDT anode cap. Set the brightness control to maximum point at full white pattern. Measure the high voltage. The high voltage meter should be indicated at the factory recommended level. If the meter indication exceeds the maximum level, immediate service is required to prevent the possibility of premature component failure. To prevent X-radiation possibility, it is essential to use the specified picture tube.
SAFETY CHECK Care should be taken while servicing this color monitor because of the high voltage used in the deflection circuits. These voltages are exposed in such areas as the associated flyback and yoke circuits. FIRE & SHOCK HAZARD An isolation transformer must be inserted between the color monitor and AC power line before servicing the chassis. In servicing, attention must be paid to the original lead dress specially in the high voltage circuit. If a short circuit is found, replace all parts which have been overheated as a result of the short circuit. All the protective devices must be reinstalled per the original design. Soldering must be inspected for the cold solder joints, frayed leads, damaged insulation, solder splashes, or the sharp points. Be sure to remove all foreign materials. IMPLOSION PROTECTION All used display tubes are equipped with an integral implosion protection system, but care should be taken to avoid damage and scratching during installation. Use only same type display tubes.

Circuit Board Foil Repair Excessive heat applied to the copper foil of any printed circuit board will weaken the adhesive that bonds the foil to the circuit board causing the foil to separate from or "lift-off" the board. The following guidelines and procedures should be followed whenever this condition is encountered. At IC Connections To repair a defective copper pattern at IC connections use the following procedure to install a jumper wire on the copper pattern side of the circuit board. (Use this technique only on IC connections). 1. Carefully remove the damaged copper pattern with a sharp knife. (Remove only as much copper as absolutely necessary). 2. carefully scratch away the solder resist and acrylic coating (if used) from the end of the remaining copper pattern. 3. Bend a small "U" in one end of a small gauge jumper wire and carefully crimp it around the IC pin. Solder the IC connection. 4. Route the jumper wire along the path of the out-away copper pattern and let it overlap the previously scraped end of the good copper pattern. Solder the overlapped area and clip off any excess jumper wire.
At Other Connections Use the following technique to repair the defective copper pattern at connections other than IC Pins. This technique involves the installation of a jumper wire on the component side of the circuit board. 1. Remove the defective copper pattern with a sharp knife. Remove at least 1/4 inch of copper, to ensure that a hazardous condition will not exist if the jumper wire opens. 2. Trace along the copper pattern from both sides of the pattern break and locate the nearest component that is directly connected to the affected copper pattern. 3. Connect insulated 20-gauge jumper wire from the lead of the nearest component on one side of the pattern break to the lead of the nearest component on the other side. Carefully crimp and solder the connections. CAUTION: Be sure the insulated jumper wire is dressed so the it does not touch components or sharp edges.

DESCRIPTION OF BLOCK DIAGRAM
1. SMPS(Switching Mode Power Supply) When you turn on the power switch, the operating fprocedure is as follows:
1) The AC line voltage is rectified by the bridge diode D900. 2) The control IC(IC901) starts switching and generates switch pulse in the primary turn of the SMPS transformer(T901) 3) The switching pulses of the primary turns are induced to the secondary turns of the transformer by the turn ratio. This pulses are rectified by each diode(D971, D961(D962),D951,D942,D941) 4) Each rectified DC voltage(80V, 50V, 15V, 13V,6.3Vand 5V) 2. Over Voltage Protection Circuit When the input of IC901 Vin (pin 4) is more than 22V, all the secondary voltages of the SMPS transformer (T901) down to low value 3. Display Power Management Circuit(DPM) 1) STAND-BY & SUSPEND Mode When no input of horizontal or vertical sync Q951, Q941 are turned off and Q952,Q942 are turned off. Then input power consumption is below 5 watts. 2) OFF Mode When no input of horizontal and vertical sync Q951, Q941 are turned off and Q952, Q942 are turned off. Then input power consumption is below 5 watts. 4. Microprocessor Control & Horizontal and Vertical Sync Processor Circuit The operating procedure is as follows ; 1) There is Horizontal & Vertical process function in Microprocessor.(IC401) 2) Microprocessor (IC401) discriminates the operating mode from the sync polarity and resolution. 3) After microprocessor reads these adjusted mode data stored at EEPROM, it controls operating mode data through IIC 4) Users can control screen condition by the OSD Select,Up, Down, Left, Right, Exit. 5. D/D Converte r Circuit. To obtain constant high voltage, this circuit supplies controlled DC voltage for FBT and horizontal deflection circuit according to the horizontal sync frequency. 13. OSD (On Screen Display) Circuit. This circuit displays information of the monitor`s status on the screen. 14. Video Processor Circuit. Video processor circuit consists of the video drive output block. The video drive IC(IC302) receives the video signal from PC. The gain of each channel is controlled by MICOM through IIC. The cut-off circuit compensate different voltage of each channel between the cathode and the G1 of the CDT. 6. X-RAY Protection Circuit When the high Voltage reaches to 29kV in an abnormal case, the high voltage detector circuit, R818,D721,C739-1 R416, C409 start operation to shut down high voltage circuit. 7. Horizontal S-correction Circuit. This circuit corrects the horizontal linearity for each horizontal sync frequency. 8. Horizontal drive and Output Circuit. This circuit is a horizontal deflection amplifier for raster scan. 9. ABL Circuit This circuit limits the beam-current for the reliability of CDT 10. Vertical Output Circuit This circuit takes the vertical ramp wave from the TDA4867J (IC601) and perform the vertical deflection by supplying the saw-tooth wave current to the vertical deflection yoke. 11. Blanking and Brightness Control Circuit. Blanking circuit eliminates the retrace line by supplying a negative pulse wave to the G1 of the CDT. Brightness control circuit is used for control of the screen brightness by changing the DC level G1. 12. Image Rotation (Tilt) Circuit. This circuit corrects the tilt of the screen by supplying the image rotation signal to the tilt coil which is attached near the deflection yoke of the CDT.
