SAFETY PRECAUTIONS SAFETY-RELATED COMPONENT WARNING! X-RADIATION There are special components used in this color monitor The only potential source of X-radiation is the picture tube. which are important for safety. These parts are marked However, when the high voltage circuitry is operating on the schematic diagram and the replacement properly there is no possibility of an X-radiation problem. -

Page 9: Description Of Block Diagram
DESCRIPTION OF BLOCK DIAGRAM 1. Line Filter & Associated Circuit. 5. X-ray Protection. This is used for suppressing noise of power input line This circuit detects the rectified DC voltage comes flowing into the monitor and/or some noise generated from the FBT pin 4. If the high voltage of the FBT in this monitor flowing out through the power input reaches up to about 30kV (abnormal state), H.V control (IC802) detects. - Page 10 12. High Voltage Output & FBT (Flyback Transformer). 18. Static Convergence Control Circuit. The high voltage output circuit is used for generating This circuit corrects the convergence of the screen by pulse wave to the primary coil of the FBT (Flyback supplying the convergence signal to the 4H (STC) coil Transformer (T701)).

ADJUSTMENT GENERAL INFORMATION 3) EEPROM → ALL CLEAR → Y(Yes) command. All adjustment are thoroughly checked and corrected when the monitor leaves the factory, but sometimesDo not run this procedure unless the several adjustments may be required. EEPROM is changed. All data in EEPROM (mode Adjustment should be following procedure and after data and color data) will be erased. - Page 12 12) Display color 15,0 box pattern(70x70mm) at mode 9. 6.
