Service work should be performed only after you are thoroughly familiar with all of the following safety checks and servicing guidelines. x Safety Check Care should be taken while servicing this analog color display because of the high voltages used in the deflection circuits. These voltages are exposed in such areas as the associated flyback and yoke circuits. x Fire & Shock Hazard · Insert an isolation transformer between the analog color display and AC power line before servicing the chassis. · When servicing, pay close attention to the original lead dress especially in the high voltage circuit area; 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 original design. · Soldering must be inspected for possible cold solder points, frayed leads, damaged insulation, solder splashes or sharp solder points. Be certain to remove all foreign materials. x Implosion Protection Picture tube in this monitor employs integral implosion protection system, but care should be taken to avoid damage and scratching during installation. Only use same type replacement picture tubes. IMPORTANT SAFETY NOTICE: There are special components used in this analog color display, which are important for safety. These parts are shaded on the schematic diagram and on the replacement parts list. It is essential that these critical parts should be replaced with manufacturer's specified parts to prevent X-Ray, shock, fire or other hazards. Do not modify the original design without getting written permission from DAEWOO ELECTRONICS CO. or this will void the original parts and labor warranty. x X-Ray WARNING: The only potential source of X-Ray is the picture tube. However when the high voltage circuitry is operating properly, there is no possibility of an X-Ray problem. The basic precaution which must be exercised is to keep the high voltage at the following factory recommended level. NOTE: It is important to use an accurate, periodically, calibrated high voltage meter. · To measure the high voltage, use a high-impedance high-voltage meter. Connect(-) to chassis and (+) to the CRT anode button. · Turn the Contrast & Brightness Control fully counterclockwise. · Measure the high voltage. The high voltage meter should indicate the following factory recommended levels. · If the upper meter in
