SAFETY PRECAUTIONSIMPORTANT SAFETY NOTICEMany electrical and mechanical parts in this chassis have special safety-related characteristics. These parts are identified by in the Schematic Diagram and Exploded View. It is essential that these special safety parts should be replaced with the same components as recommended in this manual to prevent X-RADIATION, Shock, Fire, or other Hazards. Do not modify the original design without permission of manufacturer.
General GuidanceAn isolation Transformer should always be used during the servicing of a receiver whose chassis is not isolated from the AC power line. Use a transformer of adequate power rating as this protects the technician from accidents resulting in personal injury from electrical shocks. It will also protect the receiver and it's components from being damaged by accidental shorts of the circuitry that may be inadvertently introduced during the service operation. If any fuse (or Fusible Resistor) in this monitor is blown, replace it with the specified. When replacing a high wattage resistor (Oxide Metal Film Resistor, over 1W), keep the resistor 10mm away from PCB. Keep wires away from high voltage or high temperature parts. Due to high vacuum and large surface area of picture tube, extreme care should be used in handling the Picture Tube. Do not lift the Picture tube by it's Neck.
Leakage Current Hot Check (See below Figure)Plug the AC cord directly into the AC outlet. Do not use a line Isolation Transformer during this check. Connect 1.5K/10watt resistor in parallel with a 0.15uF capacitor between a known good earth ground (Water Pipe, Conduit, etc.) and the exposed metallic parts. Measure the AC voltage across the resistor using AC voltmeter with 1000 ohms/volt or more sensitivity. Reverse plug the AC cord into the AC outlet and repeat AC voltage measurements for each exposed metallic part. Any voltage measured must not exceed 0.75 volt RMS which is corresponds to 0.5mA. In case any measurement is out of the limits specified, there is possibility of shock hazard and the set must be checked and repaired before it is returned to the customer.
Leakage Current Hot Check circuit
AC Volt-meter
Leakage Current Cold Check(Antenna Cold Check)With the instrument AC plug removed from AC source, connect an electrical jumper across the two AC plug prongs. Place the AC switch in the on position, connect one lead of ohm-meter to the AC plug prongs tied together and touch other ohm-meter lead in turn to each exposed metallic parts such as antenna terminals, phone jacks, etc. If the exposed metallic part has a return path to the chassis, the measured resistance should be between 1M and 5.2M. When the exposed metal has no return path to the chassis the reading must be infinite. An other abnormality exists that must be corrected before the receiver is returned to the customer.To Instrument's exposed METALLIC PARTS0.15uF

If display Cant , Check connect computer, jig, and set.(1) (3)
2. Specification(1) Because this is not a hot chassis, it is not necessary to use an isolation transformer. However, the use of isolation transformer will help protect test instrument. (2) Adjustment must be done in the correct order. (3) The adjustment must be performed in the circumstance of 25 cC 5 cC of temperature and 65 % 10 % of relative humidity if there is no specific designation. (4) The input voltage of the receiver must keep 100 V ~ 240 V, 50 / 60 Hz. (5) The receiver must be operated for about 5 minutes prior to the adjustment when module is in the circumstance of over 15 cC - In case of keeping module is in the circumstance of 0 cC, it should be placed in the circumstance of above 15 cC for 2 hours - In case of keeping module is in the circumstance of below -20 cC, it should be placed in the circumstance of above 15 cC for 3 hours. 1) Press the POWER ON KEY on R/C for adjustment. 2) Press the ADJ KEY on R/C and enter EZ ADJUST. Select 4. WHITE PATTERN by using D/E(CH +/-) and select White by using F/G(VOL +/-) - Set is activated HEAT run without signal generator in this mode. - Single color pattern (RED / BLUE / GREEN) of HEAT RUN MODE uses to check panel.
