1. SAFETY
PRECAUTIONS
1.
The design of this product contains special hardware, many circuits and components especially for safety purposes. For continued protection, no changes should be made to the original design unless authorized in writing by the manufacturer. Replacement parts must be identical to those used in the original circuits. Service should be performed by qualified personnel only.
9.
2.
Alterations of the design or circuitry of the products should not be made. Any design alterations or additions will void the manufacturer’s warranty and will further relieve the manufacturer of responsibility for personal injury or property damage resulting therefrom.
3.
Many electrical and mechanical parts in the products have special safety-related characteristics. These characteristics are often not evident from visual inspection nor can the protection afforded by them necessarily be obtained by using replacement components rated for higher voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified in the parts list of Service manual. Electrical components having such features are identified by shading on the schematics and by ( ！ ) on the parts list in Service manual. The use of a substitute replacement which does not have the same safety characteristics as the recommended replacement part shown in the parts list of Service manual may cause shock, fire, or other hazards
4.
Don’t short between the LIVE side ground and ISOLATED (NEUTRAL) side ground or EARTH side ground when repairing. Some model’s power circuit is partly different in the GND. The difference of the GND is shown by the LIVE: ( ) side GND, ISOLATED (NEUTRAL): ( ) side GND and EARTH: ( ) side GND. Don’t short between the LIVE side GND and ISOLATED (NEUTRAL) side GND or EARTH side GND and never measure with a measuring apparatus (oscilloscope etc.) the LIVE side GND and ISOLATED (NEUTRAL) side GND or EARTH side GND at the same time. If above note will not be kept, a fuse or any parts will be broken.
5.
If any repair has been made to the chassis, it is recommended that the B1 setting should be checked or adjusted (See ADJUSTMENT OF B1 POWER SUPPLY).
6.
The high voltage applied to the picture tube must conform to that specified in Service manual. Excessive high voltage can cause an increase in X-Ray emission, arcing and possible component damage, therefore operation under excessive high voltage conditions should be kept to a minimum, or should be prevented. If severe arcing occurs, remove the AC power immediately and determine the cause by visual inspection (incorrect installation, cracked or melted high voltage harness, poor soldering, etc.). To maintain the proper minimum level of soft X-Ray emission, components in the high voltage circuitry including the picture tube must be the exact replacements or alternatives approved by the manufacturer of the complete product.
7.
Do not check high voltage by drawing an arc. Use a high voltage meter or a high voltage probe with a VTVM. Discharge the picture tube before attempting meter connection, by connecting a clip lead to the ground frame and connecting the other end of the lead through a 10kΩ 2W resistor to the anode button.
8.
When service is required, observe the original lead dress. Extra precaution should be given to assure correct lead dress in the high voltage circuit area. Where a short circuit has occurred, those components that indicate evidence of overheating should be replaced. Always use the manufacturer’s replacement components.
Isolation Check (Safety for Electrical Shock Hazard) After re-assembling the product, always perform an isolation check on the exposed metal parts of the cabinet (antenna terminals, video/audio input and output terminals, Control knobs, metal cabinet, screw heads, earphone jack, control shafts, etc.) to be sure the product is safe to operate without danger of electrical shock. 10. The surface of the TV screen is coated with a thin film which can easily be damaged. Be very careful with it when handle the TV. Should the TV screen become soiled, wipe it with a soft dry cloth. Never rub it forcefully. Never use any cleaner or detergent on it. (1)

Dielectric Strength Test The isolation between the AC primary circuit and all metal parts exposed to the user, particularly any exposed metal part having a return path to the chassis should withstand a voltage of 3000V AC (r.m.s.) for a period of one second. (…Withstand a voltage of 1100V AC (r.m.s.) to an appliance rated up to 120V, and 3000V AC (r.m.s.) to an appliance rated 200V or more, for a period of one second.) This method of test requires test equipment not generally found in the service trade. Leakage Current Check Plug the AC line cord directly into the AC outlet (do not use line isolation transformers during this check). Using a “Leakage Current Tester”, measure the leakage current from each exposed metal part of the cabinet, particularly any exposed metal part having a return path to the chassis, to a known good earth ground (water pipe, etc.). Any leakage current must not exceed 0.5mA AC (r.m.s.). However, in tropical area, this must not exceed 0.2mA AC (r.m.s.). ●Alternate Check Method Plug the AC line cord directly into the AC outlet ( do not use a line isolation transformer during this check.). Use an AC voltmeter having 1000 ohms per volt or more sensitivity in the following manner. Connect a 1500Ω 10W resistor paralleled by a 0.15μF AC-type capacitor between an exposed metal part and a known good earth ground (water pipe, etc.). Measure the AC voltage across the resistor with the AC voltmeter. Move the resistor connection to each exposed metal part, particularly any exposed metal part having a return path to the chassis, and measure the AC voltage across the resistor. Now, reverse the plug in the AC outlet and repeat each measurement. Any voltage measured must not exceed 0.75V AC (r.m.s.). This corresponds to 0.5mA AC (r.m.s.). However, in tropical area, this must not exceed 0.3V AC (r.m.s.). This corresponds to 0.2mA AC (r.m.s.)

3. REPLACEMENT OF MEMORY IC 1. MEMORY IC. This TV uses memory IC. In the memory IC are memorized data for correctly operating the video and deflection circuits.
2. PROCEDURE FOR REPLACING MEMORY IC (1) Power off Switch the power off and unplug the power cord from AC outlet. (2) Replace IC Be sure to use memory IC written with the initial data values. (3) Power On Plug the power cord into the AC outlet and switch the power on. (4) Check and set SYSTEM default value: 1) Press “MUTE” à “CALL” à “-\--“ à “CALL” à “MUTE” buttons in sequence to enter into factory status. 2) If the memory IC haven’t been written with the initial data, press [Program+] / [Program-] to select item INIT and press [VOLUME+] / [VOLUME-] to start initialize memory IC. 3) Check the setting value of the SYSTEM default value of Table below. If the value is different, select items by [Program+] / [Program-] keys and set value by [VOLUME+] / [VOLUME-] keys. 4) Press “EXIT” button to return to the normal screen.
4. SERVICE ADJUSTMENT Specific operation: use remote controller Press “MUTE” à “CALL” à “-\--“ à “CALL” à “MUTE” buttons in sequence to enter into factory mode. Press [Program+] / [Program-] to select items and press [VOLUME+] / [VOLUME-] key, to make data adjustment of corresponding factory menus. Press “EXIT” key to exit factory mode.
Focus adjustment 1. Receive a crosshatch signal. 2. While watching the screen, adjust the FOCUS VR on the FBT to make the vertical and horizontal lines as fine and sharp as possible.
Geometrical adjustment Receive PAL standard complete pattern signal. Adjustment steps： a) Adjust VSL, to the centre horizontal line just appears from half bottom shadow. b) Adjust VAM, to get 92% of vertical picture contents would be displayed on CRT. c) Adjust VSH, the centre horizontal line corresponds to CRT vertical centre. d) Adjust SCL, to the linearity of P card field is in proper condition. e) Adjust HSH, to get the picture horizontal centre correspond to CRT horizontal centre. Receive NTSC signal and repeat above adjustment.
AGC Adjustment Receive 60dBμ (1mV) VH colour bar pattern signal. Select TOP item. Adjust value, to noise reduce gradually and just disappeared point.
CRT cut off and white balance adjustment a) CRT cut off adjustment 1. Select item VG2B, then adjust value to 32. 2. PRESS “0” key, when the screen shows”VG2” adjust the SCREEN control on Fly back transformer to make the screen show alternating flashing characters of “INSIDE HIGH INSIDE LOW”. b) White balance adjustment 1. Receive a Black and White pattern. 2. Adjust WRP, WRG, WRB items to get colour temperature 9300K ±3 JND. 5
