Safety Precautions
Safety Precautions
1.
1. The design of this product contains special hardware, many circuits and components specially for safety purpo-ses. 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.
2. Alterations of the design or circuitry of the products should not be made. Any design alterations or additions will void the manufacturers 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 compo-nents 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. Dont short between the LIVE side ground and ISOLATED (NEUTRAL) side ground or EARTH side ground when repairing. Some models 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. Dont 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 adjus-ted (See ADJUSTMENT OF B1 POWER SUPPLY).
6. The high voltage applied to the picture tube must conform with that specified in Service manual. Excessive high voltage can cause an increase in X-Ray emission, arcing and possible component damage, therefore opera-tion 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 10k 2W resitor 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 manufacturers replacement components.
9. 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, screwheads, earpho-ne 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 forcefu-lly. Never use any cleaner or detergent on it.
(a) Dielectric Strength TestThe isolation between the AC primary circuit and all metal parts exposed to the user, particularly any expo-sed 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 periode of one second.)This method of test requires a test equipment not generally found in the service trade.
(b) Leakage Current CheckPlug the AC line cord directly into the AC outlet (do not use a line isolation transformer 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 MethodPlug 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 1500 10W resistor paralleled by a 0.15F 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.)

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.When replacing memory IC, be sure to use IC written with the initial value of data.
2. PROCEDURE FOR REPLACING MEMORY IC(1) Power offSwitch the power off and unplug the power cord from AC outlet.(2) Replace ICBe sure to use memory IC written with the initial data values.(3) Power OnPlug the power cord into the AC outlet and switch the power On.(4) Check and set SYSTEM default value:
1) Press MENU key and then press number 6 4 8 3 key on the Remote control unit. Or Press Factory key on the Remote control unit for factory used.
2) The Factory / M will be displayed on the screen.3) IN M MODE,PRESSMUTEKEY WILL BE ENTER M0.THEN PRESSMUTEKEY WILL ENTER
M1 AND M2.4) IN M2 SELECT SETUP SELECT TO 1,THEN PRESSMUTEKEY WILL BE ENTERM3 TO M9.5) Check the setting value of the SYSTEM default value of Table below. If the value is different, select items
by [CH+]/[CH-] keys and set value by [VOL+]/[VOL-] keys.6) Press STANDBY key again and return to the normal screen.

PURITY ADJUSTMENT
1. Demagnetize CRT with the demagnetizer.
2. Loosen the retainer screw of the deflection yoke.
3. Remove the wedges.
4. Input a green raster signal from the signal generator, and turn the screen to green raster.
5. Move the deflection yoke backward.
6. Bring the long lug of the purity magnets on the short lug and position them horizontally. (Fig2)
7. Adjust the gap between two lugs so that the GREEN RASTER will come into the center of the screen. (Fig. 3)
8. Move the deflection yoke forward, and fix the position of the deflection yoke so that the whole screen will become green.
9. Insert the wedge to the top side of the deflection yoke so that it will not move.
10. Imput a crosshatch signal.
11. Verify that the screen is horizontal.
12. Input red and blue raster signals, and make sure that purity is properly adjusted.

STATIC CONVERGENCE ADJUSTMENT
1. Input a crosshatch signal.
2. Using 4-pole convergence magnets, overlap the red and blue lines in the center of the screen (Fig. 1) and turn them to magenta (red/blue).
3. Using 6-pole convergence magnets, overlap the magenta (red/blue) and green lines in the center of the screen and turn them to white.
4. Repeat 2 and 3 above, and make the best convergen-ce.
DYNAMIC CONVERGENCE ADJUSTMENT
1. Move the deflection yoke up and down and overlap lines in the periphery. (Fig. 2)
2. Move the deflection yoke left to right and overlap the lines in the periphery. (Fig. 3)
3. Repeat 1 and 2 above, and make the best convergen-ce.
After adjustment, fix the wedge at the original position.Fasten the retainer screw of the deflection yoke.Fix the 6 magnets with glue.
