SAFETY PRECAUTIONS

V-36P903 V-32P903

1. The design of this product contains special hardware, many circuits and components specially for s afety 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. Servic e 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 manufacturer's warranty and will further relieve the manufacturer of r esponsibility for personal injury or property damage resulting therefrom.

3. Many electr ical 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 necess arily be obtained by using replacement c omponents 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 featur es are ident ified 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 Ser vice man ual may c aus e s hoc k, fire, or oth er haz ar ds.

4. Use isolation transformer when hot chassis. The chassis and any sub-chassis c ontained in some products are connect ed to one sid e of the AC power lin e. An isolati on transformer of adequate capacity should be inserted between the product and the AC power supply point while performing any service on s ome products when the HOT chassis is exposed.

5. 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 differenc e of the GND is shown by the LIVE : (") side GND, the 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 appar atus (osc illosc ope 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 br oken.

6. 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).

7. 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 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 det ermine the cause by visual inspection (incorrect installation, cr acked 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 c omplet e product.

8. 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.

9. When service is r equired, obser ve the original lead dr ess. Extra precaution should be given to assure correct lead dress in the high voltage circuit area. Where a short circuit has occurred, those c omponents that indicate evidence of overheating should be replaced. Always use the manufacturer's replacement c omponents.

10. Isolation Check

(Safety for Electrical Shock Hazard)

After re-assembling the product, always perform an isolation check on the expos ed metal parts of the c abinet (antenna terminals, video/audio input and output terminals, Control knobs, metal cabinet, scr ewheads, earphone jack, control shafts, etc.) to be sure the product is s afe to operate without danger of electrical shock.

(1) Dielectr ic 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 1100V AC (r.m.s.) for a period of one second.

(. . . . W ithstand 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 a test equipment not generally fou nd in th e s er vic e trade.

(2) Leakage Current Check

Plug 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 gr ound (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 0.15μ F 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 measur ed 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.).

SELF CHK FUNCTIONS

This model has self-check functions that inform of the failur e of the TV by detecting abnormality. Operational state is always monitored and the identified is memorized on the record.

How to enter the self-check mode

1. During the stand-by mode, turn the power on while pressing

the volume (

How to exit from the SELF CHK mode

1. By using the remote controller unit, turn the power off. At this

time, the f ailure record is cleared.

2. Take off the AC plug from the wall outlet. At this time, the failure record is not cleared.

" SELF CHECK DISPLAY

The self-check results are shown on the following display. Method of indication when the raster is not displayed (Fig.1).

Each failure is shown by turning LED on and off at the specified intervals.

X-ray protection

Over-current protection

LOB protection

" Explanation for activation of self-check functions

For X-ray pr otection, over-current protection and LOB protection, the power of the TV is turned off if NG is detected. Immediately after the power is turned off, POWER LED will be turning on and off. When the power is turned off, you cannot turn the power on again until the AC plug is taken out and put in again.

" Because of the timing of VCC start-up and shut-down of the IC

connecting to the I and off, the operation may be interpreted as an error. In order to avoid the misinterpretation, the self-check functions should be started at about 3 seconds after the power is turned on.

" The latest failure is stored on the record at the end.

The failure record for each check item is counted to the number of 9 at the maximum, W hen more than 9 failures are stored on the record, the counter remains stopped at 9.
