SAFETY PRECAUTIONS

V-61S902

1. The design of this product contains special hardware, many circuits and components specially for safety purposes. For continued protection, no changes should be made to the original design unless authorized in writing by the manufacturer. Repl acemen t par ts m ust be i d en tical t o t h ose used in t h e orig i n al 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 manufacturer's warranty and will f urther relieve the manuf acturer of responsibility for personal injury or proper ty damage r esulting therefrom.

3. Many electrical and mechanical parts in the products have special safet y-related charac teris tics . Thes e charac teris tics are oft en not evident from visual i nspec tion nor can th e protec tion afforded by them nec essarily be obtained by using replacement comp onen ts rat ed f or h igh er vol tag e, wat tage, etc . Rep lac ement 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 us e of a substitute replacement which does not

have the same safety characteristics as the recommended repl acemen t part shown in t he part s li st of Ser vice m anual m ay cause shock, fire, or other hazards.

4. Use isolation transformer when hot chassis. The chassis and a n y sub-cha ssi s con t a i n e d i n some pr o d u cts are connected to one side of the AC power line. An isolation tran sform er of ad eq u ate c ap acit y shou l d be i n serted b et w een the product and the AC power supply point while performing any service on some 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 diff erent in the G ND. The diff erence of t he GN D is shown by t h e LIVE : ( " ) side GND, the ISOLATED(NEUTRAL) : (#) side GND and EART H : ( $) side GND. Don't short between the LIVE side GND and ISOLATED(NEUTRAL) side GND or EARTH side GND and neve r measure w ith a me a suring appara tus (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 k ept, a fuse or any pa rts will be broken.

6. If any repair has been made t o the chassis, it is recommended that the B1 setting should be checked or adjusted (See ADJUSTMENT OF B1 POWER SUPPLY).

7. T he 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 voltag e condit ions s hould be k ept to a mini mum, or s hould be prevented. If severe arcing occurs, remove the AC power immediately and determine the cause by visual inspection (incorrec t 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.

8. Do not check high voltage by drawing an arc. Us e 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. Wh en s er vi c e is req u ir ed, ob s erve t he or ig in al lead dr es s . E xtr a prec aution shoul d be g iven to as sur e corr ect lead dres s in the high voltage circuit area. W here a short circuit has occurred, those components that indicate evidence of overheating should be replaced. Always use the manufacturer's replacement components.

10. 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 c abinet, screwheads , earphone jack, control shafts, etc.) to be su r e the p r od uct is s afe to operate with ou t dang er of el ectr ical shock.

(1) Dielectric Strength Test

Th e is olati on b etween the A C pr imar y ci rc ui t and all m etal par ts expos ed 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.

(. . . . Withs tand 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 pe riod of one second.) This method of test requires a test equipment not generally found in the service trade.

(2) Leakage Current Check

Plu g t h e A C lin e cor d di rec t l y i n to th e AC out let (d o n ot us e a l i n e 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 havi n g a return path to the chassis, to a known g ood earth ground (wat er pipe, etc.) . Any l eakage cur rent 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

Plu g t h e A C lin e cor d di rec t l y i n to th e AC out let (d o n ot us e a l i n e isolati on trans former duri ng this check. ). Us e 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 c apaci tor b etween an exposed metal p art an d 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 t he chassis, and measure the AC voltage ac ros s th e resi st or. Now, rever s e the pl ug i n t he AC outlet and repeat each measurement. Any voltage measured must not exc eed 0.75V AC (r .m.s.). This c orresponds to 0.5mA AC (r.m.s.). However , in t ropi cal area, t his must n ot exceed 0. 3 V AC ( r.m . s.). This corresponds to 0.2mA AC (r.m.s.).
