SAFETY PRECAUTIONS

1. The d esign of th is prod uct conta ins sp ecial hard ware, many

circuit s and components specially for safety purposes. For

con tinued prot ection , n o chan g es sh ou ld b e ma de to the o riginal

d esign unless a uth orized in writing by th e manu fact urer.

Replacem en t p arts must b e id ent ic al to thos e u sed in th e or igin al

circu it s. S er vice sho uld be p er formed by qu alif ied pers on nel

on ly.

2. Alte r ation s of t he desig n or circuitry of t he pr od ucts should not be

made. Any design alterations or additions will void the

manu fact urer's warra nt y and will f urth er r elieve t he manu factu rer

of r esponsib ility for perso na l injury or p r op erty d am ag e r esult ing

th er efrom.

3. Man y e lectrical an d m echanica l parts in th e pr od ucts ha ve

special safety-related characteristics. T hese characteristics are

oft en no t e viden t f r om visua l insp ection n or can t he pro tect io n

aff orde d by th em nece ssarily b e ob tain ed b y u sin g r ep lacem en t

compo ne nts rated f or highe r vo ltag e, watt ag e, etc. Rep lacement

p arts whic h ha ve th ese sp ecial s afet y ch aract erist ics ar e

identified in the parts list of Servic e manual. El ec tric al

components having su ch features are identified by shading

on the sche matic s and by (!

!!

! ) on the parts list in Service

manual. The us e of a sub stitu te rep lacemen t which do es not

h ave th e same saf ety charact erist ics as t he reco mmende d

replac ement par t shown in th e p ar ts list of S ervice m an ual may

cause shock, fire, or other hazards .

4. Do n't shor t 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

diff erenc e of th e G ND is shown b y th e LIV E : ( ") side GND, the

ISO LATE D(NEUTRAL) : (#) side G ND and EARTH : ($) side

GND. Don't short b et ween th e LIV E sid e GND an d

ISO LATE D(NEUTRAL) side GND or EARTH side GND and

n ever measure wit h a m ea suring a ppa ratus (oscilloscope etc.)

th e LI VE sid e GND an d IS OLA TED(NE UTRAL ) side G ND or

EARTH side GND at th e s ame 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

th at t he B1 set ting should be checked or adju ste d (Se e

ADJUSTMENT OF B 1 POWE R SUPPL Y).

6. The high volta ge app lie d t o th e pictu re tu be mu st con form wit h

th at sp ecified in S er vice man ual. E xcessive h igh vo lt ag e can

cau se an incr e ase in X-Ray emission , arcing an d possib le

component damage, therefore operation under excessive high

voltage conditions should be kept to a minimum, or should be

preve nt ed. If s ever e arc in g occurs, r em ove t he AC power

immed iate ly an d de termine th e cause b y visua l inspect ion

(in cor r ect installat ion, cracke d or melte d high volt age harn ess,

p oor soldering, et c.). To maint ain the p rope r min imu m level of

sof t X-Ray em ission, c omp on en ts in th e high voltag e cir cuitr y

includ ing t he pict ure tu be must b e t he e xact rep laceme nts or

alte rnat ives ap prove d b y th e ma nuf act urer of th e c omplet e

prod uct.

7. Do not c hec k high volt ag e b y dr awing an arc. Use a high volt ag e

meter or a hig h v oltag e prob e wit h a V TVM. Discharge th e

picture tube before attempting meter connection, by connecting

a clip le ad to th e grou nd f rame a nd c onn ectin g th e oth er end of

the lead through a 10kΩ 2W resisto r to the an od e b utt on .

8. W hen se rvice is requ ir e d, ob serve th e original lea d dr ess. E xtra

prec aut ion sh ou ld b e g ive n t o assure correct lead dress in th e

high voltag e circuit a rea. W here a s hort circuit h as occu rre d,

th ose co mp on ent s tha t indica te evide nce of ove rhea ting should

b e re placed. A lwa ys u se th e manuf act urer's r ep lacem en t

9. Isolation Check

(Safety for Electrical Shock Hazard)

Af ter re-ass emblin g th e p rodu ct, always perf orm an isolat ion

ch eck on the expo sed me tal p ar ts of t he cabin et (a nte nn a

ter m inals, vid eo /au dio inpu t and ou tpu t t er minals, Con trol kn obs,

metal cabin et, screwhead s, ea rph one jack, contr ol shaf ts, etc.)

to be su re th e p rodu ct is s af e t o o pe r ate with ou t d an ger of

elect rical shoc k.

(1) Dielectric Strength Test

The iso lation be tween the A C prima ry circu it an d all me tal par ts

exp ose d t o th e us er, p ar ticularly an y e xp os ed met al p art h aving a

retu rn p ath to t he chass is should withs tan d a volt age of 3 000 V

AC (r.m.s.) for a period of one second.

(. . . . W it hstan d a vo lt ag e of 1 10 0V A C (r.m. s.) t o an ap plianc e

rate d up to 12 0V , an d 3 00 0V AC (r.m. s.) to an ap pliance rat ed

200V or more, for a period of one second.)

This method of test requires a test equipment not generally found

in t he servic e trad e.

(2) Leakage Current Check

Plug th e A C lin e c ord d ir ect ly in to th e A C ou tlet (d o n ot use a lin e

isolatio n tr ansf ormer du ring this ch eck.). Usin g a " Lea kag e

Current Teste r", me asure th e lea kag e cu rre nt f rom each exposed

metal p art of the ca bine t, p art icu larly any expos ed me tal p art

h aving a re turn pa th to t he ch assis , t o a kn own go od ea rt h

grou nd (water pipe, e tc.). An y leakage cur r en t must n ot e xceed

0.5mA AC (r.m.s.).

Howeve r, in trop ic al area, th is mu st no t exce ed 0.2 mA AC

(r.m.s.).

"

""

" Alternate Che ck Method

Plug th e A C lin e c ord d ir ect ly in to th e A C ou tlet (d o n ot use a lin e

isolatio n tr an sformer during t his check.) . Use an AC vo lt me ter

h aving 100 0 oh ms pe r volt or more sens it ivity in th e fo llowing

mann er . Con nec t a 1 50 0Ω 10W res ist or par a lle led b y a 0.1 5µF

AC-type c apa cit or bet we en an exposed met al part a nd a kno wn

across th e r es ist or with th e AC voltmeter . M ove th e resistor

con nec tion to e ach exp osed metal part, p art icularly a ny exposed

metal p art havin g a retu rn pat h to t he chassis, an d measu r e th e

AC voltag e ac ross the res ist or . No w, reverse th e plu g in th e AC

ou tlet and re pe at eac h m ea surement. An y volt ag e me asured

must not exc eed 0.75V AC (r.m. s.). This c orre sponds to 0.5mA

AC (r.m.s.).

However, in tropical area, this must n ot exce ed 0.3V AC ( r.m.s.).

This corresponds to 0.2mA AC (r.m.s.).
