STANDARD CIRCUIT DIAGRAM

NOTE ON USING CIRCUIT DIAGRAMS

1.SAFETY

The components identified by the symbol and shading are
critical for safety. For continued safety replace safety critical
components only with manufactures recommended parts.

2.SPECIFIED VOLTAGE AND WAVEFORM VALUES

The voltage and waveform values have been measured under the
following condition s.

(1)Input signal : Colour bar signal

(2)Setting positions of
each knob/button and
variable resistor

(3)Internal resistance of tester

:DC 20k

/V

(4)Oscilloscope sweeping time

:H

20µS/div

:V

5mS/div

:Others

Sweeping time is
specified

(5)Voltage values

:All DC voltage values

Since the voltage values of signal circuit vary to some extent
according to adjustments, use them as reference values.

5.NOT E FOR REPAIR ING SERVI CE

This mod el's power cir cuit is pa rtly diffe rent in th e GND. The
difference of the GND is shown by the LIVE : ( ) side GND and the
ISOLATED(NEUTRAL) : ( ) side GND.Therefore, care must be
taken for the following points.

(1)Do not touch the LIVE side GND or the LIVE side GND and the
ISOLATED(NEUTRAL) side GND simultaneously. If the above
caution is not respected, an electric shock may be caused.
Therefore, make sure that the power cord is surely removed from
the receptacle when, for example, the chassis is pulled out.

(2)Do not short between the LIVE side GND and ISOLATED(NEUTRAL)
side GND or never measure with a measuring apparatus measure
with a measuring apparatus ( oscilloscope, etc.) the LIVE side GND
and ISOLATED(NEUTRAL) side GND at the same time.
If the above precaution is not respected , a fuse or any parts will be broken.

Since the circuit diagram is a standard one, the ci rcuit and
circuit constants may be subject to change for improvement
without any not ice.

NOTE
Due improvement in performance, some part numbers show
in th e ci rcui t diag ram may not agre e wi th th ose i ndica ted i n
the part list.
When ordering parts, pl ease use t he numbers t hat appear
in the Par ts List.

SAFETY PRECAUTIONS

V-T292

1. T he desi gn of this product con ta ins sp eci al hardware, many
circuits and components spe cially for safety purposes. For
con tinu ed pr ot ection, n o changes sh ou ld be made to the orig inal
desi gn un less auth orized in writi n g by th e manu fact ur er.

Replacement p ar ts must b e id ent ic al to thos e used in th e original
ci rcu it s. S ervi ce sho uld b e performed by qu al if ied pers on nel
only.

2. Alte rati on s of t he desig n or cir cuitry of t he prod ucts sh ould not be
made. Any design alterations or additions will void the
manufact urer 's warr a nt y and w ill f urth er r elieve t he ma nu factu r er
of resp onsibility for perso na l injur y or p r op er ty damage result ing
th erefr om.

3. M an y electr ical an d m echanic a l parts i n the products ha ve
special safety-related characteristics. T hese characteristics are
oft en no t evi den t from visua l insp ecti on n or can t he pr o tect io n
aff or de d by th em necessaril y be ob tained by using rep lacement
com po ne nts rated for hig he r voltage, watt ag e, etc. Rep l acement
parts wh ic h have th ese speci al s afet y ch aract erist ics are

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

components having su ch features are identified by shading
on the sche mat ic s an d b y (!!!! ) on the parts list in Service
manual. The us e of a sub sti tu te replacement which do es not

have the sam e saf ety ch ar act er ist ics as t he r ecommen de d
replac ement par t shown in the parts list of S ervice m an ual may

cause shock, fire, or other hazards.

4. Do n't short between the LIVE s ide ground and ISOLATE D

(NEUTRAL) s ide 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 sho wn by the LIV E : (") side GND, the
ISO LATE D(NEUTRAL) : (#) side G ND and EART H : ($) side
GND. Do n't sh ort bet ween th e LIVE sid e GND an d

ISO LATE D(NEUTRAL) side GND or EARTH side GND an d
never m ea sure wit h a mea suring apparatus (oscil loscope etc.)
th e LI VE sid e GN D and IS OLATED(NE UTR AL ) side G ND or
EARTH sid e GND at the same tim e.
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 shou ld b e ch ecke d or adjusted (See
ADJUSTMENT OF B 1 POWE R SUPPL Y).

6. The high vol ta ge applie d t o the pictu re tube must con for m with
th at speci fi ed i n S er vice manual. E xcessive h i gh voltage ca n

cau se an incr e ase in X-Ray emissi on , ar cing and possible
component damage, therefore operation under excessive high
voltage conditions should be kept to a minimum, or should be
preve nt ed. If s evere arc ing occurs, remove t he AC pow er

9. Isol ation Check

(Safety for Electrical Shock Hazard)

Af ter re- ass emb ling the p rodu ct, alw ays perf orm an isolat ion
ch eck on the expo sed metal parts of t he cabinet (ante nn a

termina ls, video/au dio input and outpu t termin als, Con trol knobs,
metal cab ine t, screw h eads , ear p ho ne jac k, cont rol sh aft s, etc .)
to be sure th e p r odu ct is s af e t o o perate without d an ger of
elect rical shoc k.

(1) Dielectric Strength Test

The isolation between the AC prima ry ci rcu i t an d all metal p arts
exp osed t o th e user, p articul ar ly an y expos ed metal part havi ng a
return path to the chass is sho ul d withs tand a volt age of 3 000 V
AC (r.m.s.) for a period of one second.

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

rated up to 12 0V, an d 3 00 0V AC ( r .m. s.) to an applian ce rat ed
200V or more, for a period of one second.)
This method of test requires a test equipment not generally found
in the ser vice trad e.

(2) Leakage Current Check

Plug th e A C line c ord direct ly in to the AC outlet (do not use a lin e
isolation transf ormer dur in g thi s ch eck.) . Usi n g a "Leakag e

Curr ent T ester", measure th e leakag e current f rom each exp osed
metal part of the ca bine t, particu larly any e xpos ed metal part
havi ng a return path to the ch assis , t o a known good earth
ground (wa ter pip e, etc.). An y leakage curr en t mus t n ot exceed

0.5mA AC (r.m.s.).
However, in tropic al area, th is must no t exceed 0.2 mA AC
(r.m.s.).

"""" Alternate Che ck M et hod

Plug th e A C line c ord direct ly in to the AC outlet (do not use a lin e
isolation tran sformer dur i ng t his check.) . Use an AC v o lt meter

havi ng 1 00 0 oh ms per volt or more sens itivity in th e following
manner. Connec t a 1500Ω 10W res ist or para lle led by a 0 .15µF

AC-type capacit or bet ween an expo sed met al part and a known
good earth gro un d ( water pipe, etc.). Meas ure the A C voltag e
acr oss th e res ist or with th e AC vo l tm eter . M ove th e resi stor
con nec ti on to e ach exp ose d metal part, part i cular l y a ny exp osed

metal part havi n g a r etu rn pat h to t he chassis, an d m easure the
AC voltag e ac ross the res ist or. N o w , re verse th e pl u g in th e AC
outlet and re pe at eac h measur emen t. Any volt age measu re d
must not exc eed 0 .7 5V AC (r.m.s.). This c orresponds to 0.5mA
AC (r.m.s.).

Howeve r, in tropical area, this must n ot exce ed 0 .3V AC ( r.m.s.).
This corresponds to 0.2mA AC (r.m.s.).
