SAFETY PRECAUTIONS
V-29RS
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.
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
manuf act urer's warr an t y and wil l fur t h er reli ev e the manufacturer
of responsi bility f or person al injury or pr operty dam age res ulting
therefrom.
3. Many electrical and mechanical parts in the products have
special safety-related characteristics. These characteristics are
often not evident f rom visual i nspection nor can t he protect ion
afford ed by them n ecess arily be obt ained by using rep lacem ent
compon ents rated f or higher voltag e, watt ag e, etc. R epl acem ent
parts which have these special safety characteristics are
identified in the parts list of Service manual.
compon ents hav in g su ch feat ures are id entif ied by s hadin g

have the same safety characteristics as the recommended
replac ement part shown i n the p arts list of S ervic e manu al may
cause shock, fire, or other hazards.
) on the parts list in Service
!!!!
Electrical
4.
Don't short b etween the LIV E side groun d and ISOLATED
(NEUTRAL) side ground or EARTH side ground when
repairing.
Some model's power circuit is partly different in the GND. The
difference of the GND is show n b y th e 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 meas ure with a measuri ng apparatus (osc illoscope etc .)
the LIVE side GND and ISOLATED(NEUTRAL) side GND or
EARTH side GND at the same time.
If above not e wi ll n ot be kept, a fus e or an y part s will be broken.
5. 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).
6. The hig h voltage app lied t o the picture t ube must c onform wit h
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 conditions s hould b e kept to a mi nimum, or sh ould be
prevented. If severe arcing occurs, remove the AC power
immediately and determine the cause by visual inspection
(incorrect install ation, cracked or melted high voltag e harness,
poor solderi ng, etc.). To maintain the pr oper 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 l ead to th e g roun d fr am e and c on necti ng t h e oth er end of
the lead through a 10k! 2W resistor t o the an ode button.
8. W hen servic e is requir ed, obser ve the origin al lead dress . Extr a
precaut ion shou ld be gi ven to assure c orrect l ead dr ess in t he
high voltage circuit area. Where a short circuit has occurred,
those comp onents that in dicat e evidenc e of over heating should
be replaced. Always use the manufacturer's replacement
components.
9.
Isolation Check
(Saf ety for Electrical Shock Hazard)
After re-assembling the product, always perform an isolation
check on the exposed metal parts of the cabinet (antenna
termin als , vid eo/ au dio input an d output term in als , C on trol knobs,
metal cabinet, screw"heads, ear phone jac k, control shafts, etc.)
to be sure the product is safe to operate without danger of
electrical shock.
(1)
Dielectric Stren gth Test
The isol ation b etween th e AC pr imar y circuit and all metal parts
expos ed t o th e user, p ar tic u larly any expo sed metal part h avi ng a
return p ath to the chassis should withst and a voltage of 3000V
AC (r.m.s .) for a period of one secon d.
(. . . . W ithstand a voltag e of 1100 V AC ( r.m.s.) to an applianc e
rated up t o 120V, and 3000 V AC (r. m.s.) t o an appl iance r ated
200V or mor e, f or a peri od of on e s ec on d.)
This method of test requires a test equipment not generally found
in the service trade.
(2)
Leak age Current Check
Plug the AC lin e c or d dir ec t l y int o t he AC outlet ( d o 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. ). An y leak age c urr ent mus t 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 lin e c or d dir ec t l y int o t he AC outlet ( d o not use a line
isolati on transform er during t his check. ). Use an AC voltmet er
having 1000 ohms per volt or more sensitivity in the following
manner. Connect a 1 500! 10W resistor paralleled by a 0.15#F
AC-typ e capacitor betw een an expos ed metal part and a know n
good earth ground (water pipe, etc.). Measure the AC voltage
across the resistor with the AC voltmeter. Move the resistor
connect ion t o each exp os ed met al p art, part icul arl y any exp osed
metal part h avin g a return p ath to th e chassis , and meas ure th e
AC voltag e across the res istor. N ow, re vers e 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 , i n t ropical area, this must n ot exceed 0.3 V AC (r.m.s. ).
This corresponds to 0.2mA AC (r.m.s.).

1.
There are 2 ways of adjusting this TV: One is with the
REMOTE CONTRO L UNIT and t he oth er is t he conv ention al
method using adjustment pa rts and components.
2.
The adjustment with the REMOTE CONTROL UNIT is made
on the basis of the init ial sett ing valu es . The set tin g val ue s
which adjust the screen t o it s o pt i mum cond ition may differ
from the initial setting values.
3. Make sure that connection is correctly made to AC power
source.
4. Turn on the p ower of the set and eq uipment before use, and
start the adjustment procedures after waiting at least 30 minutes.
5. Unl ess other wis e specifi ed, prep are the mos t suitab le rec eption
or input signal for adjustment.
6. Never touc h any adjus tm ent par ts, whic h are not spec ifi ed in the
