HV-29LPZ
SAFETY PRECAUTIONS
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 identic al to thos e used in the original
circuits. Service should be performed by qualified pers onnel
only.
9. Isolation Check
(Safety for Electrical Shock Hazard)
After re-ass embling 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 cabinet, screwheads, earphone jack, control shafts, etc.)
to be sure the product is s afe to operate without danger of
electrical shoc k.
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 responsibility for personal injury or property damage resulting
therefrom.
(1) Dielectric Strength Test
The isolation between the AC primary circuit and all metal parts
exposed to the us er, particularly any expos ed metal part having a
return path to the chass is should withs tand a voltage of 3000V
AC (r.m.s.) for a period of one second.
(. . . . Withstand a voltage of 1100V AC (r.m. s.) to an applianc e
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 found
in the servic e trade.
3. Many electrical 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 necessarily be obtained by using replacement
components rated for higher voltage, wattage, etc. Replacement
parts whic h have these special s afety 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
replac ement part shown in the parts list of Service manual may
cause shock, fire, or other hazards.
(2) Leakage Current Check
Plug the AC line c ord 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 expos ed metal part
having a return path to the chassis , to a known good earth
ground (water pipe, etc.). Any leakage current must not exceed
0.5mA AC (r.m.s.).
However, in tropic al area, this must not exceed 0.2mA AC
(r.m.s.).
4. Don't short between the LIVE side ground and ISOLATED
(NEUTRAL) side ground or EARTH side ground when
repairing.
" Alternate Check Method
Plug the AC line c ord 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 sens itivity in the following
manner. Connec t a 1500Ω 10W res istor paralleled by a 0.15µF
AC-type c apacitor between an exposed metal part and a known
good earth ground (water pipe, etc.). Meas ure the AC voltage
across the res istor with the AC voltmeter. Move the resistor
connec tion to each exposed metal part, particularly any exposed
metal part having a return path to the chassis, and measure the
AC voltage ac ross the res istor. Now, reverse the plug in the AC
outlet and repeat eac h measurement. Any voltage measured
must not exceed 0.75V AC (r.m.s.). This corresponds to 0.5mA
AC (r.m.s.).
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 apparatus (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 kept, a fuse or any parts 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).
However, in tropical area, this must not exceed 0.3V AC ( r.m.s.).
This corresponds to 0.2mA AC (r.m.s.).
6. 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 s evere arc ing occurs, remove the AC power
immediately and determine the cause by visual inspection
(incorrect installation, cracked or melted high voltage harness,
poor soldering, etc.). To maintain the proper minimum level of
soft X-Ray emission, c omponents in the high voltage circuitry
including the picture tube must be the exact replacements or
alternatives approved by the manufacturer of the c omplete
product.

7. Do not c hec k high voltage by drawing an arc. Use a high voltage
meter or a high v oltage probe with a VTVM. Discharge the
picture tube before attempting meter connection, by connecting
a clip lead to the ground frame and c onnecting the other end of
the lead through a 10kΩ 2W resistor to the anode button.
8. When service is required, observe the original lead dress. Extra
prec aution should be given to assure correct lead dress in the
high voltage circuit area. W here a s hort circuit has occurred,
those components that indicate evidence of overheating should
be replaced. Always use the manufacturer's replacement
components.

The CRT should be ass embled according to the opposite
sequence of its dismounting steps.
∗
The CRT change table should preferably be smaller that the CRT
surfac e, and its height be about 35c m. (Fig.3)
∗ About CRT Spacer (Fig.4)
An appropriate CRT spacer should be us ed in the corresponding
CRT in acc ordance with the type of the CRT.
When a CRT is replaced, special attention should be paid to this
matter.

SERVICE ADJUSTMENTS
BEFORE STARTING SERVICE ADJUSTMENT
1. There ar e 2 ways of adjusting this TV: One is with the
REMOTE CONTROL UNIT and the other is the conventional
method using adjustment parts and components.
2. The setting (adjustment) using the REMOTE CONTROL
UNIT is made on the basis of th e initial setting values. The
setting values which adjust the screen to the optimum
condition can be different from the initial setting values.
3. Make s ure that connection is c orrectly made to AC power
source.
7. Preparation for adjustment (pres etting):
Unless otherwis e specified in the adjustment items, preset the
following functions with the REMOTE CONTROL UNIT:
