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 150010W 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 10k2W 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.

REMOVING THE CRT  
Replacement of the CRT should be performed by 2 or more  
pers ons.  
CRT CHANGE TABLE  
After removing the cover, chassis etc.,  
1. Putting the CRT c hange table on soft cloth, the CRT change table  
should also be c overed with s uch soft cloth (shown in Fig. 3).  
2. While keeping the s urfac e of CRT down, mount the TV s et on the  
CRT change table balanced will as shown in Fig.4.  
3. Remove 4 sc rews marked by arrows with a box type screw driver  
as s hown in Fig. 4.  
APPROX.  
35cm  
CLOTH  
Sinc e the cabinet will drop when screws have been removed, be  
sure to support the cabinet with hands.  
4. After 4 screws have been removed, put the cabinet slowly on  
cloth (At this time, be carefully so as not to damage the front  
surfac e of the c abinet) shown in Fig. 5.  
Fig. 3  
Fig. 4  
Fig. 5  
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.

COATING OF SILICON GREASE FOR ELECTRICAL  
INSULATION ON THE CRT ANODE CAP SECTION.  
Subsequent to replacement of the CRT and HV transformer or  
repair of the anode cap, etc. by dismounting them, be sure to  
coat silic on greas e for electrical insulation as shown in Fig.6.  
Wipe around the anode button with clean and dry cloth. (Fig.6)  
Coat silicon grease on the section around the anode button. At  
this time, take care so that any silicon greases dose not stick to
