1. SAFETY PRECAUTIONS

1. The design of this product contains special hardware, many
circuits and components especially 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
manufacturer’s warranty and will further relieve the
manufacturer of responsibility for personal injury or property
damage resulting therefrom.

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 which have these special safety
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 use of a substitute replacement which
does not have the same safety characteristics as the
recommended replacement part shown in the parts list of
Service manual may cause shock, fire, or other hazards

4. Don’ t short 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 difference of the GND is shown by the LIVE: ( )
side GND, 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).

6. The high voltage applied to the picture tube must conform to
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 severe arcing 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, 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 lead to the ground frame and connecting 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
precaution should be given to assure correct lead dress in the
high voltage circuit area. Where a short circuit has occurred,

those components that indicate evidence of overheating should
be replaced. Always use the manufacturer’s replacement
components.

9. Isolation Check
(Safety for Electrical Shock Hazard)
After re-assembling 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, screw heads, earphone jack, control shafts, etc.)
to be sure the product is safe to operate without danger of
electrical shock.

10. The surface of the TV screen is coated with a thin film which can
easily be damaged. Be very careful with it when handle the TV.
Should the TV screen become soiled, wipe it with a soft dry
cloth. Never rub it forcefully. Never use any cleaner or detergent
on it.

(1) Dielectric Strength Test

The isolation between the AC primary circuit and all metal parts
exposed to the user, particularly any exposed metal part having
a return path to the chassis should withstand 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 appliance
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 test equipment not generally found
in the service trade.

(2) Leakage Current Check

Plug the AC line cord directly into the AC outlet (do not use line
isolation transformers 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.). Any leakage current must 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 line cord 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 sensitivity in the
following manner. Connect a 1500Ω 10W resistor paralleled by
a 0.15μF AC-type capacitor between an exposed metal part and
a known good earth ground (water pipe, etc.). Measure the AC
voltage across the resistor with the AC voltmeter. Move the
resistor connection to each exposed metal part, particularly any
exposed metal part having a return path to the chassis, and
measure the AC voltage across the resistor. Now, reverse 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, in tropical area, this must not exceed 0.3V AC
(r.m.s.).
This corresponds to 0.2mA AC (r.m.s.)

一、Enter Factory Menu

1） Entrance of factory controller: Use factory key to enter/switch/exit factory mode. Entrance of common

controller: When main menu appears, enter code 6483, which is equivalent to factory key.

2） Specification: Factory mode includes three kinds: FACTORY: for factory aging; B/W BALANCE：for

adjustment of black and white balance; ADJUST：for all adjustments of factory.

Pressing factory key (or pressing 6483 when main menu appears) will display the following:

三、Explanation of Special Function

1． Enter factory LOG set: press “LOGO” key will directly enter into adjusting mode; or in “AV” indication for

common controller in AV state, successively input 6483 will also enter into adjusting mode.

st

2、Setting of factory LOGO: There are two lines for factory LOGO, the 1

nd

defined by customer; the 2

of which is for customer to define (it is available for customer to set not more

of which is “Double Happiness” or

than 13 characters). And customer may set switch, font, color, up/down position and left/right position. If

“LOGO” in the menu is set in “ON” position, the screen will show the equivalent “LOGO” when there is on

signal in POWER-ON state.

• The setting menu of factory logo is displayed on two screens, which are available to adjust the 1

nd

line and 2

line of the LOGO separately. After entering the setting menu, press POS+/POS to

st

6

choose different options. Yellow block will appear when displaying item is selected, and then use

VOL+/VOL- key to adjust the selected item.

st

• Adjustment of the selected item: use RECALL key to select the shown item in 1

or 2nd line, when

yellow block indicates the current selectable character, use VOL+/VOL key to adjust the selected

character.

• It is available to use “0” key to eliminate the current set character.

• On setting menu, press DISPLAY key to indicate adjustment effect, and re-press DISPLAY key to

return LOGO set menu. Factory LOGO set is in “to gain what is seen”; and the other items, color, font,

position in the displaying lines are completely the same in normal display. So, while adjusting, it is

available to see the adjusted effect.

• Setting of items in two lines. Do not set overlapping (even if one line is set in OFF position) so as to

prevent abnormal display.

• When adjusting V POS, the menu probably may flash, but this will not affect LOGO display when TV

set is turned on.

3．Note: After setting, change screen protection mode through factory setting item. Please see Page

SERVCJ3 for details.

6-2、Realization of factory automatic adjustment

Note: There is no any effect for any key in BUS OPEN mode.

Pin 13 of CPU is the automatic adjustment ENABLE terminal; high level should be kept in normal

working state. When the terminal is connected to low level, CPU will transfer the control of BUS LINE to

automatic equipment (automatically enter into “BUS OPEN” mode); and the automatic equipment will send

data to decoding CMOS chip through BUS LINE to implement adjustment. Then it will save the adjusted

data in the address of equivalent EEPROM and recover the high level in ENABLE terminal. CPU returns to

normal working state. The concerned data of automatic decoding piece and EEPROM address are as

follows:

Address of EEPROM: written address: A0H read address: A1H

Address of decoding piece: written address: BAH read address: BBH
