SECTION 1
PRECAUTION
1.1SAFETY 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 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) Use isolation transformer when hot chassis.
The chassis and any sub-chassis contained in some products are
connected to one side of the AC power line. An isolation
transformer of adequate capacity should be inserted between the
product and the AC power supply point while performing any
service on some products when the HOT chassis is exposed.
(5) Don't short between the LIVE side ground and ISOLATED (NEU-
TRAL) 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, 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 the LIVE side
GND and ISOLATED (NEUTRAL) side GND or EARTH side GND at
the same time with a measuring apparatus (oscilloscope etc.). If
above note will not be kept, a fuse or any parts will be broken.
(6) If any repair has been made to the chassis, it is recommended that
the B1 setting should be checked or adjusted (See B1 POWER
SUPPLY check).
(7) 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 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.
(8) 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 10k
(9) 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.
Ω 2W resistor to the anode button.
(10) 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.
a) 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 1100V AC
(r.m.s.) for a period of one second.
(. . . . Withstand a voltage of 1100V AC (r.m.s.) to an appliance rat-
ed 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 service trade.
b) Leakage Current Check
Plug the AC line cord 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 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
following manner. Connect a 1500
a 0.15
µF AC-type capacitor between an exposed metal part
Ω per volt or more sensitivity in the
Ω 10W resistor paralleled by
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.).

Whenever degaussing works are required due to
distorted images and colors caused by the replacement
of the CRT or other external magnetic forces, self-
CRT
degaussing (internal degaussing) should be carried out
without fail instead of degaussing the monitor from the
outside.
Because of the characteristics of the CRT used in this
monitor , the distorted images and colors may worsen if
degaussing the monitor from the outside has been
performed.
Even if external degaussing works have been carried out,
self-degaussing should be performed by turning the
power on the monitor.
When you want to perform self-degaussing of the monitor

TROUBLESHOOTING
5.1SELF-DIAGNOSIS FEATURE
5.1.1 OUTLINE
This unit comes with the "Self-diagnosis" feature, which checks
the operational state of the circuit and displays/saves it during
failure.Diagnosis is performed when power is turned on, and
information input to the main microcomputer is monitored at all
time.Diagnosis is displayed in 2 ways via screen display and LED
flashes. Failure detection is based on input state of I
the various control lines connected to the main microcomputer.
5.1.2 HOW TO ENTER THE SELF-DIAGNOSIS DISPLAY MODE
Before entering the Self-diagnosis Display mode, confirm that
the setting of TV / CATV SW of the REMOTE CONTROL UNIT
is at the "TV" side and the setting of VCR / DVD SW is at the
"VCR" side. If the switches have not been properly set, you
cannot enter the Self-diagnosis Display mode.
(1) Press the [SLEEP TIMER] key and set it to 30 minutes.
(2) Press the [VIDEO STATUS] key and [DISPLY] key
simultaneously, then enter the TEST MODE.
(3) Press the [4] key (Self-diagnosis Display mode) before the
service mode screen disappears.
5.1.3 HOW TO EXIT THE SELF-DIAGNOSIS DISPLAY MODE
To Save Failure History:
Turn off the power by unplugging the AC power cord plug when
in the self-diagnosis display mode.
To Clear (Reset) Failure History:
Turn off the power by pressing the [POWER] key on the remote
control unit when in the self-diagnosis display mode.

5.1.4 FAILURE HISTORY
Failure history can be counted up to 9 times for each item.When
the number exceeds 9, display will remain as 9. Failure history
will be stored in the memory unless it has been deleted.
NOTE:
Only SYNC (with/without sync signals) will be neither counted
nor stored.
5.1.5 POINTS TO NOTE WHEN USING THE SELF-DIAGNOSIS
FEATURE
In addition to circuit failures (abnormal operation), the following
cases may also be iagnosed as "Abnormal" and displayed and
counted as "NG".
(1) Temporary defective transmissions across circuits due to
pulse interruptions
(2) Misalignment in the on/off timing of power for I
2
C bus
(VCC) when turning on/off the main power.
Diagnosis may be impeded if a large number of items are
displayed as "NG". As such, start self-diagnosis check only after
3 seconds in the case of receivers and 5 seconds in the case of
panels upon turning on the power. If recurrences are expected,
ensure to clear (reset) the failure history and record the new
diagnosis reults.
