SECTION 1

PRECAUTION

1.1 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 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, 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.

(5) 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.

(6) 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 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 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 1000Ω 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.).

TROUBLESHOOTING

5.1 SELF CHECK FEATURE

5.1.1 OUTLINE

This unit comes with the "Self check" 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 I2C bus and

the various control lines connected to the main microcomputer.

5.1.2 HOW TO ENTER THE SELF CHECK MODE

Before entering the Self check 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 check Display mode.

(1) Set to "0 minutes" using the [SLEEP TIMER] key.

(2) While "0 minutes" is displayed, press the [VIDEO STATUS]

key and [DISPLAY] key simultaneously, then enter the

service mode.

(3) Press the [2] key (SELF CHECK) before the service mode

screen disappears.

(4) Press the [SLEEP TIMER] key to enter Page 2 of the SELF

CHECK MODE.

• When the [RETURN+] key pressed, the first page

change screen.

NOTE:

When a number key other than the [2] key is pressed in

the SERVICE MENU SCREEN, the other relevant

screen may be displayed.

This is not used in the SELF CHECK. Press the [MENU]

key to return to the SERVICE MENU SCREEN.

5.1.3 HOW TO EXIT THE SELF CHECK MODE

TO SAVE FAILURE HISTORY:

Turn off the power by unplugging the AC power cord plug when

in the Self check 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 check 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 CHECK

FEATURE

In addition to circuit failures (abnormal operation), the following

cases may also be diagnosed 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 I2C 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 check 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.
