IMPORTANT SERVICE SAFETY PRECAUTION

Ë

Service work should be perfomed only by qualified service technicians who are thor­oughly familiar with all safety checks and the servicing guidelines which follow:

WARNING

1. For continued safety, no modification of any circuit
should be attempted.

2. Disconnect AC power before servicing.

CAUTION: FOR CONTINUED
PROTECTION AGAINST A RISK
OF FIRE REPLACE ONLY WITH
SAME TYPE FUSE. F701 (T2A,

A V

250V), F702 (T2A, 250V), F1702
(T4AL, 250V) FUSE.

BEFORE RETURNING THE RECEIVER
(Fire & Shock Hazard)

Before returning the receiver to the user, perform
the following safety checks:

1. Inspect all lead dress to make certain that leads are
not pinched, and check that hardware is not lodged
between the chassis and other metal parts in the
receiver.

2. Inspect all protective devices such as non-metallic
control knobs, insulation materials, cabinet backs,
adjustment and compartment covers or shields,
isolation resistor-capacitor networks, mechanical
insulators, etc.

3. To be sure that no shock hazard exists, check for
leakage current in the following manner.

» Plug the AC cord directly into a 110~240 volt AC outlet,

and connect the DC power cable into the receiver's
DC jack. (Do not use an isolation transformer for this
test).

» Using two clip leads, connect a 1.5k ohm, 10 watt

resistor paralleled by a 0.15µF capacitor in series
with all exposed metal cabinet parts and a known
earth ground, such as electrical conduit or electrical
ground connected to an earth ground.

» Use an AC voltmeter having with 5000 ohm per volt,

or higher, sensitivity or measure the AC voltage drop
across the resisor.

» Connect the resistor connection to all exposed metal

parts having a return to the chassis (antenna, metal
cabinet, screw heads, knobs and control shafts,
escutcheon, etc.) and measure the AC voltage drop
across the resistor.
All checks must be repeated with the AC cord plug
connection reversed. (If necessary, a nonpolarized
adaptor plug must be used only for the purpose of
completing these checks.)
Any reading of 35V peak (this corresponds to 0.7
milliamp. peak AC.) or more is excessive and
indicates a potential shock hazard which must be
corrected before returning the monitor to the owner.

SAFETY NOTICE

Many electrical and mechanical parts in Plasma Display
television have special safety-related characteristics.
These characteristics are often not evident from visual
inspection, nor can protection afforded by them be
necessarily increased by using replacement components
rated for higher voltage, wattage, etc.
Replacement parts which have these special safety
characteristics are identified in this manual; electrical

and shaded areas in the

Schematic Diagrams

For continued protection, replacement parts must be
identical to those used in the original circuit.
The use of a substitute replacement parts which do not
have the same safety characteristics as the factory
recommended replacement parts shown in this service
manual, may create shock, fire or other hazards.

components having such features are identified by “ å”

PRECAUTIONS A PRENDRE LORS DE LA REPARATION

Ë

Ne peut effectuer la réparation qu' un technicien spécialisé qui s'est parfaitement
accoutumé à toute vérification de sécurité et aux conseils suivants.

AVERTISSEMENT

1. N'entreprendre aucune modification de tout circuit.
C'est dangereux.

2. Débrancher le récepteur avant toute réparation.

PRECAUTION: POUR LA PROTECTION
CONTINUE CONTRE LES RISQUES
D'INCENDIE, REMPLACER LE FUSIBLE
P AR UN FUSIBLE DE MEME TYPE F701

A V

(T2A, 250V), F702 (T2A, 250V), F1702
(T4AL, 250V).

VERIFICA TIONS CONTRE L'INCEN-DIE ET
LE CHOC ELECTRIQUE

Avant de rendre le récepteur à l'utilisateur, effectuer
les vérifications suivantes.

1. Inspecter tous les faisceaux de câbles pour s'assurer
que les fils ne soient pas pincés ou qu'un outil ne soit
pas placé entre le châssis et les autres pièces
métalliques du récepteur.

2. Inspecter tous les dispositifs de protection comme les
boutons de commande non-métalliques, les isolants,
le dos du coffret, les couvercles ou blindages de réglage
et de compartiment, les réseaux de résistance­capacité, les isolateurs mécaniques, etc.

3. S'assurer qu'il n'y ait pas de danger d'électrocution en
vérifiant la fuite de courant, de la facon suivante:

• Brancher le cordon d'alimentation directem-ent à une
prise de courant de 110-240V. (Ne pas utiliser de
transformateur d'isolation pour cet essai).

• A l'aide de deux fils à pinces, brancher une résistance
de 1.5 kΩ 10 watts en parallèle avec un condensateur
de 0,15µF en série avec toutes les pièces métalliques
exposées du coffret et une terre connue comme une
conduite électrique ou une prise de terre branchée à
la terre.

• Utiliser un voltmètre CA d'une sensibilité d'au moins
5000Ω/V pour mesurer la chute de tension en travers
de la résistance.

• Toucher avec la sonde d'essai les pièces métalliques
exposées qui présentent une voie de retour au châssis
(antenne, coffret métallique, tête des vis, arbres de
commande et des boutons, écusson, etc.) et mesurer
la chute de tension CA en-travers de la résistance.
T outes les vérifications doivent être refaites après avoir
inversé la fiche du cordon d'alimentation. (Si nécessaire,
une prise d'adpatation non polarisée peut être utilisée
dans le but de terminer ces vérifications.)
Tous les courants mesurés ne doivent pas dépasser
0,5 mA.
Dans le cas contraire, il y a une possibilité de choc
électrique qui doit être supprimée avant de rendre le
récepteur au client.

ADJUSTMENT PROCEDURES

ËË

Ë Procedure for turning ON the power

ËË

1. Connecting the system

(1)Using the system cable, interconnect the plasma display and the AVC system.
(2)Connect the plasma display to the AC power source.
(3)Connect the AVC System to the AC power source.

2. Procedure for turning ON the power

(1)Turn ON the AC power switch located on the plasma display.

The power indicator on the plasma display will start blinking in red.
(When the AC power switch on the AVC System is not ON, the power indicator on the plasma display always
blinks in red.)

(2)Turn ON the power switch located on the AVC System.

The power indicator on the AVC System will be illuminated in green. Simultaneously , the power indicator on the
plasma display will change from blinking in red to illumination in green. Now the system has started up.

(3)If the power indicators on the AVC System and on the plasma display are both illuminated in red, press the

power key located on the remote controller and the power button located on the plasma display. The power
indicators on the plasma display and on the AVC System will change from red to green. Now the system has
started up.

ËË

Ë Procedure for upgrading the AVC System software

ËË

(1)With the power being OFF, open the top cabinet of the AVC System and then set the slide switch from the

NORMAL position to the WRITE position by inserting an insulated stick into the cutout located between the
WHITE port on the rear of the shield case for the PC I/F unit and the RS-232C port. (Or the software may be
upgraded by calling the process adjustment mode and using CENTER PROG UPDATE on the process
adjustment menu screen. This is discussed later.)

(2)Connect a program-installed PC to the AVC system using the RS-232C cross cable. (For the details of the

program, see Appendix.)
(3)Open the MS-DOS window on the PC and then go to the directory in which the software is installed.
(4)Start up the system to which the AVC System and plasma display have been connected.
(5)Run “vup.bat (tentative name)” at the MS-DOS prompt. The software will be upgraded.
(6)Load the file “civic_XXXXa.bhx main.bhx osd.bhx (tentative name)”.

It will take a couple of minutes until the file has been loaded. Never turn OFF the power or operate the system

during this rewriting period.
(7)After the file has been loaded, turn OFF the plasma display and the AVC System, and then return the slide

switch in the above step (1) back from the WRITE position to the NORMAL position. Now the software has been

upgraded.

ËË

Ë Procedure for adjusting each part of the AVC System

ËË

1. The adjustments were made to the best settings at factory. If any setting deviates or if any readjustment is

regarded as necessary when any part has been replaced, perform the following steps.

2. Any parameter that has been changed in the process adjustment mode is stored on the memory. If any

readjustment is required, write down the current value before changing it.

3. Use a stable AC power source.

4. If the program is upgraded, it will take approximately 1 minute for the EEPROM to be initialized before any

video appears. Therefore, you will need to wait for this time period. Do not turn OFF the power or operate the

system during the period.

5. If the program is rewritten, preferably write down the parameters that have been changed within the process

adjustment (see “OSD menu and parameters displayed at manual adjustment”), initialize the EEPROM, and

then reenter the recorded values.

DESCRIPTION OF SCHEMATIC DIAGRAM

VOLTAGE MEASUREMENT CONDITION:

1. When the exclusive-use AC adapter is used, the color
bar signal of color bar generator for service is input to
get the normal screen. When the audio is minimized,
the voltage value is measured with the 20 kΩ/V tester.

WAVEFORM MEASUREMENT CONDITION:

1. When the exclusive-use AC adapter is used, the color
density, lightness and color hue are set to the center
position, and the signal of color bar generator for service
is observed to get waveform.

2. indicates waveform check points (See chart,
waveforms are measured from point indicated to
chassis ground.)

INDICATION OF RESISTOR & CAPACITOR:

RESISTOR

1. The unit of resistance “Ω” is omitted.
(K=kΩ=1000 Ω, M=MΩ).

2. All resistors are ± 5%, unless otherwise noted.
(J= ± 5%, F= ± 1%, D= ± 0.5%)

3. All resistors are Carbon type, unless otherwise noted.

C : Solid W : Cement

S : Oxide Film T : Special

N : Metal Coating

CAP ACITOR

1. All capacitors are mF, unless otherwise noted.
(P=pF=mmF).

2. All capacitors are Ceramic type, unless otherwise
noted.
(ML) : Mylar (TA) : Tantalum
(PF) : Polypro Film (ST) : Styrol

CAUTION:

This circuit diagram is original one, therefore there may be a
slight difference from yours.

IMPORTANT SAFETY NOTICE:

PARTS MARKED WITH “å” ( )ARE
IMPORTANT FOR MAINTAINING THE SAFETY OF
THE SET. BE SURE TO REPLACE THESE PARTS
WITH SPECIFIED ONES FOR MAINTAINING THE
SAFETY AND PERFORMANCE OF THE SET.
