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

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

or higher, sensitivity or measure the AC voltage drop

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

2. Disconnect AC power before servicing.

» 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

BEFORE RETURNING THE RECEIVER
(Fire & Shock Hazard)

indicates a potential shock hazard which must be
corrected before returning the monitor to the owner .

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

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”

Procedure for upgrading the software (AVC System)

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

NORMAL position to the WRITE position by inserting a needle-like insulator 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.

(2)Connect the PC having the program installed, to the AVC System using the cross cable for the RS-232C port

(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 LCD Display Unit have been connected.
(5)Run “vup.bat (tentaive name)” at the MS-DOS prompt. The software will be upgraded.
(6)Load the file “civc_XXXXa.bhxmain.bhxosd.bhxt (tentaive name)”. It will take approximately a few 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 LCD Display Unit and the AVC System and then return the slide

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

Procedure for adjusting each part of AVC System and LCD Display

» 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 is replaced, perform the following steps.

» Any parameter that has been changed within the process adjustment is stored on the memory . If any readjustment

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

» Use a stable AC power source.
» 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.

DESCRIPTION OF SCHEMATIC DIAGRAM

VOL TAGE MEASUREMENT CONDITION:

1. When the exclusive-use AC adapter is used, the colour
bar signal of colour 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 colour
density, lightness and colour hue are set to the center
position, and the signal of colour 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

CAPACITOR

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
