IMPORTANT SERVICE SAFETY PRECAUTION

Ë

Service work should be perfomed only by qualified ser vice 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 A C 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 necessar y, 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

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 A C 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 , w attage , 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”

ADJUSTMENT PROCEDURES (AVC SYSTEM)

Preparation for adjustment

1. The product has been adjusted and optimized in the factory. If the product needs to be readjusted for some
reason, e.g., after parts replacement, follow the instructions shown below.

2. Control parameter values set in the in-process adjustment mode has been stored in the corresponding registers.
When the product is readjusted, the contents of the registers are changed. Bef ore readjustment, f actory settings
should be noted in case the contents of registers require to be restored.

3. Use a stabilized AC power supply.

4. To rewrite a program, you should note the items you want to change and initialize EEPROM, and then rewrite
the changes into EEPROM.

How to enter the in-process adjustment mode

CAUTION: Exercise great care to hide the procedure in entering the in-process adjustment mode from the
customer. Inadvertent setting changes in this mode may cause a fatal error resulting in a program being
unrecoverable.

1. Entering the in-process adjustment mode:
Connect the system cable between the display and AVC system.
Turn on the main power while holding down the "Input" button and the "Volume (down)" button simultaneously.
The system will be activated.
~If you see multiple lines of blue characters on the display, you are in the in-process adjustment mode. If not

(the normal activation screen opens), retry.

2. Accessing the inspection process mode:
After activation of the system, make adjustments according to the instructions indicated on the process adjustment
OSD menu screen.
Move to the General Process Adjustment (AVC System Section Process).

3. Restoring factory settings:
When the "INDUSTRY INIT" button is selected after activation of the system, factory channel setting remains
unchanged after the system exits from the in-process adjustment mode.
Changes made by the user will default to factory settings. Note that channel setting is also initialized.

4. Exiting from the in-process adjustment mode:
Unplug the power cable while the system is in the in-process adjustment mode to exit from the mode.
Take care not to press the "Power" button on the remote controller or the AVC system after using factory
settings to run the system.

5. OSD menu screen and menu items during manual adjustment:

~The layout and men u items of the OSD menu screen ma y some what vary depending on the program versions .
~Just rewriting a program does not cause settings to be "initial values". (Preparation for adjustment)

DESCRIPTION OF SCHEMATIC DIAGRAM

VOLTAGE 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,
wavefor ms 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
