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 F701 (T2A, 250V), F702 (T2A, 250V)
AND 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”

» Connect the Panel Unit to the AC power source.
» Connect the AVC System to the AC power source.

2. Procedure for turning ON the power

» Turn ON the AC power switch located on the Panel Unit.

The STANDBY/ON indicator on the Panel Unit will start blinking in red.
(When the AC POWER button on the AVC System is not ON, the STANDBY/ON indicator on the Panel Unit
always blinks in red.)

» Turn ON the POWER button located on the AVC System.

The ST ANDBY/ON indicator on the AVC System will be illuminated in green. Simultaneously , the power indicator
on the Panel Unit will change from blinking in red to illumination in green. Now the system has started up.

» If the STANDBY/ON indicator on the AVC System is illuminated in red, press the POWER button located on the

remote control unit and the MAIN POWER button located on the Panel Unit. The STANDBY/ON indicators on
the Panel Unit and the AVC System will change from red to green. Now the system has started up.

Ë

Procedure for upgrading the software

(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 Panel 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 Panel 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.

Ë

Procedure for adjusting each part of AVC System

» 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.

» If the program is rewritten, write down the parameters that have been changed within the process adjustment

(see “5”.OSD menu and parameters displayed at manual adjustment), initialize the EEPROM, and then reenter
the recorded values.

After power-on P4.0,P4.1,P4.4 work as additional address lines A17…A19.
In port mode, these port lines act as bi-directional I/O port with internal pull-up
resistors. Port pins that have ‘1’ written to them are pulled high by the internal pull-up
resistors and in that state can be used as inputs.
Port 0 is a 8-bit open drain bi-directional I/O-port. Port 0 pins that have 1 written to
them float: in this state they can be used as high impedance inputs.
Port is a 8-bit bi-directional multifunction I/O port with internal pull-up resistors. Port 1
pins that have 1 written to them are pulled high by the internal pull-up resistors and in
that state can be used as inputs.
The secondary functions of port 1 pins are:
Port bits P1.0-P1.5 contain the 6 output channels of the 8-bit pulse width modulation
unit.

Port 3 is an 8-bit bi-directional I/O port with internal pull-up resistors, Port 3 pins that
have 1 written to them are pulled high by the internal pull-up resistors and in that state
can be used as inputs,
To use the secondary functions of Port 3, the corresponding output latch must be
programmed to a one (1) for that function to operate. The secondary functions are as
follows:
» Alternate function
P3.0 : ODD/EVEN indicate output
P3.1 : external extra interrupt 0 (INTX0)/UART(TXD)
P3.2 : interrupt 0 input/timer 0 gate control input)INT0)
P3.3 : interrupt 1 input/timer 1 gate control input)INT1)
P3.4 : counter 0 input (T0)
P3.5 : counter 1 input (T1) or In master mode HS or VCS output.
P3.7 : external extra interrupt 0 (INTX1)/UART (RXD)
Port 4 is a bi-directional I/O port with internal pull-up resistors.
Port 4 pins that have 1 written to them are pulled high by the internal pull-up resistors
and in that state can be used as inputs.
Secondary functions
P4.2: RD, Read line. This signal is same as the to output of the pin RD available in
some packages.
P4.3: WR write line. This signal is same as the output of the pin WE, which is only

This pin must be pulled low to access external ROM.
Enable Emulation
Only if this pin set to zero externally, STOP and OCF are operational. ENE has an
internal pull-up resistor which switches automatically to non-emulation mode if ENE is
not connected.
STOP
Emulation control line; Driving a low level during the input phase freezes the real time
relevant internal peripherals such as timers and interrupt controller.
Opcode Fetch
Emulation control line; A high level driven by the controller during output phase
indicates the beginning of a new instruction.

CVBS input for the acquisition circuit.
In slave mode Horizontal sync input or sandcastle input for display synchronization .In
master mode HS or VCS output.
Vertical sync input/output for display synchronization.
Can also be used as digital input P4.7.
Furthermore this pin can be selected as an ODD/EVEN indicator alternatively to P3.0.
A low level on this pin resets the device. An internal pull-up resistor permits power-on
reset using only one external capacitor connected to Vss.
Output of the inverting oscillator amplifier.
Input of the inverting oscillator amplifier.
Red
Green
Blue
Contrast reduction and blanking.
Control output; indicates a write access to the internal XRAM; can be used as a write
strobe for writing data into an external data RAM by a MOVX instruction.
This signal is also available as P4.3.
Control output; indicates a read access to the internal XRAM; can be used for latching
data from the data bus into an external data RAM by a MOVX instruction.
This signal is also available as P4.2.
All the pins prefix by Flax are test pins which must be left open.
