Contents
1. Since Panel Module and Front Filter are made of glass, handling the broken Module and Filter shall be
taken care sufficiently in order not to be injured.
2. Replacing work shall be started after the Panel Module and the AC/DC Power Supply become sufficiently
cool.
3. Special care shall be taken to the display area in order not to damage its surface.
4. The Panel Module shall not be touched with bare hand to protect its surface from stains.
5. It is recommended to use clean soft gloves during the replacing work in order to protect not only the
dis
play area of the Panel Module but also a serviceman himself.
6. The Chip Tube of Panel Module (located upper left of the back and surrounded by frame) and flexible
cables connecting Panel glasses to drive circuit PWBs are very weak, so shall be taken care sufficiently
not to break. If you break Chip Tube, the Panel doesn't display anything forever.

CAUTION FOR SAFETY
Please read this page before repair the monitor.
This page explains to following items for keep the safety of set and prevent to accident during
repair work.
We explain by symbol at happen the damage or injury when took wrong repair.
Warning This symbol means "possible to die or heavy damage"
Caution
This symbol means
"possible to damage or something will break"
We made the symbol as below, which are kind of following items.
This symbol means
"CAUTION"
This symbol means
"POSSIBLE to
ELECTRIC SHOCK"
This symbol means
"MUST"
This symbol means
"DO NOT"
Should be follows to instructions.
We indicates to cabinet, chassis and parts
by label, which are special attention part.
Please follow to note and [Safety Instructions]
of User's Manual.
Prevent the electric shock.
Please take care during working because
monitor has high voltage part and power
supply part.
Possible to die if you tough to these place
by miss take.
Please disconnect power plug during
overhaul, reassemble or change parts.
You will die or take damage by electric
shock if you touch to live part.
Use recommended components.
Please use to same characteristic compo-
nent, which is same as previous for your
safety and keep reliability especially marked
by
in parts list and circuit diagram.
It is reason of electric shock or fire if you
use non-recommended component.
Should be kept same style of wiring or component.
Monitor uses tubes or tapes, which made
by insulator, and some components are
keep distance from surface of PWB for
safety.
Internal leads kept from hot part or high voltage
part by clamper or styling, so please return to
original condition for prevent to electric shock
or fire.
Should be done safety check after finished.
Every part (removed screws, component
and wiring) should be returned to previous
condition.
Check around repair position for make
damage by miss take and measure the
insulated impedance by meg-ohm meter.
Confirm the value of impedance, that
value is more than 4M ohm.
It is reason for electric shock or fire if that
value is less than 4M ohm.
Nobody can check and repair to the code
and combination circuit of HDCP.
Never remove the shield case, which is
assembled to the code and combination
circuit of HDCP.

PRECAUTIONS
How to clean the plasma screen panel of the monitor
Before cleaning the monitor, turn off the monitor and disconnect the power plug from the power outlet.
To prevent scratching or damaging the plasma screen face, do not knock or rub the surface with sharp or hard
objects. Clean the screen with a soft cloth moistened with warm water and dry with a soft cloth. If it is not
enough, then use a cloth with mild detergent. Do not use harsh or abrasive cleaners.
How to clean the cabinet of the monitor
Use a soft cloth to clean the cabinet and control panel of the monitor. When excessively soiled dilute a neutral
detergent in water, wet and wring out the soft cloth and afterward wipe with a dry soft cloth.
Never use acid/alkaline detergent, alcoholic detergent, abrasive cleaner, powder soap, OA cleaner, car wax,
glass cleaner, etc. especially because they would cause discoloration, scratches or cracks.
1. Features
PW1 chassis
This chassis basically constitutes just a MONITOR to use with AVC (Audio Visual Control center). But it can con-
stitute AV MONITOR when applied the VIDEO board, and also a TV when applied the VIDEO board and the
TUNER board.
[Common Features]
Large-screen, high-definition plasma display panel
The 42-inch color plasma display panel, with a resolution of 1024 (H) x 1024(V) pixels, and the 32-inch color plasma
display panel with a resolution of 852(H) X 1024(V) pixels, creates a high-definition, large-screen (aspect ratio : 16:9)
and low-profile flat display. Free from electromagnetic interferences from geomagnetic sources and ambient power
lines, the panel produces high-quality display images free from color misconvergence and display distortion.
High Performance Digital Processor
A wide range of personal computer signals can be handled, from 640 x 400, 640 x 480 VGA to 1600 x 1200 UXGA.
Easy-to-use remote control and on screen display system
The remote control included eases the work of setting display controls. Further, the on-screen display system,
displays the status of signal reception and display control settings in an easy-to-view fashion.
Power saving system
The International ENERGY STAR power saver feature saves power consumption automatically when input sig-
nals are not available.
When connected to a VESA DPMS-compliant PC, the monitor cuts its power consumption while it is idle.
