Be sure to read this manual before servicing. To assure safety from fire, electric shock, injury,
harmful radiation and materials, various measures are provided in this Plasma display.
Be sure to read cautionary items described in the manual to maintain safety before servicing.
1. Since Panel Module and Front Filter are made of glass, handling of the broken Module and
Filter shall be handled carefully in order not to be injured.
2. Replacement work shall be started after the Panel Module and the AC/DC Power supply become
3. Special care shall be taken to the display area in order not to damage its surface.
4. The Panel Module shall not to be touched with bare hand to protect its surface from stains.
5. It is recommended using clean soft gloves during the replacement work in order to protect not
only the display area of the Panel Module but also the serviceman himself.
6. The Chip Tube of Panel Module (located upper left of the back) and flexible cables connecting
Panel glasses to drive circuit PWBs are very weak, so sufficient care should be taken so as
not to break them. If you break the Chip Tube, the Panel will not display any more.
SPECIFICATIONS AND PARTS ARE SUBJECT TO CHANGE FOR IMPROVEMENT.

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 neu-
tral 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.
Large-screen, high-definition plasma display panel
The 42-inch color plasma display panel, with a resolution of 852 (H) x 480(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.(RGB Analog input)
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 signals are not available.
When connected to a VESA DPMS-compliant PC, the monitor cuts its power consumption while it is idle.

4. Service points
Lead free solder
This product uses lead free solder (unleaded) to help preserve the environment. Please read these
instructions before attempting any soldering work.
Caution: Always wear safety glasses to prevent fumes or molten solder from getting into the eyes. Lead
free solder can splatter at high temperatures (600°C).
Lead free solder indicator
Printed circuit boards using lead free solder are engraved with an "F."
Properties of lead free solder
The melting point of lead free solder is 40-50°C higher than leaded solder.
Solder with an alloy composition of Sn-3.0Ag-0.5Cu or Sn-0.7Cu is recommended.
Although servicing with leaded solder is possible, there are a few precautions that have to be taken. (Not
taking these precautions may cause the solder to not harden properly, and lead to consequent malfunctions.)
Precautions when using leaded solder
Remove all lead free solder from soldered joints when replacing components.
If leaded solder should be added to existing lead free joints, mix in the leaded solder thoroughly after the
lead free solder has been completely melted (do not apply the soldering iron without solder).
Servicing soldering iron
A soldering iron with a temperature setting capability (temperature control function) is recommended.
The melting point of lead free solder is higher than leaded solder. Use a soldering iron that maintains a high
stable temperature (large heat capacity), and that allows temperature adjustment according to the part being
serviced, to avoid poor servicing performance.
Recommended soldering iron:
Soldering iron with temperature control function (temperature range: 320-450°C)
Recommended temperature range per part:
