CMP4121HDE CMP4202E 42PMA400E

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. Replacment 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 to be touched with bare hand to protect its surface from stains.

5. It is recommended using clean soft gloves during the replacment 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.

1. Features

 42 inches Hi-Vision compatible high-definition color plasma display panel.  Newly developed Multi-scanning converter provides a multi-scan coverage of TV signals

through to PC analog signals (15 kHz to UXGA(107 kHz)).

 Large high-quality display images free from color miss-convergence and display distortion, as

well as from geomagnetic effect and the magnetic effect of ambient power lines.

 Multimedia input support

Two minis D-sub terminal have been provided for RGB input. It is possible to switch between RGB signals and component signals* from the Menu screen or the remote controller, therefore use is possible with equipment ranging from personal computer to imaging device. *It is possible when the VIDEO unit is inserted.

3. 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 

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 higher than leaded solder.

Servicing 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 
