Caution
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 Recommended temperature range per part:

8. Re-Adjustment
changing the Panel Module, re-adjustment is needed according to the item 8.1.to 8.5. For Power Unit, item 8.1; for Signal Board, item 8.2 to 8.5* and for Video Board, item 8.2, 8.4,8.5 are needed. It is recommended to start re-adjustment after 30 minutes warm-up with the Burn-in signal.
*) When it is not inserted into VIDEO Unit of optional Board in Signal Board replacement, VIDEO Unit becomes necessary. In this case, insert the dummies' VIDEO unit and execute the above adjustment item.
How to set to Burn-in signal (red, green, blue, white, yellow, cyan, magenta, black signal) Turn off the sub power button (or power button on the Remote Controller), then turn on the SUB POWER button for more than 5 seconds while you keep pushing VOLUME and RECALL buttons located on the bottom of the set.
When you fall out from Burn-in mode, turn off the sub power button (or power button on the Remote Controller),then turn on the SUB POWER button for more than 5 seconds while you Keep pushing VOLUME button located on the bottom of the set.

*Fig.1 Adjustment Signal
How to adjust (VIDEO input) 1.Input 525p(480p) adjustment signal into VIDEO2 input terminal. 2.Change CONTRAST of the MENU screen from DYNAMIC to LINEAR. 3.Service adjustment mode screen again 4.Select No.259. (RGB ADJ.) 5.Press [ENTER] button more than 2 seconds. * Start the automatic adjustment. 6.Complete the adjustment after disappear ADJUSTMENT indication. 7.Change CONTRAST of the MENU screen from LINER to DYNAMIC again. How to adjust (PC input) 1.Input VGA (60Hz) adjustment signal into RGB input terminal. 2.Indicate service adjustment mode. 3.Select No.259. (RGB ADJ.) 4.Press [ENTER] button more than 2 seconds. * Start the automatic adjustment. 5.Complete the adjustment after disappear ADJUSTMENT indication. *Never adjust without use our specify signal. If press [ENTER]button at No.259 by mistake, the picture becomes abnormal (Black level, Contrast and Color.)

8.3 Color temperature adjustment for PC How to prepare 1.Set signal generator output signal to Full White. 2.Signal condition VGA (75): 0.7Vp-p, Set up level: 0V 3.Input the signal into RGB (D-sub) terminal. 4.Set Picture setting up to reference.
How to adjust 1.Indicate service adjustment mode and adjust as follows by Remote Controller. 2.Measurement probe of CRT Color Analyzer CA-100 is set on the center of screen. 3.Adjust color temperature as follows by reducing one or two numbers of No.9, 10, 11. (At least one of these datas should be 255.)
PC color temperature (COOL) x=0.285±0.005, y=0.294±0.005, at 9300 K ± ± 4. Adjust color temperature as follows by reducing one or two numbers of No.12, 13, 14. (At least one of these datas should be 255.) PC color temperature (NORMAL) x=0.300±0.005, y=0.298±0.005, at 7600 K ± ± 5.Adjust color temperature as follows by reducing one or two numbers of No.15, 16, 17. (At least one of these datas should be 255.) PC color temperature (WARM) x=0.314±0.005, ± y=0.327±0.005, ± at 6500 K
Suggestion 1.Luminance of panel surface is less than 20 lux to arrange adjustment environment. 2.Adjstment is reduce value adjustment only. (Impossible to increase value adjustment.) 3.Color select mode is automatically set to COOL while adjustment No.9, 10 and 11. 4.Color select mode is automatically set to NORMAL while adjustment No.12, 13 and 14. 5.Color select mode is automatically set to WARM while adjustment No.15, 16 and 17. 8.4 Color temperature adjustment for Video How to prepare 1.Set signal generator output signal to Full White. 2.Signal condition 480i/60Hz Component signal Video level: 0.714Vp-p, Sync level: 0.286Vp-p Set up level: 0V 3.Input the signal into VIDEO2 terminal. 4.Set Picture setting up to reference. 5.Make sure that CONTRAST is LINEAR. 6.Do after color temperature adjustment of PC.
