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.
