SERVICE MANUAL (Rev.D)
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 Hitachi 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 to 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 to be touched with bare hand to protect its surface from stains.
5. It recommended to use clean soft gloves during the replacing work in order to protect not
only the display area of the Panel Module but also a 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 shall be taken care
sufficiently not break. If you break Chip Tube, the Panel doesn't display forever.
