(PW1A) Caution
Be sure to read this manual before servicing. To assure safety from fire, electric shock, injury, harmful radiation and materials, various measures have been provided for in this HITACHI Plasma display service manual. Be sure to read all cautionary items described in the manual to maintain safety before servicing. Service Warning
1. Since the Panel Module and front Filter are made of glass, handle a broken Module and/or Filter with sufficient care, in order not to be injured.
2. Repair work should not be started until after the Panel Module and the AC/DC Power supply have cooled sufficiently.
3. Special care should be exercised in the proximity of the display area in order not to damage its surface. 4. The Panel Module should not be touched with bare hands, as this will protect its surface from stains. 5. It is remended to use clean soft gloves during the repair work in order to protect not only the display
area of the Panel Module but also the technician. 6. The Chip Tube of the Panel Module (located in the upper left corner of the back of the glass panel)
is very fragile; as well, the flat cables connecting the Panel to the drive circuit PWBs are very weak. Take care not to damage these, otherwise, the panel will never light again. Contents 1.
