SERVICE MANUAL

LCD
Be sure to read this manual before servicing. To assure safety from fi re, electric shock, injury, harmful radia-
tion and materials, various measures are provided in this HITACHI 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 the broken Module and Filter shall be
taken care suffi ciently in order not to be injured.
2. Replacing work shall be started after the Panel Module and the AC/DC Power supply become suffi ciently
cool.
3. Special care shall be taken to the display area in order not to damage its surface.
4. The Panel Module shall not be touched with bare hand to protect its surface from stains.
5. It is recommended to use clean soft gloves during the replacing work in order to protect not only the dis-
play area of the Panel Module but also a serviceman himself.
6. The Chip Tube of Panel Module (located upper left of the back and surrounded by frame) and fl exible
cables connecting Panel glasses to drive circuit PWBs are very weak, so shall be taken care suffi ciently
not to break. If you break Chip Tube, the Panel doesn't display anything forever.

    55PD8800/37LD8800 8. Self-Diagnosis Function (PDP only) This chassis has 2 modes of self-diagnosis function. (1) PDP panel check mode: It indicates the one latest record of the PDP panel failure with blinking of the power indication light (LED). (2) Signal circuit check mode: It indicates the check result on some points of the signal circuit and the history of them with On-Screen Display (OSD).
  • Page 53 55PD8800/37LD8800 Signal circuit self-diagnosis function This function is for the failure of the signal circuit, for example the phenomenon as below: "Sometimes power turns off abnormally." "Sometimes picture disappears abnormally." To enter to this Self-Diagnosis mode, follow the next steps: Preparation: 1) The Power Cord should be connected to AC line and the Main Power switch should be turned on.
