    42PD9700C/U & 55PD9700C/U 7. Troubleshooting How to get to Burn-in mode This mode displays the test patterns of some single color raster in turn. These signals are from built-in gener- ator of panel. So it can be presumed that maybe the panel has some trouble when the screen of Burn-in mode is abnormal. Using the R-side control buttons with the set turned off (standby) can activate this mode. Press the SUB-POWER( ) button, INPUT SELECT(...

(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). PDP panel self-diagnosis function This function is for a PDP panel failure with no picture. 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. 2) Turn the power off by the SUB-POWER( ) button of the monitor or the remote control. Procedure: 1) Press the SUB-POWER( ) button and button on the bottom of the monitor at the same time, and keep it for more than 5 seconds after the power turned on.
  • Page 55 42PD9700C/U & 55PD9700C/U 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. 2) Turn the power off by the SUB-POWER( ) button of the monitor or the remote control. Procedure: 1) Press the SUB-POWER( ) button and button on the bottom of the monitor at the same time, and keep it for more than 5 seconds after the power turned on. 2) The monitor will be turned on, and it will display On-Screen Display of the Self-check result and the failure history as below. 3) Any operation would cancel the Self -Diagnosis mode. 4) The following table shows the OSD symbols and contents of failure PWB in which failure most probably would be allocated according to the number of blinks.
