6. Self-Diagnosis Function

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).

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.

*) This code is no meaning for the models except 32/42PD5000TA because those are without tuner circuit.

If you clear history of failure, make FACTORY RESET: enter the factory setting mode; press the SUB-POWER() button, INPUT SELECT() 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.
