7. Self-Diagnosis Function
PDP panel self-diagnosis function
This function is for a PDP panel failure with no picture.
Panel failure is automatically self-diagnosed.
It is shown by the blinking of the power indicator light (blue).
The next table shows the PDP PCB in which failure most probably would be allocated according to the
number of blinks.

1) Main Power switch-off operation cancels the Self-Diagnosis mode.
2) Priority is given when a FAN error occurs (shown by red blinks).
