How to identify SOS Blinking signal.
- When an abnormality has occurred in the PDP module, the protection circuit operates and reset to the stand-by mode. At the same time, the defective PC board can be indicated by the number of the pulse at Pin-3 [LED_R] of D8 connector on D8 board.
To check:
Connect the V1 board to D8 connector on D board, and turn ON the power (SS34) of PDP module.
If the power is shut down by protection circuit, the Red of LED V1 board will be shown as blinking.
