Troubleshooting 2 Blinks Error Code

Troubleshooting 2 Blinks Error Code

When troubleshooting a PDP TV that is shutting down and the power LED blinks 2 times:

Find out if 15V is output at pin 1 of connector P6 of the P board. If 15V is present, it’s likely that the A board is defective.

If no voltage is output, determine if this is caused by the P board or the boards using the P15V.

The boards connected to the P15V can only affect the P15V if there is a short circuit drawing excessive current.

To check for a short circuit, measure the resistance between pin 1 of connector P6 and ground (Chassis). If P15V is shorted, find out if the short is coming from the P board or if it’s coming from any of the other boards that the 15V volt is connected to.

If the P board is OK, disconnect the connectors providing the P15V to all these boards while measuring resistance between pin 1 of connector P6 and ground.

The defective board is found when the connector that provides the P15V to that board is removed and the short circuit is no-longer present.
