Troubleshooting a 5 Blinks Error Code

Troubleshooting a 5 Blinks Error Code

When troubleshooting a PDP TV that is shutting down and the power LED blinks 5 times:

Find out if pins 1 or 2 of connector P35 are shorted to ground. If shorted, possibly the panel is bad. If there is no short circuit, proceed to check the P5V line.

Find out if 5V is output at pin 5 of connector P25 of the P board.

If no voltage is output, measure resistance between pin 5 of connector P25 and ground (Chassis). If P5V is shorted, find out if it’s created on the P board or if it’s created on any of the other boards that the 5V volt is connected to.

If the P board is OK, disconnect the connectors providing the P5V to all these boards while measuring resistance between pin 5 of connector P25 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.
