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 P7 of the P board.
If no voltage is output, measure resistance between pin 1 of connector P7
and ground (Chassis). If a shorted 15V is detected, find out if it's 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 P7
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.
