10 blinks Condition Troubleshooting
1. Missing/Shorted F_STB_15V, SUB9V, SUB5V, and BT30V
2. Wrong diagnostic by the A board
Since the Sub voltages are only present after the power has been turned on, there will
not be a 10 blinks condition at plug-in for the 2009 models.
These 3 conditions can cause the TV to shutdown and the power LED to blink 10 times
To troubleshoot a PDP TV that
is shutting down and the power
LED blinks 10 times:

Find out if 15V is output at
pin 7,8,or 9 of connector P6 of
the P board. If no voltage is
output, the P board may be
defective.

If the F_STB_15V voltage is
OK, it’s likely that the A board
is defective.
Note: When taking voltage reading, place the voltmeter probe at the test point, component, or
connector’s pin indicated before connecting the TV to the AC line. This will ensure voltage reading
accuracy before the TV shuts down.
