Tim, this error can originate from the A-board, possible a bad diode etc. You may want to start off with this:"
Troubleshooting 10 blinks Condition At Plug In
These 3 conditions can cause the TV to shutdown and the power LED to blink 10 times
1. Missing/Shorted F_STB_15V
2. Missing/Shorted SUB9V, SUB5V, and SUB3.3V
3. Wrong diagnostic by the A board
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.
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.
Since some of the Sub-voltages generated by the A board are connected to the K, GS, and GH boards, it’s also likely that one of these board may cause the unit to shut down and the power LED to blink 10 times.
Disconnect connector A1/K1 to isolate the K board.
Disconnect connector A/52GS52 to isolate the GS board.
Disconnect connector A11/GH11 to isolate the GH board.
The defective board is found when the connector that provides the sub-voltages to that board is removed and the TV no longer shuts down.
Sub-Voltages Distribution
The F+15V from the P board is the source that supplies the DC-DC converter (IC5400 and IC5401) in the A board. The A board outputs 9V, 5V, and 3.3V.
The 9V is only used by the A board.
The 5V, besides being used in the A board, is also distributed to the K and GH boards.
The 3.3V is used in the A board and it’s also provided to the GH and GS boards.
A 10 blinks code from the power LED indicates abnormalities on any of these voltages.
Troubleshooting 10 blinks Condition At Power On
These 5 conditions can cause the TV to shutdown and the power LED to blink 10 times:
1. Missing/Shorted F_STB_15V
2. Shorted P15V
3. Missing/Shorted SUB9V, SUB5V, and SUB3.3V
4. Missing Vda (Shorted Vda causes 5 blinks)
5. Wrong diagnostic by the A board
Note: The P15V and the F_STB_15V are created by the same circuit in the power supply circuit. A shorted P15V, normally causes the TV to shut down and the power LED to blink 2 times.
Sometimes a shorted P15V affects the F_STB_15V and this causes the TV to shutdown making the power LED blink 10 times.
To troubleshoot a PDP TV that is shutting down and the power LED blinks 10 times:
Isolate the SC and the SS boards (They may cause a 10 blinks shutdown). Disconnecting P6 and P7 allows for only the panel drive section to be driven. If the LED on the SS board and the LED on the SC board are lit, then the SS and the SC boards are OK and the A board is suspected to be defective.
If the LEDs on the SS and SC boards are not lit, then isolate them one at time.
If the SS and SC boards are OK, then the P board may be defective." from here.
Since this can be an overheating error, you do want to also make sure that there is not excessive dust inside your TV and that you have good airflow.

It displays code 10 or blinks 10 times? What happened to the TV just prior to this coming up? what have you checked thus far?
