Plasma tv shuts itself off, blue power light blinks.

My PDP4280HD plasma tv shuts itself down after about 15-18 minutes of viewing, and the blue power light blinks 12 times. A warning bar comes on the screen saying "Plasma TV is loading." What's going on? Seems like a self diagnostic thing.

First guess would be power supply or another board is overheating after 15 minutes. Unfortunately replacement boards for that model are not common anymore.
