That indicates an abnormal temperature rise in the power supply. These plasma TVs are board replacement repair only. The power supply board seems most likely would have to be replaced. I hope you have warranty coverage. It could get quite expensive to fix.

This signals a hardware fault - more precisely it signals the fact that the power source is in protected mode because there's a short on one of its outputs.
To find out which actual part is the one that failed you must open the tv and test the power source with a voltmeter - the output which has a voltage much lower than the rated one (or even 0) is the one that powers the faulty part, follow it and test all the components.
