Turning TV on from cold start, it will run ok for 10-15 mins, then will turn off. After about 45 seconds, it will turn back on and will do this cycle 45-sec off, 1-2 mins on over and over.
Replace the power supply, PN: BN44-00206A
It's easy to
locate, but requires adjustments once it is installed. Panel voltages
must be adjusted according the the specifications of the TV. There is
a sticker on the back of the plasma panel which provides each voltage
setting. You can reference this sticker to make the proper
adjustment. Using a DMM, connected between chassis ground and the
panel voltage you are adjusting, turn the adjustments on the power
supply very slowly, until you are measuring the specified voltage
within 0.5v. I hope this helps and good luck.

Thank you for the advice. I think that might have worked. Fortunately, Samsung had decided to pick-up the repair cost after arbitration. I'll just go by that, so my whole circuit board panel will be replaced.
