Your set is entering protective shutdown. Most likely its a failure in the standby or start up voltages that is allowing a voltage to increase triggering the shutdown circuitry to prevent your set from starting. Do you have any trouble shooting skills?

Is your TV still under warranty? This problem seems common on this site with the Panasonic brand. I really can't say what exactly is causing this problem, but it seems like something in the power circuit board is faulty. My advice would be to call Panasonic's Technical Support Hotline and speak to a Technician. It could even be a problem that has warranted a recall of that particular model. The number for Panasonic's Hotline is 1-800-211-7262. Or, you can contact them via e-mail @ www.panasonic.com under "Get Support". Hope this helps...
