The guy above is spot on try what he says .

Replace your battery.

there is a short or old heat sink in the television I recommed takin it to a licensed television repair service

Contact Panasonic Tech support..tell them series of flashes

Has the tv been getting dim? If so it's the lamp. Mine did the same thing.

What I would do is turn it off completelly for a few minutes. take out the battery and let it cool down for a few minutes. If you have a battery that if fully charged put it back in and turn on your phone. if your battery is not totally charged, charge it. A phone whose battery is not fully charged may cause your phone to flip out. sometimes it's also water damage to the phone that causes it to turn off on its own.
Water damage happends from body heat, from taking it to the bathroom when you're in the shower, or from putting it directly in water.

Hope this helps.
