I have a Panasonic PT-60LC TV. After watching for a while, it turns itself off. The red light on the power button continues to blink. I wait for a while, and then it will turn on again, but continues to shut down randomly at no particular interval. Any suggestions?

How many times does the light blink?

The lamp indicator light blinks once every 5 seconds. The light on the power button constantly blinks red.
