I just tried to turn on my 42 Inch plasma and when I hit the power button, the red LED (power indicator) flashes for a period of time.
I have tried unplugging, turning the power hard off and have not had any success.
I don't think it's an input issue b/c when the input is off, I still get the screen to be black and get the HDMI signal box and the power LED stays on. I'm going to call Panasonic in the AM, but wanted to see if anyone had any experience in this?
