I have a Toshiba 55X81 with the same blinking power LED issue. They probably have the same power supply.
When it first started, many months ago, I could just unplug and replug it and it would be OK until I turned it off again. It has gotten progressively worse. The last time I was able to get it to power up, I just left the TV powered on 24/7. Worked like a champ! Of course yesterday I had a 5 second power outage and when the power came back on the LED was blinking. Unplugging/replugging had no effect this time.
I am now in "stuck" mode. I'm waiting for a couple of days before trying it again in hopes it may self-heal. Other than this problem, the set has been fine for a number of years.
