Have had the set for 4 years or so. I have a cable box and dvd hooked up to the tv. The remote doesnt work when the problem is occuring. The tv doesnt even turn off by the remote or the power button on the set itself. So that is why i resulted in unplugging it. The problem has just started recently, I did have trouble the past few days with the picture coming in and out, but thought that it was just my cable connection until today.
Just plugged it back in and is working normally. No, the light was not blinking at anytime during the problem. Never had an issue with it powering on or suddenly turning itself off.
estimate on repair and/or if i would be better off with a new purchase
