I have had this T.V. for about five years and have never had an issue with it until now. I was in the middle of watching T.V. when the screen went black, no picture or audio, and instead of the constant blue light that is in the sensor strip, there was a flashing red light. I unplugged my T.V. for a few minutes and plugged it back in, the screen remained black, no picture or audio, and still had the flashing red light. How do I solve the issue to get picture and audio back?
