My Vizio flat screen tv won't power on sporadically! The Vizio name lights up bright and the Vizio icon appears in the middle of the screen but sometimes that's all it does
After the name and icon light up that's all it does, and won't power off when the power button on the back or remote are pressed. It then has to be disconnected from power to try again, and again and again. Sometimes it will power on but most of the time it won't. What module do I need to purchase?
