ANSWERS:

"masoncindy23  that could be pretty much anything. Time to remove the back cover and check all of your boards and your wiring. Make sure that all the connectors and wires are tight. Vizio has issues with bad connectors you may have to resolder. As for as what this could be, it could be the power board not supplying the voltages to the main board or the panel (bad backlight). Could be a failed T-con board or a bad main board as well. We have to see you boards etc. to try and determine what is going on. Post some good pictures of all of your boards with your question. That way we can see what you see. Use this guide Adding images to an existing question for that.
