I can mimic the sound issue on the Vizio tv by hitting the Menu button, if you have sound and you select the Menu button on the Vizio tv, the sound will go off and you will then have to go to input section and select smartcast again and then back to HDIM-1.Īnother thing that you can do is, if you don’t have sound when you turn on your TV, go to Netflix or Amazon TV, sound should come on, then go back to your main TV, the sound should remain. When you do this, the sound comes back on again

On the Vizio tv, once it’s turned on and you don’t have sound, go to input selector on the Vizio tv and select Smartcast as the input selector, once you select Smartcast, it will go to smartcast, at that time, select input again and go back to your main selector for either cable or TV input (mine was HDIM-1).

Change the feed to something different and see if the problem persists. If you use HDMI, definitely swap for a spare to test as HDMI cables, particularly manufacturer-provided cables, are notoriously flaky.Ĭheck the feed. Have any of the cables been knocked or moved? Make sure all are seated fully and swap out different cables if you have spares. This is usually the second thing to test.
