There are a variety of issues that could cause your TV to lose audio. It's difficult to say if the issue is your source device, your cable, or your TV. We'd be happy to help narrow down and diagnose and resolve your problem. Please visit support.VIZIO.com and click on ‘Contact Us’. We’ve got agents ready to chat, text message, or speak with you on the phone.

Can you give us some additional details about the issue you are experiencing? This is not typical so I would like to learn more so we can assist with troubleshooting.

Hello JoAnn, so glad to hear you are loving your VIZIO! I can’t help noticing you left a great review but gave a lower star rating. For extended warranties, I would recommend to contact the retailer from which the TV was purchased from. They will have more information on the options for an extended warranty! If there is anything holding you back from giving us 5 stars I would love to offer the help of our award-winning technical support team. You can reach them by going to support.vizio.com and clicking ‘contact us’.
