What To Do if There is No Sound Coming from your Vizio TV

Posted by Jamie on December 15, 2018

Vizio is a TV brand that popped up in 2002 and very quickly became a major player in the domestic TV market. Although the TVs themselves are made under license in China, Vizio itself is based in Irvine, California and employs American workers as well as overseas. That’s one reason they became a popular brand, though the reality is that they deliver solid TVs at a very reasonable price. Of course, no TV brand is without issues, and some people have reported not being able to hear sound from their Vizio TV. Without seeing your physical setup and knowing how you’ve configured everything, troubleshooting TV audio remotely can be problematic. However, there are a few basic checks I can show you how to perform, and see if that gets you on the road to being able to hear as well as see your Vizio TV.

 

Troubleshooting no sound coming from Vizio TV

There are some basic checks that you can perform to see where the issue with sound is coming from.

Check the TV. Unplug the TV from the wall outlet and leave it for 30 seconds or so. Plug it back in and retest. This allows the TV to fully power down and reset. If the issue was a temporary voltage or power issue, it should now be resolved.

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

Check the feed. What is providing signal to the TV? Is it a cable box? Satellite? Stream? Change the feed to something different and see if the problem persists. If you have a cable box connected, stream something over WiFi or connect a laptop or mobile and cast something to the TV. If audio works when you change the feed, it is the feed and not the TV. If there is still no sound coming from your Vizio TV, it may be a fault or a settings issue.

Check external audio. If you use a sound bar or surround sound, remove it and use the default speakers to test. If you get sound, it’s the external hardware. If you don’t, it’s the TV.

Check audio settings. Access the audio settings on the TV menu and check the settings. You can return them to defaults by selecting Reset in the audio section. Confirm the change and retest. This should not really change anything but is worth trying.

Troubleshooting TV audio

When troubleshooting any technical issue, it is good practice to simplify the setup as much as possible. In this situation where we have no sound coming from a Vizio TV, you should remove all external audio and input devices except one. For example, I tend to connect a DVD player to the TV using HDMI and then SCART. I use a DVD I know that works and play it on the TV.

If there is audio, I know the issue is not with the TV itself. If there is no audio, I swap HDMI for SCART and retest. If there is still no audio, I know the TV itself is the issue. This immediately tells me I don’t have to spend hours working through a surround sound setup trying to find a problem when there isn’t one.

If you find yourself in this situation, you could check the audio settings as above or contact Vizio customer services. If your TV is still under warranty, I would make a warranty call and get it fixed. If your TV is out of warranty, you have a decision to make.

A known issue with early Vizio TVs was with the audio board. It formed part of the mainboard and had inherent weaknesses. Five components need to be changed to repair the fault which could be quite expensive. You may need to talk to a professional to get expert advice.

While LCD and LED TVs are cheaper than ever, they are usually cheaper to buy than repair. You may need to make a judgment call on whether to have your TV repaired or just replace it with a newer model. Only a professional TV repair guy can advise you properly there.

I have an older Visio Smart TV that has sound issues. When I first turn the TV on there is no sound. Sometimes it will, after a time, come on by it self. Other times I change the input around and then go back to the original input and the sound magically comes on. This problem started after I moved the television to a different residence

My problem is that on my channel 2 CBS this sound during the commercials completely goes away then when the program comes back on the sound comes back on. This is really weird and some audio on news doesn’t come on, or it probably wouldn’t bother me! TV is only 2 years old!
