My Vizio occasionally has no sound when I turn it on. I unplug and then plug it in again and it's back. As for the remote, it's goes through batteries like crazy. We seem to replace them every other month lately. It didn't used to be that way.
Switch to a different input device and verify there is sound from the TV speakers (for example, a DVD player or a gaming console). Turn the other device on and then use the INPUT button on the remote to switch to that device. Then attempt to play a DVD or game to determine if the TV speakers produce sound. If you do not have another device, and your TV is a VIA Smart TV you can test with any video application.

Thanks for the quick response. After working through the suggestions, I still have a clear picture with no sound. My remote does not 'speak' to the TV either. Curious if the two problems are connected.
I have exactly the same issue, requires shutting off the power surge protector and then it seems to work, a few times just changing input worked but not usually. Really annoying considering the price of these things. Also had issues with the casting, gave me an error that said sorry we lost our focus. WTF. So bought a roku and hdmi plugged it and that stopped but now we have the sound issue. hmmmmmm
I just purchased a Vizio 60 inch TV and had the sound issues straight out of the box.I have to turn it on then turn it off to get sound and about every 4th or 5th time I have to unplug the TV in the back then plug it bck in to get sound,this happens regardless of whether any audio equipment is hooked up or not,i guess im waiting for the day when it won't work at all....pretty irritating and causing me to not recommend this product to anyone.
I was having the same issue with the sound on my Vizio TV and nothing I tried worked, until I accidentally unplugged my Cable box. When I plugged it back in the sound came back and it has been fine ever since. Still not sure what the issue was but I'm just glad that it is fixed. Hopefully this will work for you!
The sound on my Vizio tv just randomly stopped working one day. I tried all the troubleshooting solutions but they didn't work. I even checked to see if the tv speakers were set to on in the audio menu, and they were, so then I grabbed my speaker bar and hooked it up to the tv and the sound still wasn't coming through on the speaker bar. I then went to the audio settings on the menu of the vizio tv again and it showed that the tv speakers were set to off this time so I turned them back to on and the sound was working on the tv again! Hope this was clear enough and helped some people that have tried everything else..
I have a Vizio 47" M479NV no sound, i have tried it all unpluging, resetting and changing settings. i think it the main board but how can i fix it and what do i need to look for on the board? Any one know?
We have had this same problem. Off and on for years, mostly when we were gone for a time and came back. Resetting seem to work. Then one day the sound went off in the middle of it working. We were told it was the main board. We found a main board on ebay. Could not find one anywhere else. We replaced the board. Still no tv speaker sound. I told my husband to try to turn the volume up on the tv and not the remote. Guess what? The sound came on, and now the remote works too. Worth a try. We are still expecting to go off again. We shall see. Give it a try. You have nothing to lose.
I had the same issue with a Vizio E Series tv. I tried the advice read here in disconnecting the power supply to the cable box. It didn't work. I then unplugged the TV and the sound returned after plugging it back up. The Vizio app for Android required resetting. Not sure what caused the problem.
Just got off the phone with Visio and thought I should share. Was told it is a glitch in the TV software. Unplug the power cord from the TV. On the back of the TV hold the power button for five seconds and release. Plug back in the TV and turn it on and problem should be resolved. Worked great for me!
I had tried all of the above plus online suggestions. Not the safest thing to do, but I left the tv plugged in and turned on, on hdmi although no volume could be heard and just unplugged the hdmi plug from the back of the tv ... counted to 5, plugged it in and the sound came back. This was the first vizio and will likely be the last. When it no longer works, back to the old try and true manufacturers.
By coincidence my 8 year old said just turn up the volume dad, which he did! My tv never lost volume, you just had to turn it up to 60 before you could hear it. The sound was better after I went into settings and turned on volume leveling, but still requires at least 30 or more on the volume before you can hear it. I would recommend cranking your volume all the way up and trying again. None of this started until Vizio updated my tv.
If I go to off & back to leveling the sound comes on (tho, I CAN'T listen on my ear buds thru the roku app)& if a new episode starts or I pause or rewind I have to hit the option button & repeat it all! Very frustrating! Should have gone with the Samsung Smart TV
Help? My audio on my vizio tv suddenly stopped working. I dont have external sound bar. I checked the connections on the cable and fire stick. Checked for sound w/ and w/o firestick, on cable and analogue/ digital tv. Checked the tv settings... and nothing.
Someone here indicated they spoke with Vizio and was told it is a glitch in the TV software. Unplug the power cord from the TV. On the back of the TV hold the power button for five seconds and release. Plug back in the TV and turn it on and problem should be resolved!!
UPDATED: SO, my post previously was Oct 3rd, and just yesterday it repeated the issue so unplugging the tv fixed the tv again but has proven to be a temp fix. Because a little over a week past and it did it again.
It has been discovered and i can turn it on and off but i want to know what i need to do in order to create scripts/automations or whatever i need to do to setup buttons on my home assistant dashboard to directly select apps like netflix and use navigation keys up down left right etc.
Of the 1.2% of user using this integration perhaps nobody has tried what you want to accomplish. Perhaps if you showed us what you tried that filed along with any errors others could assist, you need to understand your system anyway and not just copy a solution from others. Like the pinned thread says, This is not a HelpDesk.
I just brought a Broadlink RM4 in the end and stuck it to the back of the TV with the ir blaster facing down. Apart from the direct APP selection everything else worked prefectly. I just used the above code for selecting apps directly.
I looked into pyvizio briefly back when i was looking to do this and couldnt find alot of info on getting it set up. Im pretty new to home assistant as a package and couldnt find any real guide on how pyzivio gets set up. if you could provide alittle info that would be amazing.
I still plan on using the broadlinks as i have 1 on every tv as it gives temp and humidity for the room too which is a nice touch on the dashboard but to have a better integration for the tv would be ideal.
This is what the above code does. All modern Vizio TVs implement a REST API which you can post a JSON payload to it. If you read through the Vizio API docs on Github ( _SmartCast_API), everything is described there.
Then using that AUTH code, I can send commands to the TV just like a remote control but via REST and your home network. As you can see above, it allows you to control Volume, Mute, Cycle input (like pushing the INPUT button), using the D-PAD up/down/left/right and OK buttons, display the Settings or go Back. Everything you need.
I send to it the IP, Port, AUTH code, codeset and code shown in the table above and you have a remote on your screen. I will note that the pyvizio documentation lags behind the Javascript version referenced on that page. I had to read through both to get all of the key commands (codeset and code), especially those for the D-PAD. But you have them above.
