vizio 55 inch smart tv no sound diagnosis
woke up to no sound on my vizio smart T.V. here are a few suggestions to look at and diagnose. I will change the main board that has the amplifier IC on it. you can fix this by buying a sound bar and switching from T.V. speakers to FIXED speakers and using a outside source. product sold here.

I'm so aggravated I can't find any info for my problem. My TV speakers go in and out. The value buttons work and the surround sound system works so it's not useless but it sounds better with the TV speakers included plus sometimes I just want the TV speakers. It's my spare main room TV and it is old but unfortunately I purchased an LG TV a little over a year ago and a few of the LED's burned out and I haven't gotten around to changing them yet. Why would it work most of the time go off for a few seconds to minutes then come back and continue to do this?
Matt, The amp should be powering the speakers with AC and not DC power [voltage]. To have that much DC power [voltage] going to the speakers, your decoupling or filtering capacitors are probably shorted out allowing the DC current to pass through them and not block them. Speakers work on AC voltage. This allows the cone in the speakers to move in and out to create sound.
Hi Matt, thanks for all the info. I just got a used Vizio E371VA (2010) from Goodwill. Set it up; Video OK – looks good. No sound. Turned on speakers, reset sound to factory settings. Still no sound. Suggestions? I still have the receipt from Goodwill. I could return it. Is it worth the time and money to repair? Suggestions? I don't have an Ohm meter and don't have the skills you have at present. Thanks!
My Philips TV Sounds go off for a while and then comes back on it keeps on and off.. what could it be the problem?
My Vizio has picture and no sound, except there is no sound coming from any of the audio out jacks, either (including RCA and optical). I wish the video went another 2 minutes to explain what to do then.
Matt shaughnessy, my 55" Visio sound is no longer working☹. I bought a sound bar, but still nothing. I know the sound bar is good because it worked on my other tv. What can this be? PLEASE HELP!!
i had a problem with my tv too….
i turned it on and off and it worked
So what if there is no sound coming from the external speakers also? Is the main board still the problem or something else?
This is why I shouldn't have bought a vizio. They know about this sound problem and are not doing anything about it
Main board? Where do you recommend I purchase it
Thanks for your info on the Vizio "no sound".
My dad gave me a Viszo , and has not sound. Are you in Florida.
what if there is no power coming from the pins on the audio out to speakers.
