This Vizio Sound Bar Troubleshooting Guide Is The Best I’ve Ever Seen

About 10 years ago, when something goes wrong with our gadgets, we immediately call customer care. We go on and on explaining the problem, which typically ends in us buying a spare part or a new gadget altogether.

But this era of free information online has provided us with a plethora of options on how to fix this and that. The only problem now is, which do we follow and which is guaranteed to give us results.

Sound bar troubleshooting, in general, is not new to this case, and so are Vizio sound bars. There is plenty of information, but you don’t know which fix really works.

So I did a lot of research, and I figured this is the best Vizio sound bar troubleshooting guide there is. It’s simple and easy to follow.


The Common Problems and Their Solutions

1./ No Audio

The Problem

This happens when no matter how high you turn up the volume, you can’t hear any sound or noise coming from the sound bar.​

​The Solutions

​1. Make Sure the Audio File has Sound

​This happens when you think your Vizio sound bar is broken because you can’t hear anything. Before trying any fix, disconnect the device from your sound bar and check from your TV or where you’re playing it if it has sound. If there’s none, then you have a broken file. Otherwise, proceed to the next steps.

Oh, one more thing. Make sure your sound bar is not on mute.

2. Make Sure the Sound Bar is Powered On

More often than not, the main reason our sound bar is not producing any sound is it’s not turned on. Check if the light on your Vizio sound bar is on. Otherwise, turn it on using your remote or pressing the on/off button on the sound bar.

3. Make Sure the Cables are Properly Attached​

Loose connection of cables may cause the trouble with the sound bar’s audio. Check the connections behind your TV or any media player and the ones behind your sound bar to see that they are securely connected.

Another angle you have to check is what is attached where. For RCA cables, for example, it is usually color coded so you have to make sure the red plug is connected to the red port and the white to the white port.​

4. Make Sure the Cables are Not Damaged​

Damaged cables, especially ones whose internal wires are already exposed, may cause the cable not to function properly. This is usually caused by the usual wearing out and when we place them wires underneath heavy objects such as TV deck, couch, etc.

First, try fixing the cable using electrical tapes or heat-shrink tubes. If they don’t work and you’ve tried every DIY cable fixing there is, it’s time to get brand new ones.​

5. Make Sure the Sound Bar is On The Correct Input

You might be trying to play a file from your TV connected via cables, but your Vizio sound bar is trying to get a signal from a Bluetooth connection. To check, press input on your remote and it will display the device the sound bar is currently playing from.​

​2./ The Sub is Not Working

The Problem​

​You have been watching your favorite action movie, when all of a sudden you realize you're missing something boomy. You go to your sub, and you see it there. In the corner. Lifeless.

​The Solution​s

​1. Make Sure It is Powered On

Again, we all have our senior moments. Check the power cord of your sub and make sure it’s plugged. Then check the back of the sub and see if the power button is switched on.

2. Make Sure Its Volume is Turned Up​

From your remote, press menu and choose the setting for the subwoofer. Adjust its volume accordingly.

3. Make Sure It is Paired with The Sound Bar​

To check, look at the pairing indicator at the back of the sound bar or subwoofer. If the led indicator is blinking slowly, the sub isn’t paired. Press the pairing button on the sound bar for five seconds then on the sub for another five seconds.

The led light at the back of the sound bar will blink fast while the indicator on the front of the sub will light up.​

4. Make Sure There’s No Obstruction Between the Sound Bar and The Sub​

Any object that blocks the line of sight between the sound bar and the sub will cause the sub not to function properly.​

5. Make sure it is within the recommended distance

​When pairing the sub and the sound bar, the initial distance should be one foot away. After it has been paired, you may place the sub where it sounds best.

Note, however, that there is a recommended distance between the two, so be sure to check your manual.​

3./ Static Sound

The Problem​

​A static sound is that irritating high-pitched, irregular noise you get from your speakers. Merely describing it annoys me.

​The Solution​s

​1. Make Sure Your Cables are Seated Properly

Loose connection may also cause static noise, so make sure you plug all your audio wires to each port properly.

2. Make Sure You’re Using Undamaged Cables​

Frayed cables for whatever reason may cause static noise. Cover it up with electrical tape or heat-shrink tubing or replace them.

3. Use Another Output​

For some reason, an audio output may not be compatible with your audio source. Try switching to a different source and see if the problem is eliminated. Otherwise, it may be the sound bar that has the problem.​

​4./ Sound Bar Won’t Turn On

The Problem​

For unknown reason, your Vizio sound bar won’t turn on. No lights. No sound. Nothing.​

​The Solution​s

1. Make Sure The Circuit Breaker Isn’t Tripped

If you experienced a power surge because of lightning or having too many devices plugged in a single outlet, the outlet’s circuit breaker might be tripped. Try resetting it and turning on the Vizio sound bar again.

2. Make Sure the Power Cable is Not Damaged​

Again, a damaged cable may mean dysfunctional gadget. Check your cable if it needs fixing or replacing.

3. Make Sure the Remote is Working Properly​

If you’re trying to turn on your Vizio sound bar using your remote, make sure there’s no obstruction between your remote and the IR receiver in your sound bar. Also, check if your remote has enough juice or if it’s not yet damaged.

5./ Sub Won’t Pair

The Problem​

​The sub and sound bar are both turned on, but they are not paired. Sometimes they do; sometimes they don’t. It’s like a love and hate relationship.

​The Solution​s

​1. Make Sure there’s a Clear Line of Sight

Since these devices use wireless connections, it needs to get rid of any obstruction between them, especially along the receivers. Remove any object that may be blocking this.

2. Make Sure They’re Within the Connecting Range​

Although these two will still connect within 60 feet from each other, it’s best if you can move them a bit closer to each other.

3. Make Sure to Power Cycle Them​

Using them for a long time, especially if we leave them powered on continuously, leads to unused energy build up. To solve this, unplug both devices for about 30 seconds. Plug them again then re-pair them.

It’s best if you do this with the devices within one foot apart and they’re facing each other.​

​If All Else Fails

If all else fails, play dead according to an adage. But seriously, sometimes, it is beyond our DIY power to fix our gadgets’ problems. And not even this Vizio sound bar troubleshooting guide can help.

If that happens, call customer care up. I hear Vizio people are kind enough to replace your item if your problem is proved to be a factory defect. Otherwise, they may also offer you with the repair services either for free or a minimal charge.

If asking for someone else’s help still ends in you having to buy a new sound bar, you check out my other post about affordable sound bars and Bluetooth soundbars.
