Asking why is the Vizio sound bar blinking no sound? Keep reading to find out!
Whenever your soundbar doesn’t output any sound and all you’re seeing is a white LED, there is most likely a problem with the settings of your soundbar.
It is not excluded that a reliable power supply is missing, but in most cases, a reset might resolve the problem.
To solve the problem, hard reset the Vizio soundbar and make sure it is connected to the correct input on your playout device. Connect a different device to your soundbar to test and if you’re still experiencing troubles and if nothing helps, factory reset the soundbar.
Let’s check what might cause such an issue, by summarizing the well-known causes.
Once you’re familiar with what could be happening, we’ll continue with the best solutions available.
Why Vizio Sound Bar Lights Flashing No Sound?
Your soundbar could be flashing due to several reasons. Flashing light and no audio coming out of the device are generally considered two separate problems.
However, their causes could be in common, since there is not much that can go wrong, especially with a soundbar.
Here are some of the most frequently reported causes for no audio issues on the Vizio soundbar:
1. Power Problems
An issue related to the power supply of your soundbar might cause its LED to pulse without outputting any sound.
2. Bad Settings
Sometimes wrong settings configuration might result in problems with your soundbar’s output.
3. Wrong Input
In case the Vizio soundbar isn’t connected with your TV through the right input, you could be getting similar problems.
4. Demo Mode
If your soundbar is running on demo mode as a result of a restart or reset, it might be unable to connect with your TV, therefore it won’t output sound.
5. Connection Problem
A connection outage of the Vizio soundbar might also cause it to stop channeling sound.
After reviewing the possible reasons that could be causing the issue on the Vizio soundbar, let’s now learn how to resolve the problem in a few easy solutions.
How To Fix Vizio Sound Bar Blinking No Sound?
First, we suggest rebooting your soundbar, to see if that would fix the problem.
A simple restart will reboot all services and probably solve the problem if it’s related to a service failure or something minor.
If the restart didn’t help, then proceed with a more advanced way to restart your device:
Solution #1 Hard Reset Your Soundbar
It is recommended to hard reset your soundbar to power cycle the device.
If the problem is power-related, then this process might help your soundbar to refresh, therefore resolving any issues with the sound, connectivity, and power.
To hard reset the Vizio soundbar, follow the steps down below:
- Unplug your soundbar’s power cable.
- Wait for 5 minutes until the device completely cools off.
- Re-attach the power adapter into the respective wall outlet.
If you’re getting second thoughts on the power supply’s reliability, you might also want to plug your soundbar into a different power outlet.
Tip: Avoid using any strips or dividers that might be faulty and interrupt the soundbar power delivery.
Solution #2 Refresh Soundbar’s Connection
There is a quick workaround past this problem that is contained in simply holding 2 buttons on the Vizio soundbar.
It may not sound like much, but this process will refresh the connectivity of your soundbar with the playout device.
Follow the steps down below to refresh your soundbar’s connection:
- Make sure your Vizio unit is up and running.
- Locate the Bluetooth and Input buttons on your soundbar.
- Double-check if the LED on your soundbar is lit.
- Press both, the Bluetooth and input button for 6 seconds.
- Release once the LED flashes once.
That will basically restart the service responsible for connecting the soundbar to your playout device and hopefully solve the problem.
If however, the sound is still not there, continue with the next solution.
Solution #3 Refresh Soundbar’s Interface
This solution is held by two general processes. Both of them will refresh your soundbar’s interface in one way or another.
Down below we have explained both of the ways to refresh your soundbar’s interface.
- Hold input and volume UP button – On your soundbar, press and hold the input and the volume up button for around 6 seconds and release.
- Hold volume UP and input button – This process is the opposite of the previous one, where your first have to press & hold the input button and then the volume up for 6 seconds.
If this solution doesn’t seem to resolve your soundbar’s problem either, proceed with our next recommendation.
Solution #4 Correct The Input
In case the Vizio sound bar blinking with no sound it may not be plugged into the correct input on your TV or playout device.
There are multiple different ports on your TV that are meant for audio, video, television, and so on.
You will want to connect your soundbar’s cable to the “Audio Out” input on the back of your TV.
This slot is meant for sending audio out of your TV, therefore causing your soundbar to output what the TV plays.
Correct the input and check if the audio on your soundbar is going to be resolved.
Note: You should check if the default audio output of your TV is selected to be the soundbar instead of the in-built TV speakers. You can locate this option in the audio settings.
Solution #5 Try With A Different Device
We recommend trying your soundbar with a different device than your TV.
There is a chance that the problem is with the TV, but not with the Vizio soundbar, hence, you won’t be hearing any sound coming out of your soundbar.
If you have an available option to test the Vizio soundbar with an alternative device, make sure to try it out.
If everything seems to be working with the second receiver, then we suggest resetting your TV’ settings to fix the problem.
Solution #6 Reset Your Soundbar
If you’re still experiencing troubles after all of the solutions above, perform a reset on the Vizio soundbar.
This will permanently delete all optimizations in regard to settings and features, so you will have to set up all options of your soundbar individually, once the process is complete.
Follow the steps down below to factory default reset the Vizio soundbar:
- Ensure that your soundbar is currently working.
- Locate the Bluetooth button and the Volume down button.
- Press both, the volume down and the Bluetooth button, simultaneously.
- Hold them for about 5 seconds.
- Wait for all 12 LEDs to blink three times.
Once the LEDs flash, your soundbar is reset and ready to be re-configured. In case the problem is still there, that would make the impression of a hardware failure.
Make sure to contact Vizio customer service and after confirmation, seek a repair service or use your warranty.
