Fixing the power source:

You might not have anticipated this; however, one sneaky problem that no one ever thinks about could be an ill-fitted power source. If your Vizio soundbar is not correctly plugged into the power source, it will start acting up and flashing a white light. 

So, ensure that the Vizio soundbar is plugged correctly into the power source and that the power source is not faulty either.

Reset the Vizio Soundbar:

A typical IT joke is resetting the product no matter the problem!

Well, the same is true for the Vizio Soundbar Flashing white light. You can fix this problem by resetting the soundbar. Now, you might want to know the steps to reset the Vizio soundbar, so we have jotted them down for you below. Before you start, know that the resetting steps may differ slightly depending on your Vizio soundbar model.

Soft Reset:

  1. Power off the soundbar and unplug the power source.
  2. Now, press the power button for 30 seconds and plug the power cord back.
  3. Restart the soundbar to see if the problem is solved.

You may proceed to the hard reset if your problem is not solved. Here’s how you can hard reset your Vizio soundbar.

  1. Turn on the Vizio soundbar if it’s not on already.
  2. Next, hold the Volume down and Bluetooth button simultaneously for about 5 seconds. 
  3. Keep an eye on the flashlights of the soundbar. Once they flash three times, you’ve successfully reset your Vizio Soundbar.

Your Vizio soundbar should stop flashing white light by now; however, if the problem remains, you may proceed to the next step.

Check For Firmware Updates:

The Vizio Soundbar White lights might be flashing to tell you that a new firmware version is available and needs to be downloaded. So, head to the Vizio website, download the latest firmware available for your Vizio soundbar model, and install it through a USB drive.
Access the settings menu of the soundbar and look for any available updates. 

If this doesn’t work well for you, proceed to the next step for fixing the stubborn Vizio soundbar.

Check the audio connections:

As mentioned earlier, a problem with the audio connection could be why your Vizio soundbar is flashing white light. So, check your cable or Bluetooth connection with the TV or audio source. See if all the cables are plugged in correctly. Suppose you have connected the soundbar to the TV through a Bluetooth connection. You may disconnect and try pairing again.  If you need help with that specific connection, check our guide here.

Here’s what you need to do!

  1. Press and hold the Bluetooth button for 5-6 seconds. 

See if the cables are correctly plugged in or damaged. If the cables are damaged or faulty, you may change them to fix the problem. 

Exit the Demo mode:

If nothing is working so far, and you have almost given up the idea of getting the same old Vizio soundbar back, then wait!

Don’t lose hope.

The lights might still flash because the soundbar is stuck in the demo mode. So, you only need to exit the demo mode to get the soundbar working again. 

Don’t call the fairies now, For God’s Sake! 

It’s something you can do even with your eyes closed. Just follow the steps given to exit the demo mode. However, before you start, you must remember that these steps may vary depending on the model you’re using, so it’d be best to read the manual to reconfirm the accurate steps for exiting the demo mode.

Now, let’s see the steps.

  1. Use your Vizio Soundbar remote and press the Menu or Setting button on the remote.
  2. Navigate through the Menu to find the option “Demo Mode.”
  3. Now, use the arrow buttons on the remote to Navigate and Disable the demo mode.

You can also exit the demo mode without using the remote. Here’s how you can do it.

  1. Press and hold the Bluetooth and Input buttons for five seconds until the LED lights flash four times. 
  2. This is a sign that the demo mode has been disabled successfully.

Last Stand!

If nothing seems to work, now is the time to get up and contact Vizio Customer Support. There might be a problem with the soundbar hardware or circuit, which you can’t fix until you’re an expert.

My Vizio SB46514-F6 soundbar, connected to a TCL 75S535 TV via HDMI ARC, intermittently disconnects during playback. Despite firmware updates and support assistance, the issue persists. The soundbar stops for about 5 seconds and then resumes, indicated by the LED lights. This happened twice during a 1.5-hour movie, with only audio interruptions. My sub is 10 feet away, behind a couch. Has anyone faced this? Feedback on resolving this would be appreciated. I’m disappointed with my first Vizio product due to these issues.

Hey, I’ve had similar issues with my Vizio too. Sometimes it just acts up for no reason. I think it might be a firmware thing? I dunno. But yeah, it’s super annoying. I’ve heard some folks saying resetting it helps, but didn’t work for me. Maybe try reaching out to Vizio again? Hope you get it sorted. And yeah, their products can be hit or miss sometimes.
