There can be several reasons for this problem. It could be a hardware issue, or it could be a software/firmware issue.

We can’t claim that the below-mentioned tips will fix the problem for you, but they work in most cases.

Here are some of the most common reason’s why your Vizio soundbar automatically turns off or on

  1. Software related issues
  2. Firmware update needed
  3. Multiple TV setups
  4. Eco settings (Power saving mode)

One of the common reasons for this problem is outdated software or firmware. Vizio regularly releases firmware updates for its soundbars.

These updates not only improve the device’s overall performance but also fix bugs and glitches.

Update the soundbar to the latest firmware to see if it fixes the problem. You can update the firmware using the Vizio SmartCast app.

Conversely, if you have recently updated the soundbar to the new firmware, that is when the problem started.

We recommend you reset the device to factory defaults to erase the new firmware settings.

Step 2: Toggle Off the Eco Mode

Vizio Soundbars with ‘Echo Mode’ enabled can automatically turn off after a certain period of inactivity.

Though this mode saves energy, it can cause the soundbar to turn off randomly. To fix this problem, you need to disable the ‘Echo Mode’ using a remote.

Step 3: Tweak Your Conncected Devices Settings

When the Vizio soundbar is connected to multiple devices, it is possible that it is getting turned off by one of the devices.

For instance, if you have a Vizio Soundbar connected to a TV and a gaming console through HDMI, it is possible that the gaming console is sending a signal to turn off the soundbar.

To fix this issue, set up the soundbar in a way that only receives power input signals from the TV.

Why does my Vizio sound bar keep disconnecting?

Again, your Vizio soundbar turns on by itself because it could be a problem with the wireless connection, the power supply, or the sound bar itself.

To recap, if your Vizio soundbar keeps turning off, it is recommended to try the following troubleshooting steps:

  1. Ensure the remote control is properly paired with the sound bar and the batteries are fresh.
  2. Check the power cord and connections for any damage or lose connections.
  3. Reset the soundbar by unplugging it from the power source and waiting for a few minutes before plugging it back in.
