Why Vizio Soundbar Turns Off Itself

It’s an indication that the Auto Standby settings are on if your Vizio soundbar keeps turning off on its own. To reduce power consumption, the device automatically turns off after 15 minutes after the settings have been toggled ON. It is possible, however, for the Vizio soundbar to turn off automatically due to various factors, as follows:

Firmware out-of-date: Developers make updates for all devices to ensure the software is up-to-date and users are notified of any updates.

 Over time, Vizio soundbars also require regular firmware updates. A Vizio soundbar may turn off by itself if its firmware is outdated, so you need to make sure it’s up to date. Check out other fixes to resolve the problem if it’s not.

Faulty soundbar remote: The Vizio soundbar may fail if the remote is defective or incorrect. Since most remote controls look the same, users may use a different remote or a faulty remote to control the Vizio soundbar. Additionally, the soundbar automatically turns off if it is not used. Therefore, it is important to check if the remote control is compatible with the soundbar and if the batteries are working. Vizio soundbar can, however, be connected to your TV without a remote control.

Eco Mode Settings:

 Vizio Eco-mode features automatically turn off the soundbar if no audio signal is received. Smart devices consume a great deal of power nowadays, so the settings are very important. The automatic turn-off soundbar issue can be resolved by turning off the Eco mode settings.

Overheating of Your Device

The majority of smart electronic devices turn off if they are overheating and remain active for a long period of time. An overheating device can be caused by a malfunctioning cooling component or other internal problems. Vizio soundbars can shut off themselves if they experience overheating problems. It is necessary to dust your Vizio soundbar if it gets hot after a few minutes of use.

Read on to find out the five ways to fix this problem

#1: Check the cable connections

We’ll get started now.

Firstly, your Vizio soundbar may be powering on/off by itself for no reason…

The problem is that it is not connected to the correct ports on your device.

“What does that mean? ”

Say you have a TV hooked up to your soundbar.

The soundbar won’t detect audio signals if it’s not connected properly to the TV…

The device will automatically shut down.

It’s therefore important to make sure it’s connected to the right ports.

In accordance with Vizio, you should:

Step 1: Verify that the soundbar has an “Audio Out” input.

If your soundbar is hooked up to your TV…

It should be connected to the port marked “Audio Out”

Step 2: Ensure the soundbar is connected to the right input.

  1. Start by turning on your TV and selecting a channel.
  2. Make sure the TV is playing audio.
  3. Your soundbar’s input button should then be pressed.

Your soundbar will begin searching for audio inputs and flashing lights will appear.

The TV input will be detected until it detects the input.

Step 3: Let’s wait and see what happens.

Your soundbar seems to be working now, doesn’t it?

It’s good to hear that.

In the event that this is not the case, check to see if the issue is with your TV or the device you’ve connected to your soundbar.

The device will go into standby mode.

There are many benefits to doing this:

  • Increases battery life and conserves power.
