But, sit back and relax for a few minutes….. 

This article tells you about some basic reasons to detect the fault with your VIZIO Soundbar

Just have a look at these pointers and ponder upon the reasons very carefully. It might be a problem that can be rectified at home very easily.

Why My Vizio Sound Bar Turning off by itself?

Lets discuss all the reasons and fixes in detail.

1. Outdated Software

The soundbar’s firmware may be out of date. It might happen that the installed firmware on your soundbar is out of date and is under an urgent needs to be rectified. For this go on to the soundbar’s settings and there you will see ‘Recent updates available’. If any updates are available connect your soundbar to the internet and update the software as soon as possible.

2. ECO Settings

Check on your soundbar’s ‘Eco’ settings. It might happen that the Eco settings of your soundbar may not be pulled ON and you might be trying to operate it without knowing the real fact.

3. Remote Control Mismatch

There may be some mismatch between your remote and the soundbar connection. Please have a check on the remote you are using for controlling the soundbar. If you are using a remote of another brand then there might occur a problem that the soundbar may not respond to the commands you give to it via the remote control which may lead it to hang up abruptly.

4. Device Overuse

Device overheating is another problem that may have caused the soundbar to turn off on its own. This might have probably occurred due to device overuse. Sometimes watching a movie or playing music out of the soundbar for too long say 5-6 hours can cause the soundbar to function abnormally and ultimately may lead to its turning off.

5. Electrical Glitch

There might be some electrical glitch with your soundbar. The internal circuits may damage due to this. It usually happens when there is a sudden discharge of high voltage which breakers the soundbar’s fuse and can cause it to malfunction. So, always avoid connecting the soundbar to a DC supply.
