I have a Vizio soundbar that keeps shutting off after a few seconds of continuous use. It cuts off for two, three, or even up to 20 seconds and then turns back on after that period. At this point, I’m not even sure what the problem is or how to fix it.
The situation is quite perplexing, and it is almost impossible to identify the source of the confusion. We can give you some recommendations to help you identify and resolve the issue, it’s possible, but we can’t guarantee that your soundbar will work as it did previously.
The following are a few possible solutions to your problem.
Best Solution for Vizio Sound Bar Cutting Out: Worked For Many People
It is most often when your soundbar is old or malfunctioning and becomes very hot while in use that you may experience sound cutting. You will notice that the temperature is rising higher than it was before.
The most effective approach to determine if this is the issue is to turn off your Vizio soundbar and allow it to cool before turning it back on. This time, the sound will continue to play for a longer period until it becomes unusable.
Vizio soundbars turn off the amplifier to safeguard the circuit board when necessary. Lights will flicker and react differently than normal to indicate that there is a problem. The remedy to this issue is to clean your soundbar thoroughly. There is something called dirt that is the primary cause of this issue.
Using compressed air, you may clean the soundbar to a certain extent by spraying it into the slots on the rear of the unit.
To thoroughly clean the soundbar, you will need to remove it from its case and thoroughly clean it. It will not become too hot when it has been cleaned, and the dust has been removed, and you will notice a huge difference.
Restart & Restore
If you are not having the issue mentioned above, but your soundbar is still experiencing sound cutting out, restarting and resetting your soundbar may benefit you. Restarting does not make a big difference; however, resetting the computer may resolve the problem if a setting causes the problem.
Change the source device.
Using a certain source device with your Vizio soundbar may also encounter this problem. For example, if your soundbar is linked to your television, connecting it to another device, such as your smartphone, might serve as a test and see whether the issue continues to occur.
Switch input method
It would be best if you experimented with different input options. It may or may not be a solution; however, there are situations when there is a hardware issue. It is possible that the connecting cable or television port has been damaged, resulting in the problem. By connecting another soundbar or similar device to the tv, you may verify that the cable and tv port are functioning properly.
Contact Vizio Support
When everything else fails, you may try one of the strategies outlined above, and you should contact Vizio support. You may expect them to supply you with a better solution or, if feasible, to replace the soundbar. In such an instance, they will provide you with more guidance on your specific model of Vizio soundbar.
If, after trying everything, your Vizio soundbar continues to cut out and you cannot resolve the issue, the only other option is to get a new best soundbar.
