Why Red light Flashing On My Vizio Soundbar? Top 3 reasons for red light blinking

1. Wrong Settings – Unnoticeable but important factor

Whenever your soundbar isn’t fixed properly, and all the settings are disturbed, then it results in flashing white lights. This error mostly occurs when you’ve connected to another device recently, due to which the standard data fluctuates and concludes in this fault.

“Demo mode” can also be a reason behind the flashing of red lights on the soundbar. You can detect this problem when the LED lights brighten up from top to bottom and then reversely from bottom to top.

The audio input settings matter a lot in the flawless working of the soundbar because a little error in this section can cause sound loss. 

To verify this fault, The input system of the Vizio soundbar starts to analyze every portion inside the soundbar, and while checking it flashes different lights at that specific location.

Quick Fixations (Very Easy-To-Use)

  • If you aren’t getting any sound from the soundbar and some lights start to blink on it, Then “Reset” your devices and ensure that the leads are seated properly. 

Checking the firm connection of cables can also help you when the subwoofer is connected via leads.

If you are using “Analog Cables (red and white cords),” then check whether they are plugged in “Audio Out Ports.”

Meanwhile, hold and press the “Power Button” on the soundbar for almost 5 seconds.

This procedure will allow the LED indicators on the front of the soundbar will blink three times; Mark that this indication may vary from model to model of Vizio Soundbar.

  • Also, adjusting the Demo Mode of the home theater Vizio soundbar. The purpose of this system is to regulate internal functioning; that’s why a little disturbance can result in an alarming sign.

  • If still lights are blinking, including the red light, Then try to reboot your soundbar because it’ll let the factory setup, and that’s why all the preferences will be cleared. 

Now you can adjust the settings perfectly and appropriately according to your mindset and the device’s requirements.
