Vizio TV Turns On By Itself (Steps to Fix It)

It can be as infuriating as it is confusing when your Vizio TV just ups and turns on by itself for no apparent reason, but it’s a more common problem than you’d expect.

Fortunately, that means solutions for it are plentiful – here’s a few to remember:

  • Disable CEC on your Vizio TV
  • Ensure no other devices can cast content on your TV
  • Switch your Vizio TV to “Eco Mode”
  • Check for Internal Timers or Active Sensors

Following all of these steps should see you through the majority of causes behind the issue, and we’ll break them all down in better detail below.

Explaining How Vizio TV Turns On Randomly

CEC Mode Causing Automatic Boot-Ups

Your Vizio TV may have built-in features that cause it to turn on automatically. One common feature is Consumer Electronics Control (CEC). CEC allows devices connected via HDMI to control each other.

Sometimes, a connected device like a cable box or a gaming console might send a “Power On” signal to your TV.  

Here’s how you can disable that interaction:

  1. Navigate to the “Menu” on your TV.
  2. Select the “System” option.
  3. Choose “CEC”, then toggle the feature off.

Alternatively, you could also opt to enable “Eco Mode” on your Vizio TV to prevent it from randomly interacting with other devices altogether. It also has the added benefit of curbing overall power consumption.

Here’s how to set up “Eco Mode” on your Vizio TV:

  1. Navigate to the “Menu” on your TV.
  2. Select the “System” option.
  3. Tap “Power Mode” from the available choices.
  4. Select and enable “Eco Mode”.

Power Surges and Electrical Interferences

Power surges and electrical interferences can also cause your Vizio TV to turn on by itself. These surges can come from various sources, such as household appliances or weather-related events.

When a surge occurs, it can trigger the power circuit of your TV, leading it to turn on unexpectedly. Using a surge protector can mitigate this problem. This device will absorb excess electricity and prevent it from compromising your TV.

Additionally, ensure that your TV’s power cable and outlet are in good condition, as faulty wiring can also be a culprit – especially if your TV’s power flickers.

Consider Active Timers or Sensors

If the problem wasn’t resolved by the above quick

To get to the root of a Vizio TV turning on by itself, you may need to consider the internal timers, sensors, software issues, and necessary firmware updates.

Evaluating Internal Timers and Sensors

Internal timers can sometimes cause a TV to boot up unexpectedly.

Here’s how to check:

  1. Access the “Menu” on your TV.
  2. Navigate to “Timers”.
  3. Check for any running timers.

Note that the majority of running timers won’t persist after a shutdown.

Additionally, there’s also a chance that your Vizio TV has ambient light sensors. This nifty feature is meant to adjust the screen display with relation to room lighting, but might malfunction and cause your screen to flare or even boot up abruptly.

You should be able to find this within the “System” setting in your menu, though the exact placement – and even specific name – differs greatly between models. Be sure to check your user manual to find the right setting.
