Fix: Vizio TV turns ON then OFF after a few seconds

1. Ensure proper ventilation

In most cases, the TV turns on and off by itself because it has overheated. This can happen for several reasons:

  • Dust has blocked the slits at the back.
  • The TV has been running for too long.
  • The TV’s placement doesn’t allow heat to dissipate properly.

The solution is simple. Start by checking for and cleaning any accumulated dust on the TV. Then, ensure that the TV rests for at least 10 minutes after being used for a couple of hours.

Lastly, try changing your Vizio TV’s position to ensure proper ventilation. Do not place any other devices near the TV.

2. Check the power cables

If the cable supplying power to the TV is damaged or not working properly, your TV may experience issues such as turning on and off every 3 to 5 seconds.

Check the cable for any physical damage. If the cable appears fine, ensure that the connection with the power board is secure.

3. Check if the TV remote is working fine

If your Vizio TV remote with IR blaster is malfunctioning, it can cause your TV to turn off at random.

So, to make sure that your TV isn’t turning off due to a faulty remote, remove the batteries of your remote. Also, remove any other remotes you have.

Do this when your TV is still turned on. If the TV still switches off after a few seconds, likely, your remote is likely not the problem.

Also, check if the remote power button is jammed, clean it with a cotton earbud, and check whether the TV is working fine or not.

4. Disable HDMI-CEC Feature

You can disable the HDMI-CEC feature if the device connected through HDMI from your Vizio TV is causing it to turn off and on.

Unplug the devices connected through HDMI one-by-one to identify the device causing the issues.

And if your TV is not turning off and on continuously, you can disable the feature from the Settings as well.

To disable HDMI-CEC on your Vizio TV:

  1. Press the Menu button on your Vizio remote.
  2. Navigate to “System” or “Settings.”
  3. Look for “CEC” or a similarly named setting and select it.
  4. Set the HDMI-CEC feature to Off.

5. Power cycle method

Vizio TV updates on its own and there is a high probability of bugs entering your device. If that’s the case with your TV, this method will help you rectify it. This will help your television refresh and start again. Follow these steps to do the same.

  • Step 1: Turn off the TV
