Watching and streaming videos on your Vizio TV can be a great way to relax and enjoy quality time. But when the TV keeps randomly restarting, it can become an annoying interruption.

Different things could cause the TV to keep restarting, but luckily there are solutions to fix it. So, if you are experiencing this problem, this article will cover all the causes and the solutions to help get your Vizio TV running smoothly again.

What Are The Causes Of Vizio TV To Keep Restarting?

There can be a variety of causes that could lead to your Vizio TV randomly restarting.

Some of the common causes include:

  • Firmware Issues: Firmware is the software that runs your TV; if it is not up to date, it can cause the TV to restart randomly.
  • Loose Cables: If the cables that connect your TV to other devices, such as your cable box or gaming console, are loose or disconnected, it can cause your TV to restart randomly.
  • Power Issues: Power issues or surges can also cause your Vizio TV to restart randomly. This is due to the TV’s inability to handle the sudden increase in power.
  • Overheating: This is a common issue with TVs placed in an enclosed area or direct sunlight, as it can cause the TV to overheat and restart.

Best Solutions To Fix Vizio TV Keeps Restarting

Fortunately, some easy solutions can help you fix this issue.

1. Update The Firmware

You should check to ensure you have the latest firmware update for your Vizio TV. An outdated or corrupted firmware can cause it to restart randomly. To update the firmware, open Settings from the Home screen and navigate to System> About.

Tap Check for Updates, and follow any on-screen instructions.

After updating the firmware, you should test to see if the issue is resolved.

2. Reboot The Device

Sometimes, the simplest solutions are the most effective. Rebooting your Vizio TV is a great way to fix many issues, including restarting, freezing, or slow response time. To reboot your Vizio TV, unplug the power cord from the outlet and wait a few minutes before plugging it back in.

Once the TV has restarted, you should notice a faster response time and fewer issues overall.

3. Broken Adapter Or Cable

It is essential to check the cables and adapter connected to your Vizio TV, as they are the main source of power. Over time, the cables or adaptor may get damaged, especially in the case of lightning strikes. If any of these components are broken or not functioning properly, your TV will restart frequently.

To confirm, try replacing the cables or adapter with a new one. If that solves the issue, you know the problem is with the cables or adapter. Make sure to use the proper cable and adapter for your Vizio TV, as using an incompatible one may cause further damage.

4. Overheating

In some cases, your Vizio TV may be restarted due to overheating. This can happen if the TV has been running for a long time and the internal components become too hot. To avoid this:

  • Ensure your TV is not placed in an area with limited airflow or direct sunlight.
  • Clear any blockage from the ventilation openings on the back and sides of the TV.
  • If your Vizio TV is still restarting due to overheating, consider investing in a cooling fan or using a vacuum cleaner to clean the dust from the vents. This should help to reduce the temperature inside your TV and prevent it from constantly restarting.

5. Check The Voltage

If your Vizio TV keeps restarting, it could be due to a power supply issue. Check the voltage of your outlet or power strip to ensure it provides the correct voltage for your television. You may need to use a different outlet with the correct voltage if it is too low.

You may need to invest in a voltage regulator or surge protector if it is too high. If the voltage is correct and your TV continues to restart, you may need to move on to the next steps.

6. Unplug Other Peripheral Devices

Peripheral devices such as DVD players, video game consoles, and cable boxes can interfere with your Vizio TV’s connection. If you’re experiencing random restarts, try unplugging any peripheral devices in the area. This will reduce interference and resolve the issue.

If this doesn’t work, you may need to move the peripheral devices away from your TV. However, if you’re still experiencing random restarts after unplugging the peripherals, you may need to look into other potential causes.
