Vizio TV Flashing Different Colors: How to Fix [2022]

When my Vizio TV started flashing various colors on the screen, I went online and read through Reddit and VIZIO forums to seek some internet wisdom, only to realize this issue is a bit more common than I initially expected.

So with some deep knowledge about the topic in my arsenal, I decided to write this one-stop troubleshooting article on how to fix the issue.

If your VIZIO TV is flashing different colors on a periodic basis, turn off service mode. If you still face issues, check the cables and the hardware for wear and tear and perform a power cycle. If all else fails, do a system reset and contact VIZIO support.

Turn Off Purity Check or Service Mode

Turn Off Purity Check or Service Mode

The service mode or Purity check is a mode that exists on almost all TVs of reputable brands that are usually sold in offline stores.

Such a mode exists to gauge the various colors the VIZIO TV's display panel can produce and acts as a feature to entice customers.

The service mode also defaults to flashing colors on a periodic basis in order to check how each color is rendered, helping VIZIO technicians to rectify color issues.

That being said, only select models of VIZIO TV have access to this option right from the user viewable menu, and other models rely on using key codes for access.

There are various ways to trigger this Purity check mode, and each method requires a VIZIO remote to be paired to the TV in order to input codes.

Check Cables and Specifications

Check Cables and Specifications

The condition of the cables connecting to your VIZIO TV can impact the digital signals and in turn affect your viewing experience drastically.

Cables act like lifelines to the whole Television multimedia experience, and a slight rupture or block in its communication channel can break the flow of operations.

This is most commonly noticed on VIZIO TVs that have withstood quite the test of time and environmental conditions.

If there are any ruptures in the cable or the body of the VIZIO TV, the chances of dust settling inside the systems get higher over time.

If such a crack exists on your VIZIO TV, best to get it checked with VIZIO technicians as soon as possible and find a way to patch it up if possible.

Check all the cables connecting to the VIZIO TV for any significant cases of wear and tear that can cause issues with the communication of signals.

If you notice any red flags, change the cables immediately, preferably from VIZIO itself.

If you prefer to buy cables from a third-party provider, always check the specifications of the cable and whether the VIZIO TV can support them.

If the cables, especially HDMI, don't match the specifications you require to watch media on your VIZIO TV, the media simply won't play or play at a degraded quality.

It is always recommended to get cables from a reputed seller like Amazon and from a trusted well-known brand with good customer ratings.

Power Cycle the Vizio TV

Power Cycle the Vizio TV

A power cycle can do wonders to the internal electronics of any device, including your VIZIO TV.

In fact, it is one of the most recommended troubleshooting steps by VIZIO technicians when it comes to fixing bugs such as VIZIO TVs restarting and Vizio TV tuner not working.

A power cycle, quite contrary to its rather intimidating name is something that most of us have performed to an extent, being a reboot of sorts.

But a proper power cycle acts as a reboot for the hardware components, instead of just the software.

Once performed correctly, it can help in rectifying any misbehaving charges within the system and instead charge the system as even as required for best performance.

To perform a hardware reboot or power cycle on your VIZIO TV, you can simply follow the steps below:

  • Unplug your VIZIO TV from the power socket.
  • Let the TV sit idle powered off for about a minute.
  • During the minute-long wait, long-press the buttons on the TV for about 10 seconds.
  • Plug your VIZIO TV back into the power socket.
  • Let the TV sit idle powered on for about a minute.

This safe power cycles your VIZIO TV.

System Reset the Vizio TV

As a last resort step, a system reset can help in restoring all the settings of your VIZIO TV, thus making sure the system stays clean from any software mishaps.

A system reset or a factory reset also cleans out any software bugs that might have latched onto the system from any of its daily functioning processes.

Do note that this will definitely wipe out all existing data on your VIZIO TV, and will reset your system to just like when you first bought the device.

To perform a system reset on your VIZIO TV, you can simply follow the steps below:

  • Using your VIZIO TV remote controller, press the menu button to open the menu on your VIZIO TV.
  • Navigate to the System option on the VIZIO TV using the remote controller.
  • Select the Reset & Admin option.
  • Select the Reset TV to Factory Defaults option and confirm your selection.

This will safely reset your VIZIO TV back to its factory defaults.
