Sometimes your Vizio TV may flash at you, whether it is the screen, logo or power light. There is usually a logical explanation for this, but sometimes it is hard to pinpoint exactly why it is flashing and how you can fix it. If you are experiencing this, this article contains a number of causes for a flashing Vizio TV, as well as solutions to fix it.
A Vizio TV will flicker if there is a broken backlight, loose or faulty video cable or port, poor signal strength or incompatible display settings. The TV logo will flash when the firmware is corrupt and the power light will blink when an update is required or if you are using a foreign remote.
These issues can be fixed using the methods I have outlined in this article. You will also find a number of settings on your TV that may have been causing you issues with flickering or blinking lights.
Vizio TV Keeps Flashing/Flickering
If your Vizio TV is flickering, it is most likely a malfunctioning backlight. You can test if the backlight is not working by shining a light on the screen. The LCD crystals will still produce their color, even if the backlight is broken, so the external light will make them visible again.
This will either be because the backlight has reached the end of its life, or because of a hardware malfunction. Either way, you will need a service technician to open the back of the TV to fix the problem or replace the hardware.
If this occurs under warranty, you may be issues with a new TV. However, if the screen is flickering black, it may be another issue which I will discuss below. If you are unsure, below are some general troubleshooting techniques that may fix your issue.
Hard Reset of the TV
A hard reset will clear any internal memory, including minor malfunctions, but it will not erase your settings or remove any downloaded content. You can do this with the following steps.
Step 1: Turn off your TV and all connected devices.
Step 2: Unplug the TV from the power.
Step 3: Press the power button on the TV for 30 seconds.
Step 4: Keep the TV unplugged for another 10 minutes.
Step 5: Plug the TV back in and turn it on.
Factory Reset
A factory reset will erase all saved preferences and delete any downloaded content on your TV. Therefore, you should only do this if you have tried everything else. Below are the steps involved in a factory reset.
Step 1: Press the ‘Menu’ button on the remote.
Step 2: Navigate to System > Reset & Admin.
Step 3: Select ‘Reset TV to Factory Defaults’.
Step 4: Enter your TV’s passcode, or the default code, ‘0000’.
Step 5: Select ‘Reset’ to confirm the factory reset.
Step 6: Wait for the TV to turn off and back on again.
Vizio TV Blinking On And Off
Sure, here is an introduction to an article on the topic of “vizio tv blinking on and off”:
Introduction
If your Vizio TV is blinking on and off, it can be a frustrating experience. There are a few reasons why this might happen, and it can be difficult to troubleshoot the issue. Here is a list of the most common causes of a Vizio TV blinking on and off.
- Check Power Source:
- Ensure the TV is properly connected to a stable power source.
- Verify that the power cord is securely plugged into both the TV and the outlet.
- Try a different power outlet or surge protector to rule out electrical issues.
- Remote Control Interference:
- Check for any nearby devices that might interfere with the TV’s remote signal, such as fluorescent lights or other remotes.
- Remove potential sources of interference to see if the blinking issue persists.
- Test Different Inputs:
- Connect the TV to different input sources (e.g., HDMI, AV, or USB) to determine if the issue is specific to a particular input.
- Firmware Update:
- Access the TV’s menu and check for available firmware updates.
- If an update is available, follow the instructions to install it. Outdated firmware can cause various issues, including blinking problems.
- Check Cables and Connections:
- Inspect all cables (HDMI, AV, etc.) connected to the TV for damage or loose connections.
- Replace any faulty cables or reconnect them securely.
- Factory Reset:
- Perform a factory reset to restore the TV to its default settings.
- Refer to the user manual or Vizio’s website for instructions on how to perform a factory reset for your specific model.
- External Devices:
- Disconnect all external devices (e.g., gaming consoles, Blu-ray players) from the TV and check if the blinking persists.
- Reconnect each device one by one to identify if a specific device is causing the issue.
- Contact Vizio Support:
- If the blinking problem continues despite following the troubleshooting steps, it’s best to reach out to Vizio’s customer support.
- Provide them with detailed information about the issue and the steps you’ve taken to resolve it.
Remember, some Vizio TVs have specific model-dependent issues, and the steps above are general guidelines. Always refer to the user manual for your specific model or contact Vizio support for personalized assistance.
Vizio TV Keeps Blinking Black
A black flickering screen usually indicates that the display settings are wrong or that the display signal is compromised. Below are ways you can fix these issues.
Re-Insert All Connections
The easiest way you could fix this is by unplugging all connections to the TV and re-inserting them. One of the cables may be loose, causing the video signal to cut in and out. Make sure you are pushing the connections all the way into the sockets.
Check the Cable and Port
It may also be that your cable is not working properly. Firstly, you should try the cable in a different port. That particular port may be malfunctioning.
If you are using a HDMI cable, try a different one to see if your original cable was faulty. You should make sure that you are using at least HDMI 2.0 as this will allow more information to pass through to the TV. Sometimes the screen is flickering because the TV is replacing the lost information with a blank screen.
Disable Advanced Video Settings
Many people have had issues with the TV’s Advanced Video Settings. These are designed to improve your TV display, but sometimes they can inhibit the video if the signal is not compatible. You can find these using the pathway below.
Menu > Advanced Video
Try disabling all of the following settings. If you prefer, you can try to isolate if one of these settings is causing the problem so that you can keep the others enabled.
· Ambient Lighting
· Backlight Control
· Advanced Adaptive Luma

Poor Cable Signal
A poor signal from your satellite TV will also cause a black flicker on your screen. You should align your satellite dish to ensure you are receiving the strongest signal possible. Then you can unplug your set-top box, wait a few minutes and then plug it back in to perform a hard reset.
Vizio TV Power Light Blinking
The Vizio TV power light is normally solid. However, some people have found that it will start blinking and sometimes even keep blinking after the TV has been turned off. This can be due to a number of reasons, outlined below.
One reported fix has been to change the admin settings to turn the power indicator on permanently. You can try this by following the pathway below.
Menu > System > Reset & Admin > Power Indicator > On
If this does not solve your issue, you can try the following methods.
Using the Vizio Remote
If you are using a remote other than the Vizio remote, such as an Xfinity remote, this will cause the light to flash. This is likely a bug in the firmware that may be in the process of being fixed.
Bugs are usually fixed in the latest firmware update on your TV. If you are unsure if your firmware is up to date, you can check this manually, which I will detail below. In the meantime, using the Vizio remote should stop the light from blinking.
Update the Firmware on Your TV
You TV should automatically update its firmware when a new update is available. If you are aware of a new update but the TV has not downloaded it, you can update the firmware manually using the method below.
Menu > System > Check for Updates
If an update is available, you will be prompted to confirm that you want to install it. Keep in mind that some companies release their updates over a period of one or two weeks, so the update may not be available in your region yet.

Some people have found that the power light will also blink if an app needs to update, or was attempting to update. If this is the issue, you should ensure all apps on the TV are up to date as well. You can update apps using the steps below.
Step 1: Highlight the app you want to update.
Step 2: Press the yellow button on your Vizio remote.
Step 3: If an update is available, select ‘Update’.
