A blinking screen on your Vizio TV could be caused by some problems, but it will ultimately result in an unpleasant viewing experience for you and your family.
Your blinking screen could be caused by a bad cable signal, a malfunction in one of the devices connected to your TV, or the earliest sign of internal hardware breakdown.
A defective backlight, a loose or malfunctioning video cable or port, inadequate signal strength, or incorrect display settings can cause a Vizio TV flickering.
When the firmware is faulty, the TV logo will flash, and the power light will blink if an update is required or if you are using a foreign remote.
Why is your Vizio TV Flickering
When you start watching your favorite show, and suddenly your TV starts flickering, and unfortunately, you are not aware of the reason why your Vizio TV is flickering, and because of that, it becomes difficult for you to find a solution for this problem.
So here are some reasons which can cause your Vizio TV to flicker.
1. Backlight Failure
LCD panels cannot self-illuminate and therefore rely on a third-party backlight to enhance the colors created by liquid crystals.
Before your backlight entirely burns out, it will exhibit warning indications like as flickering, flashing, a pinkish tinge, and dimming.
Even if your backlight is dead or failing, the liquid crystals will continue to create their colors.
Flashing a flashlight at a 45-degree angle allows you to see those colors, indicating that the screen itself is still operational but that the backlight is insufficient to illuminate them.
2. Internet Connection
A poorly connected cable, whether a power wire or a coaxial cable, might cause a flickering screen.
Check the power cord and cable output connections on the bottom rear of your VIZIO TV.
The connections must be secure, and the wires that extend from them must be free of damage, including crimped or frayed sections.
3. Problem with the signal
A faulty signal can cause a screen to flicker or flash, as well as a variety of audio and visual issues such as distorted audio, pixelation, and freeze frames.
Check that your satellite dish is properly positioned to receive the greatest possible signal.
4. Failure of an Inverter
Inverter failure might potentially cause the screen on your Vizio TV to flicker.
The master inverter on the VIZIO provides a consistent source of energy to the TV, while the slave inverter lights the lamp.
If either of these inverters fails, sufficient electricity will not reach the backlight. To test the inverter board, carefully remove your TV’s back panel with a screwdriver and set it away.
5. Wrong picture settings
The brighter areas of a photograph are affected by the contrast setting; if the contrast is set too high, you could lose information in bright reflections or white backgrounds.
On the other hand, a TV’s brightness slider is used to adjust the picture’s darker tones. If Brightness is too low, shadow detail will be lost, and this can cause a flicker in your TV.
Vizio TV Flickering
You must reset it if your Vizio TV is flickering. Unplug your television and wait 60 seconds. Press and hold the power button for 30 seconds while the TV is unplugged. After 60 seconds, reconnect your Vizio TV, and the flashing should stop.
Unplug Vizio TV from the wall
One of the most common causes of a Vizio TV flickering is a loose power connection. Check that the power connection on both ends is secure.
Step 1: Unplug the power cord from the tv (if it’s removable)
Step 2: Take the power cord out of the wall outlet.
Step 3: Reconnect it after 60 secs.
When you connect the TV back in after 60 seconds, it should power up normally, and your screen should no longer be flickering!
If you do this and your TV still does not operate properly, check to see if electricity is coming from your wall outlet.
Find a device that can be plugged into the same electrical socket to confirm that it is powered. If the outlet is turned on, but your Vizio TV is still not working properly, you should power cycle it.
Adjust Picture Settings on Vizio TV
The problem of your Vizio TV flickering on and off is frequently related to your TV’s visual settings. The first thing you should attempt is to reset the camera’s photo mode.
Your television may have a picture mode that is best suited for a line cook but is not suitable for a room. This could be one of the reasons for your Vizio TV’s poor visual presentation. To resolve this, follow the steps outlined below.
- On your remote control, press the menu button.
- Scroll down to the photo mode option and select it.
- Finally, try the various picture modes to find which one works best for you.
You can go further if you are an expert or have some knowledge of how TV visual settings work. Users can improve the display by adjusting the Vizio TV’s picture mode, which has several settings.
You can also change the Backlight, Brightness, Contrast, and other settings. Pick a tv setting, navigate to the picture setting, and then select custom and change on your remote.
Hopefully, you’ll discover one that solves your issue.
Disable the Clear Action feature
It’s a feature that attempts to eliminate motion blur. This is fantastic for viewing sports. Or those high-octane action films with lots of chasing and running.
It’s also a function found on the majority of current smart TVs.
Clear Action, on the other hand, does not always perform effectively with Vizio TVs. Indeed, many users have expressed dissatisfaction with how flaky this feature may be at times.
It can also cause a flickering screen when it is glitching. As a result, you should disable this option as well.
The steps are as follows:
- On your remote, press the Menu button.
- Choose Image.
- Scroll down and select More Picture.
- Choose Clear Action.
- Click the Off button.
Switch off the Advanced Picture options
Your flickering screen should be resolved by adjusting the Picture Mode and deactivating Clear Action.
However, if your television still has that problem, you’d have to select Advanced Picture. Also, turn off two settings in particular:
- Black detail
- Backlight control
Black Detail modifies the average brightness of your television.
Backlight Control, on the other hand, auto-calibrates the TV’s contrast ratio. As a result, the brightness has increased. And the darkness is much darker.
Both characteristics can help to improve image quality. They can, however, put a lot of strain on the backlight.
When your backlight fails, it’s best to turn it off.
Here’s how it’s done:
- Press the Menu button on the remote.
- Choose Image.
- Select Advanced Picture and click it.
- Control of the highlight backlight.
- To turn it off, press the arrow on your remote.
- Highlight the Black Detail by scrolling down.
- To turn it off, use the arrow button on the remote.
Check for faulty ports and Cables
A defective cable is another potential reason for a flickering screen.
HDMI cables, in particular, can be difficult to work with at times.
So, if you’re utilizing one, look for flaws.
Also, try to clean it by removing any accumulated dust or debris. You can do this with a cleaning brush.
Also, make sure you’re using a newer version of the HDMI cable.
Vizio recommends versions 2.0 and 2.1.
It’s also possible that the screen flickers are caused by a faulty port.
Vizio TVs have at least four HDMI ports. So try plugging your external device into a different one of those. Just make sure to change the input setting on your television.
Temporarily disconnect all external Devices
In rare circumstances, the flickering screen is not caused by the television. Or perhaps the cables and ports.
It is caused by an external device.
So unplugging all of your TV’s external devices is an easy method to find out.
After that, restart the television.
Is the flickering gone? If this is the case, the issue is most likely with the device you’ve linked to it.
So, whether it’s a game console or a media player…
Look for any settings that could be causing image problems. Also, be certain that it is free of any damage or flaws.
You can also quickly reset it by disconnecting it from the power source.
Change the Video Source
For example, flickering can occur when your TV receives damaged frames from a streaming broadcast.
At the absolute least, this step will assist you in determining whether the problem is with your Vizio TV or something else (like your Firestick, Roku, or other connected, streaming device).
Inspect all connections
Look for any loose connections, bent cables, or damaged cords.
If you notice that the flickering only occurs when your TV is connected to a specific input, this is a major indicator as to which connections are malfunctioning.
For example, if your TV only flickers while you’re playing a video game, you should check all of the console’s cords.
HDMI wires, in particular, are infamous for generating issues. There are several types of bad HDMI connections:
- Loose HDMI connection
- Faulty HDMI port
- Bad HDMI cable
If unplugging and reconnecting the TV did not resolve the flickering, you should:
- Try connecting your TV to a different HDMI port.
- Attempt a different HDMI cable.
If flickering occurs just when you use cable TV, you should inspect the wires connected to the cable box instead.
Fortunately, these wires are not expensive to replace these days.
Update Vizio TV OS
The most recent software and firmware updates should always be applied to TVs. These updates come with important applications, feature upgrades, bug patches, and vital features.
If your Vizio TV’s software is out of date, it might cause a slew of problems. Simply check for new Vizio TV OS updates to resolve this issue.
All you have to do is check for the most recent firmware update for your TV model. These updates are usually performed automatically, but they are infrequently overlooked.
To update the firmware on your Vizio TV, switch it on and press the “Menu” button on your remote. Then scroll down and choose “System.”
Click on “Check for Updates” if you see it.
Your TV will immediately begin searching for any available upgrades. If a new one becomes available, your TV will install for you.
To keep up with the latest software, make sure you update your Vizio TV frequently!
Factory reset Vizio TV
If updating the operating system didn’t address your flickering issues, it’s time for a full factory reset.
Click the Menu button with the TV turned on (ideally, disconnecting it or removing the remote batteries was able to temporarily power the TV).
There should be a “System” option in the menu; select it.
Then look for “Reset & Admin” and “Reset TV to Factory Defaults.” Before resetting the Vizio TV, it may prompt you for a code. If it does, the default code is 0000, which is four zeros.
This will essentially return your Vizio TV to the settings it had on the day you bought it.
Factory reset Vizio TV without Remote
If you don’t have access to your TV’s remote for some reason, you can still factory reset your Vizio TV.
To do so, locate the power button on your Vizio television. Depending on the model, this may be located on the right, left, or very bottom of the device.
With the TV turned on, simultaneously press and hold the volume down and Input buttons. Your TV will prompt you to press and hold the input button after a few seconds.
For at least 10 seconds, press and hold the input button.
This will turn off the TV, reboot it, and perform a factory reset. The reboot and reset procedure can take up to a minute.
You should have entirely cured your flickering difficulties by this time, but just in case, I’ve added a few further steps worth trying before calling it quits.
Consider the lighting in the room
TV screens, believe it or not, are always flashing. But it usually happens so quickly that you can’t tell in normal circumstances!
However, certain severe lighting circumstances might make these refresh rates visible, giving the TV the appearance of flickering. Fix it by either brightening or darkening the room.
You can also try to resolve this issue by altering the brightness settings on your television.
This may require some trial and error, so stick with it for a while before going on.
Investigate internal hardware problems
You should attempt all of the other troubleshooting alternatives before concluding that this is the issue!
You are unlikely to be able to solve this type of problem on your own (unless you are a skilled professional). It’s generally better to take your TV in for repair or consider buying a replacement.
If this is a modern TV, it may still be covered under warranty!
Check Vizio TV Warranty
If you simply cannot get your Vizio TV to stop flickering, you should check to see if you have a current warranty on your TV.
After you describe the problem and Vizio determines whether or not it is covered under warranty, they will either repair or replace your TV.
They even provide in-home services if this is covered by your warranty. It’s worth a try!
Frequently Asked Questions
The TV will restart, and the Setup App procedure will begin. SmartCast TVs may also be reset by pushing and holding the input and volume down buttons on the TV’s side.
After 10-15 seconds, a banner will appear instructing you to press and hold the input button to restore the TV to factory settings.

How long does a Vizio TV last?
A Vizio TV will last you roughly 7 years on average, but with proper maintenance, you may prolong its life to up to 10 years.
It will last much longer if the owner properly cares for it, keeps the components up to date, and does not abuse the TV.
Vizio TVs are fantastic TVs that you can enjoy for a long time.
Is it worth repairing a VIZIO TV?
It is worthwhile to fix your television if the cost of repair is much less than the cost of purchasing a new television.
A cracked screen is frequently the most expensive repair for a flat-screen TV, costing more than a replacement TV for all but the largest screen sizes.
The national average for TV repairs is $100 to $300, with most customers spending around $200 to fix an inverter in an LED TV.
Why are Vizio TVs so cheap?
More specifically, companies like Vizio do not need to profit from every TV sold.
Smart TVs can be sold to consumers at or near cost because Vizio can monetize them through data collecting, advertising, and direct-to-consumer entertainment sales (movies, etc.).
Vizio’s larger televisions suffer from the same bad viewing angle issues, so you can’t see the screen clearly unless you sit directly in front of it.
So the reason they’re so inexpensive is that they only have a small screen. Also included are a sound card and speakers. As a result, Consumer Reports rates all Vizio televisions as having mediocre sound.
What’s the warranty on a VIZIO TV?
VIZIO warranties its products to the original purchaser for ninety (90) days of non-commercial usage against faults in materials and workmanship.
If a VIZIO product fails within the warranty period, VIZIO will repair or replace the equipment at its sole discretion.
Your new Vizio TV comes with a one-year manufacturer warranty, but it does not cover everything and is not very long.
With an extended TV warranty, many Vizio owners choose to expand and extend warranty coverage. It’s a terrific method to add peace of mind while keeping your electronics budget under control.
When it comes to flickering, Vizio TVs may be picky. If your Vizio TV is flickering, attempt the following remedies in the following order:
