Why does my Vizio television keep blinking?
Your Vizio television’s backlight is malfunctioning, causing it to flicker continuously. One or more of the LEDs in the backlight may be faulty. To remedy this, navigate to the Picture Settings on your Vizio TV. And reduce the level of backlighting. If this does not resolve the issue, you may need to replace the backlight strips on your television.
Vizio TV flickering on and off: nine solutions
1: Perform a power cycle on your Vizio television.
If your Vizio TV is flashing on and off, the issue is likely related to the backlight.
However, this does not necessarily indicate that the LED lights are faulty. It’s also possible that some lights are simply malfunctioning.
Therefore, it’s best to power cycle your Vizio TV first.
Essentially, you must restart the television.
And it is typically effective at resolving many of Vizio’s problems. Whether or not an app like Hulu is malfunctioning. Or an issue with a flickering screen.
It is also very simple to accomplish. It should take barely a minute or two.
The quickest method is to unplug the device.
How to cycle power by unplugging
- Disconnect the power cord from the outlet on your Vizio television.
- Press and hold the TV’s power button for approximately thirty seconds.
- Reconnect your television to its power source.
- To restart the device, press the power button.
In addition to unplugging, certain Vizio televisions have an option for a soft power cycle. Where the TV can be restarted via the system menu.
How to execute a soft power cycle
- Press the Menu button on the Vizio remote control.
- Scroll down and select the System option.
- Select Reset & Admin from the menu.
- Choose Soft Power Cycle
2: Check for power source problems
Now there is a possibility that your Vizio TV is functioning properly. However, the power source is creating the flickering.
A malfunctioning plug or surge protector, for instance, may cause the TV’s power to vary. And this may be the reason why it turns on and off.
Try connecting your television to a different power source.
Unplug your television from a power strip if you are using one. Instead, attach it to a wall outlet.
In addition, inspect the power cord of your Vizio television for damage. If so, search for a replacement cable.
Also, ensure that it is securely attached to the television.
You may also try disconnecting the TV’s cord. Afterwards, rejoin. Additionally, attempt to wiggle it to check its attachment is secure.
3: Test the remote for defects
You could not rule out a defective remote if the screen was blinking or flickering.
There are numerous options for this.
One possibility is that the power button on your remote is jammed. Probably as a result of trapped dust or other minute particles.
Another possibility is that the remote’s battery is low.
Apparently, when its batteries are faulty, a remote will occasionally transmit odd signals.
Try removing the remote’s battery. If your television stops flashing, the problem is likely with the remote.
Then, begin by cleaning the power button. This is to prevent it from becoming trapped.
After that, batteries should be replaced. Vizio TV remotes normally need 2 AAA batteries.
4: Reset your Vizio television’s Picture Settings
Since a blinking display is typically caused by the backlight…
You must make various tweaks to the Picture Settings on your Vizio.
In certain instances, though, resetting the entire Picture Settings is sufficient. You will not require access to the advanced menu settings.
Now, resetting Picture Settings is equivalent to a factory reset. However, only for image-related options. Therefore, all other information should remain untouched.
However, you should attempt to do so before making any further adjustments.
The steps are as follows:
- Press the Menu button on the remote control.
- Navigate to Picture and push the OK button on the remote control.
- Navigate to More and press the right arrow on the remote.
- Select Reset Picture Mode.
Click Reset to confirm your choice.
This was sufficient for many users to stop their Vizio television from flashing.
5: Select a Picture Mode with a low backlight sensitivity
Your Vizio television features multiple Picture Mode settings. Including:
- Dark Calibrated
Each of them varies in terms of backlight intensity, luminance, and contrast.
If you think that one or more of your television’s LED bulbs are defective…
Select a low lighting level Picture Mode. Ideally, 65 or less. You’ll see it under each mode.
Standard, Calibrated Dark, and Game modes all have low backlight levels. So you may choose from any of those.
- Press the Menu button on your Vizio remote.
- Highlight Picture and press OK.
- Highlight Picture Mode.
- Select Standard, Calibrated Dark, or Game by using the remote’s arrow.
Now, if you’d prefer another mode, that’s fine. As long as you adjust the backlight level.
Just scroll down under the Picture Mode. Then, highlight Backlight. And press your remote’s Down Arrow to decrease its level to 65 or lower.
Here’s a video demonstrating how adjusting the Picture Mode can fix a flickering screen:
6: Switch off Ambient Light Sensor and Adaptive Luma
Ambient Light Sensor is a feature that automatically adjusts a device’s brightness.
If the environment’s too dark, it automatically brightens the screen. And the opposite if a place is already well-lit.
It’s a feature that’s on many modern smart TVs and smartphones.
Adaptive Luma is similar. It also automatically adjusts the brightness and contrast of your screen.
You can find both of these features on your Vizio TV. And both of them affect your TV’s backlight.
That’s why it’s best to switch them off if your screen’s blinking screen.
How to switch off Ambient Light Sensor and Adaptive Luma
- Click your Vizio TV Menu button.
- Go to Picture and select it.
- Toggle the Picture Mode to Custom.
- Select More.
- Navigate to Advanced Picture and click it.
- Select Adaptive Luma.
- Press the remote’s arrow button to toggle it off.
- Scroll down to Ambient Light Sensor.
- Switch it off by clicking the arrow button.
7: Check for external device issues
There are also cases where the external devices are the ones causing the TV to blink.
Nowadays, HDMI is the most used cable for connecting devices to TVs. And it’s mainly because it’s excellent at transmitting both audio and video.
So if it’s old or defective, it’ll likely cause picture or audio problems on your TV.
Vizio recommends using HDMI 2.0 or newer cables to avoid a flickering screen.
And aside from the HDMI cable, the external devices themselves may have issues.
So if you have any of the following connected to your Vizio TV:
- Gaming Console.
- Streaming Player.
Try to disconnect them from the TV. And check if the blinking stops.
8: Update your Vizio TV’s firmware
While not always the case, there are instances where an OS glitch can cause a blinking screen.
So it’s also important to keep your Vizio’s SmartCast OS up to date.
Your TV will download updates in the background if there are available ones. It’ll then install the updates when you power it off.
But you may also manually check for updates. It’s ideal to do this if your TV’s been offline for a while. And you believe you’ve missed out on updates.
You can update your device via these steps:
- Click your Vizio remote’s Menu button.
- Navigate to System Option and select it.
- Select Check for Updates.
9: Factory reset your Vizio TV
So you’ve reset the Picture Settings. You’ve also switched off various advanced features.
And even installed the latest firmware.
But your Vizio TV screen’s still blinking.
At this point, you may have to do a factory reset.
This is normally one of my last recommendations because it’ll wipe out your entire data. So you’ll basically have to start over again with your Vizio TV.
But it’s also an effective fix.
So here’s how to factory reset your Vizio TV:
- Grab your Vizio remote and click Menu.
- Go to System and click it.
- Scroll down to Reset & Admin and select it.
- Select Reset TV to Factory Defaults.
- Enter your password. If none, type in 0000.
- Click Reset.
Your TV will then begin the factory reset process. This should take several minutes. So just make sure to keep your TV on.

If the fixes don’t work, then there’s likely severe damage to the LED backlight.
You may actually try to fix them yourself.
Just remove the back cover of your TV. And then replace the backlight strips with new ones.
However, not everyone may be comfortable doing that. So it’s best to leave it to the hands of an expert.
