Why Does Your Vizio TV Have No Signal?

Here are some of the most common reasons why your Vizio TV may be giving you a “No Signal” error message or not properly displaying the content you want to watch:

1. Issues With Cables or Ports

The most likely culprit for the troubles you’re having with your Vizio TV is issues with the cables connecting the input source to the TV.

This may be due to the HDMI or coaxial cable you’re using being damaged or frayed. It may also be a result of the port on your TV where you insert the cable being clogged up with dust

This prevents the cable from being able to establish a stable connection between your input device and your Vizio TV.

How to Fix it

Before you head to the store to buy a new cable or order one online, you should first make sure that it’s indeed the cause of the issue.

You can do so by using another cable you may have lying around the house, and seeing if the issue will be resolved.

Additionally, you can use an air blower to remove any dust that may have piled up in your TV’s ports.

If all this fails, only then should you go ahead and get a new cable.  

2. Mute Screen Feature Is On

Another possible reason why all you’re getting is a black screen when you turn on your Vizio TV is that you may have accidentally turned on the Mute Screen feature. This is a feature that stops your Vizio TV from displaying any video or audio temporarily.

How to Fix it

All you’ll need to do to fix this is disable the Mute Screen feature. You can do this by simply pressing and holding the Mute button on your Vizio TV remote for around five seconds. Once this time has elapsed, your TV will return to functioning normally.

3. Software Glitches

As with all smart devices, your Vizio TV depends almost entirely on its built-in software to function properly. Sometimes, this software may go haywire due to data overload.

How to Fix it

There are two ways you can go about fixing this issue. The first one is to power cycle your TV.

Here are the steps you’ll need to take to do so:

Unplug all external devices from your Vizio TV and then unplug the TV itself from the power source. Then wait for a few minutes and plug the TV back in and reconnect all your input devices to it

More often than not, that’ll give your TV the refresher it needs to fix any software issues it’s having.

Another method you can use to address your TV’s software issues is to give it a hard reset.

This is how you can do it:

When resetting your TV, you should also unplug all devices from it. Next, unplug your TV from the power source and press and hold the built-in power button on it for about 30 seconds

Now it’s time to reconnect all devices to your TV and plug it back in. the final step is to turn on your TV to complete the reset process.

Keep in mind that resetting your Vizio TV will result in any saved data, such as app login details being erased

4. Input Source Is Hidden

Another possible issue that may be causing your Vizio TV to not have a signal is that you’ve set the input source to be hidden. This is another feature of Vizio TVs that you may have turned on by accident.

This is no cause for concern and can easily be fixed. 

How to Fix it

In order to address this issue, you’re going to need to reconfigure your TV’s settings and unhide the input source in question.

Here’s how to do this:

The first step is to press the Menu button on your Vizio TV remote. In the settings menu that shows up, select System

If you can’t find it, it may be under the name Input Settings. A drop-down menu will show up from which you should locate the input source in question and select it

Finally, make sure that the Hide from Input List option is set as Visible.


If your Vizio TV has no signal, there are several issues that may be the cause of the problem. These issues can be categorized as hardware issues such as damaged cables or software issues.

These software issues include glitches, as well as, an incorrect configuration of your Vizio TV settings.
