Vizio TV No Antenna Input: Alternatives And Fixes!

Are TVs without built-in tuners actually TVs or mere displays? Well, Vizio calls them Tuner-less Theatre displays, and for a short time in their rich past, several Vizio TVs lacked a coaxial input!

The year was 2016, and Vizio had already established itself as a mainstay in the television industry. And so, like all eminent contenders, Vizio, too, started experimenting!

The result was a series of tuner-less TVs relying solely on the internet for content transmission. But the experiment was a failure, and it cost Vizio dearly.

To use an antenna with your Vizio TVs that lack a coaxial input, make use of an external tuner or an ATSC tuner box. Connect your antenna input into the tuner, and connect the tuner to your Vizio TV through the HDMI port.

Here's a more comprehensive guide on how to resolve issues with antenna inputs on a Vizio TV.

Before getting into the thick of things, first, you'll have to ensure that your Vizio TV does have a coaxial input to connect the antenna to or not.

Vizio, back in 2015 to 2016, came out with a lot of fascinating new features and products. Some were radical, others, not so much!

Among the radical ones include the introduction of SmartCast for newer Vizio TVs and OLED panels.

The lesser ones include the removal of tuners from their TVs.

Vizio TVs that came out between 2016-17 lacked tuners. The Vizio TVs that came under the purview of this exemption were the P-series and the M-series.

Some of the E series TVs, too, lacked tuners. These TVs were putatively named Tuner-less Theatre Displays.

Only the D-series Vizio TVs featured a traditional QAM tuner during this time.

If you still can't get a hold on the subject of whether your Vizio TV supports a tuner, all you have to do is to check the inputs on your TV.

An absence of a traditional F-type coaxial port indicates the lack of a tuner on your Vizio TV.

You may also find a more definite answer in the user manual of your TV.

If you do have a coaxial input and still can get the tuner to recognize the antenna, you have a relatively simple issue on your hand. Let's discuss this scenario in a later part of the article.

Now, let's look at how to get your antenna to work on a tuner-less, coaxial port negative Vizio TV:

Use an External Tuner on Vizio TV

If your Vizio TV doesn't feature a coaxial input, countervail this absence with an external tuner.

An external digital tuner works similarly to a TV tuner: connect an Antenna input into the tuner and scan for channels.

The only difference is that you'll have to connect the tuner to the TV via another input source, and most digital tuners connect to the TV via HDMI nowadays.

Now, external tuners come in all forms, sizes, and functions. Some of them even come with inbuilt antennas!

Others feature DVR capabilities and HDTV outputs.

Regardless of the type of digital tuners, only ensure that it supports coaxial inputs.

ATSC tuner boxes should do the job.

Advanced Television Systems Committee (ATSC) Tuners are capable of outputting HD content with minimal interference and transmission loss. They can receive and process both analog and digital signals.

Most TVs nowadays feature ATSC tuners built into them. You can also get external tuners that adhere to the working principle of ATSC standards.

Some of the best external digital convertor boxes available right now are:

  1. Mediasonic ATSC Digital Converter Box
  2. iView 3300STB ATSC Converter Box
  3. QFX CV-103 Digital Converter Box

Another great alternative to a traditional tuner and cable transmission is wireless transmission.

HDHomeRun is a prime example of wireless content transmission.

To make it work, plug the antenna input into the HDHomeRun box and connect it to a viable network. Ensure a snug cable fit to avoid issues like color problems on Vizio TV.

Install the HDHomeRun app on your TV and access your favorite channels wirelessly.

Check the Input Settings on Vizio TV

Coming to the other side of the coin, if your TV does have a coaxial port and still can't make the Antenna work, start by checking the inputs themselves.

Make sure you have connected the input to the coaxial port snug and tight. Slack connections can lead to black screen issues on your Vizio TV.

Next, ensure that you have switched to the corresponding input source on your Vizio TV.

Vizio TVs have a lot of input sources, and one can easily get overwhelmed with them.

If you can't get the source right, switch through all the input sources until you get a signal or a message informing you to set up the tuner.

If you don't come across either of these cases, it's only fair to surmise that the TV source you've been looking for might be hidden in your Vizio TV.

Here's how to fix such an issue:

Check for Hidden Sources

Check for Hidden Sources

Vizio has this uncanny feature that allows users to hide input sources.

As to the intent behind the feature can be various. An obvious reason would be to reduce the already copious number of input sources made available to you.

This feature can render the input source in question invisible to users.

If that's the case, you'll have to revert the preference for the hidden source back to visible.

Here's how to access the said feature on Vizio TVs:

1. Open the Menu tab on your TV.

2. Select the System option. On older models, select Input Settings.

3. CLick on the Hide input from list option.

4. Highlight the input in question (TV). Press OK to access the menu tab for the source.

5. Toggle ON the Visible option and exit the menu.

Check for the input source now on the Source menu.

Once you have access to the input source and can acquire a potent signal, proceed to configure the tuner to scan for regular channels on your Vizio TV.

Follow these steps to scan for channels on Vizio TV:

1. Open the Menu tab and select the Channels/Tuner setting option.

2. Click on Find Channel/Auto Channel Scan to run a scan for channels.

Check the Antenna Cables Connected to Vizio TV

The condition of the Coaxial cable plays a crucial role in signal transmission.

A worn-out cable with extensive damage to the cable insulation and ports can severely affect the transmission; even render the transmission void.

Check your coaxial cable for obvious physical damages like wear and tear, chaffs, and corrosion.

Corrosion and rust on cable ends may warrant a cable replacement nonetheless.

While in the process, you may also want to check the ports on your TV and antenna. Capricious weather conditions can corrode Antenna ports in due time.

Cable transmission can also get affected by interference induced by both internal and external elements.

Cable length, cable type, and transmission elements like Splitters and Extenders can all introduce interference.

Try to avoid using Splitters, and make sure to use either RG6 or RG11 coax cables for HDTV applications.

Update Vizio TV

Update Vizio TV

Now, with the hard stuff taken care of, let's talk about bugs and errors and how they can ruin your TV.

Bugs can enter your Vizio TV through various means, take hold of the system and cause all sorts of trouble, including disrupting the input recognition process.

And one means by which malicious files can enter your Vizio TV is in the absence of proper updates.

Outdated firmware has weaker security protocols and fails to hold up against inherent and extraneous issues.

The answer to such a mishap is to check and update your TV. Vizio, since the introduction of SmartCast, has made regular updates mandatory.

Follow these steps to update your Vizio TV:

1. Open the Menu tab and select the System option.

2. Scroll down and select the Check for Updates option.

Run a check and update your TV. Restart the TV and check for the issue now.

When dealing with issues on your Vizio TV, better Power cycle it as a mode of refreshing the TV.

A power cycle test not only refreshes the Tv but also drains any static charges from the system that tend to pile up in time.

Start the process by plugging out all the cables connected to the TV. Leave it idle for some time.

Then, press and hold the Power button for a few seconds. Repeat this step a couple of times.

Plug back in the cables and power ON the TV.

Factory Reset Vizio TV

Factory Reset Vizio TV

A hard reset pretty much sums up most troubleshooting procedures associated with the modern-day gadget.

Antenna input issues may arise from malicious files interfering with the system or due to some unpremeditated change of settings.

Either way, a factory reset can revert the system preferences back to their factory state.

In due process, a factory reset will also remove any and all unwanted files, errors, and bugs, giving you a clean slate.

To perform a factory reset on your Vizio TV, follow these steps:

1. Open the Menu tab and click on the System option. (Help on older models)

2. Select the Reset and Admin option.

3. Click on the Reset TV to Factory Defaults tile.

4. Enter the Parental Control Code. (Enter 0000 if not set)

Perform the factory reset and reconfigure the Vizio TV to your liking.

Final Thoughts

And there you have it, a comprehensive guide on antenna input issues on Vizio TV.
