Why Is My Vizio TV Component Input Not Working?

If your Vizio TV component input not working and you are looking for a reliable solution to fix the issue, then you’ve come across the right post!

Many users have reported that issue, so in this guide, we are going to shine some light and reveal the most effective methods to tackle the problem.

The Vizio TV component input may not be working if the input settings aren’t chosen correctly. Other possibilities are a faulty input port, bad cables, possible hardware damage within your device, or a power malfunction.

Before troubleshooting, we will get everything clear so you could get a better understanding of why your component input does not work.

Why Is Vizio Component Input Not Working?

Users have suggested many causes for this malfunction. From irreversible hardware damage to faulty input settings or loose cables.

We made sure to briefly describe all causes and provide a solution for each further in the post.

1. Input Settings

If the input settings have not been configured correctly, there is a possibility that the slot won’t read your cable.

2. Faulty Or Loose Cable

Sometimes, the issue may not be with your component input, but with the cable connected to it. Many Vizio users don’t plug the cable all the way in, which could result in not working input.

3. Not Working Port

After mentioning the cables and the input settings, it is worthy to include the port.

Ports are usually damaged by ferocious interaction with them. Constant in and out could have impacted the input performance over time.

4. A/V Device

We figured that you are already using an A/V device, so keep in mind that the issue could be related to the external device you’re using. We suggest testing a different A/V if you have any concerns.

5. Power Malfunction

Sometimes the component input might be interrupted due to a bad power flow.

After a sudden power outage, for example, a short-circuit can happen with the device connected to that input, which will damage both of the instances.

Now that you know a little more about your issue, let’s proceed with the troubleshooting guideline and hopefully get rid of this issue once and for all!

How To Fix Vizio TV Component Input Not Working?

The methods below are designed to identify and solve the issue if it is not related to a faulty hardware component, excluding the input port.

Our recommendation is to apply the methods in numerical order for the best results.

Method #1 Change Input Settings

Many users report that they can’t change input on Vizio TV. The problem turns out to be that they are not doing it rightfully so here is how to change the input:

1. Press the Input button on the remote.
2. Use the arrows to select the input.
3. Press OK to confirm.
4. Input is now changed.

Once ready, you have to check if the settings are set to the A/V device point of connection. Otherwise, the input slot will be inactive, no matter what device you connect to it.

Secondly, press the input button on your Vizio remote. The input setting of audio devices must be configured to the input setting wherever your A/V device is connected to.

Lastly, ensure that the cables between your A/V device and Vizio TV are connected properly.

Once you got all this right, check if the component input works. If not, let’s have an inspection of your wiring, shall we?

Method #2 Check Cables

Now that you’ve configured the input settings, if the issue persists you can check the cables within your configuration.

Some of them are well-known to be crucial to your TV’s component input, so let’s check their functionality now.

Our best suggestion here is to disconnect everything and reconnect from scratch. Check everything first hand and make sure all cables are plugged are all the way in.

If you’ve tightened them up and the Vizio TV component input is still not working, some of the cables may be faulty.

There isn’t a way you can troubleshoot, except connecting them to another TV to see if it will work. If it does, lucky for you, if not, you would probably have to buy a new set of cables to use in your configuration.

Method #3 Power Cycle Vizio TV

Sometimes, after a power surge or sudden power outage, there could be strange things happening with your TV.

It may have constant outages and black screen, or some of its ports may stop working as it is in your case.

The only way to make sure your Vizio TV is clean of power issues is to power cycle it.

Here are the steps:

1. Turn your Vizio TV off.
2. Unplug the power adapter from the power source.
3. Wait for several minutes for the active electricity to drain.
4. Plug the power adapter back in.
5. Check if the issue is still there.

This is how to power cycle your Vizio TV and if the input is still not working, then you’re left with a few possible causes. Let’s take a look.

Method #4 Test Input Port

Sometimes, the port itself might be responsible for this inconvenient outage.

These ports are really delicate and if you plug and unplug cables furiously, you might have accidentally damaged them.

To justify this theory, we suggest applying pressure to the cable towards the input. Hold steady and test while pushing the cable towards the input slot.

Using some force try to move the cable back and forth, up and down to find if there is a comfortable spot at which the input would work.

This way you can identify if your port has stretched and it does not support an unsupported connection.

If it works while you’re applying pressure this definitely means that the input is damaged and requires attention. But if it is still not working, that does suggest that the port is working, there is no real way to be sure.

However, there is one more thing you can try, so let’s proceed.

Method #5 Check The A/V Device

It is obvious that if your A/V device ain’t working you can’t expect to receive any input. In that regard, we suggest testing your component input with another A/V device.

This way you will be able to find out for sure whether the port is faulty or the whole issue is with your device.

In case your component input does not work even with another A/V device then the last option you’ve got left is to contact Vizio customer service.

Don’t hesitate to share what you’ve tried so far so you can ease up the feedback.

Your Vizio TV component input might not be working because of a power failure, misconfigured or faulty connections, and a bad input port. On the other hand, we have the possibility of wrongfully configured settings, all of which can be easily set right.
