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.

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.

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.
