In this guide, you’ll learn how to fix a Vizio TV that says no signal.
If you’re welcomed with a “No Signal” screen when you turn on your Vizio TV, there are a few things that might have caused this issue.
From my experience with using a smart TV for some years, I know that the main causes of a TV showing no signal are either the wrong input, a faulty or not tightly connected HDMI cable, or the current input source being hidden.
You can fix the “No Signal” error on Vizio TV by ensuring cables are not faulty and are firmly connected, and also by confirming you’re on the correct input. In most cases, you’ll need to check if your input source is hidden in your TV settings.
In the following sections, I’ll go over the solutions to fix the “No Signal” error on your Vizio TV in greater detail.
How to Fix a Vizio TV That Says No Signal
Check the Cable Connections to your Vizio TV
The first thing you’ll want to do is ensure that the cables going from your input device to your Vizio TV are not faulty and are firmly connected.
You’ll get a “No Signal” error if the TV is unable to connect to your input device, even if you have selected the correct input.
You should inspect the cables for signs of fault like an opening or burn. Also, make sure that the cables are connected firmly.
Don’t forget to turn on your input device and also connect it to a power source if external power is needed for it to work.
Check the Current Input on your Vizio TV
Another reason why you’re getting the “No Signal” error message is because you have selected the wrong input on your Vizio TV.
To fix this, you’ll need to switch to the correct input. If you don’t know the correct input you’re connected to, you can check the back of your Vizio TV to see if it is Comp, HDMI 1, HDMI 2, etc.
You can use the input button on your TV’s remote to switch to a different input.
Check if Input is Hidden on Vizio TV
You might be getting the “No Signal” message on your TV because your input source is hidden.
You can know when your input source is hidden if it is not included when you click the input button on the remote. Luckily, you can unhide an input source after it has been hidden.
Follow the steps below to unhide your input source:
- First, press the Menu button on your Vizio TV remote.
- Next, select System, and scroll to the input you’re connected to.
- Finally, select the Hide Input from List option and make sure the input is set to visible.
Power Cycle your Vizio TV
Performing a power cycle can help fix the “No Signal” message on your TV since it clears active memory.
In order to perform a power cycle on your Vizio TV, you’ll need to turn it off, disconnect it from the power outlet, and then proceed to carefully remove all the cables connected to it.
Then, reconnect the cables and plug the TV back into the power outlet after waiting for up to two minutes.
Contact Vizio Support
If you have tried the troubleshooting steps and nothing seems to fix the “no signal” issue, then you should consider contacting an expert.
You can contact Vizio Customer Support for help from a technician that can solve issues with your TV. It shouldn’t cost too much if your warranty is still available.
With the troubleshooting steps above, you should be able to fix the “No Signal” message on your Vizio TV.
Here’s what to do if your TV is showing a “No Signal” error message:
- Check the Cable Connections to your Vizio TV
- Check the Current Input on your Vizio TV
- Check if Input is Hidden on Vizio TV
- Power Cycle your Vizio TV
