3. Software Conflicts
Don’t you know that software conflicts can also cause the “No signal” error? Yes, you heard it right. In some cases, the software conflicts prevent the device from getting a proper signal. For that case, you have an option to soft reset your Vizio Smart TV to get the proper signal back.
4. Hardware Issues
You can encounter “No signal” error on the Smart TV, if your TV has hardware issues like faulty ports, cables, and motherboard issues.

Best Ways to Fix Vizio Smart TV No Signal Issue
Here we have listed an effective method to address Vizio Smart TV no signal issue. By reading and applying the outlined solutions, you may easily tackle the error.
The first and foremost thing you have to do is check your input source on your Vizio TV to ensure the input source is set as correct. While, Smart TVs come with multiple input sources, therefore it is necessary to choose the correct input source to get the suitable signal for your streaming device.
However, you can verify that you’re viewing the correct input source by pressing the input button on the Vizio Smart TV remote. When you change the input source to the correct source, you will get the audio and video displayed back on the TV screen.
2. Ensure Cables are Firmly Connected
HDMI cable is important for optimal signal transmission, as it plays a crucial role. The HDMI cable should be plugged properly to the port on your TV. If the connection is not firmly attached, the signal may not transfer which results in “No signal” error on the TV screen. To address this issue, you can start by unplugging the HDMI cables from the power socket and re-plugging it back. Make sure to choose and select the correct HDMI input source.
However, If unplugging and replugging the HDMI cable doesn’t work, it is likely there is an issue with your cable itself. No matter how premium your HDMI cable is, it can’t last forever and here’s the same. If you’ve been using the cable for a long period, it may have been damaged or torn out which results in “No signal” error on the Smart TV. In such a case, you must replace the cable with a compatible one.
There are many HDMI cables available on the market, so choose the cable wisely with high and premium quality. Picking a cheap HDMI cable can result in poor signal quality and it causes other issues. If replacing the cable didn’t work, inspect the HDMI port on your Smart TV carefully. It may be possible that the pins are broken or bent. If so, you can use a different HDMI port.

One of the most effective ways is to restart your Vizio Smart TV. Sometimes, when you switch to a local channel or other streaming devices, the TV might display a “No signal” error. This can be easily fixed by restarting the Smart TV, especially when the error typically appears due to software conflicts.
All you have to do is unplug the cable from the power socket and wait for 20 seconds and so. Then, attach the cable to the power socket and turn on the Smart TV. Once the Smart TV is turned on, then switch to the input source for which your TV channels or streaming devices are connected. Check if the “No signal” error has been fixed now. If the issue persists, follow the next method.
