1. VIZIO TV HDMI PORTS NOT WORKING

If your HDMI port on your Vizio TV has stopped working, there could be a number of reasons for this. The solutions listed below can help you get things back up and running.

RESTART THE TV

The majority of people have discovered that restarting the TV using the procedure outlined below resolves the issue of their Vizio TV not detecting an HDMI input. This is referred to as a hard restart.

1. Turn off your device, followed by your Vizio TV.
2. Disconnect all HDMI cables from the TV.
3. Unplug your television from the wall outlet.
4. For 30 seconds, press and hold the power button on the TV. This is typically found on the back of most Vizio TVs, but it may also be found on the side of the TV.
5. Reconnect your HDMI cables to the TV.
6. Reconnect the TV to the wall outlet and turn it on.

If the above does not work, you may need to try each of the troubleshooting methods listed below.

CHECK HDMI CABLE

The first thing to look for is a faulty HDMI cable. These cables can become loose or damaged over time. Unfortunately, some cables can be defective from the start.

Unplug both ends of the cable and plug them back into the TV and device. You could even experiment with swapping the ends to see if one end fits better in your TV or device.

Check that you’ve pushed the cable all the way in. If this doesn’t work, try the same cable in another TV or a different HDMI cable in your Vizio TV to see if it’s a faulty or broken cable. Take note of which HDMI port you’re using.

CHECK INPUT SOURCE

The next thing to check is the input source on your television. This may appear to be a simple solution, but it has worked for some people.

When you inserted the HDMI cable, you probably noticed that the port was labeled ‘1’ or ‘2’. Check that you have selected the correct input source by pressing the ‘Input’ button on your remote.

You can cycle through each one to double-check if you’re unsure or if they’ve been labeled differently.

BROKEN HDMI PORTS

You could also try a different HDMI port. Individual ports can sometimes fail due to overuse. Just make sure to change the source of the input as well.

If none of the HDMI ports appear to be working, the problem could be with the TV’s computer chip, also known as the MotherBoard. If all of the ports are broken, this will need to be replaced.

Because this can be costly, try some of the other troubleshooting methods listed below or contact Vizio support to see if they agree.

They may even offer to replace the television as part of the warranty. In the meantime, if you need to use your device, you could always find an HDMI to AV converter.

This allows you to connect a newer device to the old TV input. Keep in mind that your picture quality will suffer as a result, so this is only a temporary fix.

DEVICE DISPLAY SETTINGS (LAPTOPS)

You should also check your device’s display settings. This mostly applies to laptops because you can plug in a laptop and not see anything on the second screen.

The following methods will allow you to access your display settings on a Windows or Apple computer.

• Start > Settings > System > Display in Windows 10
• In older versions of Windows, go to Start > Control Panel > Display.
• Apple Menu > System Preferences > Displays > Displays > Displays

You may need to fiddle with the settings here, but the most common problem is that the display is set to only the laptop.

For the audio/visual input to work, make sure you have chosen to mirror or extend your display onto the TV. You may also need to double-check the resolution, but I’ll explain why later.

UPDATE YOUR FIRMWARE

If there is a bug in the firmware that is preventing your HDMI ports from working, a new update with the bug fix may be available. If your TV’s firmware is out of date, use the steps below to update it.

1. On your remote, press the ‘Menu’ button.
2. Select System > Check for Updates.
3. If an update is available, click ‘Confirm’ to begin the installation.
4. Wait for the update to finish.

RESET THE TV TO FACTORY SETTINGS

If any settings have been changed that have caused your HDMI ports to stop responding, resetting the TV to its factory settings will help. It will also help if your TV’s latest firmware contains any firmware bugs.

Resetting the TV to factory settings returns it to its original firmware. It will also delete all of your saved preferences and downloaded apps, so only do this if you are willing to start from scratch with your TV.

1. On the remote, press the ‘Menu’ button.
2. Go to System > Reset & Admin.
3. Enter your passcode or ‘0000’ as the default code.
4. Select ‘Reset’ and then press the ‘Ok’ button on the remote.
5. Wait for the TV to turn off and then back on.
6. Go through the TV setup procedure.

Before attempting to update your TV again, ensure that the HDMI ports are operational.

2. VIZIO TV HDMI NOT SUPPORTED / COMPATIBLE

If your Vizio TV says HDMI is ‘Not Supported’ or ‘Not Compatible,’ this is most likely due to your device’s resolution. The user manual for your Vizio TV will tell you which resolutions are supported.

Once you’ve determined which resolution the TV will accept, go to the display settings on your device, whether it’s a DVD player, laptop, gaming console, or other streaming device.

The most common resolutions to experiment with are 19201080 (‘1080p’) or 1280720 (‘720p’). If this does not resolve the problem, try the troubleshooting methods listed above.

3. VIZIO TV NOT CONNECTING TO HDMI

There is a reason why your Vizio TV is not reading, picking up, recognizing, or detecting the HDMI signal. These could be any of the issues listed below.

• The HDMI cable is faulty/loose, or the HDMI port is faulty.
• On the television, the incorrect input source is selected.
• The display settings are either preventing or incompatible with the signal.
• The firmware on the television is out of date.
• The TV’s settings have been changed, or there is a bug in the most recent firmware.

You can find solutions to these problems in the sections above.

4. VIZIO TV SAYS NO SIGNAL WHEN HDMI IS PLUGGED IN

The ‘No Signal’ message on your Vizio TV indicates that the HDMI is not being recognized. The troubleshooting steps outlined in this article should resolve the issue.

If none of these solutions work, you may need to contact Vizio support in your area.
