Methods to fix Vizio TV Black Screen With Sound

1. Restart your TV

The first thing you should do if your Vizio TV has a black screen with sound is to restart the TV. Many users have reported that this simple fix works for them.

To restart your TV, simply unplug it from the power outlet and then plug it back in. Wait for the TV to turn on again and see if the issue is resolved.

If restarting your TV doesn’t work, you may need to try some other methods to fix the problem. Some of these include checking your cables, updating the software on your TV, and resetting your TV’s settings.

2. Check all of your connections

Another possible reason for your Vizio TV to display a blank screen with sound is that one of your connections may be faulty or loose.

To check all of your connections, start by making sure that all of your cables are plugged in properly. You should also make sure that the cables are free from any signs of damage or wear and tear.

3. Try a different input

If you’re still getting a black screen with sound, the issue may be with the input you’re using.

To check if this is the case, try switching to a different input. For example, if you’re using HDMI 1, try switching to HDMI 2.

If you’re able to get a picture and sound on the other input, then you know that the issue is with the first input.

4. Wrong input channel

If you’re trying to watch a specific channel and you’re getting a black screen with sound, you may be on the wrong input channel.

To fix this, simply press the input button on your TV remote until you find the correct channel. Then try watching your desired channel again.

5. Perform a soft reset

If you’ve tried all of the above methods and you’re still getting a black screen with sound, you may need to perform a soft reset.

To do this, simply:

1. Press and hold the power button on your Vizio TV for a few seconds until the screen goes blank.

2. Wait for at least 30 seconds, then press the power button again to turn the TV back on.

3. Check to see if your TV is working properly now. If not, you may need to contact Vizio support for further assistance.

6. Perform a factory reset

If a soft reset doesn’t work, you may need to try a factory reset. This will erase all of your TV’s settings and revert it to its default state.

Before you proceed, make sure that you have a backup of your TV’s settings. This way, you can restore them after the reset is complete.

To perform a factory reset, simply follow these steps:

1. Press and hold the power button on your Vizio TV for a few seconds until the screen goes blank.

2. While the TV is off press and hold the menu button on your remote for at least 5 seconds.

3. The TV will turn on again and a new menu will appear. From there, navigate to Settings > Reset and Admin> Factory Reset.

4. Select “Factory Reset” again, then wait for the reset process to complete.

5. After your TV has been reset, restore your settings from the backup you made earlier.

But a factory reset will delete all the data from your TV. So, you should try this method as a last resort.

7. Update firmware

In some cases, a black screen with sound may be caused by problems with your TV’s firmware. If this is the case, you may need to update your firmware to fix the issue.

To check if there’s an update available for your TV and learn how to install it, head over to Vizio’s website and search for your specific model of TV. Once you’ve found the appropriate update for your TV, follow the instructions on how to install it and check to see if your issue has been resolved.

8. Replace your TV’s power supply or mainboard

If you’ve tried all of the above methods and you’re still getting a black screen with sound, there may be an issue with your TV’s power supply or mainboard.

So, you’ll need to replace one or both of these components to fix the problem.

9. Software tests

To check whether there is a software issue, please follow these steps:

1. Go to Settings and navigate to System > Advanced system settings.

2. Select “Restore Default Settings”.

3. Click “OK” to confirm.

4. After the reset is complete, try using your TV again and check to see if the issue has been resolved.

There is another test known as the flashlight test. This test is helpful in most cases. Just follow these simple steps:

1. Turn off your TV.

2. Unplug the power cord from the outlet or TV. You can either directly unplug it or use the power button on the TV to turn it off.

3. Press and hold the power button on your TV for 30 seconds.

4. While still holding the power button, plug the power cord back into the outlet or TV.

5. Continue holding the power button for an additional 60 seconds after the cord has been plugged in.

6. After 60 seconds have passed, release the power button and turn on your TV. Check to see if the problem has been resolved.

10. Change display settings

If you’re still getting a black screen with sound after trying all of the above methods, it’s possible that your TV’s display settings are to blame. To fix this, you may need to adjust your display settings or change the input source for your TV.

To try adjusting your display settings, go to Settings and navigate to System > Display > Adjustments. From there, you can tweak various display settings such as brightness, contrast, and color levels to fix the issue.

If this doesn’t work, you may need to try changing the input source for your TV. This can be done by going to Settings > Inputs and choosing a different input mode such as HDMI or AV. Once you’ve selected a new input mode, try using your TV again and check to see if the issue has been resolved.

11. Hardware tests

There are a few hardware tests that you can perform to check whether there is an issue with your TV’s power supply or mainboard.

First, you’ll need to unplug your TV from the power outlet and remove the back panel. Once you’ve done that, you can begin the following hardware tests:

1. Check your TV’s power supply for signs of damage or malfunction. Look for burn marks, bulging capacitors, loose wires, or any other issues that may be causing problems with your TV’s power supply.

2. Examine your mainboard to see if there are any damaged or disconnected components. You can test for damage by checking for burn marks, bulging capacitors, or other signs of overheating.

3. Test your TV’s power cord and ensure that it is not loose or damaged in any way. If you’ve confirmed that the power cord is working properly, try using a different outlet to see if this fixes the issue.

12. Hardware fix

If all software tips have not helped then most likely there is a hardware issue with your TV that requires replacing either the power supply or mainboard.

To replace these components, you will need to follow a step-by-step guide
