My Vizio TV has sound but no picture is a frequently asked question among the Vizio community for quite some time now.
Here we have gathered the most useful information and troubleshooting techniques that will most likely resolve your issue in no time.
Sound but no picture could be caused by several factors. It could be the result of a wrong input, incorrect channel settings, or faulty cable setup.
There could be other possibilities such as bad power flow throughout your Vizio TV, or an OS issue for which we will discuss later in this post.
Before we jump right into the solutions, we shall introduce more firmly the origin of this malfunction which will significantly ease up the troubleshooting process.
Why Vizio TV Has Sound But No Picture
The number one reason for issues where sound is there but the screen is black is a faulty cable.
All these issues could be caused by a faulty HDMI cable that does not deliver a proper picture signal.
In that regard, we recommend checking if your HDMI cable is working on another device before you proceed any further.
Another possible cause would be due to a faulty or insufficient power supply.
Power malfunctions could be internal and external and further in the post, we are going to get into details about each category to help you with the process.
Keep in mind that TVs periodically may freeze, showing that it is still working but not displaying any information.
This could be a simple glitch that is fixed with a restart or a hardware problem that will require a technical check.
One of the more rare occasions is an AV connection problem which could interfere with your video allowing only sound to pass through.
When your Vizio TV is turned on, there could be disruption in the physical connection between your TV and the transmitting device.
To check and potentially fix those issues, follow the guidelines we have prepared for you down below.
How To Fix Vizio TV No Picture but Has Sound?
Now when you know what the possible causes for this issue are, it would be appropriate, to start with proven to work methods gathered from people that solved the same issue as yours.
It is important to follow our methods in numerical order because they are designed to discover and solve any issues if followed precisely.
Method #1 Restart Vizio TV
Many similar issues could be caused by temporal glitches that can be resolved by simply rebooting your TV.
Users periodically report similar malfunctions, so before trying to apply more drastic troubleshooting measures, our suggestion is to perform a restart on your Vizio TV.
If there is a more severe issue, a restart might not help, but if there is a temporal glitch preventing the video from playing out, it might be helpful.
Method #2 Power Cycle Vizio
If your Vizio smart TV has sound but no picture even after restarting the TV, there is a better way of disengaging your device from the power entirely.
Sometimes, black screens and issues similar to yours could be caused by inappropriate power flowing throughout your device.
In that regard, we suggest performing a Power Cycle on your Vizio TV.
This method is well-known to deal with temporal power issues and takes place as one of the easiest to apply approaches.
Here is how to do it correctly:
- Turn off your Vizio TV using the remote or the device’s button.
- Unplug the power cable from the power supply.
- Wait for at least 3-5 minutes.
- Plug the power cable back to the power supply.
- See if the issue still persists.
By performing these simple steps, you will easily perform a power cycle on your Vizio TV and hopefully, get your picture back on the screen.
If you are using a power divider or strip on your Vizio TV, we suggest plugging the power cable directly into the wall outlet.
By doing so, you will hopefully evade malicious consequences related to malfunctions of the power device.
Method #3 Verify Cable Connections
Another common cause for black screens is inappropriate cable connections.
When purchasing your Vizio TV, the unused slot for HDMI and USB cables are still not worn out.
In other words, it will require a greater force to plug a cable all the way in.
This is when the problems are starting to occur.
Some Vizio users do not want to force their cable into the TV and frequently leave the cable not plugged all the way in.
As you already figured out, this could be the origin of plenty of issues and not only black screens.
Other than that, you could be having a faulty cable or faulty port.
Let’s take a look at both scenarios and figure out which one applies to your case.
Plug your source cable all the way in (HDMI or AVIN) and check if it is working.
If you are having concerns that the cable might be faulty, feel free to test it on another device to confirm this theory.
After verifying the condition of your cable and the issue still persists, you might have to check the ports of your Vizio TV.
If you are confident that your cable is fully functional, make sure to try each and every available slot on your Vizio TV.
Don’t forget to select the corresponding source input from the TV settings.
Method #4 Switch Channel
As unbelievable as it may sound, the channel you are currently watching through your Vizio TV might be experiencing video issues.
Such events commonly occur within the channel’s host service and might require a while for the issue to be resolved.
However, to identify if this is the reason for the issue, simply browse through other channels to see if you would still have no video but sound.
Try accessing online media platforms to find out if the issue is related to the TV channels or TV screen.
