Common Causes of Sound But No Picture
If you have gone through the basic troubleshooting steps and are still experiencing sound but no picture on your Vizio TV, there may be other underlying issues that need to be addressed.
Here are some of the most common causes of this problem and what you can do to fix them.
Broken Screen
If your Vizio TV is displaying sound but no picture, it may be due to a broken screen.
This can happen if the TV is dropped or hit by an object. Unfortunately, if this is the case, the only solution is to replace the screen, which can be a costly repair.

Faulty Backlight
If the backlight on your Vizio TV is not working properly, it can cause the screen to display a black or gray image with sound.
This is often caused by a faulty LED strip or power supply board. You can usually tell if the backlight is the issue by shining a flashlight on the screen and looking for any faint images.
If you see images, then the backlight is likely the problem. To fix this issue, you may need to replace the LED strip or power supply board.
Bad Power Supply
If the power supply on your Vizio TV is not functioning properly, it can cause the TV to display sound but no picture.
This is often due to a faulty capacitor or other components on the power supply board. To fix this issue, you may need to replace the power supply board.
Loose or Damaged Ribbon Cable
The ribbon cable is a flat cable that connects the TV’s mainboard to the screen.
If this cable is loose or damaged, it can cause the TV to display sound but no picture. To fix this issue, you may need to open the TV and check the cable for damage or looseness. You might need to replace it if it is damaged.
Faulty Mainboard
If the mainboard on your Vizio TV is not working properly, it can cause the TV to display sound but no picture.
This can happen due to a faulty board component or other issues such as firmware corruption. To fix this issue, you may need to replace the mainboard.
Incompatible HDMI Cables
If you are using HDMI cables to connect external devices to your Vizio TV, it is important to use compatible cables.
Incompatible HDMI cables can cause issues with the TV’s display and result in sound but no picture. Make sure that you are using HDMI cables that are compatible with your TV and external devices.
