Possible Reasons Why Your Vizio TV has Sound but No Picture.
Failed Old boards- a TV isn’t just the screen you see from the outside. It has circuit boards that enable it to function properly. If these cables fail to work properly, your Vizio TV will automatically experience the problem of having sound with no pictures.
Inadequate Power Supply- when your power supply keeps going on and off, your Vizio TV might be affected. You might be hearing the sound, but the pictures may fail to show.
With the above reason of a Vizio TV having sound but showing no pictures, you might be forced to try the following steps.
Try Flashlight Tests
The black light is usually the main part of any non-OLED TV. These particular arrays of LEDs light up the screen reflecting it into the image you want to see. If this black light stops working, you will fail to see the images.
The flashlight test enhances stimulation at the backlight of your TV. The following are steps followed when doing a flashlight test.
Get a very powerful flashlight. Turn on your Vizio television. Make sure that your lights are turned off. Turn your flashlight on and hold it an inch away from your TV. Keenly look at the screen and see if you have an image. Move the flashlight closely around the screen. If you can see anything, your backlight is faulty and requires urgent replacement. If you don’t see anything, your matrix display might be an issue.
If you finish diagnosing your Vizio TV and get to know that your backlight has an issue, you can, at this point, call the Vizio customer care team so that they can offer the kind of support needed.
Check Your Cables
It is always advisable to check on your cables regularly. It is usually good to do this practice once in a while and replace all the faulty cables. You can also try to reconnect the TV directly into the socket if you have tried using a power strip before.
You can also turn your TV off, especially while experiencing thunderstorms, or plug the TV in a surge protector to save the Vizio TV from power fluctuations.
Purpose to Change Input Channels
The TV might secede to go into audio-only mode by itself. The reason as to why this happens largely depends on the type of TV you have. Here is a universal way to fix it.
Take your remote and the input from the current one to a particular one you want to watch. This process will particularly fix the issue of no pictures if there was particularly an issue. Try changing the inputs once again.
