Power cycle the television. Unplug the power cord from the back of the TV or the wall outlet (whichever is easier to access.) Hold down the power button on the side of the TV for 5 seconds. Reconnect the power cord, and power on the television.

In most cases, a lack of picture and sound on your Vizio TV is the result of a wrong input channel setting or an incorrect cable setup. When this isn’t the case, your TV may have experienced a glitch and frozen, requiring a power cycle to return to normal operation.

Unplug the TV cord from the power socket. Leave it unplugged and while it’s unplugged press and hold the Power button on the TV for 25 seconds. Release the power button and plug the cord back in. Turn ON the TV using the remote control or manually and check if there’s picture on the Screen.

TV screen is black and there’s no sound If the power indicator light is on, there may be an issue with the TV’s software. Unplug the TV from the wall, and, if possible, remove the power cord from the back of the TV to perform a soft reset. Wait 30 seconds, and plug the TV back into a working outlet to test it again.

A Vizio TV screen may go black due to features such as ‘Screen Mute’ or ‘Sleep Timer’. It may also be a result of a loose/faulty connection, power issues, software error/bug or broken hardware. Most issues can be fixed by updating or resetting the TV, securing all cable or changing the TV settings.

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. In that regard, we recommend checking if your HDMI cable is working on another device before you proceed any further.

If your TV is getting its signal from an external source. i.e. a cable box or a DVD player, then the possible reason why it is not displaying a picture is that the cable connecting the TV to the cable box or DVD player is loose or damaged. The cable that is responsible for displaying a picture is the yellow cable.

This would mean that either a CABLE BOX, SAT BOX, COAX CABLE, HDMI CABLE, ETC may not be working properly, something is loose, or needs reset. -Reset ALL components by unplugging them for 5 minutes including the TV. -Be sure all COAX CABLES and HDMI CABLES are tight and properly connected.

>Sometimes, when you’re not getting a picture, it’s because the TV isn’t powering on. To determine if this is a display issue, or a power issue, check the power light on your TV. It will likely be in the center, of left side of your TV. If the light is coming on- so is the TV.

Try accessing the menu or changing the channels or something that would cause some graphics on the screen. If you can see an image then this indicates the back lights are not functioning, probably due to a faulty inverter board. Please let me know your results.

Press and hold the mute button on the VIZIO remote for 3 to 5 seconds. Some VIZIO TV’s have a “Mute Screen” feature that turns the screen off if you are streaming an audio application (Pandora, Spotify, etc) and don’t want the screen on. To activate/deactivate this feature, hold the mute button for 3-5 seconds.
