The average lifespan of Vizio TVs is about 7 years, but this depends on how often you use them, and their constant high-setting configuration.

If you've only recently bought a Vizio TV and you're already experiencing technical problems, you will be glad to know that some of them can be fixed in a jiffy. If your Vizio TV won't turn on or can't install apps, we're here to solve common Vizio TV issues that will make your setup more convenient and hassle-free.

5 Common Vizio TV Problems Solved

Issue #1: My Vizio TV Shows Pictures But There's No Sound

The first thing you need to check is to make sure there are batteries in your Vizio remote control and your built-in speaker volume is not set to zero or muted.

But take an extra step and check the Audio Settings and turn the TV Speaker setting ON. If the issue is not resolved, you may need to replace the built-in speaker or try connecting to an external device, like Vizio sound bars.

Issue #2: Vizio TV Black Screen and LED Indicator Light On

You may have experienced the Vizio TV black screen of death before, but it is a common issue that's not hard to fix.

First things first, turn the unit off by pressing the power button on the remote control and unplug the power cord from the TV.This is where the "Flashlight Test" comes into play. All you need to do is find a bright flashlight, position yourself two inches away and shine the light directly on the TV screen.

If you see an image but your Vizio TV still has a blank screen, then it's safe to say it may have problems with the backlight on the display, the inverter board, or there may be other parts of the TV that are malfunctioning and needs to be looked into.

Issue #3: My Vizio TV Won't Connect to the Wi-Fi

It's uncommon in today's modern world if your TV wasn't connected to the Wi-Fi network. But it's also common for your Vizio Smart TV to disconnect from the Wi-Fi network.

Here are some troubleshooting tips to solve this Vizio TV problem:

First, try troubleshooting your Wi-Fi connection by making sure you have a stable internet connection that can handle multiple devices.
Check if the power cord is plugged in tightly or unplug it from the wall outlet and plug it back in again, just to make sure the power source is working.

Next, turn the Dynamic Host Configuration Protocol (DHCP) [1] setting ON. By turning this setting on, it will be easier for your Vizio unit and a different device to connect to the same Wi-Fi network and router without any problems.

Here's how to turn on the DHCP:

Press the Menu button.
Go to Network.
Under Manual Setup select DHCP.
Make sure the DHCP is ON.
Now, turn off the TV and unplug the power cable of your TV and Wi-Fi router from the power outlet.
Hold the power buttons of your TV and Wi-Fi router and release it after 10 seconds.
Turn both of those devices on and connect your Vizio TV to the internet.

Another option is to connect your device through a wired Ethernet connection. A wired internet connection is more stable than connecting wirelessly.

Issue #4: Why Is My TV Menu Not Working?

If your Vizio TV menu is not working, this issue is possibly caused by your Vizio TV remote.

Issue #5: What's Happening to My Flickering Vizio TV Screen?

The black screen isn't the only common Vizio TV problem. You may also encounter a flickering or blinking screen on Vizio TVs. Even high-end smart TV brands deal with this issue too.

Before you do anything else, unplug all of your cables and external devices from the power supply and restart your television.

If the issue isn't resolved by then, check the Advanced Video Settings . There may be some effects that are active, causing the TV to flicker. Smart and OLED TVs can give you dazzling image quality with vibrant colors, however, they can be very sensitive and prone to unstable behavior.

If the flickering hasn't stopped, conduct a power cycle or a factory reset.
