Vizio TVs are affordable and high-quality, but it doesn’t mean that they will go for years without developing some issues, no matter how minor they are. While watching TV, you may notice that it frequently turns off after some time. This can be frustrating, especially if you don’t know the underlying cause. Our experts will share some surefire ways to fix the issue without repairs. 

Troubleshooting Different Vizio TV Issues

Your Vizio TV might be turning off frequently for some reason. It is pretty normal and nothing to panic about, at least until you have tried out all the solutions here. You might have enabled things that could trigger the issue, such as enabling CEC and Auto-Off function. 

It could also be the power surge, sages remote, or loose tv cable. It’s also possible that another device is interfering with the circuitry or the input device’s internal memory is overloaded. While you wonder what the cause could be, our engineers will explain how to troubleshoot the different Vizio TV issues. 

What to Do If Vizio TV Abruptly Shuts Down

Fix #2: Hard Reset

Unlike a factory reset, your personal preferences are kept with a hard reset. To do this, turn off the TV and all the connected devices, unplug it from the wall outlet, and hold the power button on the TV’s back for thirty seconds. 


Let the TV remain unplugged for an additional ten minutes before plugging it back on.

Fix #3: Check for Firmware Updates

An old firmware version can cause your TV to misbehave. So, it’s crucial that the firmware is updated unless there’s a bug. If the TV isn’t updated automatically, do the following:

Select ‘Menu’ on the remote, scroll to System, and select. Tap on Check for Updates and confirm you want to update your device. 

Fix #4: Plug Directly into the Wall Outlet

When several devices are connected simultaneously, your TV can turn off. Therefore, you should plug the TV into a different outlet. 

Fix #5: Let it Cool Down in Case of Overheating

You can cool the TV down by installing a fan at the back of the TV or by letting it rest for a couple of hours.

Fix #6: Ensure Auto-Off Settings is Deactivated

The Auto-Off function turns off the TV after a specified time. To disable this feature, go to Menu and select Timers. Navigate to Auto Power Off and toggle it off. 

Fix #7: Factory Reset

A factory reset reverts the TV to its default state. This will erase all your saved preferences. Our engineers recommend that you do this when you are out of options. 

To factory reset; Select “Menu” on the remote, scroll to System, and click. 

Select Reset & Admin > Reset stab to Factory Defaults. Input your passcode or the default one, which is 0000.

Tap on Reset and confirm. Your TV will reboot after doing that.
