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
If your TV abruptly shuts down, try the following troubleshooting tips.
Fix #1: Power Cycling
To power cycle your TV, you must first turn it off, then unplug the power cord on its back.
Next, hold the power button for five seconds. Afterward, put the power cord back to the plug.
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 commence factory resetting, find and press the “Menu” on the remote. Click on it then, scroll to System, and click.
Find and select the Reset & Admin option. Next, press Reset to Factory Defaults. You will be required to enter your passcode. If you don’t have it, enter the default one, which is 0000.
Tap on Reset and confirm. Your TV will reboot after doing that.
What to Do If Your Vizio TV Turns On and Off Randomly
If your Vizio TV keeps turning off and on randomly, our technical support team suggests the following solutions.

Fix #3: Deactivate CEC Settings
CEC enables you to control the TV using another device’s remote. You can disable this feature by going to Menu > System > Power Mode and clicking on Eco Mode.
Fix #4: Enable Eco Mode or QuickStart Mode
Eco Mode saves power by disabling certain features. Select Menu > System > Power Mode, and click on Eco Mode/QuickStart Mode to enable it.
Fix #5: Tweak Video Settings
If you have the Advanced Video Settings activated, it can cause visuals to flicker. Go to Settings > Display > Advanced Video, and toggle it off.
Fix #6: Check if Sleep Timer is Active
If this is active, you should deactivate it because it can cause the TV to blackout occasionally. Go to Menu, scroll to Timers > Sleep Timer. Then turn it off.
Fix #7: Inspect HDMI Port for Damage
Damaged ports can cause poor video signal transmission. You can’t do much here, so contact a professional to fix it.
