There are many reasons why the Vizio Smart TV might be turning itself off. Let’s take a look at them one by one and see how to fix these issues.

Sleep Timer

Now, with a lot of electronic devices, they have a special mode called eco-mode or power mode. Your Vizio Smart TV also has a special power-saving mode. This power-saving mode kick in when the TV is not being used for a certain time. In this case, the TV puts itself into sleep mode or just gradually shuts down. Here is how you can change this power mode.

Step 1: From the home screen, select the Settings option.

Step 2: With the Settings page open, scroll and select the System option.

Step 3: With the System menu open, select the Power Mode settings.

Step 4: Select it and see if the selected mode is set to Eco. If it is, you need to change it to Quick-Start.

Step 5: Your Vizio TV should now stop suddenly turning itself off for no reason.

For some models, you need to navigate to Settings > System > Timers > Sleep Timer and turn it off.

Adjust Power Scheduling

If you have enabled a timer for your Vizio Smart TV to power up or power off, this can be a reason that at a certain particular time, the TV simply decides to power itself off. Here is how you can disable the auto-power-off feature.

Step 1: Press the Menu button on the remote control and navigate to Settings.

Step 2: Now, scroll and select the Timers option.

Step 3: Select the Auto Power option and see if it has been set to On.

Step 4: If the option is set to On, select it and choose the Off option.

Your Vizio Smart TV will now no longer power itself off at a particular time.

Power Cycle the Smart TV

In such cases, when the TV is simply switching itself off, you might need to simply perform a power cycle if you suspect it has nothing to do with the above two settings. For this, simply power the TV off, disconnect it from the power source, leave it like that for a few minutes, and then plug it back into the power source. The TV should now be functioning perfectly after performing this soft reset.

Check for Damaged Cables

If the Vizio Smart TV that you are using has some damaged power cables, then it could be a sign that the TV isn’t receiving its power properly, and it is time to either get the wire replaced or get yourself a new TV altogether. Apart from that, you need to check the TV’s plug to see if there are burn marks or any kind of black spots. If there is, it’s probably time to get some repairs done.

Let the TV Cool Down

There might be chances that your TV will turn off itself because of safety measures against overheating. To confirm it, just touch the back of the Vizio TV to see if it’s overheating or not. If it’s, power off the TV and let it rest for a few minutes or until it cools down. Once it cools down, turn on your Vizio TV, and it should not turn off.
