How To Fix Vizio TV Keeps Turning Off (2026)

If your Vizio TV keeps turning off on its own, the cause is usually power, a timer, or a signal telling it to shut down.

It is rarely a dead TV, and most fixes take under 15 minutes.

Work through the steps below in order, starting with the free and fast ones.

Why does my Vizio TV keep turning off?

What order should you try the fixes in?

Start with the cheapest checks, because they solve most cases.

Step 1: check the power cord and outlet

A loose cable is the simplest reason a TV loses power.

• Push the cord firmly into the back of the TV.
• Test the outlet with a device you know works, such as a phone charger.
• Try plugging the TV straight into the wall if it uses a power strip or surge protector.

Also check the cord for fraying, and replace it if it looks damaged.

Step 2: power cycle the TV

A power cycle clears a temporary software glitch.

1. Turn the TV off.
2. Unplug it from the wall.
3. Wait at least 30 seconds.
4. Plug it back in.
5. Turn it on with the power button on the TV, not the remote.

Step 3: rule out the remote

A stuck power button can send false signals to the TV.

1. Take the batteries out of the remote.
2. Use the TV for a while with the remote unused.
3. If the shutoffs stop, clean the buttons and replace the batteries.

Low batteries can also cause random signals.

Step 4: turn off the sleep timer and auto power off

These timers shut the TV down on purpose, so check them even if you never set them.

On many Vizio models with a Timers menu, the steps look like this.

1. Press Menu on the remote.
2. Open Timers.
3. Set Sleep Timer to Off.
4. Set Auto Power Off to Off. The default is 10 minutes.
5. Press Exit.

Menu names vary by model and software version, so use the menu search or your manual if you do not see Timers.

Step 5: turn off CEC

CEC lets HDMI devices control each other, so a cable box, console or soundbar can send the TV a power-off command.

1. Press Menu on the remote.
2. Open System.
3. Select CEC.
4. Set CEC to Disable.

Turning CEC off means your TV remote will no longer control those connected devices.

Step 6: check the power mode

If the TV wakes and sleeps on its own, switch between the two modes and test for a day.

Step 7: check for overheating

Many TVs have a built-in safety feature that turns the set off when it gets too hot.

• Leave space between the TV and the wall.
• Clean dust from the vents and clear anything blocking them.
• Move cable boxes and players away from the back of the TV.

If the TV shuts off from heat, let it cool for at least an hour before turning it back on.

Step 8: protect against power surges

A power surge can damage the TV’s power supply and make the TV shut down.

Plug the TV into a surge protector, and check for outages in your area if the problem started suddenly.

Step 9: update the software

Software updates can fix bugs that cause random shutdowns.

1. Connect the TV to your Wi-Fi network.
2. Press Menu and open System.
3. Select Check for Updates.
4. Install any update that appears.

If the TV will not stay on long enough to update, see our guide to a Vizio TV that keeps restarting.

Step 10: factory reset the TV

Use a factory reset as a last resort, because it erases your settings, logins and installed apps.

1. Press Menu and open Settings.
2. Go to Admin & Privacy and choose the reset option. The path varies by model.
3. Enter your PIN, which is 0000 if you never set one.
4. Select Reset and confirm.

When should you contact Vizio or a repair shop?

If the TV powers on with no picture, follow our guide to a Vizio TV that turns on but shows no picture.

The power supply and logic board are the likeliest failed parts on an older set, so a repair quote is worth getting before you replace the TV.
