VIZIO TV REGULARLY TURNS OFF/SHUTS DOWN

If your Vizio TV keeps turning off at random, try the general troubleshooting methods listed below. These are common in most electronic devices and are very effective in dealing with most problems.

1. Hard Reset The TV

A hard reset will remember all of your personal preferences, but it will also frequently resolve unknown issues with your television. Because it is simple and effective, this is something worth trying every time you have a problem.

  1. Turn off the TV (if possible) and all other devices.
  2. Unplug the television from the power outlet.
  3. For 30 seconds, press and hold the power button on the back of the TV.
  4. Allow the TV to be unplugged for another 10 minutes.
  5. Reconnect the TV and turn it on.

2. Reset to Factory Settings

A TV that has been reset to factory settings will revert to its original state, just as it was when you first bought it. This will delete any saved preferences and downloaded content, so only do this if you are at a loss for alternatives.

  1. On the remote, press the ‘Menu’ button.
  2. Select System > Reset & Admin.
  3. Choose ‘Reset TV to Factory Defaults.’
  4. Enter your passcode or the ‘0000’ default passcode.
  5. Choose ‘Reset’ and confirm.
  6. Wait for the television to turn off and then back on.

3. Update the Firmware

It is not uncommon for TVs to develop firmware bugs as a result of software updates. Vizio will then issue a new update to address the previous bug.

If this is the case, ensure that your firmware is current. The TV should update automatically, but you can update it manually by following the steps below.

  • On the remote, press the ‘Menu’ button.
  • Select System > Check for Updates.
  • If an update is available, confirm that you want to run it.

4. Disable ‘Auto Power Off’ Feature

Vizio TVs have a ‘Auto-Off’ feature that turns the television off after a predetermined amount of time. This should only happen when the TV is turned off, but it could explain why your TV shuts down unexpectedly. You can turn off this feature by following the steps below.

  • Timers > Auto Power Off > Off > Menu

5. Connect to the wall directly

There could also be a power outage. This happens when there are too many devices connected to the same power source via a power board/strip. If this is the case, plugging the TV directly into a wall outlet should solve the problem.

6. Prevent Overheating

If the TV detects overheating, it will turn off. If this is not the case, it is possible that the sensors are broken and must be replaced. This entails replacing the TV’s mother board or arranging for a technician to inspect the TV.

If the problem is overheating, you should find that lowering the processing power and cooling the TV will help. Begin by directing a fan at the back of your television (the hottest part). Reduce the processing power, and thus the amount of heat generated, by lowering the TV’s brightness, sharpness, contrast, and color.

VIZIO TV KEEPS TURNING ON AND OFF

If your Vizio TV keeps turning off and on, it could be a different issue. The most straightforward explanation is a loose power cord, which should be fixed by inserting it all the way

This issue would cause the power source to be connected and disconnected from the TV on a regular basis. Other options are listed below, but if they do not work, you should try some of the general troubleshooting methods listed above.

1. Be Mindful of Other Remote Controls

It is possible that another remote control is interfering with your infrared sensor. This mostly happens with other Vizio remotes that have similar programming. If this is the case, you can try using the SmartCast phone app to control the TV from your phone.

2. Turn off the CEC function.

The CEC function allows you to control the volume and power of your TV from another device’s remote. This can occasionally fail, causing your device to send ‘Power On’ or ‘Power Off’ messages to your TV. You can stop this communication by disabling the CEC feature as described below.

  • Menu > System > CEC > Off

3. Turn Eco Mode On

To save power, Eco Mode will automatically disable unnecessary communication with other devices. This includes a third party’s SmartCast app sending mixed messages to your TV. You can enable Eco Mode by following the steps below.

  • System > Power Mode > Eco Mode (Menu)

4. Turn on QuickStart Mode

If Eco Mode does not work, some users have discovered that enabling QuickStart Mode solves the problem. This can be enabled by following the steps outlined below. QuickStart Mode can be accessed via the menu System > Power Mode > QuickStart Mode.

VIZIO TV JUST SHUT OFF AND WON’T COME BACK ON

Other than a hard reset, there isn’t much else you can do for a TV that won’t turn on. The steps for this can be found at the beginning of this article.

If this does not work, the mother board has most likely been damaged or has reached the end of its useful life. If this is the case, you can either try to replace the mother board or replace the television.

VIZIO TV WON’T TURN OFF

Some people have experienced the opposite problem, in which their Vizio TV will not turn off. This is frequently described as the screen going dark while the backlight remains on. The solutions listed below have proven to be effective in dealing with this particular problem.

1. Alter the TV Input

When the TV is set to a specific input, it will occasionally refuse to turn off. If you change the input or return to the TV’s main menu, you may be able to turn the TV off.

As previously stated, this could be a problem with the CEC features. If this is the case, you might want to disable this feature. The input device is most likely sending mixed signals to the TV and interfering with the user’s commands to turn off the TV.

2. Discharge The Internal Memory Of The Television.

A hard reset is another option. When the internal memory becomes overloaded, it must be discharged. Holding the power button for 30 seconds while leaving the TV unplugged allows the memory to be discharged.

VIZIO TV WON’T TURN OFF WITH REMOTE

If it’s only the remote that’s not turning off your TV, there could be a problem with the remote itself. To begin, replace the batteries in the remote to see if that is the source of the problem. However, this would cause all of the remote’s buttons to fail.

Make sure nothing is in the way of the infrared signal between the remote and the TV. If the path is clear and you have new batteries in your remote, try resetting it.

1. Reset the Remote

Remove the batteries from your Vizio remote and press each button several times to reset it. This will drain the remote’s residual charge, clearing any malfunctioning components. It will also aid in the removal of any debris that may have become lodged beneath the power button.

If none of these methods work, try some of the general troubleshooting methods mentioned earlier in this article.

In the TV settings, you can check the time limit, disable the timer, or completely disable it. A faulty power plug, power strip, or surge protector could be causing power problems.

What causes Vizio TV to freeze?
