Vizio TV Won’t Turn On—What to Do?

If your Vizio TV suddenly doesn’t turn on, it can be very frustrating. Buying a new TV can be expensive, and getting it repaired can be costly and time-consuming.

Vizio TV Won’t Turn On—What to Do?

Don’t worry, though. If your Vizio fails to power on, there’s no reason to panic. There are a couple of possible reasons why the scenario occurs, and in most cases, it’s not due to a broken TV. Usually, it just takes a few minutes and some troubleshooting to get your TV back up and running.

What to Do if Your Vizio TV Won’t Turn On

Checking on a couple of things often helps resolve this issue in a matter of minutes. With some quick troubleshooting, you’ll be back to watching your favorite shows in no time.


Here are some potential reasons why your Vizio TV won’t turn on and how to resolve them.

Step 1: Check the Remote

If you can’t turn on your Vizio TV using a remote, there might not be anything wrong with the TV at all. Instead, the issue might be with the remote. One of the most common issues is that the batteries are dying or they’re already dead.

To see if this is the case, try replacing the batteries and turning the TV on again. If there’s still nothing happening, there is one more potential remote issue to check.

Step 2: Check the Vizio TV’s Power Source

If you’ve made sure that the remote is working correctly, but the TV still won’t turn on, checking the power is the next logical step.

The first thing you’ll want to do is see if pressing the Menu button yields any results. Sometimes, the TV is on but displays a blank screen. Both the remote and the TV include a Menu button. Try pressing both buttons (not simultaneously) to see if the menu pops up.

If the menu test fails, the TV may indeed be off, and the power source might be an issue. Ensure that your TV is fully plugged into a power outlet before trying to turn it on again.

Step 3: Check the Condition of the Power Cord

The thing that can often prevent your TV from turning on is a loose or damaged cord.

A loose power cord sometimes causes problems for even the most technically savvy among us.

To ensure that the cord fits well, check its connection to both the power outlet and the TV, making sure both connections are plugged in. Even a slightly loose power cord connection can interrupt the flow of electricity to your TV, and it’s not always apparent that your TV is unplugged from its power source.

See if the cord is correctly plugged into the outlet. A good idea would be to unplug it and then plug it back in to ensure it is secure. Another thing you can try is to plug the cord into another outlet.

After you’ve checked the power outlet in the wall, ensure the cord securely connects to the back of the TV. A loose power wire connection happens more often than you might think, especially if you have children or pets that run around the TV or you have a long run to the power strip. Longer runs mean tighter cords that can loosen when rotating the TV or when moving it around. You can always unplug the power cord from the TV and plug it back in to ensure it is fully inserted and secure.

If checking the remote for functionality, testing the TV’s power source (outlet), and inspecting the TV’s power cord doesn’t solve the problem, there is one more thing you can try to resolve the issue.

Step 4: Power Cycle Your Vizio TV

If you suspect that you might be having power-related issues, the first solution to try is power cycling your Vizio TV. The process involves using the power button on your TV. Do Vizio TVs have buttons? In short, all buttons are found on the back and vary based on the model or version.

The process of power cycling your Vizio TV is straightforward and goes like this:

  1. Unplug the cord of your TV from the outlet and leave it disconnected.

  2. Locate the power button on the back of your your Vizio TV. The buttons blend in well, so you’ll need to look closely.

  3. Press and hold the button on your TV for about 10 seconds to drain any reserve energy.

  4. Try turning on your TV again.

The preceding steps are likely to work in many cases. If none of the procedures work the first time, try again, making sure to hold the power button down for at least 10 seconds each time. Often, this will be enough to fix your TV so that you can get back to relaxing.

Step 5: Call Vizio Customer Support

If none of the above tips work for you, it might be time to give Vizio customer support a call. They may provide steps for your particular Vizio TV model.

Calling tech support may fix the problem, but there might be some other issues with your TV that you can’t fix yourself.

The Vizio customer support team may be able to help you solve the problem by working with you over the phone or by telling you how to send in your TV for repair.

Step 6: Replace Internal Components

If you understand electronics and how they work, you can troubleshoot the boards to identify potential power problems.

A Vizio TV that won’t turn on is often caused by a failing power supply board. The most common parts to fail on a power supply board are capacitors, transistors, and diodes.

If the Vizio TV does have proper power outputs, but it’s appearing to not turn on, then the likely culprit is a bad T-Con board. In short, the Timed Controller Board is responsible for relaying signals to the LCD or LED screen. There’s more to it, but that’s the gist.

If you have never disassembled a Vizio TV or any other TV for that matter, it is best to let a certified repair technician handle the repairs for you. Disassembly is very precise, detailed, and a risk to your safety! Any wrong move, and you can damage the TV or yourself, especially with all those tight and brittle wire connections and high-power circuits.

TVs and the Power of Troubleshooting

Knowing what something isn’t doing, a TV not turning on in this case, is important in determining what the problem is. From there, you identify the reasons why the problem would arise. As you probably already know, start with the solutions and then go to the more advanced ones.
