Vizio TV Power Board Symptoms

Vizio is a well-known TV brand with a variety of TV models that provide great performance. Each television model has its price range and distinguishing characteristics.

However, there appears to be a prevalent flaw with Vizio televisions. Many Vizio owners complain about their television not turning on. This problem can be upsetting, especially when it’s time to watch your favorite show and your TV won’t turn on.

Fortunately, there are simple solutions to this problem, and this article will offer them.

It might be incredibly annoying if your Vizio TV suddenly fails to turn on. Purchasing a new television may be pricey and having one fixed can be both costly and time-consuming. But don’t be concerned. There’s no need to fear if your Vizio won’t turn on. 

There are a few plausible explanations for why the scenario happens, and in most situations, it is not due to a faulty television. It usually just takes a few minutes and some tinkering to get your TV up and running again.

It might be quite inconvenient if your Vizio TV unexpectedly fails to turn on. A new television may be costly and having one repaired can be both costly and time-consuming. But don’t be alarmed. There’s nothing to worry about if your Vizio won’t turn on. 

There are several logical theories for why the scenario occurs, and in most cases, it is not the result of a defective television. It normally just takes a few minutes and some fiddling to get your TV back up and running.

If your Vizio LED/LCD flat-screen exhibits the following symptoms: 

  • no graphics on the screen 
  • no sound coming from the speakers 
  • HDMI not working properly,
  • If you’re having trouble connecting to the Internet

You may have a defective mainboard, as these are frequent main board symptoms on Vizio TVs. The video below provides step-by-step directions for replacing the mainboard appropriately. The video was created by ShopJimmy, which is also one of our favorite TV repair stores where you can get tools and supplies for any TV repair project.

Why is my Vizio TV not turning on and the power light is fading?:

Does your Vizio TV not turn on when you use both the remote and the physical button? If this is the case, the IR receiver cannot be the source of the problem.

This leaves two options: a faulty power board or a faulty system board.

When unplugging and replugging your Vizio TV, keep an eye out for the TV power light. If it flashes on and off quickly, you’re getting power, thus the issue is most likely with your system board.

If, on the other hand, it does not turn on and off quickly, your power board may be faulty. Unplug and re-plug the device many times to test your findings.

You’ll need to disassemble your TV to address both concerns. You must obtain both the etched board model number and the sticker model number from your power or system board before purchasing an exact match.

You must exercise caution since Vizio TVs of the same model frequently have different components owing to product updates, so it is critical to obtain an exact match.

Check the Power Cord:

If your TV power cable is not properly or loosely hooked into a power source, the TV connection may be affected. That example, a faulty or frayed power cord might create difficulties with the television. Check that the connection to the TV and the power socket are both completely and correctly plugged in.

It should be noted that a little slack connection on the power cable to the power source might disrupt the flow of energy to the TV, causing it to not turn on. To resolve this issue, disconnect the power cord from the back of the TV and then reconnect and plug it properly. 

Check that the power cord is securely connected to the TV.

Troubleshooting Caution:

Knowing what something isn’t doing, in this example, a TV not turning on, is critical in pinpointing the source of the problem. Then you figure out why the problem occurred in the first place. As you are surely aware, you should begin with the simpler solutions and work your way up to the more complex ones.

Please keep in mind that the symptoms listed above might be caused by something else, so proceed with caution during the troubleshooting procedure. For example, if there are no images on the screen, you should check to see whether there is an issue with the LED backlights. You should run the “flashlight test” to determine whether the LCD panel is producing images, but the backlights are not working. 

This test was carried out to fix a Vizio TV that had sound but no visuals (you may want to check that out). Given that the TV lacks sound, there’s a fair chance that the problem isn’t caused by malfunctioning LED backlights, but it never hurts to double-check.

Furthermore, if you are having trouble connecting to the Internet, you should first check to see if there are any difficulties with your network before blaming your Vizio’s mainboard. First, you should verify the connection of your Wi-Fi router. 

A similar procedure was followed, as explained in our piece on troubleshooting Netflix on a Samsung Smart TV. You should connect your TV to the Internet using an ethernet wire to rule out the chance that your Wi-Fi network is malfunctioning.

As always, if you have any doubts about this repair, please do not hesitate to seek expert assistance.


Hopefully, after doing one of the above methods, your television is now turned on.

If your TV is still not working, it has a problem that has to be fixed. Contact Vizio to see if your TV may be repaired under warranty. Although the satellite dish may have been damaged, a Vizio technician may provide rooftop services. A technical support representative will discuss your alternatives for repairing your television.

As previously stated, your Vizio TV may not come on for a variety of reasons. If you attempt all of the above suggestions and your TV still does not come on, there might be a problem with the internal components of the TV. This is a technical problem, and you may need to call an expert to disassemble and repair it.

You can also contact Vizio customer service. They are in the best position to assist you in resolving the problem or, in the worst-case scenario, to collect and repair the television for you.
