Is your Vizio sound bar refusing to turn on, leaving you with a silent and frustrating viewing experience? You’re not alone! In this comprehensive guide, we’ll walk you through a series of troubleshooting steps to help you diagnose and fix the issue with your Vizio sound bar.
Before We Begin: Power Cycle and Restart
Before we dive into the more complex troubleshooting steps, let’s start with the simplest solution: a good old-fashioned power cycle. This often-overlooked step can resolve many issues, including a sound bar that won’t turn on.
To power cycle your Vizio sound bar:
- Unplug the power cord from the back of the sound bar.
- Wait for 30 seconds to allow any residual power to drain.
- Plug the power cord back into the sound bar.
- Try turning on the sound bar using the remote control or the power button on the unit.
If your sound bar still refuses to turn on, it’s time to move on to more advanced troubleshooting steps.
Troubleshooting the Power Source
A faulty power source can be a common culprit behind a sound bar that won’t turn on. Let’s investigate the power source to see if it’s the root of the problem.
Check the Power Cord
The power cord is the most vulnerable part of the power source chain. Check the cord for any signs of damage, such as:
- Frayed or exposed wires
- Cuts or nicks in the insulation
- Bent or pinched pins on the plug
If you find any damage, try replacing the power cord with a new one. If you’re using a surge protector or extension cord, try plugging the sound bar directly into the wall outlet to rule out any issues with the intermediate power sources.
Check the Wall Outlet
Ensure the wall outlet is working properly by plugging in another device, such as a lamp or phone charger, to verify it’s receiving power. If the outlet is dead, you may need to reset the circuit breaker or replace a blown fuse.
Troubleshooting the Sound Bar Itself
Now that we’ve ruled out the power source, let’s focus on the sound bar itself.
Check the Power Button
The power button on your Vizio sound bar might be faulty or stuck. Try pressing the power button for an extended period (around 10-15 seconds) to see if it turns on. You can also try unplugging the sound bar, pressing the power button for 30 seconds to discharge any residual power, and then plugging it back in.
Check for Faulty Capacitors
Capacitors in the sound bar’s power supply unit (PSU) can fail over time, preventing the sound bar from turning on. While this is a more advanced troubleshooting step, you can try checking for signs of capacitor failure, such as:
- Bulging or leaking capacitors
- Burn marks or signs of overheating around the capacitors
If you suspect faulty capacitors, it’s recommended to consult a professional for assistance, as repairing or replacing them can be a complex task.
Firmware Issues and Resets
Firmware problems or corruption can cause your Vizio sound bar to malfunction or refuse to turn on. Let’s try resetting the sound bar to its factory settings or updating the firmware.
Resetting the Sound Bar
To reset your Vizio sound bar, follow these steps:
- Press and hold the VOL- and VOL+ buttons simultaneously on the sound bar or remote control.
- Hold the buttons for 5-10 seconds until the LED lights on the sound bar start flashing.
- Release the buttons and wait for the sound bar to complete the reset process.
Note that resetting the sound bar will erase all customized settings, so you’ll need to reconfigure them after the reset.
Updating the Firmware
Visit the Vizio website to check for any firmware updates for your sound bar model. Follow the instructions provided to download and install the update. Make sure to follow the correct procedure, as incorrect firmware updates can cause more harm than good.
Additional Troubleshooting Steps
If none of the above steps have resolved the issue, it’s time to get a bit more creative.
Check for Physical Obstructions
Ensure there are no physical obstructions blocking the sound bar’s vents or air intake. A clogged or blocked sound bar can cause it to overheat, leading to a failure to turn on.
Consult the User Manual
Review your Vizio sound bar’s user manual to ensure you’re following the correct procedures for turning it on. You might have overlooked a specific step or setting that’s preventing the sound bar from functioning.
When to Seek Professional Help
If you’ve exhausted all the troubleshooting steps above and your Vizio sound bar still refuses to turn on, it’s likely that the issue is more complex and requires professional assistance.
Consider contacting Vizio’s customer support or visiting an authorized service center for further diagnosis and repair. They’ll be able to assess the issue and provide a more detailed course of action to get your sound bar up and running again.

Why won’t my Vizio sound bar turn on?
The most common reason why a Vizio sound bar won’t turn on is a power issue. This can be due to a faulty power cord, a blown fuse, or a tripped circuit breaker. It’s also possible that the sound bar’s internal components have failed, preventing it from receiving power. To troubleshoot the issue, try plugging the sound bar into a different outlet or checking the circuit breaker to ensure it hasn’t tripped.
If none of these solutions work, it’s possible that the sound bar’s internal components have failed, and it may need to be repaired or replaced. In this case, it’s recommended to contact Vizio’s customer support or a professional repair service to diagnose and fix the issue.
How do I reset my Vizio sound bar?
To reset your Vizio sound bar, press and hold the “Volume Down” button and the “Input” button simultaneously for at least 10 seconds. This will restore the sound bar to its factory settings and may resolve any software-related issues that are preventing it from turning on. After resetting the sound bar, try turning it back on to see if it’s working properly.
It’s important to note that resetting the sound bar will erase all of its stored settings and preferences, including any paired devices or customized audio settings. This means you’ll need to set up the sound bar again from scratch, including pairing it with your TV or other devices and reconfiguring any custom audio settings.
What if I’ve tried everything and my Vizio sound bar still won’t turn on?
If you’ve tried all of the troubleshooting steps and your Vizio sound bar still won’t turn on, it’s likely that the issue is hardware-related and requires professional repair or replacement. In this case, it’s recommended to contact Vizio’s customer support or a authorized repair service to diagnose and fix the issue.
They will be able to diagnose the problem and provide a quote for repair or replacement. In some cases, it may be more cost-effective to purchase a new sound bar, especially if the repair cost is close to the price of a new unit.
Can I fix a blown fuse in my Vizio sound bar?
If you’ve determined that a blown fuse is the cause of your Vizio sound bar not turning on, it may be possible to fix it yourself. You’ll need to locate the fuse on the sound bar’s circuit board and replace it with a new one of the same amperage rating. However, this can be a delicate process, and you’ll need to be careful not to damage any of the surrounding components.
It’s recommended to seek the help of a professional if you’re not comfortable with DIY repairs or if you’re unsure about how to replace the fuse. Additionally, if the blown fuse was caused by a underlying issue, such as a power surge or electrical short, you may need to address that issue as well to prevent it from happening again.
How do I know if my Vizio sound bar is still under warranty?
To determine if your Vizio sound bar is still under warranty, you’ll need to check the warranty information that came with the product or contact Vizio’s customer support. The warranty period typically ranges from one to two years, depending on the specific model and purchase date.
If your sound bar is still under warranty, you may be eligible for free repair or replacement. Be sure to have your proof of purchase and warranty information ready when you contact customer support.
Can I use a different power cord with my Vizio sound bar?
