Have you ever settled in to watch your favorite show on your Vizio TV, only to be interrupted by a high-pitched whining or squealing noise from your television set? If so, you’re not alone. Many Vizio TV owners have reported experiencing this issue. In this article, we’ll explore the possible causes of this problem and provide some solutions to help you eliminate that annoying sound.
First, let’s talk about what this high-pitched noise sounds like. Some Vizio TV owners describe it as buzzing, while others liken it to a hissing or whistling sound. Whatever the sound, it can be incredibly frustrating, especially if you’re trying to enjoy your favorite shows or movies.
Why is it happening?
There are several reasons why your Vizio TV might be making this noise. One of the most common causes is loose windings or cores in power inductors or transformers. This can happen due to age or wear and tear on the TV. Sometimes, this problem can be fixed by spraying the offending component with aerosol lacquer. If the noise only occurs when the set is turned off, it’s likely in the standby power supply.
Another potential cause of the high-pitched noise could be interference from other electronic devices in your home. This interference can cause a feedback loop that creates a high-pitched sound. This issue can sometimes be fixed by unplugging other devices from the same outlet or power strip as your TV.
So, how can you fix the high-pitched noise from your Vizio TV? Here are some steps you can take to try and eliminate the problem:
- Power Cycle the TV The first step is to power cycle the TV. Turn your TV off, unplug it from the power source, and hold down the power button on the TV for five seconds. Then, plug the power cord back in and turn the TV on. This can reset the TV and eliminate any temporary issues that may be causing the noise.
- Reduce the Backlight Setting in the TV Menu Another potential fix is to reduce the backlight setting in the TV menu. Press the Menu button on your Vizio remote, highlight the Picture settings option, select the Backlight setting, and turn it down. This can reduce the strain on the TV’s power components and potentially eliminate the high-pitched noise.
- Unplug All Devices Connected to Your TV. If the noise persists, try unplugging all devices connected to your TV. If the noise disappears, plug each device in one at a time and see if the noise returns. If the noise comes back when a specific device is plugged in, the problem is likely with that device and not your TV. In that case, contact the device manufacturer for further assistance.
- Contact Customer Support. If none of the above solutions work, it’s time to contact Vizio customer support. They can help troubleshoot the issue and provide additional support if needed.
