Why Is My Vizio TV Light Fading?

I am the proud owner of a Vizio TV, but recently I’ve been noticing that the light on the TV is starting to fade. It’s not something that I can ignore, and it’s been really frustrating me. I’ve done some research and experimented with some tips and tricks to see if I can solve the issue, and I’m here to share the journey with all of you. In this blog post, I’ll be discussing why my Vizio TV light is fading and what I did to try and solve the problem. I’ll also be sharing some of the other solutions I discovered from other owners who had the same issue.

A fading TV light is often caused by display settings issues, faulty HDMI, and problems with external devices. It’s also possible that your Vizio TV has a broken light in the lighting panel. Luckily, this can be fixed by correcting your settings, power cycling, and checking your external devices and cables.

What Causes Vizio TV Light to Fade?

There are many possible causes for TV lights to fade or dim. In most cases, it’s only a display glitch or an issue with the TV’s picture settings.

The common causes of fading Vizio TV light include:

  • Faulty HDMI cables and ports
  • Problems with your connected external devices
  • Display or Picture Settings issues
  • Hardware issues, such as damages to the lighting panel

For the most part, these issues are easy to deal with and can be fixed in no time. If you’re looking at some hardware issues, it might be best to reach out to a professional or Vizio support.

Hardware issues may need you to open the TV and check its externals. We don’t recommend doing this on your own as it can be complicated, and you might further the damage.

It’ll also void your TV’s warranty, which you’ll need in case of a possible replacement. Try reaching out to a professional technician or Vizio support for serious hardware issues.

How to Fix Fading Vizio TV Light

As we’ve mentioned, there are a few easy troubleshooting steps to take to get this issue fixed. These are proven and trusted methods you can try before reaching out for help from a professional.

Here are some of the quickest fixes you can try to get the Vizio TV light issue out of the way:

Power Cycle Your TV

The first thing you can do for almost any common TV issue or glitch is power cycling. It’s a proven method that refreshes your TV and remedies most tech problems.

To get started:

  1. Unplug your Vizio TV’s power cord from its power source.
  2. Locate your Vizio TV’s power button, then press and hold it for 3 to 5 seconds.
  3. You can also try waiting for at least 15 seconds before plugging it back in.
  4. Plug your Vizio TV’s power cord back and check if the light is still dim or fading.

Try Using a Different Source or Input

For tech issues, such as fading TV lights, it’s best to isolate the issue to find out its root cause. One way to do this is by checking your other sources or inputs.

This helps determine if the issue is caused by the Vizio TV itself or an external device that’s connected to it.

To do this:

  1. Press the INPUT button on your Vizio remote.
  2. Toggle between the inputs and select your preferred option.
  3. If you’re using an external device as an input, try to switch to the TV.
  4. Check if the lights still fade on a different input.

Check Your HDMI Cables and Ports

If you’re watching through an external device connected to your TV, it’s worth checking the HDMI cables and ports. You may be experiencing display issues because the cables and ports are either damaged or dirty.

To get started:

  1. Unplug the HDMI cable from its port.
  2. Scan for any damages to the wires and the ports.
  3. If you see any damage, try using a different cable or port.
  4. If they’re dirty, gently clean them off with a soft brush or damp cloth.
  5. Plug them back in to check if the issue persists.

Turn Off the Vizio TV’s Auto Brightness Control

Another way to make sure you don’t have a dim screen is by turning off the Auto Brightness Control. After that, try to adjust your TV’s Brightness, Backlight, and Contrast accordingly.

To do this:

  1. Head to the Menu or Settings and select Picture.
  2. Turn off the Auto Brightness Control settings.
  3. Adjust the Brightness, Backlight, and Contrast in the same menu until the screen is visible.

Run a Factory Reset on Your Vizio TV

If all else fails, it’s worth trying to factory reset your Vizio TV. Just remember that this clears all saved data so you’ll have to set everything back up after.

To factory reset your TV:

  1. Press the Menu button, then select System.
  2. Select Reset TV to Factory Defaults.
  3. Enter your parental code (if you haven’t set this up, use ‘0 0 0 0’).
  4. Boot it up after to check if the issue persists.

Conclusion

Fading Vizio TV lights is nothing to be worried about and can be easily fixed most of the time. As long as you’re sure that there are no hardware damages, it’ll only take a few troubleshooting.

It’s also a good idea to take good care of your devices and their equipment to avoid these issues. Prevention is always better than cure.
