Is your Vizio TV screen flickering? Fortunately, there are a few troubleshooting steps you can take at home before calling a professional or buying a new TV. Follow this guide to fix your flickering monitor yourself.

Causes & Fixes for a Flickering Vizio TV

Rule out a glitch by power cycling your TV, then make sure you're not running outdated, buggy software by updating your TV. Loose cables and dust build-up can also cause flickering screen issues, so ensure your connections are tight and wipe your TV with a microfiber cloth.

  1. A glitch might be causing the TV to flicker.
    • Start with the TV powered off, then unplug it from power for at least 30 seconds.
    • Plug it back in and turn it on to see if a simple power cycle worked.
  2. A loose cable can cause your screen to flicker. Check that any cables are connected tightly at each port and that they don't have visible damage.
    • For example, Vizio SmartCast Displays have awesome HDR capabilities as long as your HDMI cable is tightly connected to both ports and isn't damaged. You want to make sure you're using an HDMI 2.0 cable since the older 1.4 cables can cause the screen to flicker.
    • While you're checking for any signs of damage or wear in your cables, you also want to disconnect and reconnect them to make sure they are securely connected.

  3. Go to Vizio's advanced video settings and look for "Ambient Lighting,", "Backlight Control," or "Advanced Adaptive Luna."
    • If any of these are on, turn them off and see if the flickering improves at all. [1]
  4. Outdated software can cause your screen to flicker, so you want to make sure you're using the latest update available.
    • Press the "Menu" button on your remote and go to Admin & Privacy > Check for Updates . Any unapplied updates will automatically download and install as your TV restarts. [2]
  5. Dust and debris build-up can cause electrical issues with your TV, including a flickering screen.
  6. A TV that's overheating is working too hard and can cause electrical issues, including flickering.
    • If the TV feels very hot when you touch it, a fan might not be working to circulate air properly, or you may have the TV improperly placed in an area without ventilation.
    • Turn the TV off for a while to cool down before trying to use it again.
  7. Press "Menu" on your remote and go to Picture Settings . From there, you can select a different picture mode, which might solve your flickering issue, or you can reset all the settings in More > Reset Picture Mode .
  8. This will return your TV to the original settings, which may solve the problem. However, factory resetting any device means you'll erase your personal data, settings, and customizations. That includes Wi-Fi names and passwords as well as downloaded apps. [3]
    • Vizio SmartCast TV : Press the "Menu" button on your remote and go to Admin & Privacy > Reset to Factory Settings > Enter a PIN > Reset/OK .
  9. Vizio's customer support may be able to help you more than you can do on your own. You can contact Vizio on their support page .
  10. If repairing your TV didn't work or if the repair costs more than a new TV, this is the best option for you. Older TVs are less economical and offer fewer features than modern TVs, which might be a bonus.
    • If your malfunctioning TV is newer and still under warranty and can't be fixed, you might be able to get a free replacement!
