Is your 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 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Rule out a glitch by power cycling your TV, then make sure you're not running outdated, buggy software by updating your TV.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.

Best Fixes
-
Power cycle your TV. 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.
-
2Check your cable connections. 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.
- Some TVs, like modern Samsungs, have a self-diagnostic tool that you can use to check the status of your cables. Go to Settings > Support > Device Care > Self Diagnosis > HDMI Troubleshooting . [1] X Research source

4Wipe off your TV. Dust and debris build-up can cause electrical issues with your TV, including a flickering screen.
- Use a microfiber or lint-free cloth to lightly clean your TV .
-
5Check if your TV is hot. 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 so it can cool down before trying to use it again.
-
6Check the refresh rate. The refresh rate controls how many frames you see in a moment. The higher the refresh rate, the more frames are displayed every second. Many TVs have adjustable refresh rates, and if it's set too high, the screen will flicker.
- Go to your TV's display settings or picture options to find the refresh rate. Make sure it's not set too high.
-
7Reset your TV to factory settings. This will return your TV to the original settings, which may solve the problem. However, factory resetting any device means you'll erase your TV's personal data, settings, and customizations. That includes Wi-Fi names and passwords as well as downloaded apps.

8Contact a repair professional. Hardware, instead of software, might be causing the issue. Not all hardware is repairable, but for some, you need to call professionals to fix.
- If your TV is newer or still under warranty, contact the manufacturer for a repair. It might be free!
-
9Buy a new TV. 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!
