Fixing the Flicker: A Step-by-Step Guide
Top Solutions
Perform a power cycle on your TV. A simple glitch may be responsible for the flickering issue.
- Turn off your TV, unplug it from the power source, and wait for at least 30 seconds.
- Reconnect the power and turn the TV back on to see if the flickering has stopped after the reset.
Inspect your cable connections. Loose or damaged cables can lead to screen flickering. Make sure all cables are securely connected and that none are visibly damaged.
- If you have a modern Samsung TV, you can use its built-in diagnostic tool to check cable status. Navigate to Settings > Support > Device Care > Self Diagnosis > HDMI Troubleshooting for an easy check.
Update your software. Outdated firmware can be a culprit behind the flickering display, so ensure you are running the latest software version.

Clean your TV screen. Dust and debris on the surface of your TV can interfere with its performance, causing issues like flickering.
- Use a microfiber or lint-free cloth to gently clean the screen and remove any dirt or buildup. You can also refer to this guide on proper TV cleaning.
Check if your TV is overheating. An excessively hot TV can struggle with performance and may cause issues like flickering.
- If your TV feels hot to the touch, it could be due to inadequate ventilation or a malfunctioning fan. Make sure your TV is positioned in a well-ventilated area.
- Allow the TV to cool down by turning it off for a while before attempting to use it again.
Examine the refresh rate. The refresh rate determines how many frames your TV can display per second. If the rate is too high, it can cause flickering.
- Check your TV's display settings or picture options and make sure the refresh rate isn’t set too high.
Reset your TV to factory settings. This will restore your TV to its original settings and might solve the issue. Keep in mind that resetting your TV will erase all personal data, settings, and apps, including Wi-Fi credentials.
