Try the following troubleshooting remedies to fix your Hisense Smart TV flickering lines on the screen and other streaming issues on your TV unit.

Restart Your Hisense Smart TV

Flickering might be triggered by technical glitches, bugs, or TV overheating. To resolve this, disconnect the Hisense TV cable, wait for 5 minutes, and then restart it. This simple action often fixes the problem.

Check HDMI Cables

Problem: Flickering Due to Loose or Damaged HDMI Cables

If you notice flickering when switching your TV input from the home screen, the issue could be with your HDMI cable. A loose connection or dust in the HDMI port can cause this problem. Disconnect the HDMI cable, clean the port, and then reconnect the cable firmly. If the cable is damaged, replace it by buying a new HDMI cable from Amazon to solve the issue.

Configure Picture Settings

Problem: Flickering Due to Incorrect Picture Settings

Each Media content has varying resolutions and refresh rates. If your TV settings do not align with these, you may see pixelation and ghosting issues. Resetting the Picture settings on your Hisense TV can resolve this:

Hisense Android TV: To reset your Hisense Android TV’s picture settings, navigate to Settings, then select Device Preferences. From there, go to Picture and choose Reset to Default.

Hisense Roku TV: Select Settings, then System, and then About. Proceed to Advanced System Settings and choose Factory Reset. Select Reset TV audio/picture settings, and press the Play/Pause button three times to complete the process.

Hisense VIDAA TV: Click on Settings, navigate to Picture, and select Restore Default Picture Settings. That’s all you need to do.

Hisense XClass TV: To reset picture and sound settings on a Hisense XClass TV, go to Settings, then select Picture and Sound. Choose the Reset picture and sound settings option, and you’re done.

Additionally, turn off the energy-saving mode on Hisense TV under Settings → Picture → Picture Mode → Energy Saving → Turn it off, as it might also cause flickering.

Updating the Hisense TV to the latest firmware can fix flickering issues. Outdated firmware might not handle new video signals and upgraded applications properly, leading to flickering. Ensure your TV firmware is up-to-date and check if the issue is resolved.

Check for Hardware Issues

Problem: Flickering Due to Hardware Problems

Solution: Check for Hardware Issues

Flickering lines might result from issues with the T-CON board, circuit failure, backlight strip damage, or main board problems. Avoid attempting physical fixes yourself. Instead, contact Hisense TV Support to consult a technician to diagnose and repair the hardware issues properly.
