01Check the Cable Connections

  • Start by checking the cable connections between your TV and the video source. Ensure that all cables are securely plugged in and not loose.
  • If you are using HDMI cables, try unplugging them and plugging them back in to ensure a secure connection.
  • Inspect the cables for any signs of damage or fraying. If you notice any issues, replace the cables with new ones.
  • If you are using a set-top box or external device, make sure the cables connecting it to the TV are also properly connected and functioning.
  • After checking the cable connections, turn on the TV and check if the lines are still present on the screen.

02Reset the TV

  • Sometimes, a simple reset can resolve issues with the TV's display. To reset your TV, follow these steps:
  • Turn off the TV and unplug it from the power source.
  • Wait for at least 5 minutes to allow any residual power to discharge.
  • Plug the TV back in and turn it on.
  • Check if the lines on the screen have disappeared after the reset.

03Adjust the Picture Settings

  • If the lines on the screen persist, you can try adjusting the picture settings on your TV. Here's how:
  • Access the TV's settings menu by pressing the 'Menu' button on your remote control.
  • Navigate to the 'Picture' or 'Display' settings option.
  • Look for options like 'Picture Mode', 'Sharpness', or 'Contrast'.
  • Try adjusting these settings to see if it improves the display and removes the lines.
  • You can also try restoring the TV's default settings if you have made previous changes.
  • After making the adjustments, check if the lines on the screen have been fixed.

04Update the TV Firmware

  • Outdated firmware can sometimes cause display issues on a TV. To update the TV's firmware, follow these steps:
  • Check the manufacturer's website for any available firmware updates for your TV model.
  • Download the firmware update file onto a USB drive.
  • Insert the USB drive into the USB port on the TV.

  • Select 'Update Firmware' or a similar option, and choose the USB drive as the source.
  • Follow the on-screen prompts to complete the firmware update process.
  • After the update is finished, check if the lines on the screen have disappeared.

05Contact Technical Support

  • If none of the above methods have resolved the issue, it is recommended to contact the TV manufacturer's technical support for further assistance.
  • Provide them with the details of the problem, the steps you have already taken, and the model information of your TV.
