01Check the Cable Connections

  • The first step in fixing a TV with horizontal lines is to check the cable connections.
  • Make sure that all cables, including the HDMI, coaxial, and AV cables, are securely plugged into the appropriate ports on both the TV and the external devices.
  • If any of the cables are loose or damaged, try replacing them with new ones.
  • Sometimes, loose or faulty cable connections can cause horizontal lines on the screen.
  • Once you have checked the cable connections, power on the TV and check if the lines are still present.

02Adjust the Screen Resolution

  • If the horizontal lines persist, the next step is to adjust the screen resolution.
  • On your TV's settings menu, navigate to the display settings.
  • Look for the screen resolution option and try reducing it to a lower value.
  • Sometimes, high screen resolutions can cause compatibility issues and result in horizontal lines on the screen.
  • After adjusting the resolution, check if the lines have disappeared.

03Update the Firmware

  • Outdated firmware can also cause display issues including horizontal lines.
  • Check the manufacturer's website for any available firmware updates for your TV model.
  • Download the latest firmware onto a USB drive and follow the instructions provided by the manufacturer to update the TV's firmware.
  • Updating the firmware can often resolve various issues, including horizontal lines on the screen.
  • After updating the firmware, check if the lines have been resolved.

04Reset the TV to Factory Settings

  • If the previous steps did not fix the issue, you can try resetting the TV to its factory settings.
  • Go to the settings menu on your TV and look for the reset or restore option.
  • Select the option to reset the TV to its original factory settings.
  • Keep in mind that this will erase any saved settings or preferences, so be sure to back up any important data beforehand.
  • After the TV has been reset, check if the horizontal lines are still present.

05Contact a Professional Technician

  • If none of the previous steps have resolved the issue, it may be necessary to contact a professional technician.
  • There could be an underlying hardware problem causing the horizontal lines on your TV.
  • A technician will have the expertise and equipment to diagnose and fix the issue.
  • Be sure to consult your TV's warranty or contact the manufacturer for any available repair options.
