A common problem that some Samsung LED TV owners have had to deal with is vertical lines, horizontal lines, or ghosting in the picture on their TV. They can appear as colored or black lines or images resembling double (or triple or more) exposure in a picture, where images overlap. Regardless of what you’re seeing, there are some things you can try to fix the problem.

Causes of Vertical Lines on a Samsung LED TVĀ 

There are typically two causes of vertical lines on a Samsung LED TV: a bad connection or a processing problem. If the problem is a bad connection, you can likely fix it yourself using the troubleshooting steps below.

However, if the problem is a processing issue, that means you could have a faulty processing board, scalar PCB, T-Con, or Cof-IC, in which case a professional will need to inspect and repair your television.

Loose or incompatible connections can also cause ghosting. Still, it’s also possible you’re having antennae issues or, as with vertical lines, you have a bad component inside the TV that a professional will need to repair.

How To Get Rid of the Vertical Lines on My Samsung TV

1. Check cable connections: Start by inspecting the connections between your TV and the video source (such as cable box, game console, or streaming device). Make sure the cables are securely plugged into the correct ports on both the TV and the device.

2. Restart the TV and connected devices: Power off the TV and any connected devices, unplug them from the power source, and wait for about 10-15 minutes. Then, plug everything back in and power them on. This can help resolve temporary glitches and refresh the connection.

3. Check for software updates: Ensure that your Samsung TV’s firmware is up to date. You can check for updates by going to the TV’s settings menu and looking for the software/firmware update section. If an update is available, follow the on-screen instructions to install it.

4. Adjust picture settings: In some cases, adjusting the TV’s picture settings may help reduce or eliminate the vertical lines. Access the picture settings menu on your Samsung TV and try the following:

  • Disable or modify settings like “Digital Clean View,” “Auto Motion Plus,” or any image-enhancing features that may be causing interference.
  • Reset the picture settings to default values and see if the issue persists.

5. Run built-in TV diagnostic tools: Some Samsung TVs have built-in diagnostic tools that can help identify and fix display issues. Check your TV’s user manual or the Samsung support website for instructions on accessing and running diagnostic tests specific to your model.

6. Test with different inputs and sources: Connect different devices (such as a DVD player, game console, or another streaming device) to the TV using different cables and test if the vertical lines appear with all inputs. If the lines are present regardless of the input or source, it indicates a potential hardware issue with the TV itself.

7. Contact Samsung Support: If none of the above steps resolve the vertical lines issue, it’s recommended to reach out to Samsung customer support or consult a professional technician for further assistance. They can provide specific guidance based on your TV model and help determine if any repairs are required.
