Samsung TV Horizontal Lines on Screen (Try This FIRST!)

Now that we know about what causes horizontal lines on your TV screen and Samsung device, there are some easy fixes! Here are seven quick Samsung TV horizontal lines fixes. If you have a vertical line issue, these fixes are still effective.

1. Power Cycle the TV

The quickest and easiest thing you can do is power cycle your television. When dealing with a single vertical line on your Samsung TV, it’s almost certainly a software glitch. Software glitches sound daunting, but they’re arguably the easiest issue to fix!

Software glitches often arise from snags and issues in the television’s software. Power cycling your television will force your television to shut down. Ending all processes in this manner often fixes glitches.

Unplug your television from its power source. Hold the power button down for 30-60 seconds. Doing so will force the power to drain from your television.

Once you’re done, plug the television back in. Start the television up as you usually do and see if this fix worked. If not, you may have a more elaborate problem.

2. Reseat HDMI Connections

One of the other easy methods is to reseat your HDMI connections. In technological terms, “reseat” means to disconnect and reconnect. Doing so can help fix small snags or glitches by forcing the connection to start from scratch.

Unplug your HDMI cord from your television and its video source. Plug the cord back in and see if the problem remains. Consider plugging the cord into a different HDMI port if you still have the lines. You also should consider replacing the cord.

3. Return Under Warranty

You should return the device to Samsung if your television is still under warranty. Your warranty is meant to protect you from these glitches and issues. Contact Samsung and say that you want to claim your warranty.

Contact the retailers you purchased the television from as well. Retailers like Wal-Mart or Best Buy may offer individual warranties. In this case, you fulfill your warranty with the retailer instead of Samsung.

4. Remove the Back Panel & Clean Your Television with Compressed Air

A quick physical fix is to remove the back panel of your television. Here, you’ll likely find dust and detritus. The vents in the back of your television can suck in debris and cause issues such as overheating.

Use compressed air to blow this area clean. You can purchase a can of compressed air online or at most office supply retailers. Be careful not to hold the can upside down or sideways, as this can send liquid propellant into your electronics and cause damage.

5. Reseat T-CON Board Ribbons

The T-CON board is a crucial component of your computer. You should consider reseating the ribbons the same way you reseat the HDMI cords. Unplug these ribbons and plug them back in.

The ribbons are fragile and prone to breaking if handled incorrectly. If you aren’t comfortable manipulating them, contact a technician.

6. Block Specific Ribbon Strip Contact Points With a Piece of Tape

Your T-CON board’s ribbons may contact points that you don’t want them to. The contact points may have faulty connections or prove unnecessary. In this situation, you should block those points with a piece of electronics-safe tape. Doing so may fix your line issue.

7. Contact Samsung Support

If all else fails, you should contact Samsung support. Samsung’s representatives can help you troubleshoot, return the television, or book a technician. You can also begin the process of purchasing a new television if yours needs replacing.

How Do I Fix Ghosting on My Samsung TV?

On a television, “ghosting” is when the image is inexplicably doubled. To fix this issue, you should update the firmware of your Samsung television. 

You can update your TV’s firmware from the Settings menu, but you will require an internet connection. Otherwise, use a USB thumb drive to download the firmware from Samsung’s website.

How to Remove Colored Vertical Lines All Over the Screen of My LED TV?

Your first step is to diagnose why the issue is occurring. Consider power cycling your television to solve most simple software glitches. You should also check physical connections such as your HDMI cords or other video connections.

Thin Black Line on Samsung TV Screen

Once you’ve diagnosed the issue, you can begin fixing the problem. A black line is a signature symptom of overheating. Remove the back panel of your television and see if you have a dust clog or other debris.

If you find debris, use compressed air to blow the dust away. Don’t use harsh materials like paper towels or fabric. If you must use fabric, use a safe and gentle fabric like a microfiber cloth.

Single Vertical Line on Samsung TV

If reseating, power cycling, and cleaning the back of your computer don’t work properly, consider a factory reset. A factory reset will force your television back to its default settings. While this sounds inconvenient, it also will fix nearly any software glitch or issue.

Grey Fog and Black Vertical Lines Again After Repair

Contact the repair service if you have your television repaired and there are still issues. They may have failed to fix your television properly or caused a smaller issue inadvertently. 

You could also have unfixable damage to the hardware of your television. In such a situation, it’s often best to replace the television. Contact Samsung about your warranty and have the television replaced.


Dealing with Samsung TV problems like lines on your screen is obnoxious but easy to fix. Consider reseating your cords, power cycling, or a factory reset. In more extreme cases, reseat your T-CON board or contact professional technicians.
