It is always disheartening when your Samsung TV suddenly stops working or gives you problems. It’s the last thing we want regarding our technology, but it does happen. One issue you may face is getting vertical lines on your Samsung TV.

Depending on the cause, it should be pretty simple to fix the picture on your Samsung TV. You just have to run a few simple tests to learn the cause, and it should be good as new.

This isn’t always the case, but once you know the cause, it will be easier to figure out what you need to do moving forward. Here is everything you need to know.

How To Fix A Samsung TV With Vertical Lines On Screen?

Fixing your Samsung TV can be simple. You just need to follow a few steps once you figure out the cause of those lines. There are some cases where it could malfunction hardware, but we will get to that later in this article. Here are these steps to follow:

  1. Find the cause.
  2. Complete a picture test.
  3. Book a technician.

Find The Cause

Before running the tests, you want to ensure if the cause is a part of a bad connection via one of the HDMI cords. If the lines are moving across the screen, one of the connections is not working or malfunctioning.

You don’t have to run any tests to fix this. Try changing the input channel on your television. If the vertical lines disappear, it has to do with the input of whichever one is making the lines. Try replacing the HDMI cords or the device itself to see if it fixes the problem.

If the lines continue showing up as you change inputs, then the cause of your lines could even be something as simple as a nearby device. If you think it started when you placed a device close to it, try removing it. If the lines disappear, then you can go ahead and watch your TV.

Complete A Picture Test

You can complete a picture test to see if it will fix the problem at hand. Just go to the menu screen and click on “picture test.” Run the picture test to see if it can figure out what is causing this issue.

To complete the test, ensure that you select “self diagnosis” and then run the test. It should take just a few minutes to run the test. It will then let you know what is the cause for the lines on your screen.

If your lines sometimes go away or disappear during the test, this is something that can be fixed by a technician. If it doesn’t go away then you may need to invest in a new television.

Book A Technician

If you are a tech savvy person, you can buy the parts that need to be replaced. It could be anything from an LED light within your TV or something more complicated like the Tcon. There are many ways to fix it yourself, but if you aren’t good with technology, book a technician.

What To Do If Nothing Works?

If nothing works, it may be a part that has malfunctioned. If your TV is older, this could be it as technology should be replaced every few years to replace any of the old technology that has become outdated.

At this point, you should have a technician take a look. This is if you would like to try and restore your TV without spending the amount on a brand new TV. But if it has been a few years, it may be in your best interest to just replace the TV because parts and labor can get expensive.

Check Your Warranty

If you have a newer TV, sometimes the companies have automatic warranties on the television, especially if it is within the first year of owning it. Check with the company to see if your TV is under warranty and it may save you a good chunk of money. You don’t want to spend too much when you already forked up a lot for the TV in the first place.

Check For A Recall Notice

Always check to see if a company has recalled your television. Sometimes a bad batch of products goes out, and the company will replace the bad batch. You may be saving yourself quite a bit of money, especially when your TV is on the list.


It sucks when your television gets vertical lines. It takes away from the experience of watching your favorite movies and shows. Try these simples steps to see if you can find the cause or if it is fixable. You can always try a technician but it may be better to just get a new one.
