Anyone would be devastated if they woke up to see their brand new Samsung TV displaying vertical lines. While you might be paralyzed by the horror in front of you, worry not! Vertical lines may give you the impression that your TV is useless now waiting to be collected by the garbage truck; however, this issue is pretty easy to fix.
Vertical lines may be caused by loose connections with your HDMI cable or through a hardware issue induced inside your TV’s panel. You will need to remove the panel and clean it to remove any dust and tinker with the T-CON board (if that is the main culprit for the issue).
Dive into this article to explore the simple and technical solutions that might help you eradicate the vertical lines and bring your TV back to life!
What Causes Vertical Lines On Samsung TV?
There are a plethora of reasons that may cause vertical lines to appear on your Samsung TV. Let’s take a brief look at what they are to help you understand the fault better:
Cause 1: T-CON Board
T-CON board, also called the Timing control board, is a little piece of hardware embedded inside your TV whose purpose is to process the video that displays on your Samsung TV’s screen. To simplify, it is responsible for converting the video signals into one your LCD panel can understand, and if it starts acting funny, you’ll begin seeing vertical lines on your screen.
Cause 2: Accumulation Of Dust And Debris
Dust and debris can give birth to a wide range of issues on any electronic device, especially in TVs due to their large size. They get into the tightest of spots and hinder the functionality of many components which includes the ribbons responsible for giving video signals in the T-CON board.
I recommend you get your TV serviced once in a while so that it stays in top-notch shape and performs to the best of its ability.
Cause 3: HDMI connection
A faulty HDMI can induce many display problems inside a perfectly fine TV. If your HDMI cable is broken or has a loosened connection, it may cause vertical lines on your TV. I recommend getting an HDMI cable from a manufacturer whose products are known to last longer, so you don’t have to get into the hassle of purchasing one almost every week.

Fix 1: Soft Reset Your Samsung TV
Whenever we face some sort of glitch on our phones, our first instinct is to restart them. The same goes for any electronic equipment. Vertical lines may be caused by the software program inside, and giving your TV a restart will (in most cases) resolve the conflicting bugs that might be putting you through this trouble.
How To Soft Reset Your Samsung TV?
So how do you perform a soft reset on your Samsung TV? It’s simple really, just follow the steps below:
Step 1: Unplug your Samsung TV for a minute. Wait for 60 seconds before you begin step 2.
Step 2: After waiting for a minute, go to your TV’s power button and hold it for 30 seconds. Make sure you’re holding the power button of your TV and not the remote.
This method is different from just turning your TV on and off as it clears off any undrained energy from your TV that could be causing it to malfunction and produce vertical lines on the display.
Fix 2: HDMI Connection
Don’t be disheartened if the first method didn’t cut it out. Dust and debris can also accumulate inside your HDMI port which is the leading cause of your TV displaying vertical lines. There’s also the likelihood that your HDMI cable is faulty, and your TV is perfectly fine.
How To Fix Faulty HDMI Connection?
Disconnect each and everything your Samsung TV is connected to. Then replug the HDMI cable. If that didn’t seem to fix it, try plugging the HDMI cable into another port. You could also try using a different HDMI cable to see if it fixes the problem.
Fix 3: Picture Test
The picture test is a self-diagnosis method that can help narrow your options by letting you know if the vertical lines on your screen are caused by a hardware issue or cables connected to the TV.
Remember that if the vertical lines are caused on one side of the screen, you can still fix them. However, if they’re scattered through the screen, you might want to start considering getting a new Samsung TV.
How To Do The Picture Test?
The picture test requires you to navigate your Samsung TV’s settings and find the relevant option:
Step 1: Turn your TV on and press the Home button on your remote. Then select Menu.
Step 2: Go to Settings → All Settings → Support → Device Care.
Step 3: Your device will then do a quick scan. After the scan ends, click on Self Diagnosis.
Step 4: Select the Picture Test option. Click OK on the prompt that appears.
The picture test will begin. If the vertical lines seem to disappear in the test, then it’s a fixable hardware issue.

Fix 4: Cleaning the Back Panel
The following method requires you to remove your TV’s back panel. If your TV is under warranty, the optimal option would be to contact Samsung support since removing the back panel voids the warranty. If you’ve got nothing to lose, then don’t wait any longer and start unfastening those screws.
Dust is a common factor that prevents electronic gadgets from working correctly. There’s a chance that your T-CON board’s pins might have obstructed contact with the connectors due to the accumulated debris. After you’ve removed the panel, clean off everything you see. Use compressed air to get a hold of those areas which are difficult to reach.
.
Make sure to clean the ribbon cables. These ribbon cables are responsible for displaying the video on your screen. Dust and debris may get in the way of these cables, denying them a proper connection. There’s also a chance that somehow the ribbons got out of place.
You will need to take them out, wipe them gently to clean off any dust, and then set them back in correctly. This will clean off any obstructions and allow them to work properly.
Fix 5: Contact Samsung Support
If you’ve exhausted all of the options above and the vertical lines don’t seem to leave you alone, I would recommend contacting Samsung Support. A Samsung support technician will be able to diagnose the issue and guide you with better options as to whether it is optimal to spend more bucks fixing it or getting yourself a new TV.
