Samsung TV horizontal lines on the screen may appear due to some hardware malfunctioning inside the TV. If you see vertical and horizontal lines on Samsung TV, that means your TV’s panel is damaged. The good news is that, in most cases, you can fix Samsung TV horizontal lines without calling a technician.
In this article, we will show you quick fixes for Samsung TV horizontal lines on screen issues. We will also provide some tips on how to prevent this problem from happening again in the future.
Check the HDMI cable
Check the HDMI cable to see if it is securely connected to the port on your TV. If it is, unplug it and plug it back in to make sure that the connection is tight.
Check for loose cables
1. Check all the cables connected to your Samsung TV. Make sure that each cable is securely inserted into its respective port.
2. If you find any loose cables, tighten them and see if the lines on your screen disappear.
3. If the problem persists, try disconnecting and then reconnecting all the cables one by one to see if that makes a difference.
4. You could also try disconnecting and then reconnecting the power cord to see if that helps reset the TV and get rid of the lines on the screen.
Check the TV’s refresh rate
One common reason for seeing horizontal lines on a Samsung TV is because of the refresh rate. The refresh rate is how often the image on the screen is refreshed. If the refresh rate is too low, you will see horizontal lines on the screen. To fix this, you need to increase the refresh rate.
To do this, go to the Settings menu and then scroll down to System. From there, select General. Scroll down to External Device Manager and select it. Select Turn On if it isn’t already turned on. Then, go back to System and select Input/Output Settings. Select HDMI UHD Color and set it to On.
Check the aspect ratio
The first thing you need to do is check the aspect ratio of your TV. The aspect ratio is the ratio of the width to the height of your TV screen. If the aspect ratio is not correct, it can cause horizontal lines on your screen.
To check the aspect ratio, go to menu, then to picture settings. Under picture settings, look for something called “aspect ratio” or “screen size.” If the aspect ratio is not set to 16:9, that could be causing the horizontal lines on your screen.
Check the resolution
If you’re seeing Samsung TV horizontal lines on your screen, it’s likely because of a setting that’s not configured correctly. The first thing you should check is the resolution of your TV. Many Samsung TV models have a “Game” mode that is designed for use with video game consoles. This mode disables some of the image processing features that can cause input lag, which is the delay between when you press a button on your controller and when you see the action on screen. If you’re playing a game on your Samsung TV and seeing horizontal lines, make sure that Game mode is turned off.
Check the overscan
Overscan is a feature on your TV that zooms in too much on the image, making the picture look cropped. This can sometimes cause horizontal lines to appear on the screen. To fix this, go into your TV’s settings and turn off overscan.
Perform a factory reset
One last resort you can try is to factory reset your Samsung TV. Usually, this will fix any software glitches that may be causing your TV to display horizontal lines. To reset your TV:
1. Unplug your TV from its power source.
2. Press and hold the “Menu” button on your TV’s remote control.
3. While holding the “Menu” button, plug your TV back into its power source.
4. Continue holding the “Menu” button until the screen displays the message “Self Diagnosis Mode.”
5. Use the arrow buttons on your remote to select “Factory Reset.”
6. Press the “Enter” button on your remote.
7. Enter your TV’s password, if prompted.
8. Use the arrow buttons on your remote to select “OK.”
Check for updates
Updating your software is always a good first step because it might be a quick fix. Check your TV’s menu for a System Update or Firmware Update option and follow the instructions to install any available updates.
Contact customer support
If you have a warranty or extended warranty, your best bet is to contact customer support for your TV. In most cases, they will be able to help you troubleshoot the issue and determine if it’s something that can be fixed at home or if it will need to be sent in for repair.
