Samsung TV horizontal blue lines on screen: Causes and solutions
There is likely an input or display problem if you see lines on your Samsung smart TV. Horizontal lines on the screen could also result from a software fault with your Samsung TV. Also, it leads to display problems like stacked images and blurriness. Here are some easy troubleshooting tips.
Samsung TV software issues
The software of your TV can develop problems over time, or an upgrade may be needed to resolve one. Additionally, older smart TV software may have trouble rendering the visual elements of streaming services. Any of these factors can cause horizontal streaks. Therefore, the most recent Samsung TV software version is essential for bug fixes and enhanced functionality.
Update your Samsung TV software
When your Samsung TV needs to be updated, you may have picture quality issues. The lines-on-screen problem on Samsung TVs may be resolved by installing a specific update that contains bug fixes. Here are the steps you should take to upgrade your Samsung TV:
- On your Samsung TV, launch the Settings menu, then select “Support.”
- Choose to Update Now under Software Update. The newest software updates can now be found and installed on your smart TV.
- Wait until the installation is complete. After that, let your Samsung TV restart and see if that fixes the problem.
Factory reset the Samsung TV
You can reset your Samsung TV to factory settings as a last resort. Resetting your smart TV involves erasing all user data, including accounts, passwords, and any other personalized adjustments that may have been made. In addition, this will remove any user profiles, apps, and linked devices you may have created. So have a backup before resetting it.
To return a Samsung Smart TV to its factory settings:
- To access the settings, press the menu or home button on your remote.
- After that, you will have the general and privacy options, where you will get an option to reset. Tap Reset.
- The default Samsung PIN is 0000. Then, in the confirmation window, click Reset once again.
Power cycle your TV
If you have a Samsung TV and see horizontal lines on the screen, try a full power cycle as soon as possible. It’s possible that faulty connections between the boards, processors, and connectors are to blame for the lines. Alternatively, the T-con board could malfunction due to a fluctuating voltage.
Additionally, the TV’s software may be experiencing a momentary hiccup, which could explain the lines. A full power cycle of the Samsung TV should fix all these issues. To accomplish this:
- Manually Turn off the TV by disconnecting it from the wall
- Wait for 30 seconds.
- Reconnect the TV.
- Start watching something on the TV.
Samsung TV input source problem
If your Samsung TV is having input source problems, there are a few things you can try to fix the issue.
Unplug and plug in all cable connections to the TV
Most horizontal lines on the screen are caused by a loose input cord that causes movement or flicker. A permanent horizontal line usually indicates physical damage to the unit, and this modification is unlikely to help.
However, it is still worth a shot when it is a brand-new TV. If your TV is linked to input devices like cable/satellite box, Blu-ray player, etc. All you need to do is double-check the cables.
Remove the TV, One Connect Hub, and other input devices from their respective wires.
As you reconnect each cable, check to ensure the plug is snug in its port.TVs with various inputs allow you to quickly and easily switch between them.
If the lines are only visible on one or a small number of inputs, try retightening those cables or swapping them out for new HDMI cables. The One Connect cable may also need to be tightened or replaced if the lines can be seen on all inputs and are moving or flickering. Make sure the new One Connect cable is compatible with your Samsung TV by comparing the model number. If the lines remain constant on all inputs, it isn’t the wires.
Check on faulty cable connections and replace any
Ensure that the cable connecting the external device to your TV is in good working order. Check the cables for any signs of dirt or damage while disconnected so you can make any necessary repairs or replacements.
In addition to that, check to see that every cable is securely plugged into its respective port. You must take the same precautions with the cords attached to your cable box and other devices linked to your TV.
Ensure AV cable connections to the TV are correct
- Verify that the TV’s input setting is set to the input to which the A/V device is attached. If it isn’t, try switching it.
- Ensure the TV and the audio-visual device are turned on before continuing.
- You can check if a picture is displayed on the TV screen by first pressing the INPUT button on the TV remote control, then switching the input to the location where the A/V device is connected.
- Verify that the cable is attached tightly to the TV and the audio-visual equipment, and make sure that it is not dangling loose.
- Check to see if the A/V device, such as a Blu-ray disc player, is connected to the input selected in the audio system’s input setting.
HDMI connection problems
If you’re having trouble connecting your HDMI device to your TV, try a few things.
Replace the faulty HDMI cable
Your HDMI cable may need to be fixed or updated to function correctly. First, change the HDMI cable you’re using to see if that makes a difference in your problem.
Fix the HDMI port if not working
You should switch the HDMI ports on your TV if you’ve only connected a single device, such as a cable or satellite receiver. If you have tried connecting to a different HDMI port, but the screen continues to display blue lines, you will need to reset both the TV and the video source by unplugging both. Then plug everything back in after one minute, including the HDMI cords.
