Why Is My Samsung TV Showing Horizontal Lines On Screen?

Samsung TV lines are a common problem that can be frustrating to deal with.

There are several reasons why your Samsung TV shows these horizontal lines on the screen when you turn it on. The most common issue is related to the display of the TV, but there may also be an issue with your cable box or HDMI cables.

Below are a few reasons why a Samsung TV will have lines.

1. Damage on Display Panel:

If you see horizontal lines on your TV screen, it’s probably because the display panel or screen is damaged. However, this isn’t always the case. There are other factors that can cause these lines to appear. In order to determine if your TV has a problem with its panel or screen, it needs to be thoroughly checked by an expert before anything else is done.

2. Issue With Input Cables:

Is your TV screen displaying horizontal lines? If so, this is not a problem with the TV itself. The issue might be that the HDMI cable on your Smart Hub or Smart TV is loose or unplugged. Here are four different ways to fix the problem:

  • Unplug and plug in the HDMI cable again.
  • If it’s loose, change out the cable for one of higher quality.
  • Disconnect other devices from the power source to free up more power for your TV or use an extension cord if necessary.
  • Try moving closer to your Wi-Fi router.

3. Image Resolution Issue:

Have you ever seen horizontal lines on your TV? It’s probably because the image resolution is different from the display size. The TV can’t load properly. One quick way to fix this is to change the image resolution of your TV.

4. Out-of-date Firmware:

When you get a new TV, it is important to update the firmware. Old versions can cause problems with your TV’s graphics display and may not be able to process higher resolution pictures. Plus, there are always new features that come out periodically that you will miss out on if you don’t update your firmware!
