Lines on Samsung TV screen

Last modified : Sep 03. 2019

There are a few different ways you might see lines or missing pixels on the TV screen. To determine whether this is a software problem or a hardware issue, please follow the steps below:

1 Check whether the lines on the screen are moving or permanent.
2 If the lines sway, check the input source (HDMI 1, Video, PC, etc.) and connection to see if they are properly connected. Disconnect and re-connect the video cable/HDMI to check if the issue is resolved.
3 Pull up the Menu screen and check whether the issue persists.
4 Perform a Picture Test by selecting the following options from your remote control Menu > Support > Self Diagnosis > Picture Test and follow the prompts.
  • Press the Home button on your Samsung remote control to bring up the Smart Hub and then select Settings.

  • Scroll down the tabs on the left-hand side and select Support. Once you are on the Support menu, select Self Diagnosis.

  • On the Self Diagnosis page scroll down the page and select Picture Test. You will then see a pop-up box informing you that a test photo will be shown. Select OK to advance.

  • A test picture will now appear. If the issue is intermittent, or does not always show in the picture test, it is worth booking a technician to service the TV as it may still be a hardware fault..
