Lines on Samsung TV screen

Last modified : Apr 04. 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.
Smart TV: There are horizontal/vertical lines on the TV screen

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.

5 If the lines stay on the screen no matter what input source you use, please call 1300 362 603 (in Australia) to speak to our Samsung Care experts.
