My Samsung Tv has about 4 or 5 faint lines run across the screen right in the middle. Why are they there and how can I get rid of them? Help!
@tffnyvq Horizontal lines are almost exclusively caused by a bad panel (Failed gate drivers) whereas vertical lines can be a TAB error as well as bad wiring. We would have to see what those lines look like to give you a more definite answer. Post some pictures of what your screen shows with your question. Adding images to an existing question
Most likely it’s the problem either with ribbon cable that connects display to a motherboard, or display itself. That if those lines are always here, no matter what is the source.
