What is causing these horizontal lines
I have a Samsung UE40D5520 Led TV
ANSWERS:
@mynameisstu horizontal lines are most often caused by a bad panel (failed GATE drivers or failed TAB). Not much a DIY'er can repair on that. Post some images of what your screen looks like so we can see what you see.
Hi.
MY PROBLEM DESCRIPTION: a faint (watermark quality) multi-colored ‘banner’ across entire screen of my 65” SAMSUNG TV, approx 6” above bottom of screen, and 6” high, made up of multiple lines of what appeared as possibly highly blurred text or interference signals of some sort. this problem suddenly appeared following a storm related power outage.
