NU7100 issue - horizontal lines on screen Hey did anyone else have a problem similar to mine? I have a 58” Samsung NU7100… and about 7 months after purchase…a thin single horizontal line appeared in the screen… It disappeared a few days later before a technician was able to come in and diagnose the tv….then the day after my warranty was finished, 3 lines reappeared… Samsung does not want to cover the repair since it’s over warranty now. Anyone else have this issue and what was your solution if you resolved it without a technician? Thanks!
