I have Samsung 82" 4k QLed tv just out of the 1 year warranty that has lines on it toward the bottom of tv going across and then a section going up in middle of tv as well. All inputs show the same thing, reset tv to factory default and same outcome. No Samsung service texts in my zip code? What do I do or can I do. The is is the 1st Samsung tv I have ever had an issue with? Please help?
