Had the same issue and the TV was only 18 mo. old (out of warranty). Went through tech svc. who could only have me reset the TV-issue still there! Got the info for their service center for my area. Fortunately I reserarched them before calling...never seen an "F" rating with the BBB! Made the decision to take it to a local repair shop with a good reputation who replaced the LED strip ($300). Said they had never seen LEDs burn out like that (I saw the strip, appeared shorted out). TV was fine for 2 months and the same thing happened again! Looking at this forum, there are MANY people with the same issue across many models. Samsung has to realize by now that this is manufacturing/quality issue. Very frustrated...I'm done with this TV and will replace it with another brand.
