Best Buy 1-star review by Ebell5555 (title: "Stopped working after 77 days"). Bought Oct 10; on Dec 28 would not turn on. Best Buy Totaltech would not replace and deferred to Samsung; week-long wait for tech who claimed to have the part before diagnosing.

Best Buy 1-star review by ThomasH (title: "Fine for 2 months - AVOID Samsung TVs"). Within 2 months developed a massive red bar along the bottom half of the screen. Samsung outsourced repair then closed the ticket; third-party repair in Austin was poor.
