    I ordered a tv over two weeks ago. I took a day off work to be here for delivery and Best Buy canceled on me the same in the same time frame thay the tv was supposed to be delivered. I rescheduled for the next available Saturday, received a delivery time window the day of between 3:00 and 7:00 p.m. Best Buy just called 10 minutes ago at 4:45 p.m. to once again tell me that they couldn't deliver the tv today after I made plans out my day to be here once again. I have family coming from out of town later this evening to visit and now I have no tv. I'm not halpy about this at all. I will not recommend anyone to use Best Buy delivery for anything.

    I bought this TV on November 9th, 2024. It stopped working on November 10th, 2025... one day after the factory warranty expired. Evidently, this model has a known power supply issue that can cause the TV panel to stop working. Samsung is aware of this issue, but hasn't issued a recall. Samsung customer service would not help whatsoever. The customer service agent stayed on her script for over an hour and continued to tell me her manager was busy and wasn't available to speak to me. It's been a terrible experience. I've bought Samsung TV's for over 2 decades and have never had this level of difficulty with their product or customer service. They have lost a 25 year loyal customer. I would recommend buying a different tv and a different brand.. or you may end up having a 77" paper weight like me.
