Samsung not prime video friendly
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Don’t buy a Samsung TV if you’re planning on watching a lot of prime video movies or series. Takes forever load buffers all the time eventually freezes up with an error message. If you don’t watch prime video then it’s an excellent TV great picture and sound

Posted .Michael,
Thank you for sharing your experience with the Prime Video app. If your app is freezing, not loading, or crashing, you can try cold booting your TV by holding down the power button on your remote for 5+ sec until the TV turns off and on again, deleting and downloading the apps again, and completing full reset of Smart Hub to correct the issue.
Please also make sure your TV is running the latest firmware version. Go to: Settings > Support > Software Update.

Dead in less than 2 months
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Bought at the end of October and lasted until the first week of December. Called Samsung and they are sending out a repair company 5 days from now, and if it has to be replaced we have to wait even longer! How much do you need to spend for good customer service and a fast replacement?!

Disappointed
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Purchased Dec. 1. Delivery was Dec. 19 ,2024. Quit working Jan. 13. Wish I had sent it back. Best Buy should not have sold a tv with a known problem. I dropped the ball on my research . Jan . 27 2025 is my scheduleed repair day if the parts come in by then.

Best Buy, The Best Place to Buy!
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Great customer service and understanding of what product i was inquiring about.

Unhappy
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.The TV worked for 3 days before the power supply fried. It tripped the surge suppressor I had it plugged into. It also cost me an additional $250 to have Best Buy come out and R&R this TV. They should have back charged Samsung.

Disappointed and Done RIP Samsung
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Bought this TV in December 2024, by August 2025, it's completely dead. It doesn't turn on, doesn’t respond at all, and even swapping the power cord didn’t help. Just lifeless. Meanwhile, my 2017 Samsung TV still works perfectly. What happened to your quality? This experience has completely changed my perception of the brand. I won't be buying Samsung again.

Donated to a Smash Room
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I’m sad to write this review. I purchased almost 14 months ago. Two months after purchase the motherboard went out. I had to wait 12 days for technician (not geek squad) but thankfully covered under manufacturer warranty. Now the same problem is happening. Warranty is expired. I decided to chuck this lemon and purchased a Sony.

I would recommend this to a friendStopped working in less than two months
||Posted . Owned for 2 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.TV didnt turn on one morning. Called Samsung tech support, they confirmed that it would require a technician to diagnose. Its been 3 weeks since they offered to replace it under the manufacture warranty and ive got the runaround. I didnt purchase the warranty from Best Buy, so i cant return it or exchange it. I had been wanting a good Samsung tv for a few years, but after this issue, im going back to LG or Vizio.
