I would recommend this to a friendNo good!
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.TV looks great only issue i have is day 2 of me owning it the speakers were no good. The sound coming out of the tv sounded muffled or distorted even at 100percent volume. Read online that this was a common issue with the tv. Reached out to Samsung and they got me in contact with a repair technician but even before I spoke with the repairman they called me saying they already had ordered parts and were waiting on them so they could service it! Must be a known issue if they ordered parts without actually speaking with me or even looking at the tv. Awaiting for the fix but still gets 1 star because it sounds like Samsung knew this $2000 dollar tv is faulty.

Dont buy. Common power failure
||Posted . Owned for 2 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Bought the S90D 77inch in store January 2025. Early March less than 60 days no power failure. Common problem with this TV. Look it up before buying this TV. Check Reddit, and the questions on Best Buy. Some owners have had three failures on one TV. DO NOT BUY. GET THE LG C4!

Buyer Beware
||Posted . Owned for 2 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.There is a known issue with the power supply, your TV will all of a sudden just not turn on. Best Buy‘s help during the first year unplug it for 30 seconds and then plug it back in. Did that work? Even though you purchased the geek squad protection plan.

Worse TV and experience
||Posted . Owned for 4 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Was excited about this TV as Samsung has been a pretty good brand of TV foe me. Thats where the good stops. After 4 months the power supply went bad (google it; known issue). The closest repair company from samsung is hours away so we had to wait a month to get it repaired. The repair took all of 5 minutes and we were back up and running. Fast forward two weeks and now screen just turns on and off every 10 seconds. Audio works just fine throughout, just the screen issue. Completely done with Samsung at this point and now having to fight them to just refund so we can get an LG OLED. To make things worse Best Buy wont help at all since its outside their short return window and we had forgotten to “upgrade” our Best Buy service plan level. Terrible experience and would recommend anyone stay as far away as you can from this TV.

Owner
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.This TV is a great for streaming but after 25 days my TV stopped working for manufacturing reason possibly lol
I would recommend this to a friendRUN DON'T WALK AWAY FROM THIS STORE!
||Posted . Owned for less than 1 week when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.We spent over $400 on a new TV and sound system. Scheduled install for Saturday, November 23, 2024. Everything went beautifully. Technicians left and we went back to Best Buy to make a purchase recommended by the technician only to return home roughly three (3) hours later and turn the TV on to find a huge 2 inch white dead spot running from top to bottom in the center of this brand new TV. Called Best Buy, scheduled another appointment for a replacement TV. Received appointment email stating between 730AM and 1130AM. Followed technician on the tracker which stated he would be at my house by 830 this morning. The technician "Alexis" exited the highway by my house proceeded to sit somewhere for 30 minutes, got back on the highway proceeded to go to some other appointment. Called to find out the issue only to be told I would be his next stop and that he would call me to confirm. No phone call and no Alexis. Called the 800 number three (3) times, talking to people not even in this country telling me he will be here, he will be here. I have spent almost 2 hours on hold with various agents. No one can connect you to a supervisor. It is now 11:55AM well past my appointment window and I still do not have a working TV!!!
