Sold broken tv on purpose.
||Posted . Owned for 1 week when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Better off buying from someone on the street. A random person has more morals and integrity than the employees at Best Buy. They hide behind a corporate logo to act immoral. Best Buy purposely sold me an open box tv in excellent like new condition that they no was not in working order. Obvious return when opened. The previous customer had put an envelope sticker on the back of tv with purchase date of July 2024 written on it. . I bought this tv in April 2025. I bought TV on Best Buy’s website. Drive an hour an half after borrowing a friends truck an hour and a half home to pick up a product that the staff new full well was broken. They didn’t care. Horrible ppl. They knew what they were doing. It’s no longer their problem after they sell it to me. Took a week and a half to return for full refund. Way to waste so many ppls time and money so you can save a couple dollars yourselves. Best Buy is a bankrupt company that finally needs to go away.

Delivery and installation of new 77" TV
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.my delivery was perfect and within the four hour window! I am hoping the installation goes the same way.
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!!!

No 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.
