Anyone at Samsung Official
There is a massive, known problem with ethe 77" S90D: you manufactured a big batch of 77" S90D/S90DD (Costco version) TVs in late 2024 and early 2025. Their power supplies catch on fire, short out, and simply die TV turned on or off. These machines need to be recalled.
PLEASE PUSH MY WARRANTY CLAIM. It lit on fire internally, then this short caused my sinewave UPS protecting the TV to violently jet out smoke and fire and explosions from within it AFTER the TV burned itself up internally. I have an extensive case ongoing with Samsung support fully documented via audio and writing, no techs are available here, nobody is available to haul it--I'm on an island; please simply refund me like you do with every other customer in my situation. It's that easy.
The issue is extremely well documented with literally thousands of other Samsung customers suffering failed power supplies in their S90D OLED TVs from days to months from purchase date. You shipped faulty power supplies in them and they short out, trip the breakers of the circuits of the homes that they're plugged into, and then die without warning. YOU HAVE SINCE RELEASED AN UPDATED POWER SUPPLY. Absolutely no intervention on the owner's part is required for your TVs to smoke out and die without cause with the original PSUs in use. THIS DEVICE NEEDS TO BE RECALLED.
NOW, DO I NEED TO TAKE SAMSUNG TO COURT IN ORDER TO GET YOU TO HONOR THE WARRANTY ON MY NEARLY NEW S90DD? How about some customer service instead of having them email me one sentence every day informing me that she is waiting for a response from her manager, or asking me for photos that I sent in to the first CSRs i spoke with at Samsung nearly THREE WEEKS AGO? REALLY? What else was plugged in? REALLY? YOU BUILT A BAD BATCH.
Every conversation has been recorded by your systems and by me. They make for a really interesting story about fraudulent business practices perpetrated by your company--first selling a known, faulty product that is potentially deadly, then dragging your customers through the mud when your TVs fails spectacularly simply whispering magic smoke on them. What happened to the Samsung Name? You used to make nice appliances and backed them up. Now this utter mess.
MAKE IT END! Solve the problem, I implore you to do the correct thing here instead of having them waste more of my time, every day, for more than a week now after I've been transferred between four other "departments" back in mid September of 2025.
If you want the TV back, fly some workers out to the Big Island of Hawaii. Otherwise, send me my refund, in full, and stop perpetrating what is shaping up to be a very clear case of sales fraud. Thank you for taking this seriously and resolving this problem, then taking your product off of the market before it harms someone.
Sincerely,
Cmiller

Me Too. The power supply in mine quit the other night. It tripped the circuit breaker overnight while turned off. 77" OLED model QN77S90DDAAFXZA. I submitted a repair request. Waiting for a response from the repair company. Case 4183237804
Under warranty. Got the TV the end of Jan. 2025. It was in use until April, then off all summer until Nov. 2025. It's a winter home, so the TV had maybe 3 months of use.
I'm wondering if they corrected the power supply issue so it doesn't happen again. I'm seeing posts saying this is a common problem with this TV. Perhaps a bad batch of power supplies.

Wow, same thing happened to me.
Here's the thing. I bought it during Black Friday time end of Nov 2024.
It was delivered mid Dec 2024. I installed it and turned it on in my new house in Jan 2025.
It died EXACTLY one year from then. Jan 2026.
I didn't think I was going to be affected but here I am commenting about the same issue. Im out of warranty but I feel like they need to honor this. @samsungofficial It's such a known widespread issue. It's all over all the websites.
Also I'll add, mine is a 83 inch model of the S90D. Im so upset.

Same thing happened to my 77s93d. Worked fine for 6 months then tripped out the electric circuit whilst on standby. Samsung are awful to deal with. I have been dealing with their UK president via email, who refuses to accept this model TV has known psu faults. It's a disgrace that they continued to sell it and should of been recalled. My TV has been repaired but I no longer want it. The guy who collected it to be repaired actually admitted this model is often repaired as the power supply fails.

Mine failed too! Samsung 77 OLED. No power to TV. Purchased at Costco in December 2024. Preference is for a replacement as it wasn't custom installed until July 2025. Under warrantee. I think I already know the answer to this, but but who pays for uninstalling and reinstalling the TV since its custom mounted & installed with other components? What a pain!
