Samsung 77" class S90D OLED TV
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I recently purchased the Samsung S90D OLED TV, and I couldn’t be happier with it. The picture quality is absolutely stunning—deep blacks, vibrant colors, and incredibly sharp detail that really make movies and shows come to life. Motion is smooth, and the HDR performance adds an extra layer of realism, especially in darker scenes. The design is sleek and modern, and it looks fantastic in my living room. The smart TV features are responsive and easy to navigate, with plenty of apps and streaming options available right out of the box. Sound quality is surprisingly good for built-in speakers, though it pairs nicely with a soundbar for an even more immersive experience. Overall, I really like my new S90D. It delivers on everything I was hoping for in an OLED TV and feels like a major upgrade. Highly recommended.

Amazing Picture Quality & Performance!
||Posted . Owned for 11 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.This TV is absolutely stunning! The OLED display delivers rich colors, incredible contrast, and deep blacks that make movies and shows feel truly cinematic. The 4K resolution is crystal clear, and motion is buttery smooth whether I’m watching sports, gaming, or streaming. The Smart Tizen platform is fast, user-friendly, and loaded with all the apps I need. Setup was simple and the design is sleek, modern, and looks great in my living room. At 77 inches, the screen size is perfect for an immersive experience, and it easily becomes the centerpiece of the room. Samsung really knocked it out of the park with the S90D series. Highly recommend this TV to anyone looking for top-tier quality—it’s worth every penny

Amazing tv
||Posted . Owned for 10 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Purchased this tv after doing a bunch of research. I had a 4 year old roku purchased second hand that lost its backlight. Another website was running a sale and i was able to price match for a decent deal. This tv looks amazing. Every person thats come over notices it right away. I mainly purchased for ps5 gaming, however the operating system is pretty decent and i find myself using the built in streaming services and "live tv" options often. This specific tv comes with a qd oled and while it doesnt look much different to my eye, apparently reviewer websites say this is better than woled. I cant believe i waited so long to purchase an oled. The non oled to oled upgrade is actually insane. Easily the largest upgrade when it comes to graphics(way better than say upgrading your ps5 to a pro or getting a better graphics card.) At the same time, im glad i purchased when i did cause this tv is perfect.

Stunning OLED
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Deep blacks with a rich color gamut makes this a powerhouse OLED TV for everything, especially gaming. Peak brightness makes the colors pop even more. Take all your 4k media to the next level with 4, 2.1 HDMI ports. Can support gaming up to 144hz which is a big plus. 77 inches looks like a movie theater in my living room.

Power Supply Board (PSB) Issue
||Posted . Owned for 6 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.The picture quality, profile, and sound in this tv is great. Unfortunately there is a common issue with this model, S90D 77”, where the PSB fails suddenly. This seems to happen within the first few months of usage typically. Mine lasted about 6 months until one day my tv shut off and the curcuit breaker for the room flipped. Thankfully samsung has a 12 month manufacturer warranty thay covered the cost of the replacement part (which is now redesigned not to fail) and the labor for their techs to come out. I wont give a lower review simply because they were able to come out so quickly and were in and out. But if i were to purchase a new TV, I would not go with this specific model. My other Samsungs have lasted me very well (in fact, i still have one from almost 20 years ago going strong), so I wouldnt steer away from the brand… yet.

Stunning Picture, Bright Even in Daylight
||Posted . Owned for 1 week when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I’m extremely impressed with the Samsung S90D OLED. The picture quality is absolutely stunning with deep blacks, vivid colors, and razor-sharp detail. Even during the day with a lot of sunlight coming through my windows, the screen stays bright and clear. The built-in sound is pretty good, much better than most TVs I’ve owned, but I would still recommend adding a soundbar to really get the most out of your movie nights. One thing to note: the TV is a bit on the heavier side, so if you’re planning to mount it make sure you have a solid mount and someone to help lift it. Overall, this is a fantastic OLED TV that performs great in both dark and bright rooms. Highly recommend!

Power board supply failure
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.TV has incredible picture but after about a year of use my TV will no longer turn on due to power board failure. Very disappointing considering how much I've spent on the tv, and after a year of use I need to spend $400 to continue using it. What's going to break after that. I've had $100 TVs last longer then this.

Elegant Lemon-Scented Brick
||Posted . Owned for 2 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Elegant. Thin. Stunning. These were some of the adjectives I used to describe my Samsung 77" S90D Series OLED TV. The picture quality is exquisite. It hangs in my brightly lit living room and is able to display deep blacks and vibrant color during the day. Sports and movies are equally beautifully rendered. So, why only 2 stars? Because the TV died after 71 days! I was out of town for a few days, came home and went to turn on the TV. No response. I figured maybe the remote battery was dead, so I charged it. No dice. Then I checked the power cable, power outlet, unplugged, replugged. No luck. Then I commenced googling and YouTubing. Found the power button on the actual TV. Tried different sequences of power resets. Nope. Apparently, Samsung knows that this is a problem. I have scheduled onsite service, and when I called to confirm the date, I was told that the tech has already ordered the parts. If you know that these TVs are lemons, why still sell them? For now, just a few days before the Super Bowl, I have an expensive, elegant, lemon scented brick on my wall. Should have just bought the Sony Bravia.

This question and answer was generated by AI based on customer and product data.Q: QuestionWhy won’t my new tv not turn on. Power outlets are all ok
Asked by Anonymous.
- A:Answer I had the same issue. There appears to be an early failure problem with the power supply on the S90D 77-inch TVs. Failure typically occurs after 1 or 2 months use. TV won't turn on and the red standby light does not come on. Repair is pretty simple - replace power supply. But no guarantee that power supply won't fail as well. I chose to return my TV and go with a different model. Too bad because the picture was excellent while the TV worked.
