Q: Why won’t my new tv not turn on. Power outlets are all ok
A: 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.

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.

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

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.
