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.

A Cinematic Revolution in My Bedroom
Setting up the Samsung S90D OLED 77” was a breeze—everything from unboxing to installation was seamless, but nothing could have prepared me for the experience that followed. As soon as I powered on the screen and queued up Napoleon Dynamite, I was utterly transported. The sheer size of the display, paired with its breathtaking OLED clarity, made me feel as though I had stepped into an IMAX theater, right in my own home. Watching the talent show scene, it was as if I was sitting front row—every detail, every subtle nuance of Napoleon’s awkward dance moves felt larger than life. The realism of the colors and the depth of the picture were nothing short of mesmerizing. I wasn’t just watching a movie; I was living it. The way the screen rendered every vibrant, quirky moment of the film felt so immersive that I nearly reached out to high-five Napoleon as he celebrated his iconic performance. This TV is not just a display—it’s a gateway to experiences so rich, so vivid, that they transcend the boundaries of your living room. Whether you’re a cinephile or just looking to elevate your home entertainment, the Samsung S90D OLED 77” will transform your viewing experience into something truly cinematic, unforgettable, and simply jaw-dropping.

Amazing brightness, detail, and response time.
The tv is amazing. Extremely bright has very little to no issues with glare. The game mode is amazing allowing you to put a permanent dot in the center of the screen for better accuracy. It’s fast and responsive. My only complaint with the tv is the remote doesn’t have a simple input/source button. It also has a really cool split screen mode on the tv allowing you to enjoy separate content at the same time.

Samsung 77” OLED TV died in first two weeks -
This 77” Samsung OLED television stopped working suddenly and the screen went black and dead within two weeks of use. I purchased this television as a Christmas present for my children and was completely disappointed to levels incomprehensible- when it suddenly died while they were watching it. Afterwards I read reviews on the Samsung website and found out this exact television has numerous complaints reporting this exact problem - it simply dies after short usage. Will not ever purchase a Samsung ever again. I have to wait over 10 days for a Best Buy refund to my account before I can shop for a new - different brand television and I am angry and disgusted with both the store and the manufacturer. Good riddance to an awful television and I will definitely read the reviews BEFORE I make another purchase.
