I purchased the 75" Class QN900A Series Neo QLED 8K UHD Smart Tizen TV and it delivered on 12/20/2021. On 9/10/2022 I turned the tv on and it had a big black square in the middle and there was no picture available. I called Samsung and they sent someone out the next week who said it needed to be repaired. Now more than a week later the parts are still on backorder but they will not replace the TV. My entire house is full of Samsung (refrigerator, dishwasher, washer, dryer, gas range, microwave, dishwasher, oven and 4 other tvs). Less than 9 months and now I will have a refurbished tv if this one is ever actually repaired. This kind of service tells me that Samsung needs to stick to cell phones. I guess they will let me wait another 3 months until the warranty runs out so that they don't have to do anything to fix it. Sony has much better customer service.
