Two-Year-Old Samsung UE50TU8000UXTK TV Screen Failed

On October 14, 2020, I bought a television, and two days later, I noticed a spot on the screen. The service team arrived and informed me that the LED had exploded inside and that it would be replaced with a new TV. I requested that it be returned, but they insisted on bringing a new device. They delivered a new UE50TU8000UXTK model TV on November 4, 2020, which we used without issue for two years. However, on 10.12.2022, just before the warranty expired, the TV turned off with no image or sound. When I called the service, they asked me to send a video, which I did, and they reported me an 8.500 Turkish Lira fee. When I contacted Samsung customer service, they asked me to have the service team look again and give me a new price. When the service team arrived, they realized lines on the screen, possibly requiring a complete screen replacement at a cost of 8,900 Turkish Lira plus VAT. They clearly want me to foot the bill. When I looked up the model online, I noticed lots of complaints about the same problem. I believe they sent me a faulty product on purpose, and I am unhappy with Samsung's customer service. I am unwilling to pay for the repair and have lots of questions. Did Samsung send me a defective product on purpose? Is it true that Samsung products have a two-year lifespan? Why did the TV break down so soon after the warranty expired? I regret buying a Samsung television and advise others not to do the same.
