My Samsung 50TU8000 TV Panel Failure Can't Be Fixed

In January 2021, I bought a Samsung 50TU8000 model TV from the Teknosa store in Gaziantep Forum Shopping Center, it was one of the most expensive TVs in the store at that time. They said it was guaranteed for 2 years, if you wish, we can extend the warranty for 1 more year by paying 400 TL more, and we bought the product with a total of 3 years warranty. In April 2023, my Samsung Brand TV started to turn on and off by itself, I called Teknosa, I told Teknosa, they said the warranty was over, they said the product had insurance, they said you call Gulf Insurance, I called Gulf Insurance, they sent a technical service, they took the TV and left, then 5 days later a message came, your TV cannot be repaired. We gave you a Teknosa gift voucher worth 5200. I called the technical service and talked to them and they said that Samsung 50tu8000 models always have panel failure and this is a chronic problem. So the world brand Samsung cannot produce a TV that lasts more than 2 years? We will buy a TV every 2 years for the money we earn. Now I ask you, from which brand can we buy a 50 inc TV for 5200 liras? In this article, I am complaining about Teknosa for calling insurance a guarantee, Gulf Insurance for giving 5000 lira for a 13 thousand TV, and Samsung. For producing a TV that does not last 2 years. I will go till the end.
