Samsung TV Panel Failure

My Samsung UE43RU7400U television, which I purchased towards the end of 2019, suffered a panel failure about four days ago. I am a working professional and only use the TV in the evenings for a few hours a day. Experiencing a panel failure after such a relatively short and light period of use has seriously shaken my confidence in a brand I have trusted for years. Although the TV was bought in 2019, I no longer have the sales receipt due to the time that has passed. Considering my limited and careful usage, I believe this panel failure is due to a product-related fault rather than user error. I live in Istanbul, Turkey, and I have not yet contacted Samsung or any authorized service regarding this issue. I kindly request that the panel of my television be replaced free of charge, or at the very least, that the necessary repair be carried out without any cost to me, so that I can continue using the product without further problems.
