Samsung UE-50RU7440 4K Ultra HD 50" TV Screen Shaking and Flickering

"The Samsung brand 50q60t 50” 127 cm screen satellite receiver 4K Ultra HD Smart QLED model TV that I purchased on 08.10.2021 developed a panel malfunction 6 months after the warranty period ended. The TV does not turn on at all; it makes a sound for 2-3 seconds, but there is no picture, and it keeps turning on and off by itself. There is no issue with the electrical connection, and it has not been exposed to liquid or any physical impact. I reported the issue and waited for the Samsung service to come. The Samsung service stated that the panel was burnt, that this was not a user error, and that it was a manufacturing defect from Samsung. They said the panel needed to be replaced and that it would be at a cost since the warranty had expired 6 months ago. They said they could replace the panel for a fee of 17,950 TL and left. I bought the TV 2 years and 6 months ago for 6,000 TL. There is no guarantee that replacing the panel won't result in the same issue. Moreover, it was mentioned that panel burnouts are common in the 50q60t series. It is extremely alarming that a brand as reliable as Samsung would charge such a horrendous amount of 17,950 TL to replace the panel for a TV that broke down after 2 years and 6 months and is not under warranty. If I had known I would experience this situation, I would never have chosen a Samsung TV. I hope they will carry out the panel replacement free of charge. My expectation from Samsung is that, as a company that fits the brand's image and instills confidence, they should perform the replacement free of charge. Asking for 17,950 TL for an issue that is not a user error but a manufacturing defect in this Samsung TV series frankly leads to distrust in the brand and is disgraceful. I have been truly victimized. I urgently want my TV to be repaired free of charge."
