Samsung 70 TU 7100 TV Stopped Working Right After Warranty Expired

My Samsung 70 TU 7100 model TV has just gone out of warranty, and the LED light is blinking. Occasionally, there is a sound, but the TV does not turn on. I trusted the Samsung brand when purchasing this product, but now I deeply regret it. It is unacceptable that a product from such a reputable company fails so soon after the warranty expires. I want this issue resolved as soon as possible. The TV is 70 inches, making it difficult to transport. I will never use a Samsung product again. This is the first time one of my electronic devices has broken down, and it had to be Samsung. We paid so much money for this TV, and was it only meant to last 2.5 years?
