The screen is damaged at the center

Modern large screen televisions are rarely cost effective to repair when the LCD/OLED display is damaged. They cannot be repaired, so the only solution is to replace the panel. Unfortunately, most of the time replacement displays aren't even available, and even when they are the cost is usually more than what you would pay for an entire television.

So I'm sorry to say there's really not much you can do with that TV. Best case would be for you to disassemble it and sell the boards and power supply inside; there is generally a market for those kind of parts so you can recoup a small amount of the cost of the television.
