75" Samsung 7 Series 4K Smart TV - HAS DEFECT!

I have a Samsung 75" UN75TU7000FXZA that I absolutely love. So about three weeks ago I turned it on and there was a small line on the right side of the screen. I called Samsung help and they told me the TV would be $300 to repair. I had guests that week so I went out and bought the EXACT SAME TV so I wouldn't have to listen to my in-laws complain about not being able to watch the news. I don't know what do to with it now. I want to repair it, but then I have no place for it. I put it in the box of the TV I just bought so it's safe for now, but it takes up a TON of room in the basement. If I can get some money back, I'll eat the loss. I've got the accessories. If someone has an understanding of this stuff, they will get a great TV for cheap. You could even use it as is if you wanted.
