Thin Horizontal Line of Pixels Near Bottom of Samsung TV

Hello, I purchased a Samsung tv, model # UN65NU6900FXZA a little over a year ago. Just after the manufacturers warranty expired I started experiencing a thin horizontal line of pixels near the bottom of my tv screen disappear. I’ve confirmed with Samsung this is a hardware issues. Looking for guidance on what component might need to be replaced. Thank you.

PS: hockey game on since it has a white background for contrast. Ball looking object in bottom left is a part of the game. Only issue is one line of pixels.
