My husband and I purchased a 65" Samsung 4K Tv from Best Buy. The box wouldn't fit in the car so they sent us home without the box. Long story short they didn't give us the screws to mount the tv and it fell over weeks after we bought it. The sound still works but the picture is pure black. Best Buy won't replace it. Any suggestions on if it can be fixed? It's a $2,000 tv and we really don't want to buy another
