text: I installed the lighting on the back of my 70" TV. I quickly found that the USB port is always hot (powered) on this TV, so I need to use the included remote to manually turn the light strips on and off. I found the remote to be non-functional. I tried a new battery which did not work. After trying everything I could think of, I contacted the seller. I was told they would gladly send me a replacement unit, which they did. I got a replacement unit and everything works. I am very happy with the lighting and how it enhances our movie-watching experience.
