Thanks for the video, because I see something different. You shouldn't get anything lighting up when the faders are down, if I'm not mistaken.
There might be another sort of issue going on. If I may suggest something, please try to swap your TT cables around, and see if the problem stays on the same channel or if it moved to the other one. Double check the grounding too, because this seems unusual. Also maybe related to being a new purchase, but let's not get that far at this point.
