I have a ambilight system built with a Raspberry Pi 3+ and a WS2801 with 114 LED's. Everything works fine, except that one LED on the side of my TV is always green. When I display another color it changes to it, but it always keeps a little green touch. When I display a black screen or it does not get any other input it changes back to green.
Does anyone have an idea why that happens and how I can fix this?
