I have a Pixlite16 driving WS2811 pixel strips - 16 strings of 75 pixels. On one of the string outputs I have a single pixel showing blue when white is being displayed. I have changed the string to another one that is displaying the correct colour and it too displays the same (blue when it should be white). The controller is a V3.6 and has V1.4.14 firmware which I have reflashed. It did this last year as well but I thought it was a bad string and didn't worry about it at the time. I am using Vixen 3.4u1 but as mentioned it also did it with an earlier version. When I check the strip with either Advatek Assistant and the Pixlite 16 or another controller all pixels on all strips display correctly however in sequences a single pixel won't play the game. Any ideas?
