Please help me. I have been trying to fix issue for 3 months now. My ws2811s will light up to the 15th bulb, after that i get nothing. I changed strands, still the same thing. I went to sandevice configuration board, ran test, all lights work. I checked my channel configuration on sequence software (SUPERSTAR) and everything looks right. I updated my configuration board, hoping it would help. Any help would be soooo appreciated. Thank you
