[QUOTE="Rick164, post: 1128518, member: 17766"] Have seen this happen before with the WS2801 leds but that was an power issue as it would spike and turn random leds blue, could you post your Hyperion config and arduino sketch? Just in case there's some config error there but doubt it, is there an resistor connected to the data line? Also make sure none of the exposed wires are too close to each other as that could result in interference and that your ground wires are connected properly, best to post in the Hyperion topic btw so we can keep it in one place :) Also as another test you could try with the Hyperion android app is to go from full white to off (brightness slider) and see if it happens with that as well.
