[QUOTE="laphroaig, post: 1179737, member: 158089"] Thanks for your reply! These are both powered by the same 5V port, I checked both grounds and they should be fine This turned out to be true. CLK and Data were soldered wrong way - fixed this, but nothing changes. Still some of the leds light up. Actually when I first started testing these, the GND and 5V were mixed up too, and it caused the wires turn warm/hot after a short testing so I checked the solderings and fixed those but didn't realize to check the other two :) I checked the direction again and it's going in the flow of the arrows on the strip. It behaved the same way even when using the wrong direction (which I did with first tries with the strip) I installed using Hyperion's setup instructions for OSMC, it should be up to date and from master branch. ------ Should all the lights stay lit up when given just 5V and GND, or does it need CLK and DATA too? I'm trying to figure out if the led strip itself is broken or is the arduino not getting or passing the serial data to LED strip correctly.
