Hi, I had my whole house working fine until I moved all my equipement in the basement. Now the lights hooked up on my second power supply twinkle instead of displaying a solid color. So if its solid green then the lights twinkle green with some blue. It was too late to troubleshoot last night so do I need to concentrate on the data signal or is this more of a power issue? Just want a game plan so I can troubleshoot after work today. Maybe slow speed of the pixels?
