Hi all
I got everything up and running on my Rpi3 running OpenElec. I tested everything prior to cutting the LED strips and placing on my TV. Everything worked fine.
I cut a 5M strip of APA102 into 4 sections. 42 LEDs top/bottom and 24 on each side. I am driving them with a 5V 12A PSU.
Whatever I tried I could not get the lights to come back on, even with the same Hyperion config. I also noticed that the Rpi3 would start rebooting randomly, or screen would flicker.
So here's something weird. I had a small section of strip left over that had 10 LEDs left on it. I connected that between the PSU/Rpi3 and the first LED on the first strip on the TV, and it works! All LEDs light up and I have no more reboot issues.
Wiring looks sound and I've checked it 100 times both at LED end and the connectors on the Rpi3.
Any idea what could be causing this?
