Hello,
Maybe someone has an idea, where to look at.
I have a setup with Rasperry Pi 3, APA102C LED Strip with 121 LEDS and a 5V20A BTF Lighting Power Supply.
Also in the setup is a Video Grabber, a HDMI2AV converter and a HDMI Splitter. The latter 3 should be irrelevant though, since the problem only occurs when the Ambilight is off.
When Ambilight is on, everything works 100% and I am totally happy.
The problem: When the Ambilight is off, sometimes some LEDs (mostly around the first 20 LEDs, sometimes also some later LEDs, but always in the first 2 segments of the setup) turn on by their own. This happens more or less once in 30 - 60 minutes.
It seems they receive 1 data signal which makes the turn on in mostly blue and red colors, then nothing more happens. They are just on. I can fix it by switching processing via hyperion on and off again, then all LEDs are black again for the next time.
I checked the wiring, it looks okay (not perfect, I had not been soldering for 15 years before, but okay). So no shortages or stuff like that.
And as I said, the setup basically works all perfect except for some LEDs turning on on their own all 30 - 60 minutes.
Any ideas?
