I installed 4 years ago hyperionNG (first it was hyperion) on my Raspberry 3 with APA102 LED stripes and a USB grabber. My setup causes more and more trouble with single segments of flashing LEDs.
I checked the wiring and it should be okay as it's never moved in any way. The flashing LEDs occur while using my USB grabber or on a static scene. So I don't think my usb grabber and/or splitter causes thi.
The raspberry itself (GPIOs or processor) shouldn't be the problem as well, as the hyperion software does not show the flashing leds in the live view.
What's also interesting, the problem becomes much more worse when the color RED is displayed. And it's most of the time blue leds that are flashing. And the problem occurs everywhere on each LED. Most times a segment of about 10 led's is affected.
Do you have any idea about this? Does my power supply can cause these issues? Or is it the wiring itself? (There are a few soldering points). Or are my APA102 LED stripes just over the time? (I had to replace/delete ~4 LED pieces within the time because of malfunctioning colors.
I don't want to start troubleshooting by replacing various random parts as the system is very "integrated" into my shelf, wiring and television. It's a mess to dissable everything so i would be very glad just to replace the broken part.
Any ideas? Help is very appreciated.
