    Hey guys,

    I have a little problem with my Hyperion Setup.
    I made this setup 2 times and it did run very well for the first 5-6 weeks. On both systems I got the same issue now.
    The LEDs starts to flicker in some weird ways. On the first setup they start to flicker on 5 LEDs in some random spaces and on the 2nd setup the whole stripe begins to flicker randomly.

    If I pull out the 2 datacables for Di and Ci the flickering stops immediatly and the LEDs stays at the last shown color.

    I tested the powersupply to be pluged in different outlets, nothing changed. I resoldered every soldering point, nothing changed. I reinstalled hyperion, nothing changed. What else can I do?

    Could it be, that there must be a resistor between any cable or any other electric component?

    Thank you all in advance.

    Hardware that is used:
    Raspberry Pi 4
    Libreelec => Flickering Kodi and HDMI to USB Grabber as well
    APA102 LEDs (60/m)

    SRY for my english :(
