    Hello,

    i'm using Hyperion on my Raspberry Pi with OSMC and controll it with the Hyperion Addon for KODI on my Nvidia Shield. The RPi is powered over the USB of the TV.
    Now the Problem is, that if i turn off me TV the RPi also shutting down and the LEDs on my TV are off but after some time 1-2 LEDs turning on and shining in some color. Shurely that only hapens if the LEDs are power suplied, if i disconect the powersuply everything switches off.

    Thanks in advance.

    this is normal, caused by electromagnetic interferences.

    the only for me known solution is to "send to all leds black" if hyperion isnt used... @penfold42 is there a technicaly way?

    Try adding a 1k pull-down resistor between data in and ground

    Mine flicker even when on and running if I turn the fluorescent lights on down stairs.

    Long feed wires make good antennae
