Some LEDs sometimes turn on "by their own"

  • 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?

  • Hello Elhyperiono :) ,


    i have the same issue but only 2 or 3 around the termination.
    i'm suspecting that the led are little bit dammaged when i weld connectors.


    when you stop the service hyperion and you press the heating element on the led strip close to the led you should see a color light right ?

  • Ok forget what i said..; the led color changing only when the all led are working and pressing the black component.
    other thing i noticed is when i'm connecting some other element to the multisocket one or two led are switching on... so i'm suspecting some electrical disturbance.
