Only first LED turns on

    I've looked through the help hoping someone else has fixed this issue already but haven't seen it yet. When plugging in my Raspberry Pi and my Lights the signal seems to be going through, however only the first LED is turning on. My setup is as follows:
    - Raspberry Pi 3
    - Hyperiban
    - Aclorol WS2812B LED Strip Light 30 Pixels/M
    - 5v 10A power supply for the LEDs
    - MicroUSB power supply for the Raspberry Pi (included with the Pi)
    - HDMI to USB capture card


    I assumed this was an issue with a common ground, and when I spliced a micro USB into the adapter for the lights and ran it off the same power it worked, however that splice is pretty week (the cables are pretty small) and keeps falling out of the connector or the wires are breaking. To alleviate that I connected the LED's ground to a ground on the Pi and that also did not work. Worst case scenario I can work on the splicing and try to make that the permanent solution, but if I can avoid that I will.


    Thanks in advance

    Just an update:
    Decided in the meantime to try splicing the wires again. Did that, as long as I don't move it should have a short term connection. However, the problem persists. To add more context, I have the positive of the micro USB and the positive of the lights (not where the connector is attached, just the second red wire) spliced into a barrel connector. The same is done with the grounds. Then the GPIO 18 is connected to the green on the LEDs (through the connectors). Last, another GPIO is connected to the ground on the LEDs (through the connector). So now I'm not sure why this is happening, I figured splicing it would work as it had before.The one LED that is lighting up is reacting as it should, but it is the only one that is on.

    have you set up the LED Hardware section of Hyperion, inc the LED layout section?


    Ideally you should be sorting the poor connections out first and double check its wired correctly, If its bad it may or may not work but it may also damage things connected to them, bear in mind you have a 10amp power supply and a strip of LEDS that can consume a fair chunk of that at any given time for a period of time is your wire and connections up to the job of delivering the current it needs as that could be a whole load of additional problems once you get more leds lit making the quick fix a long drawn out nightmare.


    If in doubt ook in the showcase section and see how others done it :thumbup:

    Sounds to me like an led layout in hyperion issue. Make sure to set your starting point in the LED layout section. If I remember right I had similar issue. Check number of LED and start and end location too. I'm almost certain this is your prob...as mentioned before as well

    I do have the LED layout set up, I can post a screenshot later today. I have it set from the bottom left to the top down the right side, no bottom. If I look at the preview on hyperion everything looks accurate, I'm starting to think something may have touched with my connector and shorted it out. I'm going to try to use another strip of lights that I have to see if that's the issue. If so, I probably killed the strip

    So I found the issue, it's what I expected. The power supply pulled one of the positive wires out a bit and it touched the ground wire, killed the LED strip. I plugged in another strip, got the right results. Fortunately I found the issue, unfortunately I don't have enough to redo the TV so I need to buy some more. Thanks for the help everyone, and bright side I get to practice my skills

    Apologies for necroing your thread, Zachary, but I wanted to ask a follow-up question, which you might be able to answer since you found your issue.


    I've just installed my first ever Hyperion on my first ever Pi, and bought my first ever addressable LED strip (W2812B). I followed instructions (YT is wonderful) to the tee but the strip did absolutely nothing at all, no matter what I did in Hyperion (and I saw the live preview in Hyperion change colors as I changed the colors on the wheel in the app)

    HOWEVER, while everything was running, I accidentally disconnected the common ground from the Pi, and the first LED on the strip turned on, shining green. That's it. If I power everything off again, everything stays off, but if I pull the common ground again, the first LED turns on. I'm 100% certain that I didn't short any wires, merely disconnected the Pi's ground.

    Googling the issue brought me here, so I ask a stupid question:


    Could disconnecting the common ground fry the strip? And if so, are all 5 meters of it dead?
