RPi + Other Software APA102 setup flickering after a month

    Hello all,

    I did my setup following these instructions: https://hyperion-project.org/threads/raspberry-pi-3-mediacenter-hyperion-ambilight-no-soldering.77/

    I'm using raspbian stretch as my OS.

    Everything worked pretty well for about a month, now all of my LEDs after the first 15 or so (estimating, I'm not at home at the moment) flicker/go crazy. Also, using hypercon, when I set the LEDs to black (off) on the color wheel, the working LEDs turn off but the remaining go 100% white.

    I'm thinking that maybe an LED blew, but i'm not sure how to test. I've messed with smoothing settings, lowered the baud rate, and turned off grabber/other features to try to isolate on the software side. I've also removed/reinstalled hyperion.

    Some of the other threads mention using level shifters, but they weren't mentioned in the tutorial - or is that just for another type of setup?

    Please let me know what pictures/information to provide.
