I just recently received the Neo 2.0 for Christmas and it was initially working fine, but now only the lights work and will not pass the video signal to the TV
I figured it out. Had to disconnect everything, reconnect the HDMI first until the TV recognized it, and then reconnect the LED strips. Doesn't make sense to me but it's working now!
Sorry, but it's designed like that, you have to connect the lights first, then the HDMI output, then the HDMI input, lastly, the power sources, as it evolves with algorithm and something like that
