Somehow I missed the common ground comment in the previous posts :) That was exactly the issue. Thanks!

FIXED: Use common ground.

I had this same exact issue and tried a number of things... using the ground wire as suggested was indeed the fix. Also to note, the capacitor and resistor are highly suggested as my matrix got insanely hot prior to the addition of those.
