Someone already got this problem ? Seem that one of my 5 cube doesnt receive power as the others... My 4 cubes are at 240 W + and cube 2 is always at 6-7 watts... ? Ive tried all possible combinaisons and i noticed that's really the problem of this cube and not wires. Thank you
I would say take the ribbon cords out from the controller board one by one until you figure out what cord belongs to that cube.
Then i would say unplug the rest of the cubes the same way and only leave that one cube plugged in. Then i would say turn it on and mine and see if its still doing it.
If it is, then try the power cord from a known working cube and if its still doing it.
Then try a ribbon cord from a known working cube and if its still doing it.
Try a different slot for the ribbon cord on the controller board. And if its still doing it then email knc for RMA after you have reflashed the micro sd card with firmware from scratch and the problem still exists.
If it at some point in the trial it starts working then you know it has to do with that part. My initial guess would be a power issue.
