I have an issue with my Rainbow cube, One LED will not light up it’s green colour, and when I switch LEDs on and off with CubeXControl, it turns on multiple LEDs at the same time for some locations.
I know the LED is good, as it will light up all colours if I power it directly. I am assuming I have messed up the jumpers, or have missed a solder joint somewhere.
Is there a circuit schematic somewhere? I think I need one to track the problem with my multimeter.
Or any other suggestions?
