printer doesn't power up

After completing the installation of the kit I powered up the printer but nothing happened. When I push the button of the lcd screen I hear a beep but the screen is blank. Also the hotend fan doesn't spin.

Answer this question I have this problem too

Is this a good question?

I solved the problem. Normally in electronics the red side of a flat wire needs to be on the side of pin 0. However in de rumba mini it has to be on the side of pin 10. If you look close at the picture you can see it. I turned the cables, red away from pin zero and it came to life. Works like a charm now
