Pioneer DDJ SX1 weird problem with power!

Hello guys, i have one question about pioneer ddj sx. I have a strange problem and the problem is thats the controller simply power off while working in the club, and after that, I have to start the button again. The strange thing is that when the adapter (power supply) on the floor is close to the source of vibration and noise, this problem occurs. However, when I hold the adapter on a table where it is also a controller, that is, above the floor away from the vibrations, the controller works and not power off. Also, ive tested controller over night, i left them to play and in the morning everything works fine. Ive tested adapter too, by punching them and shaking, everything work fine.
So ive wonder if anyone had a similar problem and is the problem in the adapter or in the controller itself, power supply board or something? Best regards, Edvin
