i recently bought to a friend a traktor s4 mk3 and show me that one display only power up and stay in white, but doesn´t show the track wave and information, the other display works normally (he told me is a factory defect) is there any solution?
You can try swapping the displays to see if the one is actually defective. To do this, you'll have to disassemble the controller. Maybe you'll get lucky and the ribbon cable might be loose. However, you almost certainly won't be able to get a replacement display from NI. As already mentioned in other replacement parts threads.
Hello,
There is no such "factory defect" on new devices… It can happen of course, usually after years of use or if the device was malfunctioning since the beginning (but in this case, you simply return the device to NI and they send you a new one).
Your "friend" simply sold you a problematic device… and there is no solution for this…
