Its so sad to have come up with some funny issues on an expensive set like this. Cdj2000 displays "Please wait, communication error" when turned on, would have to wait for bout 10mins for it to start working properly, tried to manage that. Came up with another one, Jog mode keep switching from Vinyl to Cdj (like some seconds Insterval. very annoying) can't scratch. then the "skip forward button" was active, track skipping by itself. And whenever I press the range button the tempo button responds to it... So that's watsup' so what can be done to resolve all these. any software firmware voodoo? or should I just do away with the set. cos these is kinda awkward and very embarrassing I will so much appreciate any helpful suggestion, than the one that says "PLEASE CONTACT YOUR NEAREST AUTHORISED REPAIR CENTER" cause we do not have any here. thank you and God bless... In addition. No liquid or beer or water has ever poured or splashed on it, tried as much to be careful with that, always in the Dj booth in a flight-case.
