Clavia Hissing and Clicking

Hi,

My clavia nl3 is having some problems lately.. after luanching this machine it starts to make clicking and hissing noises after about 1 minutes, it gets worse by minute..

Anyone an idea? Already checked my cables and stuff.. It really is the nl3 that is infected..

I really do not want to miss it for a week or two (or more !!) Anyone knows a shop near antwer which repairs fairly quickly or could give me a replacement..?
