Yamaha DM 2000 mixer, looking for repare service

I own Yamaha DM2000 V2 Digital Mixer and Im looking for good repare service. Actualy the console is working perfectly but all faders have to be repared or probably replaced because they get stuck and they don't react properly. Also Top Board/panel has to be replace as old one is already worn and scratched. Any idea Who can do it? Kind regards, Millo
