Proceed PDT problem

I posted it at Audio Asylum. And got advise from kind Busybusy, not exact one though. I consider to ship my PDT to a dealer. Days ago, my Proceed PDP processor made a clicking sound with front panel 'emphasis' light blingking, and with sampling frequency display trembling, blingking llike 96 (it supposed to be 44kHz). Horrible noise purged to the speakers. The PDT transport likely produced bad signals. The PDT-PDP were connected by Madrigal HPC cable. What had happened with my cd player system? Any possible fix before letting it go to the dealer for the money? Really appreciate for your advise..
