Problem with my CD73, no sound from the analogue out, is ok from the digital out connected to my AVR300. Connected my Ipod to the CD analogue in on my AVR300 to make sure it was the CD73. It take the fault is on the DAC side of things????? Had a look inside and noticed white deposit lying around X401 (not sure what this is) on the PCB. Any ideas what the fault could be?
