Hi Outlier - My Cortese/BiDat combo did this from time to time after I had disconnected the DC power cord to moved/reposition the Supratek. Carefully disconnecting and then reattaching the DC power cord on the Supratek seemed to correct the problem. I always found it strange that the Supratek "lit up" and appeared to be working even though the power cord wasn't in correctly.
Also... Sometimes the BiDats just quit working (temporarily). Perhaps this happens as a result of a power surge when its power cord is unplugged and then reconnected without using the rear power switch to turn off the unit prior to disconnecting/reconnecting power. In this state, I noticed my BiDat would sync but put out no sound for whatever reason. Flip the power switch on the back of the BiDat and let it rest for a while - then switch it back on. This might help. Once restarted, note the default input selection indicated on the front panel & be sure it matches the input you are using.
Other ideas... Hmmmm.... Well...The Supratek Syrah RCA inputs tend to be weak and break internally. I've never seen a pair of left/right female connectors break at the same time though. You might try a different input on the Syrah if you haven't already.
I hope this helps. Sometimes these things are mysterious. If I think of another potential problem, I'll post.
Lastly - be sure to have your BiDat upgraded & older useless mods corrected. The improvements are substantial.
