Has anyone had an issue with the HTR-5890 where there is no output from any channel, including the pre-outs and the headphone outputs, except the subwoofer output? The unit powers on fine and all the video switching is fine, but the only sound comes from the subwoofer out jack. I was reviewing the service manual and it looks like the input selector IC-502 and IC 503 control the audio switching, it seems that they are not passing the audio. Any help would be appreciated.

Borrow a scope.
Maybe no 3.3 volt line to the DSP? I'm not sure if that line is monitored by the protect circuit.

**A service manual will be far more helpful with these horrors.
