Hi,

I brought home my third Onkyo HT-S590 receiver yesterday, hoping that the third time would be a charm. Below is a description of the problem I'm having and the troubleshooting I've done. If anyone else has this problem and/or has found a solution, please let me know:

Problem Summary: The audio works fine with RCA analog connections but stops working after awhile when either optical or coax digital connections are used.

Setup Notes:

· The Onkyo receiver is being used only for audio. Video is via S-Video from each video source to the TV.

· The coax digital cables are six feet long.

· There is ample circulation of air to cool the receiver.

Problem:

· With any digital connection from any source, the sound will eventually stop working.

· The problem usually occurs after the receiver has warmed up.

· The problem occurs on both speaker sets A and B.

· Turning the receiver off and on restores the sound for a few seconds.

· Happens in both stereo and surrond sound modes.

Notations: YES = the problem occurs. NO = no problem.
