@ahhk could be the speaker relay that does the clicking. We would need to see more from your receiver. Post some good pictures of the boards etc. so we can see what you see. Of course, check for obviously damaged components (charred, lost,etc.,) Since it only happens with SPDIF I would check the audio decoder IC first. IT is located on the X08-3060-10 (J70-1459-32) board.
