Relay is clicking on and off
I suspect my Pioneer VSX-D608 has a power supply issue. When I turn it on from standby, the screen turns on and there’s sound from the speakers. But after a few seconds, or after I turn the volume up, I hear the main relay from the power board click and after that the receiver restarts.
I wonder how to troubleshoot this issue - what is the main reason for the relay switching? is the system shorted somewhere or is it a bad component?
