Hi Rich Plotner,

Receivers usually use relays to provide speaker protection in the case of a fault on the output of a channel (also used to prevent the speakers from catching fire if due to a fault there was excessive current flow to the speaker). it sounds like one or more are operating.

Here is a link to the service manual for a Onkyo TX-V940. It has all the information, e.g. circuit diagrams etc, to help you to find the problem.
