found a tx-v940 at goodwill. same problem - no power to speakers. Did randomly come on at times, but when powered off then on again, there’s nothing at the speakers again. Also a series of clicking noises, like some component is powering on/off. Wondering if it’s a bad relay switch….?
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. http://diagramas.diagramasde.com/audio/O…
