Anyone work on one of these? Thanks, Dani.


Doesn't look like a valid model number. Could it be

RX-V795?

Those of us who have had the (mis)fortune of having to work on surround
receivers these past few years have mostly learned to work around the
obstacles.

You can rig a double-ended AC cord (use ONLY polarized ends, and make sure
they match end-to-end).

Plug the receiver's own AC cord into one of it's switched outlets.
Plug your double-ended cord into the other switched outlet. This will bypass
the relay. If everything pretty much works normally, the relay problem is
confirmed.

Remember: The AC cord polarity must match or there will be MAJOR sparks,
since the AC line would be shorted if they were reversed. For this reason,
only an experienced tech really should attempt this.
