One of my Denon 3806 receivers now has non-functional speaker leads for the surround and rear channels. The preouts work fine when I use an outboard amp, but I don't get any response from the rear or side channel speaker connectors when I try to use them. I also no longer hear the relay click when I switch the rear channel amp from "surround back" to Zone 2, which is how I had been using it (Zone 2 is my patio). I tried resetting the receiver's microprocessor, but to no avail. I initially thought I had a short on my outdoor speaker cable, but they tested out fine with my DVM. I cracked open the case last night, and all the fuses look fine, so I am probably going to take it to the local Denon service center. My suspicion is something in the power supply for the rear/side channel amps (they apparently use the same power supply) or the relay that switches the rear channel amps to other uses (in the "power amp assign" menu). Have any other 3806 owners had this problem? I want to make sure there is no obvious problem I can fix myself before I hand it over to the repair folks. TIA
