I am out of my mind pissed off at Onkyo right now. I bought the 706 about a month ago. When I hooked it up sound plays just fine from all of my 5.1 speakers while watching TV or listening to music. When I use the Level Calibration feature the test noise plays fine from the front right, center, and front left channels. When it plays through surround right, sound plays through BOTH left and right surround speaker. So I try the Audyssey automatic setup. Same problem and it tells me it can not detect surround left speaker. I call Onkyo they say sorry you need to return it.
I get a 2nd 706 receiver. I hook it up today and first go to play the Level Calibration noise to see if I get the same problem. To my pleasant surprise sound comes from each of the speakers. Now I hook up the Audyssey mic and run the automatic setup. The sound pulses start playing from my front left speaker then I get an error message saying it can't detect my front left speaker!?! Well why the hell not! The sound plays just fine from it. Ok, so maybe it is the Audyssey mic? So I try the mic from the first receiver and same problem.
That's 2 receivers with similar problems. This is where Onkyo customer support is going to come to the rescue, right? NOT! I call them and go through the same basic troubleshooting stuff and, big surprise, come to the conclusion that it doesn't work and needs to be returned - AGAIN. I tell him that I have to pay return shipping on this and would be stupid to try a 3rd time. I told him that Onkyo should replace it and pay for shipping. He says you need to speak to our customer relations department to work that out and he transfers me to customer relations. Some guy answers the phone, "hello, parts". I ask for customer relations and he says that the customer relations guy is out today. Incredulously, I ask him, "do you mean Onkyo only has one customer relations person" to which he replies, "YES". Are you kidding me?? Onkyo has one customer relations person in the whole freakin country? Are you kidding!!!!
So I must calm myself and wait until tomorrow for Don Phillips, the one and only customer relations person for Onkyo to tell me I am out of luck and they won't replace it for me.
Thank you 706 owners thread for allowing me to vent. I will let you know what Mr. Phillips has to say.
