We own the Onkyo Home Receiver model no. TX-SR604. We have no complaints with the receiver except for the fact that we get an error message when we try to run the Audyssey: “ambient noise is too high”. We turned off every thing in the house including the fish tank pump, ref. A/C.....etc., in order to stop any noise. But we keep getting the same error message. We exchanged the receiver for another TX-SR604 but we get the same error message. All of the electrical breakers were turned off in the house except for the extension cord that we ran for the new Receiver. But we get the same error message.
After doing a lot of research on the internet, forums etc. we noticed that others are having the same issues. Please let us know how we can resolve this problem.
