I had my Onkyo receiver repaired to correct the LFE problem. Since that time, my receiver will not switch from digital back to analog properly. For example, I move from channels with analog sound to those that have a digital signal it switches properly. However, when I change back to the analog channels the receiver does not switch back and there is no sound. Does anyone have a solution? The Onkyo service center refuses to acknowledge there is a problem, though clearly it exists and was working properly before I had them fix the LFE problem.
