I purchases a s3400 htib from Amazon. It worked great for a week, then I had a constant light static in the front speakers. I diagnosed with Onkyo support and they informed me the receiver was bad. Amazon immediately sent out a new unit. That worked fine for a week. Now I have an even worse static issue coming from all speakers. I even disconnected all my inputs and the static remains. It appears to go away with the FM tuner. I even ran 14 gauge wire for added protection. Do I just have bad luck to receive two defective receivers in a month, or am I doing something wrong in the setup? I have the receiver plugged into the wall, so no power strip issue. I tried the factory reset (vcr/power button), but still have the static. Any assistance would be greatly appreciated.
the problem is onkyo doesn't have any official service center here and send it back might cost me a lot
