My 5.1 Kenwood with Infinity 5.1 speakers started having almost no sound from the front speakers. Center and rear are normal. Eventually (three weeks later) the receiver would not turn on. I bought a new Onkyo, and it has the same weak sound from the front two speakers. I can see nothing wrong, wires are fine. I am lost, but a little scared to test as I do not want to fry my new receiver.
