I have a relatively new

Question

I have a relatively new (less than 3 months old) Harmon Kardon Receiver HK3490. It turns on but immediately turns off. You can hear a clicking sound like a breaker is disengaging. The problem started when the Niles speaker selector autoformer MSA-10A that was connected to it went bad. The ac power supply on the Niles shorted out. I've tried the reset button on the receiver but this does not correct the problem. Any suggestions?
