Yamaha Rx-z9 Shut Off Upon Power Up.
My Yamaha RX-Z9 has begun to shut itself off immediately upon initial power up. I have had it connected to a Panamax power conditioner, so I don't believe a surge has reached it, especially since no other device has shown indication of being damaged. Any suggestions?

I also have a RX-Z9 and it was shutting off for no reason. It was driving me crazy because no one would want to fix such a complex beast. I found the solution and it works perfectly. The rear panel of the amp must have some grounding or connection to the internal boards and if you take a screwdriver and slightly loosen and then firmly re tighten all of the screws on the back panel ( turn power off of course) then this problem will be solved - too simple but it fixed my problem immediatly and has not happened since.
