Proceed Amp 5 Repair

Good afternoon everyone.  My Proceed Amp 5 started acting up yesterday.  I purchased the unit used last year, and it had been great.  Yesterday when I tried to fire up the system, after pressing the Stand By button, it seemed to "shut down" and the power light began to blink.  

Has anyone dealt with issues like this?  It seems very difficult to find any "authorized" repair.  I am located in Michigan, but will ship to repair if needed.  

Any advice would be appreciated.  

Thanks,

Jim
