It very well may be to simply unplug from the power source for 1-2 minutes and then plug it in again. I have to do this with my CJ preamp at times. One thing to understand is that many modern pieces have a computer(s) which go astray at times. Like your phone or computer, it needs a restart
It isn't dead., it is turned off and like I said, the owner's manual tells you how to remedy it. If you don't have a manual, you can download from the McIntosh home page.
