Hello. I picked up a "barely used" Denon AVR 2160,but I get the "blinking red light and shut down" that seems to be a fairly common thing(?). I have read and watched and then I read some more about doing a "hard" or factory reset,the thing is that I can't find anything helpful for that exact model ( E 400, 889, etc...) Can anyone PLEASE explain to me EXACTLY how to do a factory reset?, any other tips, tricks, or even a cheap place to get it fixed in Denver,Co.? Thank you.
