Hi, I have a Marantz SR5007 and stock remote that came with it is the RC017SR. The receiver was responding to the RC until a few days back when I last used it. But, today I tried to use the receiver but it simply would not respond to my remote control. I've tried all the tests including the IR transmission through camera which shows the RC is fine. Changing from Main Zone to Zone 2 and back on the remote but nothing seems to make my receiver respond to the remote. I've looked at the panel and there's no external cables connecting the external RC ports or anything. I even did a factory reset on the receiver as well but my RC still wont work with the receiver. Now, since i cant use the remote my receiver is pretty much useless until I can set it up and it's really frustrating. Anything I may have missed? Please let me know what I can do!
