Default Circuit diagrams and service manual for Rotel RTC-850?

I've been sold a dud and wonder if anyone has the manuals/circuit diagrams for this that they would be willing to copy to me?

Unit powers on but will not select inputs. When holding the tuner selection button in continuously the display lights and it will tune but all else appears dead.

Any help appreciated.
