Audio Systems: stereo, pioneer vsx, preamp section

Question
                              I accidentally selected a live input on my Pioneer VSX-21 receiver when the volume was very
                              high. By the time I turned the receiver off and back on again I had lost all audio output on all my
                              inputs. Did I blow out something? Is there any reset button on this box?  

Answer
sorry to say that the preamp section is probably damaged. only other possibility, if youre lucky, unplug power from unit for bout an hour and see if set resets. otherwise, ask around for a reliable repair shop...if they want alot of money up front, be wary........G.......
