I just got a Rotel RSX 1055 receiver and am trying to get the thing set up. I did manage to get the on screen menu to come up once and even tried to select a few things but it stopped responding almost immediately. I know everything is hooked up OK because I do see the on screen menu when I power the unit on. The remote appears to be working (I can select mute on the remote and unit and on screen display reflect this). However pressing the OSD menu button has no effect and the same goes for up.down left/right buttons when the menu appears after power on. Any suggestions?
