Help troubleshooting Pioneer SX-737 issue
I recently got a Pioneer SX-737, it appears to be in fine working order: powers on, all lights work (tho phono bulb isn't lit). . . However, when all components & speakers are hooked up, not getting any output sound. . . Have something in phono, aux, & tape 1, so it's not a single channel issue. When on AM/FM, there is *no* signal strength indicated.
Speakers are in working order, were just fine with my previous Onkyo tuner. Only issue on the surface with the piece is that the "function" knob is missing, but it can be turned between functions with no problem.
I don't know much about these, have DL'ed the service manual to try & troubleshoot on my own, but any thoughts on where to begin or look at are appreciated.
