my 10 yr old supertuner 3,which i love comes on and plays but audio output to rca jacks has ceased to exist .checked rcajacks,amps turn on etc.problem is inside head unit.any help appreciated

 

The RCA Jacks you are talking about that do not work, are they for the sub output or line out? What Model receiver do you have? I have the DEH-P3900MP SuperTunerIII.
