No Sound from Radio
There has been no recent work on the RX.
The radio tunes and seeks on both AM and FM, and the CD player indicates it is playing.
The audio controls (bass, treble, balance, fade) do not change values when trying to adjust. They stay a the original factory settings.
There is absolutely no sound (hum, noise, etc) coming from the speakers.
I have not tried to disconnect the battery.
Does the sound system have a separate amp and fuse?
Thanks for your help.
