Im not a technician so please bear with me.
I've acquired a Hitachi 8190E that needed tape belts. The tuner was working before I started work.
With new belts and a clean the tape deck is now fully functional but the tuner doesn't work unless a tape button is pressed as well!
I've cleaned the usual suspects like the play/rec switches and mode switch and checked for loose connections etc. but now I'm out of ideas.
Thoughts would be very much appreciated.
