Just wondering if anyone had any ideas on how to get the bass treble fader etc working again. I can push in the button and cycle through all the options, but when I spin it to change the bass or treble etc it doesnt do anything. I did remove negative from battery for a few minutes to reset but same problem. Everything elses works on the radio.

It might be a solder joint break on the potentiometer itself. Ive opened my radio up many times. It is time consuming, but very easy.
