Hello, I am new to Audio Karma and I have learned much for reading the discussions on the forums from time to time that I thought it was time to finally join. I'm having an Issue with my Marantz 2238b receiver. It works and produces sound but all the controls such as volume, bass, treble, and mids do not work. They're stuck at the settings that I previously had. Turning any of the dials makes no difference. Wondering if anyone has some insight or had the same probably?
