I bought a new aux/cassette player for my sc400.it was working fine until one day music stopped working on the right side of the speaker...this happened to my previous cassette tape that is why I bought a new one and the one I just bought was a few days old... Is something wrong with my cassette reader? The right side still works when I play the radio..can anyone explain why it's not working? :/

 

Try flipping the cassette?
