I just inherited a beomaster 5500... I cannot figure out for the life of me what I am doing wrong. The tuner lights up, but the modes are not changing. The master remote works, it switches through modes but tuner is not changing and no sound is coming out. (Stuck in Tape, and I do not even have a tape to see if any sound is coming out from that) Could it be in some kind of locked mode?
Thank you! Cybele
