Sigh !! 4 days slogging over the alignment of this SA-PM148 vcd changer and no results yet. I cant find any service info pertaining to mechanism alignment. I did get it going once, then i packed it and next morning it started making those awful gear cracking sounds and everything went out of mesh. Anyone know how to align these gears and trays. The unit has this "disk check mode in which all 5 cd trays protrude out if activated. Help Please :( Jango!
