Just bought LBT-A190 system (very old).
Have managed to jam both casette doors.
Each time I put in a casette and closed door - it jammed instantly.
Managed to open doors by remiving covers and straining the locking mechanism - nothing broken (yet).
That happened to my old stereo too. I would advise you to contact Support via this form so they can advise you about repair possibilities.
