My wife got a second hand Vagabond which worked fine for a while then she got the dreaded "Pop" and the machine was dead.
Being an engineer I decided to take it apart to see if I could fix it.(the trick to getting it apart is to remove 4 screws hidden under the "corner protectors" as well as the obvious ones behind the drop down flaps)
Once inside you will find a small printed circuit board with a little yellow gizmo which you will probably find is scorched (hence the pop) I was unable to identify what the gizmo was (thermistor or capacitor is favourite) So I soldered a link across it's 2 terminals and bingo, a working Vagabond.
Perhaps someone who knows more electronics may be able to identify this component and let us all know
