For days ago i got this Esselte moviebox from 1987, it seems to be in a okay condition, and there is some functions there working, but no play option, i notice that on the front was a label with information about the machine will not play when the rent period is over, its a kind of secure .
I open the moviebox up and toke a look inside, i notice there is a battery box and four "DN837" Hall elements at rear, so the question is, does anybody knows something about to break that secure so i can use it forward?
There is some pictures where those two cables are connected,
in the comments of this video someone from Sweden suggests (I think) putting a magnet over the box (my Swedish isn't very good though, only very basic if yours is better you might want to double check what they are writing)
(NB: be careful not to magnetise the video heads if you try that!).
Thanks for your answer, i allready tried to move a magnet over those four hall elements and it works for a short period, but now it´s locked i think, but never mind, the machine is in real bad condition can i see now, so i think its only for spareparts for my two other similar machines.
