Can anyone help me? I've taken apart a konica copier machine and i salvaged among other things this lamp with its inverter.
the problem is the inverter has 3 pins on the input. by following the traces to the capacitor i've found which one is the + and the ground but i cant figure out whats the 3rd (middle) pin and the lamp dosen't start! it dosent draw any current either.
i gave it 15V on the + and middle pin, i even put the middle pin to ground, but nothing happens.
i didnt try giving it the full 24V as all of my other scanner light inverters start with less than their full voltage.
here are some pics:
please help
i tried bypassing the fuse, dosent work.
The ic is a 10393 comparator so i'm guessing there should be some voltage on that pin to maybe set the intensity of the light.
thanks in advance
