Miniscan HPE 'dead' Anyone know what could be the problem?
Posted 24 July 2012 - 11:24 AM
Got a dead Miniscan HPE, that is, it won't light up, home, or activate the fans.
Looking at the circuitry, after the fuse holder is the safety switch and after the safety switch is the ignitor that divides power to the lamp itself and to the fans and transformers/electronics.
My guess is that the ignitor has gone, but could it be something else?
What's the normal moving light diagnostic in this situation?
Cheers for any help!

To start with you need to trace the mains voltage through from the input using a 240V multimeter and see where it is not getting to.

Check BOTH fuses in the IEC socket as the Miniscan has a fuse on both live and neutral (mine do, anyway). If its not the fuses, it will almost certainly be the switch. If it is, I've got a couple I've removed off a couple of mine when I converted them to LED. If you need one, let me know.

I'll meter between the fuse holder and safety switch but I'm thinking that it's another duff fuse holder again. Had this problem before with other Miniscan's. Must be wear and tear on the holder contacts inside I guess....
