    I had undertaken literally hundreds of major electrical projects over the last 40 years before I got my broken Durst. In fact I got a soldering iron for Christmas when I was seven years old. Gary Mulder is also quite well versed in electronics.
    If you have 'no clue' with electricity it might be best to find someone that can look at if for you.

    Mains/line voltage electricity is not something to treat lightly. If you do not have a clue with electrical stuff, as ic-racer said, I highly recommend that you find someone else who does. Dealing with mains/line voltage is potentially fatal if you make a mistake. I have seen some "repairs" that were done so poorly that someone could easily be seriously injured or a fire started.

    Re: durst power supply EST 1000N

    hello guys,
    I just got a Durst 1840 and power supply EST 1000N , it was ok some time ago but there is a problem now

    When I put it on "on" and start a timer to expose paper, the "shutter" on the head opens and closes non stop...
    I think it could be a relay flickering...
    -I tried several timers, same result
    -tried different current socket in the building, no change
    -electronic on the enlarger itself seems pretty simple so it could be on the power supply.
    -the fan starts but seems to have some difficulties and acts as a stepping motor 'kind of"
    -light is ok
    excuse me if I'm not very precise, I'm french, I hope you understand the problem

    any clue/advice?

    Update:
    It was a micro switch on the back of the board which didn't go back to its initial state!!
    Thank you!!
