• Trouble shooting XP1000

    From Joukj@21:1/5 to All on Fri May 8 10:36:46 2020
    Hi

    One of my XP1000's had to be relocated. However I cannot power it up at
    the new location. When I push the power button I see the Fan in the top
    front run for 1 second and than the machine stops

    What could be the problem?
    or
    What can I do to trouble-shoot?

    Regards
    Jouk

    Even stranger.... I left the power cord in after the last try and when I
    came back after 2 hours, the machine had powered itself up.

    Output capacitors on power supply are bad. It's worth just shotgunning all
    of the electrolytics on the board. Since you are in Europe on 240V power,
    also suspect the two high voltage electrolytics on the primary side. They seldom fail in the US but frequently fail in Europe.

    I agree with Scott, powersupply is failing.
    If you shut it off again, it likely won't fire up at all.
    Backup your media right away.

    Sometimes machines overheat and switch off. :-|

    that's my plan.
    It is running now for several days.
