    any tips on repairing a switching power supply that has an output that's
  2. Mainly capacitors. Could be a zener diode or something in the feedback, like
    a TL431 voltage reference or a problem in a voltage divider. Lots of other
    possibilities, though, and the more complicated the supply, obviously the
    more potential suspects.

  3. Make sure you have a load on the main (regulated) output!
