    DELL 2405FPW - Dead - Fixed

    I hope this may help somebody. I had a 2405FPW that was in a bad way.

    Usual failure mode: Open circuit C605. Cascade failure ensues.

    It is working now. There was some parts that were definitely bad, and some parts that tested OK. There were some parts that I just did not feel comfortable proceeding without replacing them.

    Note: the attached circuit diagram is for a 2407. That said, the similarities between the 2405 and 2407 PSUs are very handy. Check my comments in the PDF to see what I found.

    Good luck, these PSUs generally will work again with a little love.
