    May be useful if you have a problem with this type 5L0565 psu.

    I've made a voltage overview from the safe side of the power supply unit, but not from the hot zone because the voltages of the hot zone are comparable to the 25X10 PSU.
    Nevertheless most of the problems arises on this side, and the measurements could also give a impression if it is a problem on the hot side.

    For convenience, I also give most data sheets related to this type psu.
    These are the,
    IC400 FP5001
    U1 MP1484EN
    IC500 FP5001
    U2 MP1484EN
    Q200-Q001-Q501-Q401 Y1

    Q3 5L0565R
    Q400 FQP 27P06
    Q500 FQP 27P06
    D300-D301 MBRF10100CT
    ICI VIPer22A 4AYL5L

    Be careful with the measurements, do not make any short circuit during measurement.
    And avoid the high voltage area.
    Good luck!.
