    Psu voltages test...
    There is also a way to test the voltage from the psu without connected it to the main board, and so unballast by bridging the 5vS (5v Switch) and Con psu female pins.
    However keep in mind that the 34v from it could be lower, something between the 25v/29v which is a normal behavior when it's unballast but when it's normally connected to the main board (without the 5vS to Con bridge) it should be the 34v.
    The other voltage must be exactly.
    Be carefully, when you bridge the Psu if it's active, do not touch any parts on the Hot Zone, there is more than 300v (Dc) on the Hot Zone side.

    Vu Duo Psu/Pcb ohms measurements of the power connector...
    Different situations to determine where the problem might be.

    Good luck.
