    Powersupply: EAX55176301/12

    Symptom: dead no 5v, both fuses ok.

    Check ZD501 (3.6 Zener) R501 (2.2ohm 0.5w resistor) IC500 (ICE3B0365J)

    usually zener, IC are shorted and resistor OL or very high.

    replace zener, resistor and IC500 (ICE3B0365J)



    Schematic attached.
    Here, found the same problem. However Zener looked ok ( I changed it anyway ).

    Replaced all components and it is running fine.
