    Yow Kristijan78, the information you requested is hard to obtain, never the less I have some clues for you to try….. Figure out the Vcc on pin # 6 of IC601 (1200AP40) this device should give you an average of
    The total Vcc on ZD601, the ZD601 may average from 12-45 volts or more. You should establish this before replacing this component.
    D604= Low end Diode
    R623= 4.7_E
    R116=?
    R611= 221_E
    R613= 1K_1/4 Watt
    ZD601= Zener Diode
