    Lenovo 6622-hb1

    Hi,

    Have a problem with the power supply ...

    It's a 715g2538-4 power supply

    The monitor came with a blown fuse,wich I replaced together with the 0.47UF capacitor,and the NTC ...

    But the fuse blows again ...

    Any advice where to look

    Now I have seen that R914 - 0,22ohm 2W is blown , and the C938 has no legs

      Replaced R914,C938 and Q901 (P10NK70ZFDP with P10NK80ZFP) but the fuse blows again

      Rechecked the diode D901,D900
      Rechecked the capacitor C905,C903

      All other seems OK

      Any advice,

      thx
