    Philips 258B6QUEB/00 LCD monitor no power

    Hello all,i`v got dead monitor,board model 715G8068-M0F-000-005I.
    There is 19V and 5V present on board where external power supply is connected,Enable and Dim signal is no present.
    I measured voltages and resistance on coils present on the main board,pls. take a look.
    Front LED just blinks for a split of the second when PS is connected.

    Its probably the main IC under the heat sink that’s the problem.

      Hello,probably,resistance on coil leads to main ic is quite low.
      I don`t have working board to compare the values,maybe it is normal
