    Lenovo ideapad s400 display

    Hello community this is my first post asking for help. the issue is as follows, I have a lenovo ideapad s400 notebook which broke the display. It was replaced by another simile display but the white light of the inverter flickers. investigating I read that the backlight of the inverter works at 600hz and measuring at the output it gives me 33hz does anyone know about this problem? If you need more information do not hesitate to ask me.

    I saw this video that has the same inconvenience but I do not really know what it is that bridges or because resistance changes. change the resistance changes the output frequency?regards

      Also, when I check the voltage on the...

      PL 1600 = 5valw present
      pl 1100 = 3 vlalw present
      pl 100 = 0.221 v without battery and when battery connected 7.8 volt
