      i bought on e-bay a defect ipad (no backlight) and i see the apple logo on / off but not possible to put in recovery mode by i-tunes error 4005
      The PCB looks fine , and i think i made a short by measuring , because before PPVV_main was stable on 3,75 V

        i think that PPVCC_MAIN has to be stable before going further ?
