    No picture Samsung NP-R523 MB:MODEL: BREMEN-D REV:MP1.2

    Hello!

    Notebook model: Samsung NP-R523
    MB: MODEL: BREMEN-D REV:MP1.2

    When connected to 19VDC, the current is 15-20mA. When you press the button (RUN), the current is 1.4-1.5A. LED and FAN are working. All voltages on the MB are normal.
    There is no image. Connected matrix, external VGA monitor, external HDMI monitor.I have an MB scheme.

    Please, help me!
    What to check?

    Thanks all!

      I've done all this. The North Bridge (215-0752007) and the video chip (216-0774007) warmed up (for diagnostics). BIOS flashed. The situation has not changed.
