MAHO MH400E trouble shooting

After replacing the electrolytics capacitors in the Indramat and in the Phillips PSU, it is time to start trouble shooting. When I power up the machine, the monitor receives power, and the Phillips controller receives power. The Phillips should boot, and the display should come up, but currently I have nothing but snow on the monitor. If I hit the hydraulic start button, the cerntral oiling system activiates correctly, switching off again 16 seconds after it gets pressure. The hydraulic pump is currrently not reacting.
