    Mori Seiki SL-1 Lathe Screen Not Turning On

    Dear all,

    When I turn on with the green button, the machine turns on half of it (some pcb turn on and some doesnt)
    The Spindle drive does not turns ON. The screen doesnt turns ON.
    I have meassured the 24VDC input in the screen and it is OK (voltaje is present).

    I would like some orientation on where or what to search in the screen pcb.
    It is a CRT fanuc model A61L-0001-0072.
    I am not sure if there must be another input voltage comming from the signal cable.

    I would also apreciate if you can give me an schematic (Electrical) of the screen or the complete machine.

    This is a machine with FANUC SYSTEM 6T

    Thank you for your help.

    Martin, Have you been able to repair the problem yet? I had a similar problem a few years ago, and I am going to look for my records on it. Al I remember so far is that there was a board behind the keyboard which has a DC - DC regulator, I believe that it had 24VDC input and 5VDC output, and it was defective.
