    FANUC MAIN PROCESSOR NOT BOOT.

    Hi!
    I switched on the machine (HITACHI-SEIKI HG400III, 1997) today and saw this messaged in display.
    "GRAPHIC IS READY. WAITING SERIAL BUS IS READY. SERIAL BUS IS READY. BOOT START."
    That is all. Nothing else.
    What is the problem? Memory, power ?
    The photos are in attachment.
    I don't know what to do. What to dig?

    SOLVED
    I remove the PSU from its panel, clean the contacts and mounted it back.
    All became OK. Looks like was not stable power 24v or 110v.
    The problem was solved.
