    nothing is displayed on the LCD at power–up

    Dear All,

    on a center lathe "Biglia" with Fanuc 21i, when power up only "60M5-04" displayed and then " graphic......." for less than a second appears.
    i can not access the system boot, and on the motherboard one red led "Sfail" is on and the 4 green leds are on.
    could any one help.
