    Default Fanuc-18P No Display!! No Boot !Pl help Status LED meaning?

    hello! There are many Fanuc Gurus Around !! I need your help Please.

    The display at my Amada Vipros 255 with Fanuc 18P control is not turning ON. It Flickers to show that LCD has Power..but No Text display. The status LED (green) at the Main board - g1,g2g3,g4 are all green. but Immediately below Three LED's the Middle one is RED. Any amount of resetting does not help. The power supply conditions are just fine. Checked the 3 phase, 220V, 24 V ..fine..Wiring from CRT ~CPU. Checked Fuses etc. at CRT and display card all fine.
    Can anyone help me figure out the meaning so that we can know what is wrong.
    The CPU on the machine is A16B-3200-0210-04B; When searched the same board is used by Fanuc 18TC/18 MC also.
    Changed the Power supply Unit of CPU no improvement..Someone told me to replace SRAM board.changed..no Improve.. changed LCD no improvement..Any help is welcome.
    I have Panels to punch for my LED's Housings but Got Stuck bad..real bad. Customers banging my head now...
    - I have found the Error LED meaning and Attached the Info here please view and comment.

    Hi LedForLess,

    Have you verified the cables are ok? If they are, you may want to consider trying another CPU. It's possible that it could be the problem.

    Good luck, and let me know how everything goes?

    Dear sir,
    I changed the CPU to a New one .but I could not find a fully populated cpu. so the Bare CPU board we cahnged, and we swapped all the sum- modules into that CPU. No change. We checked cables too. no apparent dagage.
    Can this be because of CRT module of the CPU or the FROM module ? or the SRAM shall i get new ones in? Thanks for your answer.
