    IR Advance C7055 E748-2042

    The C7055 was stuck and a reset showed a black screen with the error message:
    E748-2042

    The manual indicated that it is one of
    Hard drive
    Main Controller 1
    Main controller 2

    Box test refuses to run


    I pulled the HDD and it checked OK using Seagate SeaTools.

    I swapped MCON 1 from a junked C7065, transferring all components from the original board, as per the manual.
    • DDR2-SDRAM (2 pc.)
    • Flash PCB
    • TPM PCB

    Now box test runs and returns OK.

    Machine now boots but halts with error
    E355-0004

    This indicates a serial number mismatch between several components. Resetting the error from level 3 menu doesn't clear the error.

    Question. Is it possible to swap a used Main Controller Board 1 from a C7065 to this C7055? Is there a certain procedure for doing so?
    If I install a new Main Controller Board 1, is there a certain procedure for installing it? The manual indicates only that I need to transfer DDR, Flash PCB, and TPM PCB.

    Please advise

    Thanks.

          Because of different model , so you must replace maincontroller1,2 and all of small pcb at sametime, Some small PCB not place on Maincontroller, but somewhere on machine
