    it could be sram card issue. if you already have sram backuo in hand, remounting sram card to make better seat contact to the socket.

    boot in IPL mode, check the sram.
    if the sram is in ok condition (backup/restore without error) try to boot normaly if it still doesnt boot
    so you have cpu card or main board problem
