    [Dead] iR3170Ci refuses to boot, dead LCD, green light

    Hi,

    i have an ir3170Ci Copy-Station which refuses to boot for some time. I have already re-seated all cables and modules and checked the voltages on the main PCB. After powerup the green light on the Panel turns on and stays on. LCD and Keypad are completly dead.
    The Printer seems to perform its initial stuff (moving scanner-head, check paper cartridges and so on.) but never comes up. Network connection is "link up" but no DHCP-Requests or anything else.

    Just before the actual state, it sometimes showed the E748-4000 Error Message. Reseating the rear cable and restarting the machine helped most of the time.

    Thanks in advance!

    bye,
    Karl
