Bizhub 600, lcd freezes sometimes

[fixthecopier]

The customer says that they cannot input the acess code, screen will not respond. When I got there it was working, but they said we have been there before for the same thing. It is working when we show up, but I have no doubt it is locking up on them. Solutions database says to reseat the card on the ICB, any other ideas??

We had one that would lock up everything, only a restart would fix it. I replaced the ICB about 2-3 weeks ago and I haven't heard of any call backs. We tried firmware first, then reseating the card.
