Hello again gentlemen,

My Hitachi mill has crapped out and now my lathe is giving issues... great weekend.

The lathe has a Fanuc 3T and the problem is this: when I power on the lathe the screen is blank until I switch to "NC", in FAPT mode there is no display.

The buttons on the FAPT side are lit just no graphics. How separated are the NC and FAPT modes (hardware wise) could it be an analog switching issue between the NC video output and the FAPT video output?

I have never gotten too knowledgable about the inner workings of the 3T (it has "just worked" for over ten years)...

Any help is appreciated,
