Thanks again Ron.......I have a couple of spare Z Controller boards I purchased from a hobby shop in the States about 12 months ago, so I have the controller up and running again, but I would like to repair the "buggered board" if I can.
That is why I was asking if someone knew what the common failure point was in them, and what components I need to get to replace the damaged one/s.
Anyone out there that might have an idea??????
