Almost all non-working IIci's need the capacitors replaced on the logic board. As time passes, pretty much all of them are going to need this. So any IIci's you buy are either going to need to have it done, or have already had it done. If you have failed IIci's that's likely to be the problem. Of course, the other likely problem is failed power supplies, but since those are easily swappable, that's pretty obvious from a trouble- shooting point of view. Anyway, replacing the capacitors is not especially difficult. In an industrial environment such as yours, I would be surprised if you don't have several people who are handy with a soldering pencil. Much discussion of replacing the logic board capacitors is available in the forums over on 68kmla.net. The gist is: 1) The surface mount electrolytic capacitors leak corrosive goo eventually. 2) The corrosive goo can destroy circuit board traces and vias and appears to be at least somewhat electrically conductive, as evidenced by the fact that washing it off is often enough to get a board working again, temporarily. 3) Replace the surface mount electrolytics with surface mount tantalums. They won't leak goo. 4) The stripe on the electrolytics indicates the negative terminal. The stripe on the tantalums indicates the positive terminal. The confusion from this has resulted in many popped tantalums. 5) If you don't have special soldering equipment, the easiest way to remove the surface mount capacitors is to use two soldering pencils. One on each side of the cap to be removed. 6) Be patient! Most lifted pads and torn traces are caused by folks trying to remove a capacitor before the solder is fully melted or any glue underneath is softened.
