My GBC Ultima 65 is having this bizarre issue. When you press the run button, or any button really, it does whatever it wants. Sometimes it will increase the speed, or run backwards. I've replaced both circuit boards and they'll be done with the exorcism later today. I am running out of options… anyone have suggestions??

Sorry I didnt see this post earlier. I service these machines for a living. Yours should be a EASY FIX:) The membrame switch thats part of the control panel is bad. Replace the switch under 20 bucks and while you have it apart use electrical contact cleaner on the board. at one time the switch contacts were gold and this was a rare problem. when gold got so expensive they began using other materials that corrode a little, and pushing forward often has the machine run backward. if you have futher questions feel free to call me phone help is always free.
