Lego Mindstorms NXT motor port failure?
I just dug out my Lego Mindstorms NXT 2.0 (it was buried under some stuff) and I decided to play with it. I had built it into a "Robogator" model, and I went to test the jaws, and.... nothing. The motors didn't turn at all. They just locked in place. I replaced the batteries, tried test programs, updated the firmware, and even opened up the NXT, but I couldn't find anything wrong. Also, the motors worked when i connected two together and turned one. I called Lego support, but their answer was to just buy a new one. Anyone have any idea how to fix this?
