I recently had that “Both axes, no response” message. Before deciding I had a blown MB, I did a bit of detective work. I had recently done a strip and clean followed by installing a belt mod. In the course of setting the RA worm I had to loosen off the little control panel - several times. I decided to check all the connections behind it and discovered one of the wires from the hand control had come loose and also, the On/Off rocker switch was not working properly - an intermittent fault. A little soldering and a replacement switch and reassembled it. And everything worked fine. No more nasty messages. So before leaping in and ordering a new MB, it might pay to check these simple things first.
