If you're still having this problem, talk to Al at MyData about replacing the ribbon cable that is wrapped inside the head, and connected to the two LED's. It's a bit of a pain to replace this cable, but, it did fix the problem for us. The other po

I believe I was working with the early MY12 model too. Yes, the X-wagon blue ribbon cable were showing wear and tear very fast. Another frequent break downs were the center-jaw, ribbon broke. Most of the Mydata repairs can be done inhouse with spar
