Thanks for your post! A hard one to answer with such little information, which model do you have? With the unit not charging it could be one of three things, the charger, battery or pcb (inside the machine). Do you have a basic multimeter to help out? The bottom line answer is that, it is repairable and probably cost effective. Shout if we can help further!
