Respuesta a "Showing it is charging, but no powder. Does not switch on.?"Had the same problem, charging but not working. When I disassembled found that the area underneath the on/off switch, HA-703X, was getting hot. Because of the accumulated dust in the switch the contact was not fully made when pressed and the dirt with the efect of humidity was acting like a resistor and blocking the current to flow freely and getting self heated instead. Searched the net for replacement unit but no use. Soaked the switch with WD42 several times and kept it soaked for some time, now it is working. But I am not sure for how long that will last. Still looking for a replacement switch.
