I have on old Sterex SX-B unit that is in need of repair. When I turn on the power the light for thermolysis always lights up but to get galvanic to work as well I need to turn it on and off several times. The problem persists when I use the foot pedal to turn it on and off. Any ideas what the problem could be?
Also, I can’t send it to Sterex for repair because of my location. What sort of repair shop would be able to fix this? Somewhere where they do general electronics?
