Nothing lights up when pushing on the « power » button. I already cleaned the pads and the rubber of the button. I got my hands on a schematic that starts at the 9V jack to the C105 capacitor. I measured 8,8V on this capacitor when the power button is pushed down. I assume that the problem is somewhere down the line. Does anybody have the complete schematic ?
