Re: Yamaha rx v373 - no power

I have the same model with similar problem although I have a regulator with 4 pins and one pin measures 11.5v one ground one 3.3 volts and one 1.5 volts. The power switch is switching 3.3 volts to ground when pushed but nothing lights up. If i short the 12 volts to the pwr ry point I here the relay on the input board close but still nothing lights up. I guess I really need a schematic. Anyone know where one can be had.
