hi i have a midi keyboard and it wont power on. so i opened it and used my multimeter to test it. one wire, the black one connected to the board reads 9.16v(6 1.5v size C batteries), the other reads 0. this happens when the power switch is on. nothing happens when it's off. on the solder points of the switch, there are six points in 2 rows of three one row reads 0.06 - 0.08v and the other reads nothing. does anyone thing they can help? there's a slideshow of it here:
