I have a treadmill Proform 730cs. When 1st starting up at any speed the console will go blank at the same time the mc-60 controller shuts down. The current limit D16 never comes on but D6 D7 and D11 all go out for a short time and come back on the same time as the console powers back up. I am convinced the motor, power board, belt and incline motor are all ok by tests. Any ideas ??
