I have a ss bally freedom here.. went through the mpu, driver, power boards a few years ago. Been perfect untill now.
One day, powered on and mpu not booting( led not on or blinking) and displays are blank of course but can see a orange dot so i know they have h.v.
A test of the power supply shows .400v at tp3. Other voltages are correct. Checked and rechecked fuses, all check good. From what ive checked, this tp3 is supposed to be around 12 volts dc. I back tracked to the rectifier(br2) and i have no ac to the rectifier. This is supposed to be supplied with 12vac from the transformer. I pulled up the board form the transformer, and i see no broken connections. I have no ac even at the fuse.
I think i have a bad transformer, do you guys agree? Ever see one fail like this?
