Not working...no sound, no movement

I noticed one evening that the lights on top of the carousel were blinking in an usual manner. They next day the unit didn’t come on…no sound, no movement. I then ran another transformer to the unit, and nothing. I took it apart and ran a volt meter to the computer board…apparently it IS getting power. Do you think it is the circuit board? If so, can i purchase another one? Any other ideas??? Thank you! Mike
