Looking for VC4046 and M4103

Hi, I had trouble with my turntable (Microseiki DDX-1500 - early version) which spins backward when stop button is pressed. In the circuit board there are 2 IC - VC4046 and M4103 which I think might be the cause of trouble. Does anyone know where to get datasheets for these or get parts for it?
Thanks a lot, guys.
