Hello, I have a Sam light (Pac Fab) with the colorwheel.  It stopped rotating a couple of years ago, and I finally got around to changing the motor and gear inside.  I put it all back together and tried it.  It seems that there is no signal from the PCB to activate the motor to turn.  Are there replacement circuit boards for this light, or should I consider replacing the entire fixture?  I wish it had a standard socket so I could just replace with an LED retrofit, but I have those 2 small halogens instead.
