Hello mountaindew,
When you say it has been changed over to a CD changer is it totally CD? no 45's at all?
Have you caught the video/record switch on the CCC.
I would check the battery voltage on CCC with the power off to check tha it is 3 volts.
If you just have CD I assume that their is some form of interface between the CCC and the CD unit.
