Is your 3 digit display on? If not, does the Z LED Flash when rotating the record carrier? If so, you may need to have your computer repaired. If the Z LED doesn't flash, check the 12 volt fuse in the amplifier. If you need your computer repaired or further assistance, please email me, Rod Stebelton, tech@wurlitzer-ohio.com.

I had this problem with my juke box, The rod thet the cd changer goes up & down on gets moisture on it & in return the rod gets small pits of rust on it. I bet you dont have this problem in the summer its always a problem in the winter months with mine.
You need to spray some wd40 on the rod & clean rod with steel wool then you may have to ease the cd holder up in order to clean the rod under the changer.
Give it a go should work.
