I started troubleshooting this machine awhile back but knee replacement surgery kept me out of the shop for a few weeks. I'm getting around better now and resumed working on this juke.
I have determined it was stored in a very damp environment. To date I have replaced the K7 actuator, removed and freed up the frozen carrier motor, replaced one fuse in the amp.
Upon power up I have a dead display, and the gripper motor loads, then unloads, the carousel rotates, stops and the gripper motor repeats the same process.
This is my first OMT encounter other than replacing K7 actuators for customers which I have done a few of those. Looking for advice on where to go next with this one.

Hi Rick,
Slide the Selection & Credit Computer's Service Switch to "ON" and then press the "LT button to the right of it a bit on the same computer. This puts the computer into self test. Display should show the EPROM version. If the display still shows nothing make sure the ribbon cable is plugged into the S&CC correctly - ribbon goes to the left.
Now that you are in Self Test you can read the manual and try various tests like Keyboard Button 7 = Cycle Gripper, Keyboard Button 6 = Rotate Carousel, etc.
Do the tests work?
