Hello rpucci,
More than likely the issue with your jukebox will be dry joints (cold joints USA) to the connection pins on the boards, these will be need to be desoldered and resoldered in order for the jukebox to work correctly.
We would check and repair the following boards:-
Power supply PCB
CCC
Mechanism Control Board
Pricing Board
If you are in the USA contact Bruce Wentworth for repairs to the above boards in the UK contact me.
Regards
