I have a Rowe MMCD-1 Jukebox (circ 1994) bought second hand for my rec room. The kids got into it and zapped something such that it no longer functions, i.e. CD's don't play.
Wading thru the manuals, the error codes point at the mechanism controller which is an 80c31 based micro. I've been able to verify the solenoid and motor drivers are still functional by grounding specific points in the control logic. The error code indicates there is no communication between the mech control and main controller. I've replaced the 75176 driver in the mech controller and main controller with no joy yet.
At power-on the error lamp flashes once, but should flash 3-times. Anybody know what this is trying to tell me? I already know it doesn't work. ;)
thanks for the input
