Ok here is the thing I can not say exactly what the error is or was, because this is the first time i have worked on a juke box.
As for the manuals, well i have a 2 part service manaual, as i stated in the first post to this stream I have the manuals and all but one component seems to match what is in the manual. The MCC listed in the manual is a different model than the one in my unit.
And the answer to this was that someone changed it to CDM12 or something like that. So now i need to find a manual that has the correct MCC in it. Right now I am hunting blindly when it comes to the MCC.
Bought the unit as non working. Figured i would cut my teeth on it and see what i can do.
Turned it on, lights started lighting and i figured i was off to a good start.
However it does not index the carriage, it does not move cds does not attempt to load cds.
It was through the use of this forum and from reading my service manual that i have been able to get as far as i have.
I am fairly certain the problem lies in the MCC. Once i replaced those two IC's mentioned before the Board error light now does not light. But now i get the scan trans.
I am thinking and maybe someone can correct me if i am wrong, but if the board is working as it should, the 5v light should be on, and the rowe link tx light should be flashing just like the one on the CCC. Would this be a correct guess?
Because now all i need to do is get the two boards to communicate since i got rid of the board error light. I do know that one of the error codes when displayed while the boards were in the juke box had something to do with communications. Dont recall exactly what it is.
Right now i have the boards here at work with me because here i have my scope and power supplies and other equipment that i dont have at home. And right now on my work bench i have the CCC and MCC tied together. And the light that does not flash or do anything is the rowelink.
I hope that answers your question as to what is wrong with the juke box. All I am doing is taking one step at a time, what works, what does not, what should, what should not, then seeing what i can do to correct what i see.
