Royal 768 problem


Recommended Posts

Looking at a Royal 768, owner says it displays a error message on display and can't get into menu.


He also told me he replaced board and does the same thing.


He is asking $300 dollars for machine.


I never had this type of problem with any of my Royals or machines.


What would be the problem for machine to display "error"


It has a mars dba and a mars coin mech in machine.

Maybe he doesn't know how to enter the service mode?  Otherwise, maybe the door switch is the issue.  If he doesn't understand the relationship between the door switch and the programming he may think it's broken when it's not.
