Great service. The manual was exactly what I was looking for: schematic + layout. I managed to fix the player. Highly recommended!
 ;
At $5,00 certainly good bang for your buck. Includes electric schematics as well as exploded parts view + parts list for reordering. Unfortunately no details on the PCB contents or working, but then again, this is not overly complex. Best bonus: this manual does contain the heavily searched for LED error codes as well as descriptions for test operation. Haven't gotten around to fixing the machine yet, one thing the manual won't do for you is getting it out of the kitchen assembly :-(
;
It`s not your fault tear down is rather incomplete. It doesn`t have complete instructions as to deconstruction for repair.

THANK YOU FOR A GOOD TRANSACTION, NICE COPY, CLEAR

Very Good! All the diagram are easy to read, and its complete.
