SERVICING
For servicing CDR785/CDR786, the sets can be divided into two parts:
1. Except for the Power board (Switched Mode Power Supply) and the CD-R/W module the set has to
be repaired on component level.
2. The Power board and the CD-R/W module will be exchanged completely in case of a failure.
The defective CD-R/W module has to be returned for central repair.
