SERVICING
For servicing CDR779, the set can be devided into three parts
1. The display board (partly) 1002, the I/O board 1004, the
headphone board (partly) 1002, the IR board (partly) 1002, the
ON/OFF & Standby LED board (partly) 1002 and the CD-out
board (partly) 1002 have to be repaired at component level. The
power supply unit 1003 is available as spare part, but can also be
repaired at component level.
2. The CDR module (containing the CDR loader 81, CDR main
board 1001 and loader bracket 82, 83) can also be repaired at
component level with the help of COMPAIR release 1.6 and
higher. With this tool the diagnosing of the set can be done in an
interactive way. In the tool also the adjustment procedure has
been implemented. This is absolutely necessary in case the CDR
mainboard and/or (CDR loader) CDM is disconnected from the
matched production combination. Only designated workshops
can perform these repairs. Please send the complete set to the
designated workshop.
3. The CD module (containing the CD loader 131, CD mainboard
1005 and loader bracket 132) is a new module with VAL1250
loader assy but also a separate CDM and separate loader parts
will be available via service stock. The CD mainboard can be
repaired at component level.
