18、11.Servicing the CDR6311.1 INTRODUCTION:The CDR631is the professional version of a CD recorder , this means that the SCMS (Serial Copy Management System) isnot included. The CDR631can record on the Audio and CDRs PC.The CDR631is suitable for recording and playback of CD-R W discs (CD-Re Writable dis

19、c).1.2 OPENING THE PRODUCT:The product can be opened by removing the top cover (8 screws). Once the product is opened one can have access to theseveral PCBs and the main module. To have access to the Display PCB, the Headphone PCB first the front cover has tobe removed.Below the several PCBs and it

22、CDR LOADERSWITCHING POWERSUPPLY BOARDAUDIOBOARDDISPLAY BOARDHEADPHONEBOARDMOTERBOARD21.2.1 CDR loader (CDR main module CDL4009 or MAR770):This complete CDR loader is considered as not repairable in the field. therefore this module will be repaired centrally. Amodule exchange procedure will be set up

23、 for this purpose. The module can be removed from the product by removing 4screws and the transformer (see demounting the CDR module on page 1-7), and loosing the connectors.This module is the complete CD recorder, it contains the following parts:CD Mechanism (CDM4009). Underneath this mechanism a P

24、CB is mounted which is adjusted to the mechanism (lasercurrent settings are stored in EEPROM).Loader Assy. This mechanical assy takes care for the tray control.Main PCB. This PCB takes care that the (analog or digital) signal to be recorded is converted into a suitable signal whichcan be recorded on

25、 the disc.Digital signals with an other sampling frequency then 44.1kHz will be converted in the sample rate converter (DASP) to44.1kHz.Analog signals will be first converted into a digital converter by the AD converter.This PCB also takes care that the signal from the CD (playback) is converted int

26、o a suitable digital signal (or analog viathe DA converter).The main microprocessor controls the several functions of this PCB. 1.2.2 Switching Power Supply Board.This PCB contains the Power Supply, which delivers the sevelal volteges for the each PCB in the CDR631. On this Power Supply a fuse (Prim

27、aly side) are mounted on this PCB. The power SW is jointed the Power bottom on the front panel. All parts are available as spare parts.1.2.3 Audio Board.This PCB contains the audio part,witch takes care that the signal from CDR main module is converted into an analog signal via DA converter and outp

28、uts the analog signal. This PCB contains the output and input connectors also. All parts are available as spare parts.1.2.4 Display Board.This PCB contains the Display, which informs the user about the status of the recording/playback process and it also takescare for scanning the keys on the front

29、panel. The information from the keys is fed via a I C connection to the mainmicroprocessor on the CDR loader module. Information which needs to be displayed is also fed via this I C line from themain microprocessor on the CDR loader module to the display controller.The parts for this PCB are availab

30、le as service parts so this PCB can be repairable up to component level.1.2.5 Headphone Board.This PCB contains the headphone socket and potentiometer which controls the headphone volume. All parts are available as spare parts.22IMPORTANTIn case of replace the CD-R module MAR770, the initialization

31、is necessary.Please initialize the CD-R module with following orders.1. Press the POWER button (POWER ON) while depressing FINALIZE button and RECMODE button together.2.
