Servicing the DR60501.1 INTRODUCTION:The DR6050 is the consumer version of a CD recorder, this means that the SCMS (Serial Copy Management System) isincluded. The DR6050 can only record on the Audio CDRs (Consumer Use).The DR6050 is suitab

19、le for recording and playback of CD-RW discs (CD-Re Writable disc).1.2 OPENING THE PRODUCT:The product can be opened by removing the top cover (6 screws). Once the product is opened one can have access to theseveral PCBs and the main module. Below the several PCBs and it function and service policy

Amodule exchange procedure will be set up for this purpose. The module can be removed

23、 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 PCB is mounted which is adjusted to the mecha

24、nism (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 the disc.Digital signals with an other samp

25、ling 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 into a suitable digital signal (or analog viath

26、e DA converter).The main microprocessor controls the several functions of this PCB. 1.2.2 Power Supply PCB.This PCB contains the Power SW, which is jointed the Power bottom on the front panel. This PCB consists of power supply part. The power suppluy part delivers the several voltages for the diffre

27、nt PCB in the DR6050. On this power supply one fuse (primary side) is mounted on this PCB. All parts are available as spare parts. 1.2.3 Terminal PCB.This PCB coutaius input and output terminals. All parts are available as spare parts.1.2.4 Display Board.This PCB contains the Display, which informs

28、the user about the status of the recording/playback process and it also takescare for scanning the keys on the front 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 l

29、ine from themain microprocessor on the CDR loader module to the display controller.The parts for this PCB are available as service parts so this PCB can be repairable up to component level.1.2.5 Headphone PCB.This PCB contains the headphone socket.22IMPORTANTIn case of replace the CD-R module MAR775
