16、adioFans.CN 收音机爱 好者资料库Servicing the DR-171. INTRODUCTION:The DR-17 is the consumer version of a CD recorder, this means that the SCMS (Serial Copy Management System) isincluded. The DR-17 can only record on the Audio CDRs (Consumer Use).The DR-17 is suitable for recording and playback of CD-RW discs

17、 (CD-Re Writable disc).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 and the lever PCB first thefront cover has to be r

21、 repairable in the field. therefore this module will be repaired centrally. Amodule exchange procedure will be set up for this purpose. The module can be removed from the product by removing 10screws and the transformer (see demounting the CDR module on page 1-7), and loosing the connectors.This mod

22、ule is the complete CD recorder, it contains the following parts:CD Mechanism (CDM3610). Underneath this mechanism a PCB 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 tak

23、es 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 sampling frequency then 44.1kHz will be converted in the sample rate converter (GDIN) to44.1kHz.Analog signals will be first converted into a

24、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 viathe DA converter).The main microprocessor controls the several functions of this PCB. The system software stored in a normal DILEPROM(7322).

25、 This EPROM(7322) is mounted on a socket, so software updates can be easily done at the dealer orservice agent.2.2 Power SW Board.This PCB contains the Power SW, which is jointed the Power bottom on the front panel. All parts are available as spareparts.2.3 Power Supply and Audio Board.This PCB cons

26、ists of power supply part and audio part. The power suppluy part delivers the several voltages for the diffrentPCB in the DR-17. On this power supply sevel fuses (secondary side) are mounted on this PCB. The audio part takes carethat the signal from CDR main module is converted into an analog signal

27、 via DA converter and outputs the analog signal.This PCB contains the output and input connectors also. All parts are available as spare parts.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

28、 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 line from themain microprocessor on the CDR loader module to the display controller.The parts f

All parts are availableas spare parts.2.6 Analog Input BoardThis PCB contains the analog in

30、put (RCA) connector. All parts are available as spare parts.2.7 Level Board.This PCB contains the potentiometer to adjust the level of the analogue input signal. All parts are available as spare parts.2.8 Moter Board.This PCB takes care for the tray speed control. All parts are available as spare pa

31、rts.221-23. TEST PROGRAMS.The DR-17 has two built in test programs. These are the “Dealer Diagnostics” and the “Service Diagnostics”. Bothdiagnostics can be used to determine which board or module is defect.3.1 Dealer Diagnostics.This test diagnostics the communication between the several ICs in the

32、 CDR module. To start the test press the buttons+ simultaneously and switch on the power.During this diagnostics the message “BUSY” is blinking on the display (this can last for a couple of minutes). When an erroris detected the message “ERROR” is displayed. For the meaning of this error the service

33、 diagnostics has to be ran.Since no CD is used for this test, the playback and record parts of the module are not tested thoroughly.3.2 Service Diagnostics.This Diagnostics tests the main board and CDM assembly (also known as Basic Engine) of the CDR module and thekeyboard and display board.If an er

34、ror is detected, an error number is displayed which refers to the error.The test is executed with a normal CD loaded, so the recording part of the CDM is not tested thoroughly.To start the test press the keys + simultaneously and switch the power on.See the attached sheet for a flowchart of the “SER
