1. Servicing the DR6050

1.1 INTRODUCTION:

The DR6050 is the consumer version of a CD recorder, this means that the SCMS (Serial Copy Management System) is

included. The DR6050 can only record on the Audio CDRs (Consumer Use).

The DR6050 is suitable for recording and playback of CD-R W 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 the

several PCB's and the main module.

Below the several PCB's and it function and service policy will be discussed:

BOARD

1.2.1 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. A

module exchange procedure will be set up for this purpose. The module can be removed from the product by removing 4

screws 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 mechanism (laser

current 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 which

can be recorded on the disc.

Digital signals with an other sampling frequency then 44.1kHz will be converted in the sample rate converter (DASP) to

44.1kHz.

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 via

the 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 diffrent 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 the user about the status of the recording/playback process and it also takes

care for scanning the keys on the front panel. The information from the keys is fed via a I C connection to the main

microprocessor on the CDR loader module. Information which needs to be displayed is also fed via this I C line from the

main 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.

IMPORTANT

In case of replace the CD-R module "MAR775", the initialization is necessary.

Please initialize the CD-R module with following orders.

1. Press the POWER button (POWER ON) while depressing FINALIZE button and REC

TYPE button together.

2. FL Display shows;

PGM PORT END

3. Press the POWER button (POWER OFF).

Then the CD-R module set up to DR6050 own status.
