1. Servicing the DR2100 1.1 INTRODUCTION: The DR2100 is the consumer version of a CD recorder, this means that the SCMS (Serial Copy Management System) is included. The DR2100 can only record on the Audio CDRs (Consumer Use). The DR2100 is suitable for recording and playback of CD-R W discs (CD-Re Writable disc).
1.2.1 CDR loader (CDR main module CDL4009 or MAR775): 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 and loosing the connectors. This module is the complete CD recorder, it contains the following parts: CD Mechanism (CDM4009').

3. WARNINGS ESD WARNING All ICs and many other semiconductors are susceptible to electrostatic discharges (ESD). Careless handling during repair can reduce life drastically. When repairing, make sure that you are connected with the same potential as the mass of the set via a wristband with resistance. Keep components and tools at this potential. WAARSCHUWING Alle IC´s en vele andere halfgeleiders zijn gevoelig voor electrostatische ontladingen (ESD).

6. DIAGNOSTICS SOFTWARE 6.1 Dealer mode 6.2.2 Working keyboard to start up the test. Working local display to check the output messages. The purpose of the dealer mode is to prevent people taking out the CD inside the player at exhibitions, showrooms etc.. This mode disables the open/close function of the player. The dealer mode can be switched on and off pressing keys [OPEN/CLOSE] and [STOP] of the CDR player simultaneously while switching on the unit.

6.3.1 disc test is executed to check focus control, disc motor control, radial control and jump grooves control. The disc test is performed by audio play-back of 5 seconds at the beginning, middle and end of the disc. Description The intention of the electrical service diagnostics is to show the software versions present in the player and to direct the dealer towards defective internal units.
6.4.2 Requirements to perform the test 6.5.1 Working keyboard to cycle through the tests and to start up the test. Working local display to check the output messages. 6.4.3 This test is initiated by pressing [ENTER] and [MENU/STORE] simultaneously while switching on the unit. The player will erase a complete CD-RW disc (including PMA and ATIP lead out area) at speed N=2. The display shows the countdown of the remaining time required for the operation to complete.

8.1.2 Test instructions Clock signal As clock driver for the display controller, a resonator of 8 MHz (XY01) is used. The signal can be measured at pins 8 and 9 of the display controller : 8 MHz ±5% . IR receiver - remote control In the DR2100 the IR receiver RPM6934 (ZY83, ZY84) is mounted on the display board. In all versions the IR receiver connects to the display controller. The signal coming from the receiver can be checked at pin 3 of conn. JU05. This signal is normally high (+5V).

another amplification and filtering circuit. The filtering again is controlled by the S1 and S2 lines, dependant on whether the disc starts up (speed n=1, S1 and S2 Low), disc plays at speed n=1 (S1 Low, S2 High) or disc plays at speed n=2 (S1 and S2 High). HF Path Description The pre-amplified HF-signal is presented to both n=1 and n=2 amplifier circuits. The mux/demux switches via software and micro processor controlled S1 and S2 lines between either one of the amplified n=1 or n=2 signals.

This puts the processor outputs in tristate. Check the reset at pin 4 of processor 7202 to make sure that the processor is in reset. Now, force port 0-4 pin 33 at 7202 to 0V to set the decoder outputs (SCLK, WCLK, DATA, and CL11). Check the MUTE pin 11 at 7309 : this pin should be low.
