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'). 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 DR2100. 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.

3. WARNINGS

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.

ATTENTION

Tous les IC et beaucoup d´autres semi-conducteurs sont
sensibles aux décharges statiques (ESD). Leur longévite
pourrait être considérablement écourtée par le fait qu´aucune
précaution nést prise à leur manipulation.
Lors de réparations, s´assurer de bien être relié au même
potentiel que la masse de l´appareil et enfileer le bracelet
serti d´une résistance de sécurité.
Veiller à ce que les composants ainsi que les outils que l´on
utilise soient également à ce potentiel.

WARNUNG

Alle ICs und viele andere Halbleiter sind empfindlich
gegenüber elektrostatischen Entladungen (ESD).
Unsorgfältige Behandlung im Reparaturfall kann die
Lebensdauer drastisch reduzieren.
Sorgen Sie dafür, daß sie im Reparaturfall über ein Puls­armband mit Widerstand mit dem Massepotential des
Gerätes verbunden sind.
Halten Sie Bauteile und Hilfsmittel ebenfalls auf diesem
Potential.

WAARSCHUWING

Alle IC´s en vele andere halfgeleiders zijn gevoelig voor
electrostatische ontladingen (ESD).
Onzorgvuldig behandelen tijdens reparatie kan de levensduur
drastisch doen vermindern. Zorg ervoor dat u tijdens reparatie
via een polsband met weerstand verbonden bent met hetzelfde
potentiaal als de massa van het apparaat.
Houd componenten en hulpmiddelen ook op ditzelfde potentiaal.

AVVERTIMENTO

Tutti IC e parecchi semi-conduttori sono sensibili alle scariche
statiche (ESD).
La loro longevità potrebbe essere fortemente ridatta in caso di
non osservazione della più grande cauzione alla loro
manipolazione. Durante le riparationi occorre quindi essere
collegato allo stesso potenziale che quello della massa
delápparecchio tramite un braccialetto a resistenza.
Assicurarsi che i componenti e anche gli utensili con quali si
lavora siano anche a questo potenziale.

6.3.1 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. The units are : the CDR main
board, the CDR loader, the CD loader in case of a DR6050 and
the keyboard/display board. A sequence of tests is executed
automatically. Some of the te sts can be aborted or skipped
without the result being taken into account. External tools or
disassembly of the unit is not necessary to get the diagnostic
information. Pressing keys [ENTER] and [CD STOP].
simultaneously while switching on the unit, starts the test.
Switching off the unit ends the test.

6.3.2 Requirements to perform the test

A CD-DA disc with a minimum of 3 tracks in all trays to

perform the disc test.

6.3.3 Description of the tests

disc test is executed to check focus control, disc motor control,
radial control and jump grooves control. The d isc test is
performed by audio play-back of 5 seconds at the beginning,
middle and end of the disc.

CDR loader test

During the test, the current disc time is shown. In case of an
error the message "BERR1" will be displayed and the [F FWD]
key must be pressed to continue with the following test.
Pressing the [F FWD] key also aborts this test.

CD loader test

During the test, the current disc time is

shown.

In case of an error the message "BERR2" will be

displayed and the [F FWD] key must be pressed to continue
with the following test. Pressing the [F FWD] key also aborts
this test.

Display test

All segments will blink at a frequency of 1 Hz. Pressing the [F
FWD] key will start the next test because the user has to check
for himself if all segments work properly.

Player information

In this part of the test the following important information can be
checked without removing the cover :
Recorder ID.
SW-version back end of player.
SW-ver sion CDR loader.
SW-version CD loader.

CDR main board test

[F FWD] key. The message "DERRn" will be displayed with n
indicating the faulty test number.
If one of the tests is aborted with the [F FWD] key, no error
message will be displayed for this test. The flash data erase
test ("DTST3") can not be aborted !
The CDR main board test consists out of :

DRAM test

Display : "DTST1". The DRAM used for buffer management is
tested by writing, reading and verifying test patterns.

Flash checksum test

Display : "DTST2". This test checks the checksum of the
player's SW stored in the flash.

Flash data erase

Display : "DTST3". During this test, all temporary information
(CDtxt) in the flash is erased.

CODEC (ADC/DAC) test

Display : "DTST4". This test checks the CODEC IC by writing,
reading and verifying test patterns.

CDR communication test

Display : "DTST5". The communication between the host
processor (DASP) and the CDR loader via the DSA-R-bus is
tested.

Load CD-RW disc

Press

<ENTER> + <MENU/STORE>

simultaneously and switc h

ON unit

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. The
format is "ER mm:ss", where "mm" are the remaining minutes
and "ss" the remaining seconds. After completion the message
"PASSED" is shown, and the player has to be switched off and
on again to start up in normal operating mode. Switching off the
unit before completion of the test, leaves the disc in an
unpredictable state. In such case only a complete DC-erase
procedure can recover the CD-RW disc.

8.1.1 Description of display board

General description

The display board has three major parts : the LCD (Liguid
Crystal Display), the display controller and the

The display controller is controlled by the DASP master

processor on the CDR main board. The communication

protocol used is I2C. So all the information between DASP and
display controller goes via the SDA or I2C DATA and SCL or
I2C CLK lines. Communication is always initiated by the DASP
on the CDR main board. Unlike the previous generations of
CDR players, the interrupt generated by the display controller
at key-press or reception of remote control is not used. Instead,
the DASP polls the display controller for these events.

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%.

I2C DATA/I2C CLK

These lines connect to the DASP master processor via
respectively pin 5 and pin 7 of conn. JU02

. When there is no
communication, they should have the high level (+5V). The
oscillogram below gives an indication of how these signals
should look like.

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). When the remote control is being

operated, pulses mixed in with the +5V can be measured. The
oscillogram gives an indication of how the signal looks like with
the RC being operated.

8.3 CD Main Board

The CD main board is built around the compact disc
mechanism MAR1250 and a loader 1250. The CDM delivers
diode signals and an unequalised high frequency signal. These
signals are necessary inputs for the decoder CD10. Based on
these signals the decoder will control the disc. The decoder is
able to control the sledge, focus motor, radial motor and turn
table. When everything is "locked", the decoder delivers a
digital output according to IEC958 standard, subcode to the
microprocessor and I2S for reproducing analog audio signals
by means of a D/A converter.

8.3.1 Supply Voltages

Description

The CD main board receives +5V and +12V from the CDR main
board via respectively pin 16 and pin 15 of connector 1208. The
+5V is split up into +5VHF and +5V. The +5VHF is used mainly
for the diode currents and the HF-amplifier. The +5V is used for
the digital part of the board. On the board a +3V3 is made from
the +5V for the decoder CD10 and an A3V3 for the DAC
UDA1320. The +12V is split up into A12V for the audio output
stage and +12V for the power drivers of the CDM.

Measurements

Connect following supplies to next pins :

+5V + 5% to pin 16 of connector 1208.
+12V + 5% to pin 15 of connector 1208.
Ground reference to pin 17 of connector 1208.

8.3.2 Clock Signals

Description

The microprocessor has its own Xtal or resonator of 12MHz.
The CD10 needs a clock of 8.4672MHz + 100ppm. This speed
also relates to the disc speed. To avoid locking proble m s
between the two drives in the CDR775, both drives run on the
same clock. Therefore the CD main board gets the clock for the
decoder from the CDR main board via pin 2 of connector 1208.
The DAC needs a system clock to drive its internal digital filters
and to clock the I2S signals from the decoder. In our case this
is 11.2896MHz (CL11) generated by the CD10.

Measurements

Connect the power supply as described above in "1.1.1.

Supply Voltages".

8.3.5 BA6856FP Turn Table Motor Driver (7020)

Description

This component is a 3 phase, full wave pseudo linear driving
system with inbuilt Hall Bias circuit and 3 phase parallel output.

Measurements

Keep processor 7202 in reset by forcing pin 7 of connector
1208 to +5V. The outputs 9, 10, 11 of connector 1006 are 0V.
Pin 21 of the motor driver 7020 is 2.5V 10%.
Pin 22 of the motor driver 7020 is 2.5V 10%.
Pin 23 of the motor driver 7020 is 0V.
Pin 19 of the motor driver 7020 is 5V

10%.
Put the processor out of reset to continue the measurement.
Check MOT1 at pin 59 of CD10. The duty cycle of the output
should be 50%. Check wave form at pin 11 of 7005-D :
amplitude 5V + 5% duty cycle 50%.
The motor driver 7020 can be measured dynamically by
connecting a hall motor to the application panel. Apply a pulse
of 1V 10Hz and 15% duty cycle to pin 22 (Ec) as input value
with reference to pin 21 (Ecr=2.5V). Measure the output signals
on the driver. This will give as response a square wave on pin
17 and pin 18. When a positive voltage is applied, the square
wave on pin 17 will go ahead of the square wave on pin 18.
All signals will have a value as shown in the truth table. Check

Description

The tray control consists of a TDA7073A power driver (7021)
controlled by the processor 7202 via pin 19 TRAYIN and pin 20
TRAYOUT. If pin 20 is low and pin 19 high, the TRAY+ signal
at pin 16 of 7021 is forced to +8V and the TRAY- signal at pin
13 of 7021 to GND : the tray will open. If pin 20 is high and pin
19 low, TRAY+ becomes GND and TRAY- becomes +8V : the
tray will close. If pin 19 and 20 of the processor have the same
value, TRAY+ and TRAY- will have the same value as well : the
tray stops moving.

Measurements

Keep procesor 7202 in reset by forcing pin 7 of connector 1208
to +5V. Connect a load of 15 , 7W between pin 3 and 4 of
connector 1002. Check the voltage over the load with TRAY+
(pin 3) as positive reference. Check also the levels of pins 19
and 20 of the processor.

8.3.7 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. The signal will then follow

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).

8.3.8 Audio Part - DAC

Description

The DAC used, is the UDA1320 bit stream, continuous
calibration. I2S signals from various formats can be entered at
pins 1,2 and 3. If these signals are in phase with the delivered
system clock at pin 6, the DAC will reproduce analog output
signals at pins 14 and 16. 0dB level is 0.85Vrms. These analog
signals are at 1.65Vdc level.
The DAC has features which can be checked on the input pins.
Mute will switch off the analog signals. De-emphasis is not
used, since this is done in the decoder. Attenuation of -12dB is
not used because this is also done in the decoder.

I2S

I2S is a kind of digital audio format, consisting out of 3 lines :
CLOCK, WORDSELECT and DAT A.

signal is in phase with the WS-signal. Transition of the WS
always happens on a falling edge of the CLK.

DATA

DATA contains all data-bits. Data bits are set by the
transmitting device, and read by the receiving device. The
position of the DATA-bits within the WS-signal is very
important. There are several formats for this. In our case we
always use Philips I2S format, no Japanese or Sony format.
The number of data-bits per channel depends on the used
devices.

Timing of the I2S-bus, in case of Philips I2S is shown in the
next figure :

LEFT SAMPLE RIGHT SAMPLE

WORD-SELECT

Word select (WS) indicates whether the data-sample is from
the left or the right audio-channel. It has the same frequency as
the sample rate of the digital audio signal. This can be 32, 44.1
or 48kHz. Normal polarity is low for a left sample and high for a
right sample. So within the low state of the WS-line the data bits
for the left channel are transferred, and within the high state the
data bits of the right channel are transferred.

CLOCK

The CLOCK signal (CLK) indicates when DataTips must be
set, and when DataTips must be read. The frequency depends
on the speed of the I2S-bus, but is always a factor of the

frequency of the WS-signal. It can be 48x, 64x, 96, 128x... .In

our case it is 48x the sample rate frequency = 2.1168MHz. The

Keep processor 7202 in reset by forcing pin 7 of connector
1208 to +5V. 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.
Connect via an I2S generator I2S-signals to the DAC :
Pin 1 at 7309: SLCK.
Pin 2 at 7309: WCLK.
Pin 3 at 7309: DATA.
Connect also the SYSCLK pin 6 at position 7309 to a clock

±

signal of 11.2896 MHz

Generate an I2S signal equivalent with a sine wave of 1kHz at
0dB for both left and right channels.
Check if 0.8 VRMS at pins 14 and 16 at location 7209 with a
DC of 1.65VDC.
Check if 1.7 VRMS

Force MUTE Pin 11 at 7309 high.
Measure again at pins 1 and 3 at location 1209 : both signals
should be at -90 dB.
