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 Switching Power Supply Board.

This PCB contains the Power Supply, which delivers the sevelal volteges for the each PCB in the CDR631. On this Power
Supply a fuse (Primaly side) are mounted on this PCB. The power SW is jointed the Power bottom on the front panel.
All parts are available as spare parts.

1.2.3 Audio Board.

This PCB contains the audio part,witch takes care that the signal from CDR main module is converted into an analog signal
via DA converter and outputs the analog signal. This PCB contains the output and input connectors also. 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.

5.1.1 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 CDR500 and
the keyboard/display board. A sequence of tests is executed
automatically. Some of the tests 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 [PLAY/PAUSE] and [F FWD]
simultaneously while switching on the unit, starts the test.
Switching off the unit ends the test.

5.1.2 Requirements to perform the test

• Working keyboard to start up the test.

• Working local display to check the output messages.

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

perform the disc test.

5.1.3 Description of the tests

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-version CDR loader.

• SW-version CD loader (only for CDR500).

CDR main board test

As soon as the CDR main board tests are finished, all failure
messages (if any) will be displayed sequentially by pressing the
[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. The test is not applicable for
CDR950.

CDR communication test

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

CD communication test

Display : "DTST6"). The communication between the host
processor (DASP) and the CD loader is tested. The test is only
applicable for CDR500.

Loader tests

These tests determine if the CDR loader and the CD loader in
case of a CDR500 work correctly. A CD-DA disc with a
minimum of 3 tracks needs to be inserted in both loaders. A
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.

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

For CDR500 only. 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.

Keyboard and remote control tests

The test will give the user the ability to test every key without
executing the function assigned to it. Therefore, the user needs
to press every key on the keyboard and the remote control. The
display will show the name of the key being pressed. Pressing
more than one key at once will give an unpredictable result
except for the service combinations : [PLAY/PAUSE] + [STOP],
[PLAY/PAUSE] + [ERASE] + [RECORD], [PLAY/PAUSE] +
[RECORD].

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.

7.1 Display Board

7.1.1 Description of display board

General description

The display board has three major parts : the FTD (Fluorescent
Tube Display), the display controller TMP87CH74F and the
keyboard. 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.

Display controller TMP87CH74F

TMP87CH74F (QY01) is a high speed and high performance
8-bit single chip microprocessor, containing 8-bit A/D
conversion inputs and a VFT (Vacuum Fluorescent Tube)
driver.
In this application, its functions are :

• slave microprocessor.

• FTD driver.

• generates the square wave for the filament voltage
required for an AC FTD.

• generates the grid and segment scanning for the FTD.

• generates the scanning grid for the key matrix.

• input for remote control.

All the communication runs via the serial bus interface I2C. The
display controller uses an 8Mhz resonator as clock driver.

7.1.2 Test instructions

Supply voltages

The display board receives several voltages via connector
JY01.

• VFTD : -34V ±5% measured at pin 2 of conn. JY52.

• VDC1-VDC2 : 4V1 ±10% measured between pin 1 and 3 of
conn. JY52.

• +5V : + 5V ±5% measured at pin 10 of conn. JY52.

Voltages VFTD, VDC1 and VDC2 are produced in the Switching
Power Supply Board and sent to the display board via the CDR
main board. The +5V voltage is produced on the CDR main
board as D5V.

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%.

Grid lines

Level and timing of all grid lines, G1-->G15, can be checked
either at the FTD itself or at the display controller. Grid lines
G13, G14 and G15 each have an extra current amplifier in line
: QY04 for G13, QY03 for G14 and QY02 for G15. A typical
grid line signal shows in the oscillogram below.

PM3392A

Control signals

RESETN

The reset signal comes via pin 4 of conn. JY52 from the DASP
master processor on the CDR main board (SYS_RESET). The
reset is low active. It should be kept low during power up for at
least 3 machine cycles with supply voltage in operating range
and a stable clock signal (1 machine cycle = 12 x 1/Fc (8 Mhz)
sec.). During normal operation, the reset should be high (3V3).
The high signal is 3V3 because the DASP operates on 3V3.

I2C DATA/I2C CLK

These lines connect to the DASP master processor via
respectively pin 5 and pin 7 of conn. JY52. 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.

Key matrix lines

The lines connected to pins 18, 19, 20, 34, 35, 36 and 37 of the
display controller act as matrix scanners. Without a key pressed,
they maintain a low level. As soon as a key is pressed, the
scanning line connected to that key puts out a scanning signal,
which should look like the oscillogram below. This scanning signal
goes via the pressed key to I/O port 7 of the display controller
(pins 28 to 33). The display controller can now determine which
key has been pressed. Without a key pressed, pins 28 to 33 of
the display controller maintain a high level (+5V).

display controller), maintain the +5V level. Turning the knob

Figure 7-7 TURN ANTI-CLOCKWISE

The pulses created this way arrive at pin 16 and 17 of the
display controller. The first pulse to arrive tells the controller the
direction of the rotation. Counting the pulses reveals the
amount of rotation. Combining and decoding this information,
the display controller will execute the appropriate task.

Push button operation

This button connects to the key matrix lines and thus the
operation is identical to the ordinary keys. Without being
pressed, pin 4 of the easy jog maintains the low level, pin 5 the
high level. When pressed the scanning signal goes through the
closed contact of pins 4 and 5, and can be checked at both
pins.

IR receiver - remote control

In the CDR631 the IR receiver ZY01 is mounted on the IR board.
In all versions the IR receiver connects to the display controller.
The signal coming from the receiver can be checked at pin 22 of
the display controller. 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.

7.2.3 Digital in/out paths

There is a cinch digital-in paths and an optical path taking the
digital signals pretty much straight to the DASP on the CDR
main board. The optical-out and the digital-out path take the
signal from the DASP on the CDR main board to their
respective output connectors on the I/O board.

7.3 Headphone board

The L and R analog signals coming from the analog output on
the I/O board pass an adjustable amplifier (opamp Q901) after
which they are passed on to the headphone connector. The
amplification is adjusted by means of a potentiometer
positioned at the front of the CDR player.

7.4 Power Supply Unit P816

7.4.1 Description of P816

MOSFET Q825 is used as a power switch controlled by the
controller Q810. When the switch is closed, energy is
transferred from mains to the transformer. This energy is
supplied to the load when the switch is opened. Through
control of the switch-on time, the energy transferred in each

cycle is regulated so that the output voltages are independent
of load or input voltage variations. The controlling device
MC44603 is an integrated pulse width modulator. A clock
signal initiates power pulses at a fixed frequency. The
termination of each output pulse occurs when a feedback
signal of the inductor current reaches a threshold set by the
error signal. In this way the error signal actually controls the
peak inductor current on cycle-by-cycle basis.

Figure 7-18 ‘Blockdiagram P816’

Description of controller MC44603

The MC44603 is an enhanced high performance controller that
is specifically designed for off-line and DC-to-DC converter
applications. This device has the unique ability of automatically
changing operating modes if the converter output is
overloaded, unloaded or shorted. The MC44603 has several
distinguishing features when compared to conventional SMPS
controllers. These features consist of a foldback facility for
overload protection, a standby mode when the converter output
is slightly loaded, a demagnetization detection for reduced
switching stresses on transistor and diodes, and a high current
totem pole output ideally suited for driving a power MOSFET. It
can also be used for driving a bipolar transistor in low power
converters. It is optimised to operate in discontinuous mode but
can also operate in continuous mode. Its advanced design
allows use in current mode or voltage mode control
applications.

A voltage delivered by an auxiliary transformer winding provides to the demagnetisation pin an indication of the
magnetisation state of the flyback transformer. A zero voltage detection corresponds to complete core
saturation.

9 Synchronisation

Input

The synchronisation input pin can be activated with either a negative pulse going from a level between 0.7V and

3.7V to Gnd or a positive pulse going from a level between 0.7V and 3.7V up to a level higher than 3.7V. The
oscillator runs free when Pin 9 is connected to Gnd.

Operating description of MC44603

The input voltage Vcc (pin 1) is monitored by a comparator with
hysteresis, enabling the circuit at 14.5V and disabling the
circuit below 7.5V. The error amplifier compares a voltage Vfb
(pin 14) related to the output voltage of the power supply, with
an internal 2.5V reference. The current sense comparator
compares the output of the error amplifier with the switch
current Isense (pin 7) of the power supply. The output of the
current sense comparator resets a latch, which is set every
cycle by the oscillator. The output stage is a totem pole,
capable of driving a MOSFET directly.

t1: Charging the capacitors at Vcc
C829 will be charged via R823 and R832, C833 and
C811 v ia R829. The output is switched off during t1.
t2: Charging of output capacitors
When the input voltage of the IC exceeds 14.5V, the circuit is
enabled and starts to produce output pulses. The current
consumption of the circuit increases to about 17mA, depending
on the external loads of the IC. At first, the capacitors at the Vcc
pin will discharge because the primary auxiliary voltage,
coming from winding 7-9 is below the Vcc voltage. At some
moment during t2, the primary auxiliary voltage reaches the
same level as Vcc. This primary auxiliary voltage now
determines the Vcc voltage.
t3: Regulation
The output voltage of the power supply is in regulation.
t4: Overload
When the output is shorted, the supply voltage of the circuit will
decrease and after some time drop below the lower threshold
voltage. At that moment, the output will be disabled and the
process of charging the Vcc capacitors starts again. If the
output is still shorted at the next t2 phase, the complete start­and stop sequence will repeat. The power supply goes in a
hiccup mode.

The voltage at the current sense terminal is compared every
cycle with the output of the error amplifier Vcomp. The output

t4

is switched off when the current sense level exceeds the level
at the output of the error amplifier.
TimeON phase : A drain current will flow from the positive
supply at pin 2 of the transformer through the transformer's
primary winding, the MOSFET and Rsense to ground. As the
positive voltage at pin 2 of the transformer is constant, the
current will increase linearly and create a ramp dependent on
the mains voltage and the inductance of the primary winding. A
certain amount of energy is stored in the transformer in the form
of a magnetic field. The polarity of the voltages at the
secondary windings is opposite to the primary winding so that
the diodes are non-conducting in this phase.
TimeDIODE phase : When the MOSFET is switched off,
energy is no longer supplied to the transformer. The inductance
of the tranformer now tries to maintain the current which has
been flowing through it at a constant level. The polarity of the
voltage from the transformer therefore reverses. This results in
a current flow through the transformer's secondary winding via
the now conducting diodes, electrolytic capacitors and the load.
This current is also ramp shaped but decreasing.
TimeDEAD phase : when the stored energy has been supplied
to the load, the current in the secondary windings stops flowing.
At this point, the drain voltage of the MOSFET will drop to the
voltage of C821 with a ringing caused by the drain-source
capacitance with the primary inductance.
The oscillator will start a next cycle which consists of the above
described three phases. The time of the different phases
depends on the mains voltage and the load.
TimeDEAD is maximum with an input of 400VDC and a
minimum load. It will be zero with an input of 100VDC and an
overload.

Circuit description of P816

Input circuit

The input circuit consists of a lightning protection circuit and an
EMI filter.
The lightning protection comprises R819.

The EMI filter is formed by C820, L820, C825 and C826.

It prevents inflow of noise into the mains.

Primary rectifier/smoothing

The AC input is rectified by rectifier bridge D802 and smoothed
into C821. The voltage over C821 is approximately 300V.
It can vary from 100V to 390V.

Start up circuit and Vcc supply

This circuit is formed by R823, R834, C829, D828, R829,
R811, C833 and C811.
When the power plug is connected to the mains voltage, the
stabilised voltage over D829 (24V ) will charge C833 via
R829. When the voltage reaches 14.5V across C811, the
control circuit of Q810 is turned on and the regulation starts.
During regulation, Vcc of IC7110 will be supplied by the
rectified voltage from winding 7-9 via L832, D832 and C833.

Control circuit

The control circuit exists of Q810, C802, C804, C807, C809,
C810, R802, R803, R804, R807, R808, R809 and R810.

C802 and R810 define the frequency of the

oscillator.

Demagnetisation

The auxiliary winding (7-9) voltage is used to detect magnetic
saturation of the transformer core and connected via R801 to
pin 8 of Q810. During the demagnetisation phase, the output
will be disabled.

Overvoltage protection circuit

This circuit consist of D814, C814, R814, R815 and R816.
When the regulation circuit is interrupted due to an error in the
control loop, the regulated output voltage will increase
(overvoltage). This overvoltage is sensed at the auxiliary
winding 7-9.
When an overvoltage longer than 2.0 (s is detected, the output
is disabled until VCC is removed and then re-applied. The
power supply will come in a hiccup mode as long as the error
in the control loop is present.

Secondary rectifier/smoothing circuit

There are 5 rectifier/smoothing circuits on the secondary side.
Each voltage depends on the number of windings of the
transformer.
The -8V supply is regulated by voltage regulator Q871.

On/off circuit

Power switch circuit

This circuit comprises MOSFET Q825, Rsense R826, R827 and
R828, R825, C827, L825, R812 and R813. R825 is a
resistor to remove static charges from the gate of the

pull-down

MOSFET.

Regulation circuit

The regulation circuit comprises opto-coupler Q801 which
isolates the error signal from the control IC on the primary side
and a reference component D881. The TL431(D881) can be
represented by two components:
a very stable and accurate reference diode
a high gain amplifier

TL431 will conduct from cathode to anode when the reference
is higher than the internal reference voltage of about 2.5V. If the
reference voltage is lower, the cathode current is almost zero.
The cathode current flows through the LED of the opto-coupler.
The collector current of the opto-coupler flows through R806,
producing an error voltage, connected to voltage feedback pin
14 of Q810.
