Safety Instructions, Warnings and Notes
2.Safety Instructions, Warnings and Notes
EN 3VAE8015 / 80202.
2.1Safety Instructions
2.1.1General Safety
Safety regulations require that during a repair:
•Connect the unit to the mains via an isolation transformer.
•Replace safety components, indicated by the symbol ,
only by components identical to the original ones. Any
other component substitution (other than original type) may
increase risk of fire or electrical shock hazard.
Safety regulations require that after a repair, you must return
the unit in its original condition. Pay, in particular, attention to
the following points:
•Route the wires/cables correctly, and fix them with the
mounted cable clamps.
•Check the insulation of the mains lead for external
damage.
•Check the electrical DC resistance between the mains plug
and the secondary side:
1. Unplug the mains cord, and connect a wire between
the two pins of the mains plug.
2. Set the mains switch to the 'on' position (keep the
mains cord unplugged!).
3. Measure the resistance value between the mains plug
and the front panel, controls, and chassis bottom.
4. Repair or correct unit when the resistance
measurement is less than 1 MΩ.
5. Verify this, before you return the unit to the customer/
user (ref. UL-standard no. 1492).
6. Switch the unit ‘off’, and remove the wire between the
two pins of the mains plug.
2.1.2Laser Safety
This unit employs a laser. Only qualified service personnel may
remove the cover, or attempt to service this device (due to
possible eye injury).
2.2Warnings
2.2.1General
•All ICs and many other semiconductors are susceptible to
electrostatic discharges (ESD, symbol ). Careless
handling during repair can reduce life drastically. Make
sure that, during repair, you are at the same potential as
the mass of the set by a wristband with resistance. Keep
components and tools at this same potential. Available
ESD protection equipment:
– Complete kit ESD3 (small tablemat, wristband,
connection box, extension cable and earth cable) 4822
310 10671.
– Wristband tester 4822 344 13999.
•Be careful during measurements in the live voltage section.
The primary side of the power supply (pos. 1005), including
the heatsink, carries live mains voltage when you connect
the player to the mains (even when the player is 'off'!). It is
possible to touch copper tracks and/or components in this
unshielded primary area, when you service the player.
Service personnel must take precautions to prevent
touching this area or components in this area. A 'lightning
stroke' and a stripe-marked printing on the printed wiring
board, indicate the primary side of the power supply.
•Never replace modules, or components, while the unit is
‘on’.
2.2.2Laser
•The use of optical instruments with this product, will
increase eye hazard.
•Only qualified service personnel may remove the cover or
attempt to service this device, due to possible eye injury.
•Repair handling should take place as much as possible
with a disc loaded inside the player.
•Text below is placed inside the unit, on the laser cover

1. Flip the module180 degrees, so you can access the PWB.
2. Disconnect the four flex foils from the PWB connectors
(1100, 1300, 1302, and 1303) at the component side. For
the flex foil on connector 1100, you first must remove the
cable clamp [3]. The easiest way to do this is to push down
the two fixation pins of the clamp (via the holes in the PWB)
by means of a pencil or small screwdriver.
3. Disconnect the remaining cables (tray- and fan-motor
cable) at the solder side of the PWB
4. Remove the four screws (Torx 8) that hold the PWB [4].
5. Now you can remove the board.

5.1General
•Impedance of measuring-equipment should be > 1 MOhm.
•For testing the Basic Engine, connect it to a DVD-recorder
of the DVDR1000, 900, or 800 series.
•Most tests are done by software commands. Together with
the software command you will find a Ref.# nbr. This is the
number of the diagnostic nucleus used for this test. You
can find information that is more detailed in the chapter
'Diagnostic Nuclei'.
•Levels: Most measurements are digital measurements.
The signal levels specification in this document are defined
as follows:
– low < 0.3V
– high > 3.0V
– LOW < 0.4V
– HIGH > 4.5V

signals derived in several ICs.
To check whether the program (in the MACE microprocessor)
is running after power 'on', you can monitor the PSEN (OEn of
Flash ROM) on I223 (see test point overview in chapter 6).
You can measure the Servo clocks at I326 (RAdial), I334
(FOcus), and I343 (SLedge).

5.3Diagnostic Software
Due to the complexity of a DVD recorder, the time to find a
defect in the recorder can become long. To reduce this time,
the recorder has been equipped with Diagnostic and Service
software (DS). The DS offers functionality to diagnose the
DVDR hardware and tests the following:
•Interconnections between components.
•Accessibility of components.
•Functionality of the audio and video paths.
This is also valid for the Basic Engine.
One can access this functionality via several interfaces:
1. End user/Dealer script interface.
2. Player script interface.
3. Menu and command interface.
This part describes all interfaces from the outside world to the
diagnostic software, how to use these interfaces, and how to
access them.
First some definitions:
•Diagnostic Nucleus. Part of the Diagnostic Software.
Each nucleus contains an atomic and software
independent diagnostic test, testing a functional part of the
DVD player hardware on component level.
•Script. Part of the Diagnostic Software. Each script
contains a sequence of Diagnostic Nuclei to be executed.
•Service PC. PC used by a service or repair person to
communicate with the Diagnostic Software in the DVD
player.
5.3.1End User/Dealer Script Interface
The End user/Dealer script interface gives a diagnosis on a
stand-alone DVD recorder; no other equipment is needed.
During this mode, a number of hardware tests (nuclei) are
automatically executed to check if the recorder is faulty. The
diagnosis is simply a 'fail' or 'pass' message. If the message
'FAIL' appears on the display, there is apparently a failure in the
recorder. If the message 'PASS' appears, the nuclei in this
mode have been executed successfully. There can be still a
failure in the recorder because the nuclei in this mode do not
cover the complete functionality of the recorder.

Service Modes, Error Codes and Fault Finding
Note: As this mode is meant for a complete DVD Recorder,
and does not add much for testing the Basic Engine, reference
is made to the appropriate DVD Recorder Service Manual for a
detailed description:
•DVDR1000: 3122 785 11600
•DVDR990: 3122 785 12430
•DVDR98x: 3122 785 11970
•DVDR8xx: 3122 785 12200
5.3.2Player Script Interface
The Player script will give the opportunity to perform a test that
will determine which of the DVD recorder's modules are faulty,
to read the error log and to perform an endurance loop test. To
successfully perform the tests, connect the DVD recorder to a
TV set. To be able to check results of certain nuclei, the player
script expects some interaction of the user (i.e. to approve a
test picture or a test sound). Some nuclei (e.g. nuclei that test
functionality of the DVDR module) require that a DVD+RW disc
is inserted. Only tests within the scope of the diagnostic
software will be executed hence only faults within this scope
can be detected.
See note above (paragraph 5.3.1).
5.3.3Menu and Command Interface
Each nucleus contains an atomic and independent diagnostic
test, testing a functional part of the DVD player hardware on
component level. Each Nucleus returns a result message to its
caller. Some tests (e.g. generating a colour bar) can only return
an "OK" result. Internal communication will be done via a
uniform interface between the diagnostic Engine, Scripts, and
the Diagnostic Nuclei.
The Diagnostic Engine can only operate if a certain (minimal)
set of hardware is functioning properly. To test this set of
hardware, a set of basic diagnostic nuclei is embedded in the
DVD player. Each basic diagnostic nucleus will only test that
part of the hardware which is required for execution of the
diagnostic Engine, e.g. a RAM test will only test that part of
RAM that is used by the diagnostic engine. After the Diagnostic
Engine is operational, it is possible to do a full RAM diagnostic.
All basic diagnostic nuclei start with prefix 'Basic'. In the
overview, each Diagnostic Nucleus consists of a reference
number, a reference name, and remarks. Reference number
and name are coupled and one of them is enough for unique
identification.
Nuclei Numeration
Each nucleus has a unique number of four digits. This number
is the input of the command mode.
For testing the Basic Engine, group number 6 is defined
Error handling
Each nucleus returns an error code. This code contains six
numerals, which means:
[ XX YY ZZ ]
Error code
Nucleus number
Nucleus group number
Figure 5-2 Error code
The nucleus group numbers and nucleus numbers are the
same as above.
Hardware required
•Service PC.
•One free COM port on the Service PC.
•Special cable to connect DVD recorder to Service PC.
The service PC must have a terminal emulation program (e.g.
OS2 Warp Terminal, ProComm, or HyperTerminal) installed
and must have a free COM port (e.g. COM1).
Activate the terminal emulation program and check that the
port settings for the free COM port are:
•19200 bps,
•8 data bits,
•No parity,
•1 stop bit,
•No flow control.
Connect the free COM port via a special cable to the RS232
port of the DVD recorder. This special cable will also connect
the test pin, which is available on the connector, to ground (i.e.
activate test pin). Code number of PC interface cable: 3122
785 90017.
Connect the recorder to the mains. The following text will
appear on the screen of the terminal (program):

Circuit Descriptions, Abbreviation List, and Data Shee ts
This section describes briefly the functional behaviour of the
engine. It performs all basic servo functions:
•It reads data from the disc,
•It writes data to the disc,
•It controls all other functions like tray control, start/stop the
disc, tracking, jumping, and communication to the host.
9.2.1Initialisation process
After power-up or reset, a self-test will automatically start.
9.2.2Starting up the drive
After the internal initialisation process has been finished, the
engine will wait for the first S2B user command. E.g.
“Tray_out".
9.2.3Disc recognition process
The process of disc recognition when a disc is loaded is entirely
performed within the engine. Information about the disc type is
send to the MPEG application (back-end).
9.2.4Write / Read process
Depending on the disc loaded and actions to be performed,
Record, Play, Search, etc. a specific sequence of commands is
executed depending on the implementation of the application.
9.2.5Shock behaviour during recording
Shock recovery during recording is performed by the
application if the shock was too large to be absorbed by the
engine. If the engine detects unacceptable servo behaviour,
the laser will go into low power mode to protect overwriting of
neighbour tracks. This action is signalised by the internal
engine controller and reported to the application. The
application can react on this with a shock recovery procedure.
9.2.6Function overview VAE801x and MPEG application
The VAE801x performs all basic servo functions. It reads data
from the disc and writes data to the disc, and controls all other
functions like tray control, start/stop the disc, tracking, jumping,
and communication to the host.
9.3DVD-Mechanism
The DVD-M has an optical pickup unit (OPU) consisting of two
lasers, one for CD with a wavelength of 780 nm, and one for
DVD with a wavelength of 650 nm.
The TZA1032 (LADIC) controls the data from these lasers, and
the supply to them.

9.4.1DROPPI
The DROPPI (DVD Rewritable OPU Pre-Processor IC) is a
multi-purpose analogue pre-processor IC for use in the OPU of
an optical bit engine. The device supports many photo detector
configurations and output signal modes for RF and servo
signals.
Some features of the DROPPI:
•Two inputs:
– Current: DVD photo-diode.
– Voltage: CD PDIC.
•Only one wideband signal across flex foil:
– RF (differential signal).
•Other signals have relatively low bandwidth:
– Wobble signal.

9.4.2LADIC
The LADIC (Laser Driver IC, type number TZA1032) fulfils
three main functions:
•It drives the laser with a sequence of programmable write
strategy pulses with high timing accuracy and high peak
current levels.
•It encodes the input modulated data to a sequence of write
strategy pulses. This encoding is flexible with respect to
input modulation code (EFM, EFM+, 17 pp, etc.). The write
strategy is programmable with high flexibility for CD-R/RW
and DVD-R/RW. For this purpose the TZA1032 includes
two Random Access Memories (RAM) which can be
loaded (non real-time) via the I2C-bus from microcontroller.
•It controls the exact light power levels coming from the
laser and controls the exact power absorbed by the disc
during recording.
The TZA1032 features three independent power supplies.
These are the analogue and digital power supplies and a local
power supply for the laser driver function. The supplies can be
delivered separately to obtain maximum output performance of
the TZA1032 in environments with large and highly dynamic
current flows.
•Dynamic power level control (“Alpha” control, OPC).
•Multi-application.
– Highly programmable (control and write strategy),
– Wide driver & frequency range.
•Under 500 mW dissipation in IC.

9.5.1SPIDRE
The SPIDRE (Signal Processing IC for Dvd REwritable) is a
multi purpose analogue pre-processor IC specifically intended
for writing applications. Its main task is normalisation of the
servo signals that go to the MACE3 servo processor (signals
like 'focus servo', 'radial servo', 'track loss servo', and 'tilt
sensor').
It is possible to optimise the dynamic range of this pre-amp/
processor combination for the LF servo and RF data paths. The
gain in both channels is separately programmable. This will
guarantee an optimal playability for all kind of discs.
The SPIDRE is optimised to work with the optical pick-up unit
pre-processor IC TZA1030 (DROPPI) and decoder IC HDR65.

9.5.2MACE3 Servo and microprocessor
The MACE3 IC (Mini All Cd Engine, type number is SAA7830)
is a combined servo processor and micro controller (80C51).
See also the internal block diagram at the end of this chapter.
The servo front-end
The servo processor handles the signals for focusing, tracking,
and access, but also generates the control signals for the
loader block.
In a CD/DVD system, there are several control loops active.
Some of them are needed to adjust the servo error signals
(once per disc rotation). It also adjusts offsets, signal
amplitudes, and loop gains (AGCs), to enlarge system
robustness and to avoid expensive potentiometer adjustments
in production.
The other loops determine the laser spot position on the disc in
the radial, axial (focus), and tangential directions. It also has to
take care that the spot accesses a required position as fast as
possible. This access system consists of two parts, namely the
actuator and the sled, which are (within a certain range)
mechanically and electrically independent. Therefore, during
an access, the servo has to control as well the actuator as the
sled.
The analogue signals from the diode pre-processor are
converted into a digital representation using A/D converters.
The digital codes are then applied to logic circuitry to obtain the
various control signals.
PCS (Position Control Sledge)
The PCS module is used to get fast sledge access. To achieve
this, it is important that the sledge motor can rotate as fast as
possible. But of course there is a limit to this maximum
rotational speed. In order to let the sledge move even faster the
ratio of the gearing can be reduced. However, if this ratio gets
too low, the cogging/detent torque of the sledge motor will push
the laser 'off track'.
There is a solution to this: Hold the sledge motor in its position
by controlling the voltage on the motor continuously.
PCS is implemented in the following way:
A normal DC motor is used, combined with hall sensors. A DC
sled motor has a magnetic ring mounted around the shaft.
Above this magnetic ring are two hall sensors positioned 90
degrees apart. The two hall outputs, which go to the PCS
control block, are 'sin phi' and 'cos phi'. The system tries to
minimise the phase difference between the measured hall sine/
cosine inputs and a reference sin/cosine waveform.
When the sledge is in tracking, the sin/cosine wave is constant,
so the sledge is kept at its current position. When after a while,
the radial actuator drifts away, the capture point crawls a bit
further on the hall sine. So the PCS makes a micro-step. When
doing an access the servo processor keeps on stepping the
sine/cosine table, thus generating a sine/cosine wave, which
the sledge will follow.
OPC (Optimum Power Calibration)
This device has an integrated Optimum Power Calculation
block for use in CD-R, CD-RW, and DVD-RAM applications. It
Page 38
EN 38VAE8015 / 80209.
Circuit Descriptions, Abbreviation List, and Data Shee ts
reads three analogue signals (A1, A2 and CALF), representing
Max, Min, and Average values of the EFM signal respectively.
It also takes the Power (PW) signal from the laser controller
and then feeds an analogue signal (ALPHA0) out to control the
laser power. The conversion frequency is 88KHz per channel.
Basically, the OPC procedure tries to find out the optimum
laser power to be used on a specific disc. It consists of three
phases:
1. WRITE - Random EFM data is written to the test area of the
disc at increasing levels of laser power (controlled by
ALPHA0).
2. READ - The data on A1, A2, and CALF is read back from
the test area and stored in memory.
3. CALCULATION - the embedded 8051 then calculates the
setting of ALPHA0 where the least jitter is encountered.
Some pre-processing is carried out by the OPC logic to
reduce the processor’s load.
This sequence is done twice - first a coarse calibration,
followed by a fine-tuning.

The micro controller processes the S2B commands from the
DVD+RW interface (back-end), and controls the various
processes in the OPU via I2C. Communication with the
HDR65, SPIDRE, and memories is done via an eight bit
parallel bus.
Some features:
•Dedicated hardwired DSP.
•8051-based microprocessor.
•External Flash ROM and SRAM memory.
The demodulator part detects the frame synchronisation
signals and decodes the EFM (14 bit) and EFM+ (16 bit) data
and sub-code words into 8-bit symbols. Via the serial output
interface, the I2S data (audio and video) go to the DVD+RW
interface (back-end).
The spindle-motor interface provides both motor control signals
from the demodulator and, in addition, contains a tachometer
loop that accepts tachometer pulses from the motor unit. They
drive the motor IC (item 7301).
The SAA7831 has two independent microcontroller interfaces.
The first is a serial I2C-bus and the second is a standard 8-bit
multiplexed parallel interface. Both of these interfaces provide
access to 32 8-bit registers for control and status.
Some HDR65 features:
•Playback speeds up to 48 x CD and 8 x DVD; recording up
to 8 x CD and 4 x DVD
•Matched filter with digital equalizer, noise filter, and digital
PLL.
•EFM and EFM+ modulator and demodulator.
•Decoding, de-interleaving, and error correction according
to CD and DVD standards.
•Wobble processing for DVD-R(W) and CD.
•Motor control for CAV and CLV regulation on both recorded
and unrecorded discs.
•Write data/clock interface compatible with LADIC.
•Versatile serial input/output interface for different formats.
•8 bit parallel data input/output interface.
9.5.4AWESOME
The AWESOME gate array chip (uPD65882, item 7401) is a
fully digital DVD+RW add-on for the HDR65. A combination of
both ICs can do CD and DVD decoding and CD, DVD-R(W),
and DVD+RW encoding. It contains logic for:
•Link bits insertion (according to DVD+RW standard).
•Output to SPIDRE pre-processor for wobble-AGC
It also contains multiplexing logic for the motor signals and a
merge of the internal serial bus to the analogue pre-processor
(SPIDRE) with the serial bus of the HDR65.
•Encoder for DVD+RW. This part creates the EFM+ (16 bit)
signals from the I2S data stream.
•Decoder for DVD and CD. This part processes the HF-
signal from the SPIDRE. It converts the EFM(+) signals to
data, and performs error detection and error correction.
•Output to SPIDRE pre-processor for RF-AGC.
This IC decodes EFM or EFM+HF signals directly from the
laser pre-amplifier, including analogue front-end, PLL data
recovery, demodulation, and error correction.
The analogue front-end input converts the HF input to the
digital domain via an 8-bit ADC, preceded by an AGC circuit to
obtain the optimum performance from the converter. An
external resonator clocks this block. This subsystem recovers
the data from the channel stream. It corrects asymmetry,
performs noise filtering and equalisation, and finally recovers
the bit clock and data from the channel using a digital PLL.

All recordable DVD media types feature a microscopic wobble
groove embedded in the plastic substrate. This wobble
provides the recorder with the timing information needed to
place the data accurately on the disc. During recording, the
drive's laser follows this groove, to ensure consistent spacing
of data in a spiral track. The walls of the groove are modulated
in a consistent sinusoidal pattern, so that a drive can read and
compare it to an oscillator for precise rotation of the disc. This
modulated pattern is called a wobble groove, because the walls
of the groove appear to wobble from side to side. This signal is
only used during recording, and therefore has no effect on the
playback process. Among the DVD family of formats, only
recordable media use wobble grooves.
For lossless linking it is necessary to write any data block in the
correct position with high accuracy (within
1 micron). For this purpose the groove is mastered with a high
wobble frequency (817 kHz at n=1), which
ensures that the writing can be started and stopped at an
accurately defined position. The writing clock as
obtained from this groove is very accurate. At the same time,
address information is stored in this wobbled
groove by locally inverting the sign of the wobbled waveform.
Some characteristics:
•Only exists on (re)writable media.
•Pregroove wobble-detector present in recorders.
•Pregroove wobble-detector not present in players.
•Wobble-frequency is different for different standards:
– DVD+R(W): 820 kHz
– DVD-R(W), DVD-RAM: 141 kHz
•The wobble is phase modulated by inverting wobble
cycles.
•The information contained in the wobble modulation is
called Address-in-Pregroove or ADIP.

Figure 9-7 Power supply overview
The main power supplies to the module are 3.3 V, 5 V, and 12
V (input via connector 1000).
The MACE3, HDR65, and AWESOME ICs use the 3.3 V.
An on-board linear regulator is used to generate the -1.5 V
required by the laser (V
). The other on-board linear
BIAS
regulator is used to generate the 3V3E required by the OPU.
The SPIDRE and OPU use the +5 V and -5 V. The motor, fan,
and servo drivers use the 12 V.
Power 'on' reset
At power 'on', a reset IC (AMD810, item 7201) generates a
positive reset pulse of typicac 240 ms. As a result, the micro
