Technical Specifications/Introduction.

1. Technical Specifications/Introduction.
In this document the important issues for the mechanical and electrical testing, adjusting, checking and diagnosing of the Digital Audio CDR Module such as applied in so-called 3rd generation CDR recorders is described. In this first chapter is presented the introduction of the repair manual for 2nd line repair workshops. In contains the repair instructions of the CDR Module CDL4009 + Mainboard 4228. All modules consist of the same loader + CDM part, the mounting of the components on the Mainboard deviates form each other. For that reason a separate CDR-module has been defined for each type/modelnumber. On top of that: Each mainboard connected to another CDM has to adjusted before that module can be used. To have this module on component level repaired this second line service (repair) manual has to used in combination with the "first" line service manual of mentioned typenumber. As long as the adjustment instructions can not be carried out, the module has to be exchanged by an adjusted one from Service stock in case of repairs concerning CDM and/or Servo circuits. Chapter 2 contains the required safety instructions, in chapter 3 a referring to the directions for use, as published in the typenumber Service Manual, is made. In chapter 4 the mechanical exploded view of the complete module, the loading part and the CDM3800 is presented. This chapter also includes the mounting, demounting, cleaning and greasing instruction. In chapter 5 the internal selfdiagnostics without opening the set and use of other tools is described in the service modes. The faultfinding trees and repair suggestions like the power supply voltages for proper functioning of the mainboard are indicated there too. This chapter also contains initialising and reset, concerned measuring points are highlighted. For proper functioning of all ICs the clockfrequencies have to be tested and the importance of derived clockfrequencies is shown. and and how to operate with the menu driven diagnostics. Via a PC connection (serial input socket RS232C) the Menu Driven Diagnostics feature is started. To improve the interactivity and communication with the set/ module the COMPAIR (the for service designed computer aided repair) tool is supported too by this CDR generation. Details to be defined soonest and will be published by a service information bulletin later on. Via blockdiagrams of applied boards the common issues of all boards are shown and in short explained in chapter 6. In chapter 7 the circuit diagrams and printed wiring boards with important measuring points are shown. The adjustment of the laser current (only one important and necessary adjustment has to be carried out, the rest of the adjustments are calcultated from that parameter onwards) will be presented in chapter 8. The needed PC program is under investigation now and with the implentation of COMPAIR this adjustment action will be explained. The method how to align the software, if needed, is indicated here. In chapter 9 reference is made to existing 3rd generation circuit description in which publication a lot of details about the functioning of the set is explained. Also the list of abbreviations is inserted here. Finally a survey of applied components and corresponding service ordering numbers is given in chapter 10. As the Mainboard 4228 is designed to be applied for several modelnumbers this board contains a lot of optional components. The most extended board is modelnumber CDR775 where double speed dubbing feature is applied too.

GB WARNING NL WAARSCHUWING

All ICs and many other semi-conductors 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 wrist wrap with resistance. Keep components and tools also at this potential.

Alle IC's en vele andere halfgeleiders zijn gevoelig voor elektrostatische ontladingen (ESD). Onzorgvuldig behandelen tijdens reparatie kan de levensduur drastisch doen verminderen. 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

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

Alle IC und viele andere Halbleiter sind empfindlich gegen elektrostatische Entladungen (ESD). Unsorgfältige Behandlung bei der Reparatur kann die Lebensdauer drastisch vermindern. Sorgen sie dafür, das Sie im Reparaturfall über ein Pulsarmband mit Widerstand mit dem Massepotential des Gerätes verbunden sind. Halten Sie Bauteile und Hilfsmittel ebenfalls auf diesem Potential.

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

GB
Safety regulations require that the set be restored to its original condition and that parts which are identical with those specified be used.

I
Le norme di sicurezza esigono che l'apparecchio venga rimesso nelle condizioni originali e che siano utilizzati pezzi di ricambiago idetici a quelli specificati.

F
Les normes de sécurité exigent que l'appareil soit remis a l'état d'origine et que soient utilisées les pièces de rechange identiques à celles spécifiées.

SHOCK, FIRE HAZARD SERVICE TEST: CAUTION: After servicing this appliance and prior to returning to customer, measure the resistance between either primary AC cord connector pins (with unit NOT connected to AC mains and its Power switch ON), and the face or Front Panel of product and controls and chassis bottom, Any resistance measurement less than 1 Megohms should cause unit to be repaired or corrected before AC power is applied, and verified before return to user/customer. Ref.UL Standard NO.1492. NOTE ON SAFETY: Symbol : Fire or electrical shock hazard.

Cleaning objective lens
CLEANING PRESCRIPTION OBJECTIVE LENS · Cleaning fluid The lens cleaner codenumber reads 4822 389 10026 · Procedure · Take a clean cotton wool tipped stick and put Lenscleaner on the wool. · Wipe the lens very softly with the wet wool end of the stick by moving it forwards and backwards in the Ydirection. (see drawing) · Take a dry cotton wool tipped stick and remove the Lens-cleaner from the lens by moving it very softly back and forth in the Y-direction (see drawing) · During cleaning, take the necessary precautions in order to prevent damage to the*Actuator (hinges, lens, litze-wires) or OPU (ESD, ...) Do not remove axle (item 4, see drawing) from OPU, because the fixing screws of axle are deforming it at it's end. On their turn these deformings are damaging the hinges of the OPU when loosening the axle. · Application This cleaning procedure is only applicable for the flat side (upside) of the lens. Never try to clean the round side (underside) of the lens (replica-side). With this cleaning procedure, fingerprints and dust can easily be removed with very soft and gently movements of the cotton wool tipped stick. · Limitation This cleaning procedure is only applicable in cases of malfunctions of the product, due to lens-problems. It's not ment to be applied on 100% of the actuators, OPU's. After cleaning, the product must be re-checked on it's functionality. Figure 4-9

MECHANICAL SERVICE DIAGNOSTICS
(test for defective components)

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 CDR775 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. 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. 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 CDR775). 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. 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 CDR775. Loader tests These tests determine if the CDR loader and the CD loader in case of a CDR775 work correctly. A CD-DA disc with a minimum of 3 tracks needs to be inserted in both loaders.

Power supply part on mainboard · Description. The most important part of an electrical function is the power supply. Without it will never operate. The power supplies as well analog as digital equipment. For these reasons the power supply is split-up in different sections. One for the digital electronics, one for the servo controls and one for the AUDIO part. The servo controls are the big consuming parts with high peak-currents, also introducing disturbances in the power lines. The audio part needs very "clean" power, because noise and ripples have there reflection in the audio signals, specially in S/ N and THD+N. Some of the power supplies are switched off, this to reduce consumption in case of standby. The different power supplies are delivered to the PCB via connector 1500 This is a 11 pole connector with following voltages on it: +5V, +12V, -8V, VFTD, VDC1 and VDC2. The last 3 voltages are not used on the main PCB, but are meant for the FTD (Fluorescent Tube Display). They are directly routed to connector 1705. The other voltages are split up in different functions on the PCB. The following block-diagram gives an indication of that implementation.

Reset & Clock Master reset. Since the Mainboard is more or less mix-mode between +3V3 and +5V devices, special treatment for the RESET behavior is wishful. Controlling the RESET only from 1 power supply could lead to collisions between different devices, damaging the internal I/O structure of the devices. To avoid this the +3V3 and the +5V are guarded by a special device. These devices keep the output low as long as the power supply is not stable or is not above the required level. As soon as the power supply is stable it switches the output to "HIGH-Z". The output is an open collector type. From then onwards the line can be controlled by means of external pull-up resistors. Benefit of the opencollector devices is that several of those devices can be tight together at the outputs. In our case we used a device on the +5V and one on the +3V3. This means that both power supplies need to be stable before the RESET of the Master processor is released. Resetting several processors in the same structure by means of the power supplies invokes certain risks. The duration of initialization after reset is processor and Code depending. It can lead to hang-up in those cases that communication between the processors is "time" driven. Meaning that only in a certain time frame the establishment of the communication-bus must take place. If not successful the Bus hangs! To avoid these kinds of problems, only 1 RESET is depending on the power supply, and this is the RESET of the Master controller. The same master controller will then take care of the RESET of the other devices. In the next figure this is explained.

The clockgeneration All microprocessors or digital devices need a clock. The clock is usually made by means of resonators or crystals depending on the speed and the accuracy that is requested. The clock can also differ from device to device so that more then one crystal is needed. The cheapest and "system wise" best way is only 1 crystal. The derived clocks are then Phase related to each other. On the CDR MAIN 99 the DASP is generating all clock signals. Not only the systemclock for the processor itself, but also for the basic engine processor and even the systemclock for the ADDA part which is directly related to the 44.1kHz. sample frequency. To be able to do this a 33.8688Mhz. crystal with 25ppm accuracy is connected to the internal oscillator of the DASP. Internal the clock signal is multiplied by means of a PLL. This gives the systemclock on which the processor runs internally. This systemclock is then again devided internally to have the systemclock for the ADDA, which is 11.2896Mhz, and the 16,9344Mhz. which divided by 2 gives the systemclock for the BE part. In this way only 1 crystal is required. The same 8.4672MHz. is also routed to the CD-module in case of a CDR775 player.

NOTICE:THE TESTS, AS PROVIDED BY THE MENU DRIVEN DIAGNOSTICS, ARE NOT SUPPOSED TO BE MIXED RANDOMLY, ESPECIALLY TESTS LIKE `LASER ON' AND `FOCUS ON'. IT IS ASSUMED THAT THE PERSON THAT USES THE MDD KNOWS IN WHICH ORDER THESE TESTS CAN BE EXECUTED. The MDD module communicates with two entities: the terminal emulator on the PC. The MDD receives instructions (test to be executed) and transmits the menu to be shown and the test results; the Audio Engine module. It instructs the Audio Engine via the interface field which test should be executed. The test result is retrieved from the interface field. Requirements The functionality of the Menu Driven Diagnostics module is to implement Menu Driven Diagnostics for service purposes. When the CDR recorder is connected to a PC via an interface board 7104 086 91111, connection cable 3104 157 11122 and a RS232 cable (available at PC shop), the service technician can select via a menu on the PC screen which test should be perfomed. The result of the test is also shown on the PC screen. No special test tool is needed for the PC; any terminal emulation program can be used (for example, HyperTerminal under Windows95/NT). The last occurred error during a test session can be retrieved via the menu. The RS232 connector should be soldered to pins: 1818-1 = Rx 1818-4 = Gnd 1818-2 = Tx General Constraints It is advised to connect the connection cable 3104 157 11122 to the Mainboard connector 1818 mounted just under the loader (topview). Via this cable also the powersupply for the interface board 7104 086 91111 is arranged when it is connected to connector 1000 on interfaceboard. To start this application at powering on; for 5 seconds the Rx and Tx output pin of the mainboard connector should be short circuited. This temporarily short circuit indicates the internal CDR software program to switch onto Menu Driven Diagnostics. This short cut can easily be done via the switch (1009) on the interface board. To communicate with the PC the RS232 cable has to be connected to output connector 1010 on the interface board and the switch (1009) should be released. When switching on the CDR, two possibilities exist: the RS232 cable is not connected. The application is executed (no MDD mode); the RS232 connector is connected; Rx and Tx are short circuited for more than 5 seconds then the Menu Driven Diagnostics is started. By connecting via connection cable to interface and from there via the RS232 cable onto the PC, so the MDD can transmit the main menu to the PC.

Figure 5-14 PC help on mainboard diagnostics A couple of the diagnostics are only possible with the help of a PC. The DASP micro controller will contain an interface with the external world; this interface is realised via a serial RS232 connector that is accesible inside the player. It can be accessed from the outside world by means of test pins and connector 1818 and interface board 7104 086 91111. Via those test pins a terminal emulator can be connected. Then menus will come up that give the opportunity to enter all Audio Engine commands. This includes the commands on Bit Engine Level (transparant). This terminal emulator functionality is part of the embedded software, so no external software is needed. It can also read out the User Profile Logging of Bit Engine. This can show the hours that the loader really was in recording mode. This diagnostic tool is activated if communication is detected on the RS232 interface during power up. The baud rate for both is 19k2 baud. Details of the diagnostic tool are given in chapter 5.2.3 of this publication: Menu Driven Diagnostics. Also in preparation is the interactive COMPAIR tool. Then the PC communicates in an active form with the set and compares the result for making the next decision. With MDD the technician has to take the next active step from his experiences onwards. 5.2.3 Menu Driven Diagnostics In this paragraph the specification of the software requirements for the Menu Driven Fault Finding Diagnostics is given. It will give a clear and unambiguous description of what the Menu Driven Diagnostics (MDD) do.

User Interfaces RS232 interface The CDR recorder transmits the menu to be shown and the test results to the PC via connection cable 3104 157 11122, interface board 7104 086 91111 and a RS232 cable. It receives the selection of the user, chosen in the menu.

Data Communication Interfaces Communication between the CDR recorder and the PC is straightforward: everything the CDR recorder transmits to the PC is shown on the PC screen. Data, transmitted from the PC to the CDR775, is treated as a choice from the currently shown menu. All functionality of the MDD has to be part of the CDR775 software; the PC can only use a terminal emulation program. Menu Structure and Test Results This chapter describes the structure of the menus and the results of the tests, as shown on the PC screen. Menu Structure When starting up, the PC screen is cleared and the software version and the main menu (level 1) are shown. From the main menu, one of the sub menus (level 2) can be selected. These sub menus contain other sub menus and/or a number of tests that can be executed. The menus are shown below. `>>' indicates that when this option is selected, a new menu will be shown.

Three types of tests exist: Tests that return PASSED or FAILED, like the DRAM test. When a test has been executed, the result is showed on the PC screen; Tests that return a value, the message `PASSED, xxx' (with xxx is the returned value) is showed on the PC screen; Tests that don't return anything, like the `laser on' test. Most of these tests require a visual check of the service person. When one of these tests is executed, `PASSED, visual check' is showed on the PC.

8. Alignments & Adjustments
Each CDR-module composed from CDRloader and CDRmainboard has to be matched via SW filled parameters.This adjustment processed in the factory is under investigation to have it implemented into the COMPAIR tool. As long as this adjustment is not possible to be executed in secondline service workshop, the swop of modules and a central repair has to be continued. Adjustment only has to be done at replacement of CDM and concerned servo circuits. Other repairs (audio signals, replacement of adapted Flash roms etc) can be done without infringing the adjusted components. As soon as COMPAIR CDR is installed this chapter will be adapted via a service information. Flash Rom IC 7208 (MACE-ROM) is mounted on a socket and can be replaced after lifting up the loader part above it. Flash Rom IC 7703 (DASP-ROM) has to be soldered. Take care for both ICs Firmware loaded components are mounted. In case a module is offered with SW versions 1.4 and 91.48, the complete CDR-module should be replaced. For SW versions 1.23 and 91.63, IC7703 and IC7208 have to be replaced by the latest SW verions.
