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.
ESD
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.
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.
AVVERTIMENTO 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. 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.

5.3.1 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 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.
Loader tests These tests determine if the CDR loader and the CD loader in case of a DR6050 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 CDR775 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] + [F FWD], [F FWD] + [REWIND], [ERASE] + [RECORD], [PLAY/PAUSE] + [RECORD].
5.3.2 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.
5.3.3 Description of the tests

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 : -30V ±5% measured at pin 2 of conn. JY01. · VDC1-VDC2 : 4V3 ±10% measured between pin 1 and 3 of conn. JY01. · +5V : + 5V ±5% measured at pin 10 of conn. JY01. Voltages VFTD, VDC1 and VDC2 are produced in the I/O Board and sent to the display board via the CDR main board. The +5V voltage is produced on the CDR main board as D5V. +4V 0V 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.

RESETN The reset signal comes via pin 4 of conn. JY01 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. JY01. 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 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 4 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).

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 DR6000 the IR receiver ZY01 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 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.

Rotary operation The easy jog knob (SY26) incorporates a whole heap of user control possibilities in just one knob. Without the knob being operated, pin 1 and 3 of the knob (and thus pin 16 and 17 of the display controller), maintain the +5V level. Turning the knob clockwise briefly connects pin 1 to GND followed by pin 3.

7.2.1 Analog-in path
Description The via cinch connected anolog-in L and R signals are preamplified by opamp Q701 after which they are presented to an adjustable amplifier made out of DS1807 and opamp Q706. The level of the incoming analog signal is adjusted by means of control lines "I2S" coming from the DASP on the CDR main board and switching the mux/ demux. The anolog signal is then presented to the A/D converter A5351 (Q703) where they are converted from analog to I2S-bus data format. The I2S-bus is connected via connector JJ01 and flex to the DASP on the CDR main board. The ADC uses the CL11-clock (11.2896 MHz), coming from the DASP on the CDR main board. ADC AK5351 Description The AK5351 is a stereo, 20-bit oversampling ADC based on Sigma Delta technology intended primarily for digital audio bandwith applications. It supports the I2S-bus data format. The device can be used in either slave or master mode. In this application it is used in slave mode receiving it's clock from the DASP on the CDR main board.
