Connector 1705 is an option for the usage of SACD1000 set only for connecting monoboard to front panel board. Connector 1701 is also an option for the monoboard power supply 12V/ 5V/3V3 in case of the requirements needed for further improvement on audio performance of SACD. Connector 1014 is for either DCU (Diagnostic Controller Unit) or BST (Boundary Scan Test) used by industrial only.

Safety Instructions, Warnings, and Notes

2. Safety Instructions, Warnings, and Notes

2.1 Safety Instructions

2.1.1 General 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 h,

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.

2.1.2 Laser 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).

2.2 Warnings

2.2.1 General

• All ICs and many other semiconductors are susceptible to

electrostatic discharges (ESD, w). 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’.

2.2.2 Laser

• 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 shield:

4.2 Service Hints

4.2.1 DVD Module

This module can be repaired as follows:

1. The VAL6011/14 is a combination of loading mechanism and DVD-mechanism. Both the mechanism is not a repairable unit and in case of failure it has to be replaced with a new loader VAL6011/14.

Note: When replacing with a new VAL6011/14 two solder joints have to be removed after connecting the OPU flex foil to the board. The solder joints which shortcircuits the laser diodes to ground are for protection against ESD. Refer to Figure 4-5 and Figure 4-6 for location of solder points.

Mechanical Instructions

Test Instructions Mono Board DVD-SD5.00SA_CH

5. Test Instructions Mono Board DVD-SD5.00SA_CH

5.1 General

• Impedance of measuring-equipment should be > 1MΩ.

• Most tests have to be done by software commands.

Together with the software command you will find a Ref.# nbr. This is the number of the diagnostic nulceus used for this test. More detailed information can be find 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

• All the waveforms measurement carried out in these test instruction will be base on the testpoint indicated in the Monoboard schematic diagram in the service manual.

5.2.2 Reset Check:

To ensure a proper start-up of the monoboard, the back-end reset signal RESETn is required at the STi55xx input (testpoint F906) after power-on. To check the reset timing, measure the RESETn (testpoint F906) and the +3V3ST supply (testpoint F784), reset circuit trigger signal.

The module operates in power-off and power-on only. There is no standby mode at module level. In power-off, the module does not response to any communication or signals. Before starting the measurement, ensure that all power supply are connected to the monoboard via connector 1703 or 1701 and that the PC interface cable is connected to the Service interface connector 1500 of the monoboard.

Now start the terminal program. Make sure that the service-pin (pin 1500-2) of the µP is pulled low. The terminal program of your PC should now display: “DVDv4 Diagnostic software version ...”. This message already means that the µP is running. The first 5 commands from the diagnostic software will be carried out automatically during diagnostic start-up. The other commands can be carried out by selecting the “command input” and simply type the reference nbr. to do the test or select the “Menu - driven” test. To be sure that the µP is able to run the diagnostic software, serial port will be checked during start-up.

5.3 µP Environment:

5.3.1 General:

All the tests are carried out by software tests. To start the software tests, connect a PC to the serial bus of the STI55xx. Use connector 1500 for this connection:

EN 14 SD-5.00SA_CH5.

Test Instructions Mono Board DVD-SD5.00SA_CH

5.3.2 Memory Check:

The µP has a data bus that is connected to a Flash and also internal link to the MPEG SDRAM inteface. At start-up,the SDRAM bus is checked

Table 5-6 Memory check

Interconnection 6 PapChksFl Checksum FLASH 16 CompSdramWrR SDRAM Write Read

CompSdramWrR checks the complete SDRAM for failures inside the IC.The BasicInterconSDRAM check is done by writing & reading some well chosen patterns to all address and data interconnections of the SDRAM. The PapChksFI calculate and verify checksum of the FLASH. This includes the binary file checksum and the four modules.

5.4 General I/O Port & Peripherals Check

5.4.1 I2C Bus / EEprom Check

To access the EEprom, the I2C bus is used. So by writing and reading to the EEprom the chip and the bus is checked. With next commands a certain byte is written to the EEprom. The original information will always be written back into the EEprom.

5.4.2 Audio Clock Switch Check

The internally generated Audio clock can be set to either 44.1 kHz (CD_DA), 48 kHz (DVD) or 96 kHZ (DVD). To check the different mode, use the following commands and measure the waveform as correct operation cannot be detected by the Diagnostic Software.

An aditional part of the video-path is the scart functionswitching test. The scart function-switching pin has three levels which depend on the level of the output ports SCART0 and SCART1. These latter two signals are driven by the output pins PIO3.6 and PIO3.7 of the STi55xx. Check the level of SCART0 and SCART1 with the following commands:
