HANDLING CHIP COMPONENTS

1-6

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.

Tous les IC et beaucoup d’autres semi-conducteurs sont sensibles aux décharges statiques (ESD). Leur longévité pourrait être considérablement écourtée par le fait qu’aucune précaution n’est prise à 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 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 kan die Lebensdauer drastisch reduzieren. Veranlassen Sie, dass Sie im Reparaturfall über ein Pulsarmband mit Widerstand verbunden sind mit dem gleichen Potential wie die Masse des Gerätes. Bauteile und Hilfsmittel auch auf dieses gleiche Potential halten.

ESD PROTECTION EQUIPMENT:

Alle IC’s en vele andere halfgeleiders zijn gevoelig voor electrostatische 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.

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 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.

2. Product Overview

The purpose of the DVD Diagnostic Software is to support the user (factory and service) in diagnosing the DVD player. The context of the diagnostic software consists of:

- Service PC, a personal computer with a terminal emulation program that emulates a simple ASCII terminal.

The Service PC is connected to the RS232 port of the DVD player and is used for Level 2 / Second Line diagnostic mode. The Service PC is operated by a service personnel or repairman.

- Local Keyboard, input device of the DVD player hardware, used during power-on and during the execution of

the Player Test Script.

- Test Pin, input device of the DVD player hardware, used during power-on.

- Local Display, output devices of the DVD player hardware, used by the Player Test Script and Dealer Test

Script to output messages and test results.

- Control PC, a computer system in the factory connected to the RS232 port of the DVD player, used during

Level 1 diagnostic mode to communicate with the Diagnostic Software (bi-directional).

- DVD Player Hardware, all the DVD player hardware which is subject to the Diagnostic Software.

The DVD has only one single RS232 port, implying that all interfaces using this port are mutually exclusive. The Full Diagnostic Software (FDS) is aimed to support service and repair and can present menus and receive commands via a Service PC.

The Diagnostic Software contains a large number of tiny Diagnostic Nuclei. Each nucleus contains an atomic and software independent diagnostic test, testing a functional part of the DVD player hardware on component level. Each Diagnostic Nucleus works directly on the DVD player hardware, no drivers will be used. Each Diagnostic Nucleus returns a Result indicating if and which error was detected (e.g. faulty SDRAM chip).

It is possible to combine these diagnostic nuclei in a Script to create a high level test like a player test, a script can be as simple as a sequence of executed Diagnostic Nuclei. The Diagnostic Software contains standard scripts for dealer and player test. Each script returns a Result indicating if and which error was detected (e.g. faulty module).

3-2

During power-on the Selector (part of the DVD boot sequence) will check the presence of certain triggers (signal on Test Pin, key combinations on local keyboard). Via the Selector the appropriate diagnostic mode will be activated:

Power-on condition Activate diagnostic mode: Short Description

Name used Name used in Factory in Service

OPEN & PLAY key (Dealer Script) Dealer test Fully automatic stand-alone test without any user pressed intervention resulting in one overall result: passed or

not passed.

No SDRAM tests are performed prior to DSW startup. OPEN & STOP key Level 3 or First Line Automatic test sequence with user intervention and pressed Player test use of screen/audio test device (i.e. a television set).

(Player Script) The result will be an indication of which board is

faulty.

No SDRAM tests are performed prior to DSW startup. Test pin active & ‘C’ Level 1 or - Externally (Control PC) controlled test sequence via character received Module test a simple command line interface. Each command from RS232 Port in production activates one Diagnostic Nucleus.

line SDRAM tests are performed prior to DSW startup. Test pin active & ‘M’ Level 2 or Second Line Externally (Service PC) controlled test sequence via character received Module test a simple menu driven interface. Each menu selection from RS232 Port for repair activates a Diagnostic Nucleus or a Standard Script.

SDRAM tests are performed prior to DSW startup.

Note: Some players do not have a power-on key, in such cases, the player must be powered-on by connecting the power-cable.

The Selector, Command Handler and Menu Handler are the heart of the Diagnostic Software and will be referenced as the Diagnostic Engine in the context of this document. They form a framework in which Diagnostic Nuclei and standard Scripts can be added via a well-defined software interface. The actual contents of the Menu Handler are part of the FDS.

3. Product Functions

Dealer diagnostics (For I2C Master Modules only)

The dealer diagnostic mode can be activated by pushing the script activation keys during power-on. The script activation keys vary depending on the model used. This test consists of running a predefined script (Dealer Test Script). The script controls the execution of a number of diagnostic tests. No external input is required during the execution of the script. During the execution a progress indicator will be displayed on the local display. At the end of the script one message is returned indicating if a failure in the DVD player is detected or not. The message will be displayed on the local display. No external test equipment is required.

DVD Project/Model Dealer Script mode activation key DVP900 – All series Press and hold OPEN and PLAY key

First Line & Level 3 diagnostics (For I2C Master Modules only)

The First Line & Level 3 diagnostic mode can be activated by pushing the script activation keys during power-on. The script activation keys vary depending on the model used. This test consists of running a predefined script (Player Test Script). The script controls the execution of a number of diagnostic nuclei. The first group of Diagnostic Nuclei in this script will check the local display and the local keyboard and will output the result on the local display before it continues with the remaining Diagnostic Nuclei of the script. The Diagnostic Nuclei for the readout of the error log and the Basic Engine will also be part of the predefined script. During execution of the script input from the local keyboard is required for confirmation of

3-3

certain steps. At the end of the script a message is returned indicating if a failure in one of the modules (Basic Engine, Digital PWB or Display PWB) is detected or not. The message will be displayed on the local display. The test will be done with a closed player and requires equipment for testing audio and video (e.g. a television set).

DVD Project/Model Player Script mode activation key DVP900– All series Press and hold OPEN and STOP key

Level 1 diagnostics

The Level 1 diagnostic mode can be activated by making the test pin active (pull to ‘L’) during power-on and subsequently, sending a ‘C’ character to the RS232 port. The execution of Diagnostic Nuclei is under external control via a simple command line interface. There is no standard Level 1 Script embedded in the Diagnostic software. Each command activates one Diagnostic Nucleus. In case a Diagnostic Nucleus detects a failure it will try to give an indication via Result which component(s) or connection(s) is (are) failing. Result consists of an error number and an error string. These will be sent to the Control PC. The error string contains the textual equivalent of the error number extended with additional detailed error information. The required external test equipment will be part of the Control PC.

Second Line & Level 2 diagnostics

The Second Line & Level 2 diagnostic mode will be activated by making the test pin active during power-on and sending a ‘M’ character to the RS232 port. The execution of Diagnostic Nuclei is under external control via the terminal program on the Service PC with a simple menu driven interface. In case a Diagnostic Nucleus detects a failure it will try to give an indication via Result of which component(s) or connection(s) is(are) failing. Result consists of an error number and an error string. These will be sent to the service PC. The error string contains the textual equivalent of the error number extended with additional detailed error information. The required external test equipment will be part of the standard repair suite.

4. Functional Requirements

Diagnostic Engine

The diagnostic Engine consists of the following objects:

- Selector (partly implemented in the DVD boot sequence)

- Command Handler

- Menu Handler The actual contents of the Menu Handler are part of the FDS.

Scripts

Each script controls the execution of Diagnostic Nuclei. There is no direct interaction from the script with the hardware. A script can be a sequence of Diagnostic Nuclei and can also contain branches and loops. Results of the execution of a Script are given back to the user. The Scripts will be embedded in the ROM of the DVD player and will be written in C-code as part of sources of the Diagnostic Software (there is no script interpreter).

The following script objects are defined for the Basic Diagnostic Software:

- Dealer Test Script

- Player Test Script

Diagnostic Nuclei

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 color 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’.

3-4

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.

Since this document caters to more than one SD module, and not all modules support the same set of test nuclei, a note is placed in the remarks of each test to indicate whether this applies to a specific module or not. Otherwise it is assumed that the test is supported by all platforms.

5. Description of Diagnostic Engine

Selector

During initialization of the Diagnostic Software the Selector will first execute the required Basic Diagnostic Nuclei (nuclei of which the names start with the word “Basic”) to ensure correct operation. In case one of the basic diagnostics fails an error code and message will be communicated to the outside world via the RS232. In case all basic diagnostics are passed successfully, the selector will activate the appropriate diagnostic mode.

3-7

Command Handler

The Command Handler handles all commands from the Control PC. Commands will be received as ASCII strings via the RS232 port. All commands received is interpreted by the Command Handler and only correct commands result in the execution of the matching Diagnostic Nucleus. Illegal commands result in an error message to the Control PC.

Menu Handler

The Menu Handler (part of the Full Diagnostic Software) handles all menus and selections to and from the Service PC. The interface consists of simple text menus with sub-menus. A menu selection results in the execution of the matching Diagnostic Nucleus. Only valid menu selections will be accepted.

6. Description of Script Objects

Dealer test (for I2C Master Modules Only)

The Dealer Test Script object performs the Dealer test by executing a few Diagnostic Nucleus which do not need any user intervention and are meaningful on a stand alone DVD player. During the execution of the Dealer test a progress indicator will be displayed on the local display.

In general the Diagnostic Nuclei with a large test scope (i.e. testing many components at once) will be executed first.

When a Diagnostic Nucleus detects a fault a message indicating that the test is not passed will be displayed on the local display [ ERROR ] and the Dealer test will terminate. If all Diagnostic Nuclei are passed successfully a message indicating that the test is passed [ PASS ] will be displayed on the local display and the Dealer test will terminate. The only way to continue after termination is via a power down of the DVD player.

Player test (for I2C Master Modules Only)

The Player Test Script object performs the Player test by executing all available Diagnostic nuclei which are meaningful on a DVD player which is connected to audio/video test equipment (e.g. a television set). Some Diagnostic Nuclei require user intervention.

The first phase will check the following modules:

- Display PWB (communication, display, backlight, LEDs, keyboard, RC, P50)

- Basic Engine (communication, mechanical)

- Digital PWB (all components)

For each module all the available Diagnostic Nuclei which are meaningful for that module will be executed. Some Diagnostic Nuclei require user intervention. After all tests have been executed an indication will be given on the local display which module is most likely to be faulty. Also, the error code of the last detected error will be displayed. To continue, push the PLAY key on the local keyboard, the second phase will be entered automatically. The test of the module Display PWB consists of the Diagnostic Nuclei PapI2cDisp, DispDisplay, DispLCDisplay, DispLCDBkLight , DispLed, DispKeyb and DispRc and can be aborted at any moment by switching the power off.

The second phase is the read out of the error log and error bits from the NVRAM. Only a part of the information will be displayed on the local display at the time. With the keys: STOP key and OPEN/CLOSE (EJECT) key, it will be possible to walk through the whole error log and bits in a controlled way. The loop phase can be entered by pushing the PLAY key on the local keyboard.

The loop phase will check the following modules:

- Display PWB (communication)

- Basic Engine (communication)

- Digital PWB (all components)

For each module all the available Diagnostic Nuclei which are meaningful for that module will be executed. None of the Diagnostic Nuclei require any user intervention. After all tests have been executed an indication will be given on the local display which module is most likely to be faulty. Also, the error code of the last detected error will be displayed. A loop counter on the local display will be incremented and the loop phase will start all over again.

7. Description of Diagnostic Nucleus Objects

BasicSpAcc

This is a Basic Diagnostic Nucleus required for correct operation of the Diagnostic Software. Checks and initializes RS232 port and outputs a message that the Diagnostic software has been started.

CompProcInfo

Reads and display processor specific information. This platform specific function allows the user to read certain registers in the chip at runtime that would be helpful in getting info on the current chip used. For ZiVA5, the LatchedOn-Reset register contents and the Chip Revision register contents are read and displayed.

PapChksFlash

Calculates and verifies the checksum of the backend FLASH or ROM. This includes the entire binary ROM image checksum.

PapUclkAclkCdda, PapUclkAclkDvd, PapUclkAclkDvd96 (for SD5.2 only)

Diagnostic Nucleus PapUclkAclkCdda switches clock A_CLK from the microclock to 16.93 MHz(CD_DA). Diagnostic Nucleus PapUclkAclkDvd switches clock A_CLK from the microclock to 18.43 MHz(DVD). Diagnostic Nucleus PapUclkAclkDvd96 switches clock A_CLK from the microclock to 36.86 MHz(DVD). Correct operation cannot be detected by the Diagnostic Software but must be checked with external equipment (e.g. a frequency counter).

Note:

This nucleus will only work if the external clock is available on board.

PapSgsAclkCdda, PapSgsAclkDvd, PapSgsAclkDvd96

Diagnostic Nucleus PapSgsAclkCdda switches the PCM clock to 16.93MHz(CD_DA). Diagnostic Nucleus PapSgsAclkDvd switches the PCM clock to 18.43 MHz(DVD). Diagnostic Nucleus PapSgsAclkDvd96 switches the PCM clock to 36.86 MHz(DVD).

Correct operation cannot be detected by the Diagnostic Software but must be checked with external equipment (e.g. a frequency counter).

PapFlashWrAcc

Reads out the Flash ROM’s Chip Identification Number. This nucleus tests the write access by writing a defined sequence of data to the FLASH chip, to be able to read the FLASH ID number.

PapI2cNvram

Checks the I2C interface with the NVRAM by reading from an arbitrary address.

PapI2cDisp (for SD5.2 only)

Checks the I2C or SIO bus interface with the slave processor on the display PWB with the echo command.

PapUDEEcho (SD5.2) / PapAtapiEcho (SD5.12/SD5.31)

Checks the UDE / ATAPI interface to the basic engine with an ‘echo’ command. This tests the hardware communications interface between the loader and the backend processor.

PapUDEPass (for SD5.2 only)

Switches the RS232 port and the UDE port in pass-through mode. The only way to exit this nucleus is via a power off of the DVD player.

PapNvramWrR

Non destructive pattern test (checker board) of all locations in the NVRAM. This Nucleus can detect stuck at faults and permanent coupling errors in the NVRAM chip.

VidPortOutAA, VidPortOut55 (for SD5.2 only)

Writes the value 0xAA to the Digital Video Interface port of the ZiVa5 ITU-656 ports. Writes the value 0x55 to the Digital Video Interface port of the ZiVa5 ITU-656 ports.
