Product Overview The purpose of the DVD Diagnostic Software is to support
12、 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
13、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 po
14、wer-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 communicat
15、e 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
16、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 compone
17、nt 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 tes
18、t 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). 3-1 During power-on the Selector (p
19、art 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 acti- vated: Power-on conditionActivate diagnostic mode:Short Description Name usedName used in Factoryin Servi

Note: Some players do not have a power-on key, in such cases, the player must be powered-on by connecting the power-cable.
24、 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 actu
25、al 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 consist
26、s 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 m
27、essage is returned indicat- ing if a failure in the DVD player is detected or not. The message will be displayed on the local display. No exter- nal test equipment is required.

28、iagnostics (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 co
29、ntrols 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
30、 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 3-2 certain steps. At the end of the script a message is returned indicating if a failure in one of the modu
31、les (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/ModelPlayer Script mode activation key DVP900 All
32、seriesPress 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 comma
33、nd 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
34、 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 diagnost
35、ics 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 c
36、ase 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
37、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) -C
38、ommand 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 a
39、nd 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 Di
40、agnostic 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 co
41、lor 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,
42、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
43、 Engine is operational it is possible to do a full RAM diagnostic. All basic diagnostic nuclei start with prefix Basic. 3-3 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
44、 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 platfo
45、rms.
