5、资料库 Technical specificationsGB 2DVD612 /XX11. 1.Technical specifications English Specification PLAYBACK SYSTEM DVD-Video Video CD no other equipment is needed to perform a number of hardware tests to check if the DVD player is faulty. The diagnosis is simply a error or pass message; no indication is
6、 given of faulty hardware modules. Only tests within the scope of the diagnostic software will be executed hence only faults within this scope can be detected. 5.1.2Contents of Dealer Script The dealer script executes all diagnostic nuclei that do not need any user interaction and are meaningful on
7、a standalone DVD player. The nuclei called in the dealer script are the following (the number after each nucleus name corresponds with the number being on the local display when the nucleus is executed during the dealer script): Figure 5-1 Figure 5-2 CL06532096_001.eps 050700 NucleusDescription Vide

Diagnostic software descriptions and troubleshootingGB 22DVD612 /XX15. 5.2PLAYER SCRIPT 5.2.1Purpose of Player
11、Script The Player script will give the opportunity to perform a test that will determine which of the DVD players modules are faulty, to read the error log and error bits and to perform an endurance loop test. To successfully perform the tests, the DVD player must be connected to a tv set to check t
12、he output of a number of nuclei. For DVDv2b a multi-channel amplifier, a set of 6 boxes and an external video source are necessary to test. To be able to check results of certain nuclei, the player script expects some interaction of the user (i.e. to approve a test picture or a test sound). Some nuc
13、lei (e.g. nuclei that test functionality of the Basic Engine module) require that the DVD player itself is opened, to enable the user to observe moving parts and approve their movement visually. Only tests within the scope of the diagnostic software will be executed hence only faults within this sco
14、pe can be detected. 5.2.2Contents of Player Script The player script contains all nuclei that are useful on a DVD player that is connected to a tv-set and help to determine which module of the DVD player is faulty, as well as to read out the contents of the error logs. 5.2.3Structure of Player Scrip
15、t The player script consists of a set of nuclei testing the three hardware modules in the DVD player: the Display PWB, the Digital PWB and the Basic Engine. Nuclei run by the player test need some user interaction; in the next paragraph this interaction is described. The player test is done in two p
16、hases: 1.Interactive tests: this part of the player test depends strongly on user interaction and input to determine nucleus results and to progress through the full test. Reading the error log and error bits information can be useful to determine any errors that occurred recently during normal oper
17、ation of the DVD player. 2.The loop test will loop through the list of nuclei indefinitely, till the NEXT key is pressed. The list of nuclei is as follows: VideoColSetupComm VideoScartSwComm PapChksFlash PapI2cNvram CompSdramWrR PapS2bEcho PapI2cDisp For DSW version 1.6 and above. the DSW version nu

21、ST The keyboard of the DVD player is tested by nucleus DispKeyb. The user is expected to press all keys on the local keyboard once. The code of the key pressed is shown on the local display (1 hexadecimal digit) immediately followed by a (hexadecimal) number indicating how many times that key has be
22、en pressed. Example of the local display during this test: Figure 5-6 The key-codes displayed on the local display will scroll from right to left when the display gets full, the text tb- will remain on display. Figure 5-7 If any keys are detected more than once (due to hardware error), the key-code
23、is displayed twice (or more), with the second digit increased by 1. If the user does not press all keys minimally once (in any order), the DispKeys nucleus will return FALSE and cause an error in the overall result of the player script. The test will also pass if all buttons, except the microphone k
24、ey buttons, are pressed. The user can leave the keyboard test by pressing the NEXT key on the local display of the DVD player for at least one full second. The result of the keyboard test is shown on local display as follows: Figure 5-8 Or Figure 5-9 Pressing NEXT on the local keyboard again will pr
