The dealer script can give a diagnosis on a standalone DVD player, no other equipment is needed to perform a number of hardware tests to check if the DVD player is faulty. The diagnosis is simply an "error" or "pass" message. No indication is 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.

DVD-C740

/DV-C6660

2.1 Purpose of Player Script

The Player script will give the opportunity to perform a test that will determine which of the DVD player's 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 the output of a number of nuclei. For DVDv2b a multi-channel amplifier, a set of 6 speakers 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 nuclei (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 scope can be detected.

2.2 Contents 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.

2.3 Structure of Player Script

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 phases:

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 operation of the DVD player.

The loop test: this part of the player test will loop through the list of nuclei indefinitely, untill the player is reset. The list of nuclei is as follows:

PapChksFlash PapI2cNvram CompSdramWrR PapS2bEcho PapI2cDisp

At the beginning of the tests, the DSW version number will be indicated on the local display of the DVD. The display will look like the following:

3.1 Display Test

The display test is performed by nucleus DispDis play. By putting as erie of test patterns on the local display, the local display is tested. To step through all different patterns, the user must either press OPEN/CLOSE (pattern is ok) or STOP (pattern was incorrect) to proceed to the next pattern. The display of patterns is continued in a cyclic manner, shown in Fig. 6, until the user presses PLAY/PAUSE. If the user presses PLAY/PAUSE before all display patterns are tested, the DispDisplay nucleus will return FALSE (display test unsuccessful).

If any keys are detected more than once (due to hardware error), the key-code 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 user can leave the keyboard test by pressing the PLAY/PAUSE key on the local keyboard of the DVD player for at least one full second. The result of the keyboard test is shown on local display as follows:

3.3 Keyboard Test

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 been pressed. Example of the local display during this test:

Pressing PLAY/PAUSE on the local keyboard again will proceed to the next text.

3.4 Remote Control Test

The remote control of the DVD player is tested by nucleus DispRc. The user must press any key on the remote control just once. The codes of the key pressed will be shown on the local display in hexadecimal format. Example:

/DV-C6660

DVD-C740

The key-codes displayed on the local display will scroll from right to left when the display gets full, the text "K" will remain on display.

Figure 11

In this example 23 is the hexidecimal code of the pressed RC key. The user can leave the remote-control test by pressing PLAY/PAUSE on the local keyboard of the DVD player. The remote control test is successful if a code was received before the user pressed the PLAY/PAUSE key.

DVD-C740/DV-C6660

Pressing the PLAY/PAUSE key, before pressing a key on the remote control, gives an error in the remote control test (note that the remote control test will also fail if a key on the remote control was pressed but no code was received). The remote control test does not check upon the contents of the received code, that is it will not be checked if the received code matches the key pressed. If desired, the user can manually check this code by using a code-table for the remote control key-codes.

By pressing OPEN/CLOSE the user confirms the test, pressing STOP will indicate the picture was invisible or incorrect. Pressing PLAY/PAUSE will proceed to the next test. If the user presses PLAY/PAUSE without pressing OPEN/CLOSE or STOP first, the result of this test will be TRUE (picture ok).

After the audio signal has been stopped by pressing OPEN/CLOSE, the user confirms the test. Pressing STOP will indicate that something went wrong. Pressing PLAY/PAUSE will proceed to the next. If the user presses PLAY/PAUSE without pressing OPEN/CLOSE or STOP first, the result of this test will be TRUE (sound ok).

The test can be left by pressing the PLAY/PAUSE key for more than one second.

On the TV screen a color bar (generated by nucleus VideoColDencOn) is visible and the internally generated pinknoise is audible. By pressing the PLAY/PAUSE key, the user confirms the test. Pressing the STOP key will indicate the sound was inaudible or incorrect.

Note: Only for double scart models, SCART loop-through will be simultaneously active during this test. SCART loop-through will be measured with the aid of an external video source. By pressing the PLAY/PAUSE key, the video will be switched over to the external source. This must now become visible on the TV screen (using the SCART). The local display will show the following message:

The picture test is performed by putting a predefined picture (color bar PAL) on the display (nucleus VideoColDencOn), and asking the user for confirmation. The display will show the following message:

Note: The color bar must be simultaneously available on the CVBS, YC, and RGB (or YUV) outputs available. On the SCART only the CVBS and RGB signals will be available.

The first sound test is performed by starting a pink noise sound that needs confirmation from the user (nucleus AudioPinkNoiseOn). The display will show the following message:

The internally generated color bar is still available on the CVBS and Y/C outputs. And the pinknoise-signal is still available on the cinch audio outputs. By pressing the OPEN/CLOSE button, the internally generated color bar becomes visible again.

The second sound test is performed by producing a sine sound (nucleus AudioSineOn). The signal can be stopped by pressing the STOP key. The display will show the following message:

5 Basic Engine

5.1 Version Number

In the basic engine tests, the version number of the Basic Engine will be shown first, as in the following example:

Figure 22

By pressing the PLAY/PAUSE key, the Basic Engine tests are started.

5.2 Tray Test

First, the tray is tested. The purpose of this test is also to give the user the opportunity to put a disc in the tray of the DVD player. Some tests on the Basic Engine require that a disc (e.g. DVD MPTD test disc) is present in the player. At the end of the Basic Engine tests this tray test will be repeated solely to enable the user to remove the disc in the tray. The local display will look as follows:

Figure 25

By pressing OPEN/CLOSE the user confirms that the disc motor is running. Pressing STOP indicates the disc motor does not work. Pressing PLAY/PAUSE proceeds to the next test, after a reset of the disc motor (nucleus BeDiscMotorOff). If the user presses PLAY/PAUSE before pressing OPEN/CLOSE or STOP, the result of this test will be TRUE (disc motor is running).

5.5 Focus Test (Visual Test)

The fourth Basic Engine test tests the focussing. First focussing is turned on by calling nucleus BeFocusOn. The display will look as follows:

5.3 Sledge Test (Visual Test)

DVD-C740

/DV-C6660

Figure 23

By pressing OPEN/CLOSE the user can toggle the position of the tray. Note that this test will not contribute to the test result of the Basic Engine. Pressing PLAY/PAUSE will proceed to the next test. At this point, the tray will be closed automatically by the software if it was open.

The second Basic Engine test tests the sledge. The user can move the sledge as many times as desired by using OPEN/ CLOSE (nucleus BeSledgeOut) and STOP (nucleus BeSledgeIn). Pressing PLAY/PAUSE on the local keyboard proceeds to the next test. Note that this test will not contribute to the test result of the Basic Engine. The local display will look as follows during the sledge test:

Figure 26

By pressing OPEN/CLOSE the user confirms that the focussing was successful. Pressing STOP indicates a focussing failure. Pressing PLAY/PAUSE proceeds to the next test after a reset of the focussing (nucleus BeFocusOff). If PLAY/PAUSE is pressed before OPEN/CLOSE or STOP, the result of this test will be TRUE (focus successful).

5.6 Radial Test (Visual & Listening Test)

The fifth Basic Engine test tests the radial functionality (nucleus BeRadialOn). The local display looks as follows:

Figure 27

By pressing OPEN/CLOSE the user confirms that the radial function works. Pressing STOP indicates the function does not work. Pressing PLAY/PAUSE proceeds to the next test, after a reset of the radial (nucleus BeRadialOff). If the user presses PLAY/PAUSE before pressing OPEN/CLOSE or STOP, the result of this test will be TRUE (radial successful).

5.4 Disc Motor Test (Visual Test)

The third Basic Engine test tests the disc motor (nucleus BeDiscMotorOn). The local display looks as follows:

Figure 24

5.7 Jump Test (Listening Test)

The sixth and last Basic Engine test tests the jumping by calling nuclei BeGroovesIn, BeGroovesMid and BeGroovesO ut. During this test, the local display looks as follows:

DVD-C740/DV-C6660

Figure 28

The user can switch between the three different types of groove settings by pressing OPEN/CLOSE (forward to next nucleus in the list In-Mid-Out), or STOP (backward in the list In-Mid-Out). This is done in a cyclic manner; note that this test will not contribute to the test result of the Basic Engine. Pressing PLAY/PAUSE proceeds to the next test, after the disc motor has been shut off with a call to nucleus BeDiscMotorOff.

5.8 Tray Test

As a last action for the Basic Engine tests, the tray test is repeated. The local display will look as follows:

Figure 29

This test is meant to give the user the opportunity to remove the disc in the tray. The tray position can be toggled using the OPEN/CLOSE key. The tray will be closed (by the software, if it is open) before proceeding to the next test when the user presses the PLAY/PAUSE key.

5.9 Error Log (See Table on Next Page)

Reading the error log and error bits information can be useful to determine any errors that occurred recently during normal operation of the DVD player. Reading the error log is done by nucleus LogReadErr. The display during the errorlog readout looks as follows :

Figure 31

Only the identification number (decimal) representing set errorbits will be shown. By pressing OPEN/CLOSE or STOP, the user can move forward or backward (respectively) through the logged error codes. If the display only shows "EB-0", no error bits were set. By pressing PLAY/PAUSE the user can continue to the next test.

6 Loop Test (See Table Below)

At the start of the loop test, the local display of the DVD player will show the interactive player test result readout in the following display:

Figure 32

The left side of the display contains a 3-digit code, which can have a value between 000 and 111. These values indicate the faulty modules and are to be interpreted as follows:

Displayed Value

000 ok ok ok 001 ok ok faulty 010 ok faulty ok 011 ok faulty faulty 100 faulty ok ok 101 faulty ok faulty 110 faulty faulty ok 111 faulty faulty faulty

Note: Previous versions of the diagnostic software showed a 8-

digit error code. Due to limitations in the number of digits that can be displayed by some front panel displays, the most significant digits will not be shown. This can be done since all the error codes used by this player has set these 2 digits to ì00î

By pressing OPEN/CLOSE or STOP the user can move forward or backward (respectively) through the logged error codes. If "0000" is displayed at all positions, the error log is empty. Display of the logged errors is done in a cyclic manner. By pressing PLAY/PAUSE on the local keyboard, the user can proceed to the next test.

5.10 E rror Bits

Reading the error bits is done by nucleus LogReadBits. The display during the errorbits readout looks as follows:

Figure 33

The loop test will perform the same nuclei as the dealer test, but it will loop through the list of nuclei indefinitely. The display of the DVD player will display not only the three digits indicating correct/faulty modules and the last found error code (as mentioned, faults are detected as far as they can be within the scope of the diagnostic software), but also a loop counter indicating how many times the loop has been gone through. If an error was detected, the display will remain as in figure 34 until the user presses the PLAY/PAUSE key and then it will continue to the next loop. Example:

Figure 34

The 2-digit number (23) on the right of figure 32 indicates the number of times the loop test has been performed.

6.1 Errorlog

DVD-C740

/DV-C6660

After one loop cycle: Display the 3-digit module bits together with the last error code which occured in the loop test. The 4 digits at the right side of the display (fig. 34) show the last error that was found during the loop test. The leftmost two digits (54) of this code indicates which nucleus resulted in a fault. The rightmost two digits (03) refer to the faultcode within that nucleus.

Explanation:

The application errors will be logged in the NVRAM. The maximum number of error bytes that will be visible is 16. The first word (4 digits) of the byte is the component identification, the last word is the error code. The diagnostics software will present a combination of this component identification plus an error code on the local display (and on the attached terminal). The last reported error is shown as < 00000000, the oldest visible error as 00000000 > and the errors in between as < 00000000 >. The devices that may report errors are the serial controller (UART), the basic engine (BE), the slave processor (SLPH), the SACD Stream Manager (SSM) and the SACD Media Access (SMA). The identification of these components is as follows:

Component name Component identification

Serial controller (UART) 000A Engine (BE) 0016 Slave Processor (SLPH) 001A SACD Stream Manager

(SSM) SACD Media Access (SMA) 002E Diagnostic software (DS) Dxxx

001C

The tables in the next chapters list the error code and corresponding problem. The Explantion column has a more detailed description and the most likely reason for the error.

Some Examples:

002E0000 (SMA reported a timeout error) 0016010A (Engine could not fully close or open the tray) D0010001 (Flash checksum failed).
