6.1 DEALER SCRIPT
6.1.1 Purpose of Dealer Script
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 a "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.

DIAGNOSTIC SOFTWARE : SCRIPT INTERFACES
6.2 PLAYER SCRIPT
6.2.1 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 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 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.
6.2.2 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.
6.2.3 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.
2. The loop test will perform the same nuclei as the dealer test, but it will loop through the list of nuclei indefinitely.

6.3 INTERACTIVE TESTS
6.3.1 DISPLAY PCB
DISPLAY TEST
The display test is performed by nucleus DispDisplay. By putting a series of test patterns on the local display, the local display is tested. To step through all different patterns, the user must either press PLAY (pattern is ok) or PAUSE (pattern was incorrect) to proceed to the next pattern. The display of patterns is continued in a cyclic manner until the user presses NEXT. If the user presses NEXT before all display patterns are tested, the DispDisplay nucleus will return TRUE (display test successful).
LED TEST
The LED(s) on the DVD player is (are) tested by nucleus DispLed. The user must check if the LED(s) is (are) lighted; if it is, press PLAY, if it is not, press PAUSE. By pressing NEXT the script will proceed to the next test. If the user presses NEXT before PLAY or PAUSE, the DispLed nucleus will return TRUE (LED test successful).

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 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:

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 the PREVIOUS button, the colour bar with the first setting becomes visual again. By pressing PLAY the user confirms the test, pressing PAUSE will indicate that something went wrong. The test can be left by pressing the NEXT key for more than one second; if the user presses NEXT without pressing PLAY or PAUSE first, the result of this test will be TRUE (colour set-up ok).
6.3.3 BASIC ENGINE
VERSION NUMBER
In the basic engine tests, the version number of the Basic Engine will be shown first, as the following example:
Figure 6-20
By pressing the NEXT key, the Basic Engine tests are started.
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 6-17
By pressing PLAY the user confirms the test, pressing PAUSE will indicate that something went wrong. Pressing NEXT will proceed to the next; if the user presses NEXT without pressing PLAY or PAUSE first, the result of this test will be TRUE (sound ok).
Colour set-up test
The colour set-up test is performed by putting the internally generated colour bar in diffferent settings on the TV screen. The first colour bar will be displayed in setting 1. The display will show the following message:

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. Example:
FAU LTY MODULE(S)
The number after the hyphen indicates the number of times the loop test has been performed; the 4 digits at the right side of the display show the last error that was found when running the loop test: the leftmost two digits of this code indicate which nucleus resulted in a fault; the rightmost two digits refer to the faultcode within that nucleus.

7.1 Replacing DVD module
The DVD module(Basic Engine and the mono board) has to be exchanged completely in case of failure. A new module for Xemix can be ordered with codenumber 291-90350.969 for Region Code 4 (Australia), 291-90350.970 for Region Code 5 (Russia), and 291-90350.968 for all European countries Region Code 2. A new module for Auro can be ordered with codenumber 291-90350.988 for Region Code 4 (Australia), 291-90350.989 for Region Code 5 (Russia),and 291-90350.987 for all European countries Region Code 2. Return the defective unit complete assembled in original package to Loewe Consumer Service in Kronach.
7.2 Reprogramming of new mono boards.
Caution
This information is confidential and may not be distributed. Only a qualified service person should
reprogram the mono board.
After replacement of the mono board, all the customer settings and also the region code will be lost. Reprogramming of the mono board will put the player back in the state in which it has left the factory, i.e. with the default settings and the allowed region code.
Reprogramming is limited to 25 times. When the counter reaches 25, reprogramming is not possible anymore Reprogramming will be done by way of the remote control. Put the player in stop mode, no disc loaded. Press the following keys on the remote control:

8.1 Display board
8.1.1 Introduction
These test instructions are written for all versions of the display PCB 396-90348.973. The contents of the PCB can be split up into next blocks:
V filament
V filament Buffer
I2C
Supply:
+5Vstby +12V
-40V
8.1.2 Functionality description:
The essential component of the display PCB is the uP (slave). This slave works on an 8MHz resonator and has a reset circuit that is triggered by the +5Vstby. After the reset pulse, the standby control line will release the reset of the host uP. This host uP will then initialise the slave. In addition, when going to stand-by, the slave will put the host uP in reset. When the slave receives the right IR or key code to leave the standby mode, the reset of the host uP will be released. Other slave functions are:
Square signal generator to generate the filament voltage, which is required for an AC FTD.
Generates the grid and segment scanning for the FTD.
Generates a scanning grid for the keys (separated from display scanning).
Has inputs for RC (RC5 and RC6) and P50 (P50 controller is built in).
8.1.3 General
Oscilloscope measurements have been carried out using a Philips PM3392A.
Impedance of measuring-equipment should be > 1M(.
To do correct measurements we recommend to use supply 396-90350.937, which is used in all "second generation B" DVD-players. Make sure that the main 3.3V has a 0.7A load.

8.1.8 Karaoke interface
The karaoke interface (4 lines) is a single direction communication. This means that it consists of four uP output lines. The interface can be checked by setting or resetting these output-ports via the I2C bus. Send next command via the I2C bus: Address : 0x70 Command byte : 0x24 Data byte : xxxxabcd Wherea : a = Karaoke reset.
: b = Karaoke data. : c = Karaoke clock. : d = Karaoke strobe.
8.1.9 P50 interface
P50 is a bi-directional serial interface, which is used for communication between video equipment. For European sets, this communication goes via pin 10 of the scart-bus. In other regions, it can be a cinch bus at the back of the set.
1. Keep the uP in reset by short-circuiting emitter and collector of transistor 7108, via resistor 3100 and 3104 transistor 7101 is switched on.
2. Check the voltage at the P50 output connector 1118-5: < 200mV.
When the reset is released the uP output-pin becomes low and transistor 7101 is switched off.
