Service Test Programme

The Service Test Programme is divided into 3 different parts:
– Automatic System Test
– Manual System Test
– PC System Test
The basis of these System Tests are the Service Test Levels, which are
carried out automatically with the respective test or can be called up
manually.
1. Automatic System Test
With the Automatic System Test the hardware of the DVD-Player can
be checked without further equipment.
During the Automatic System Test the Service Test Levels, which are
listed in the table, are called and executed. If the DVD-Player is faulty,
"Error" is shown on the display and the Service Test Levels have to be
executed with the Manual System Test or the PC System Test.
Remark: With the Automatic System Test the A/V-MUX-board is not
tested.

2. Manual System Test
The Manual System Test is a possibility to check which of the modules
(Keyboard Control Unit, Digital Board or Basic Engine) is faulty. In
addition to that, it is possible to check all ERRORS by reading the
ERROR log and the ERROR bits, including the ERRORS which have
appeared in the normal use of the DVD-Player. At the end of the
Manual System Test a Loop Test is started (the Service Test Levels of
the Automatic System Test are running in an endless loop).
For this test the DVD-Player has to be connected to a TV Set (PAL or
Multisystem), to control the results of the Service Test Levels.
To check the results of some Service Test Levels, the System Test
requires interactive actions from the user (e.g. confirmation of a
testpicture or a testsound). For some levels (e.g. levels for testing the
basic engine functions) the DVD-Player has to be opened to control the
function of the moveable components.
The test only checks functions, which can be checked by the Service
Test Software.

Display Test
Service Test Level: DispDisplay
By showing 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
cyclically manner until the user presses NEXT.
Note that a different sample pattern is used here to show all different
display patterns. All other pattern in this document are simplified for
essentials.
If the user presses NEXT before all display patterns are tested, it will
cause an error in the overall result of the System Test.
