Service Test Programme
Jump Test (listening test, with CD)
Service Test Level: BeGroovesIn/Mid/Out
The sixth and last Drive Mechanism test tests the jumping. During this
test, the local display looks as follows:

The user can switch between the three different types of groove
settings by pressing PLAY (forward in the list In-Mid-Out) or PAUSE
(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 Drive Mechanism.
Pressing NEXT proceeds to the next test.
Tray Test
Service Test Level: BeTrayOut/In
At the end of the Drive Mechanism tests, the tray test is repeated. The
local display will look as follows:

This test is meant to give the user the possibility to remove the disc in
the tray. The tray position can be toggled using the PLAY and PAUSE
key. The user must close the tray before proceeding to the next test
with the NEXT key.
2.2 Error Log and Error Bits
Error Log
Service Test Level: LogReadErr
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 display during the errorlog readout looks as
follows :

By pressing PLAY or PAUSE the user can move forward or backward
(respectively) through the logged error codes. The highlighted number
indicates which error code is currently on display (in the example
above, error code number 4 is displayed). If "0000" is displayed at all
positions, the error log is empty. Display of the logged errors is done
in a cyclic manner. The error code with the lowest highlighted number
is the most recent.
By pressing NEXT on the local keyboard, the user can proceed to the
next test.
See page 3-18 for ERROR LOG information.
Error Bits
Reading the error bits is done in the Level ReadBits. The display during
the error bits readout looks as follows:

Only the set errorbits will be shown by their (decimal) number. Refer
to page 3-18 for the explanation of each bit number. If the display only
shows "EB-0", no error bits were set.
By pressing NEXT the user can continue to the next test.
2.3 Loop Test

The loop test will perform the same Levels as the Automatic System
Test, but it will loop through the list of Levels. 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, earlier 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:

1 - 2 - 3 - 4 - 5 - 6 - 7 - 8
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 two
digits on the left indicate which Level resulted in a fault; the two digits
on the right refer to the error code within that Level. For further
explanation of this error code, see list of error codes.
