that this test will not contribute to the test result of the
Basic Engine. Pressing PLAY 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:
Fig. 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 key.

5.9 Error Log

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 :
Fig. 30
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 "00"
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 on the local keyboard, the user can
proceed to the next test.

5.10 Error Bits

Reading the error bits is done by nucleus LogReadBits.
The display during the errorbits readout looks as follows:
Fig. 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 errorcodes. If the display
only shows "EB-0", no error bits were set. By pressing
PLAY 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:
Fig. 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 Indication for each module
Value
Basic Engine
000 ok
001 ok
010 ok
011 ok
100 faulty
101 faulty
110 faulty
111 faulty
Fig. 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 Fig. 34 until the user
presses the PLAY key and then it will continue to the next
loop.
Example:
Fig. 34
The 2-digit number (23) on the right of Fig. 32 indicates the
number of times the loop test has been performed.
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. For further
explanation of this error code, refer to chapter 8 (Nuclei
Error Codes).
