TRAY TEST
As a last action for the Basic Engine tests, the tray test is
repeated. The local display will look as follows:
Figure 5-31
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
PLAY and PAUSE key. The tray will be closed (by the
software, if it is open) before proceeding to the next test when
the user presses the NEXT key.

ERROR LOG (see table on page 30)
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 5-32
By pressing PLAY or PAUSE the user can move forward or
backward (respectively) through the logged error codes. The
highlighted number indicates which errorcode is currently on
display (in the example above, errorcode 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 errorcode with the lowest highlighted number is
the most recent. By pressing NEXT on the local keyboard,
the user can proceed to the next test.
5.5.10 ERROR BITS (see table on page 30)
Reading the error bits is done by nucleus LogReadBits. The
display during the errorbits readout looks as follows:
Figure 5-33
Only the set errorbits will be shown by their (decimal)
number. Refer to the appropriate documentation 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.

LOOP TEST (see table below)
At the start of the loop test, the display will show the result of
the interactive player test:

Figure 5-34
The left side of the display contains a 3-digit code, which can
have a value between 000 and 111. These values are to be
interpreted as follows:

Figure 5-35
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:
FAULTY
LOOP
MODULE(S)
COUNTER
Figure 5-36
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. For further
explanation of this error code, see list of error codes below.
