Diagnostic Software Descriptions and Troubleshooting
The user can switch between the three different types of
groove settings by pressing PLAY (forward to next nucleus 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 Basic Engine. Pressing NEXT
proceeds to the next test, after the disc motor has been shut off
with a call to nucleus BeDiscMotorOff.
5.5.8
Tray Test
As a last action for the Basic Engine tests, the tray test is
repeated. The local display will look as follows:
Figure 5-29
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
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.
5.5.9
Error Log (See Table on Page 28)
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 5-30
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
Reading the error bits is done by nucleus LogReadBits. The
display during the errorbits readout looks as follows:
Figure 5-31
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 5-32
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:
Displayed
Indication for each module
Value
Basic Engine
000
ok
001

010

011

100

101

110

111

Figure 5-33
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.
Example:
FAULTY
LOOP
MODULE(S)
COUNTER
Figure 5-34
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 indicates which
nucleus resulted in a fault; the rightmost two digits refer to the
faultcode within that nucleus. For further explanation of this
error code, refer to chapter 5.8 Nuclei Error Codes.
Errorlog
Explanation:
The application errors will be logged in the NVRAM. The
maximum number of error bytes that will be visible is 16. The
first word (4 digits) of the byte is the component identification;
the last word is the error code.
The diagnostics software will present a combination of this
component identification plus an error code on the local display
(and on the attached terminal). The last reported error is shown
as < 00000000, the oldest visible error as 00000000> and the
errors in between as < 00000000 >.
