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 :
REPEAT
V C D
SHUFFLE PAUSE SCAN A B - CHAPTER TITLE TRACK
TOTAL TRACK TITLE
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 + - - - - - - - - - - - - - -
F T S
CHAPTER REM TRACK TIME
D V D
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:
REPEAT

SHUFFLE PAUSE SCAN A B - CHAPTER TITLE TRACK

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
At the start of the loop test, the display will show the result of the
interactive player test:

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
Value
Indication for each module
Basic
Engine
Digital
PCB
Keyboard
Control Unit
000 ok ok ok
001 ok ok faulty
010 ok faulty ok
011 ok faulty faulty
100 faulty ok ok
101 faulty ok faulty
110 faulty faulty ok
111 faulty faulty faulty
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:
REPEAT

SHUFFLE PAUSE SCAN A B - CHAPTER TITLE TRACK
TOTAL TRACK TITLE

module loops error code
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.
