4. LOOP TEST
At the start of the loop test, the display will show the result
of the interactive player test:
Figure 25
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 Mono
PCB Display
PCB
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
Figure 26
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
MODULE(S) LOOP
COUNTER NUCLEUS ERROR
Figure 27
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.
