5.5.2
How to Read the Error Buffer
Use one of the following methods:
•
On screen via the SAM (only when a picture is visible).
E.g.:
–
00 00 00 00 00: No errors detected
–
23 00 00 00 00: Error code 23 is the last and only
detected error.
–
37 23 00 00 00: Error code 23 was first detected and
error code 37 is the last detected error.
–
Note that no protection errors can be logged in the
error buffer.
•
Via the blinking LED procedure. See section
Clear the Error
Buffer.
•
Via ComPair.
5.5.3
How to Clear the Error Buffer
Use one of the following methods:
•
By activation of the "RESET ERROR BUFFER" command
in the SAM menu.
•
With a normal RC, key in sequence "MUTE" followed by
"062599" and "OK".
•
If the content of the error buffer has not changed for 50+
hours, it resets automatically.

In case of non-intermittent faults, clear the error buffer before
starting to repair (before clearing the buffer, write down the

content, as this history can give significant information). This to
ensure that old error codes are no longer present.
If possible, check the entire contents of the error buffer. In
some situations, an error code is only the result of another error
code and not the actual cause (e.g. a fault in the protection
detection circuitry can also lead to a protection).
There are several mechanisms of error detection:
•
Via error bits in the status registers of ICs.
•
Via polling on I/O pins going to the stand-by processor.
•
Via sensing of analogue values on the stand-by processor
or the PNX8543.
•
Via a "not acknowledge" of an I
Take notice that some errors need several minutes before they
start blinking or before they will be logged. So in case of
problems wait 2 minutes from start-up onwards, and then
check if the front LED is blinking or if an error is logged.
