Error Codes
5.5.1
Introduction
The error code buffer contains all errors detected since the last
time the buffer was erased. The buffer is written from left to
right. When an error occurs that is not yet in the error code
buffer, the error code will appear at the left side and all other
errors shift one position to the right.
5.5.2
How to Read the Error Buffer
Use one of the following methods:
•
On screen via the SAM (only possible when you have a
picture). Examples:
–
ERR: 0 0 0 0 0 0 0 : No errors detected.
–
ERR: 6 0 0 0 0 0 0 : Error code 6 is the last and only
detected error.
–
ERR: 9 6 0 0 0 0 0 : Error code 6 was first detected and
error code 9 is the last detected (newest) error.
•
Via the "blinking LED" procedure, if no picture is available.
See explanation of "The blinking LED procedure" below.
5.5.3
How to Clear the Error Buffer
The error code buffer will be cleared in the following cases:
•
By activating "CLEAR ERRORS" in the SAM menu.
•
By exiting SDM or SAM with the "Standby" command on
the remote control.
•
Upon automatic reset, when the content has not changed
for 50 consecutive hours.
Note: By leaving SDM or SAM via the Mains switch, the error
buffer will not be reset.
5.5.4
Error Codes
In case of non-intermittent faults, clear the error buffer before
starting the repair. This to ensure that "old" error codes are no
longer present. Before clearing the buffer, write down the
content, as the history can give you valuable information. If
possible, check the entire content 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).
Table 5-1 Error Code Table
Note: Error codes 1,2, 3, and 4 are protection codes, and in this
case, the supplies of some circuits will be switched "off". Also,
in protection, the LED will blink the number of times equivalent
to the most recent error code.
