5.5 Error Codes
5.5.1 Introduction
Error codes are required to indicate failures in the TV set. In
principle a unique error code is available for every:
•
Activated (SW) protection.
• Failing I
2
C device.
• General I
2
C error.
The last five errors, stored in the NVM, are shown in the
Service menu’s. This is called the error buffer.
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, it is displayed at the left side and all other errors shift one
position to the right.
An error will be added to the buffer if this error differs from any
error in the buffer. The last found error is displayed on the left.
An error with a designated error code never leads to a
deadlock situation. It must always be diagnosable (e.g. error
buffer via OSD or blinking LED).
In case a failure identified by an error code automatically
results in other error codes (cause and effect), only the error
code of the MAIN failure is displayed.
5.5.2 How to Read the Error Buffer
You can read the error buffer in three ways:
•
On screen via the SAM/CSM (if you have a picture).
Example:
–
ERROR: 000 000 000 000 000: No errors detected
– ERROR: 013 000 000 000 000: Error code 13 is the
last and only detected error
– ERROR: 034 013 000 000 000: Error code 13 was
detected first and error code 34 is the last detected
(newest) error
• Via the blinking LED procedure (when you have no
picture). See paragraph
5.6 The Blinking LED Procedure .
5.5.3 Error codes
In this chassis only “layer 2” error codes are available and point
to problems on the SSB. They are triggered by LED blinking
when CSM is activated. Only the following layer 2 errors are
defined:

5.5.4 How to Clear the Error Buffer
The error code buffer is cleared in the following cases:
•
By using the CLEAR command in the SAM menu
• By using the CLEAR command in the Factory mode:
• By using the following key sequence on the remote control
transmitter: “062599” directly followed by the OK button.
• If the contents of the error buffer have not changed for 50
hours, the error buffer resets automatically.
Note: If you exit SAM by disconnecting the mains from the
television set, the error buffer is not reset.
