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

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.
5.6 The Blinking LED Procedure
5.6.1 Introduction
The software is capable of identifying different kinds of errors.
Because it is possible that more than one error can occur over
time, an error buffer is available, which is capable of storing the
last five errors that occurred. This is useful if the OSD is not
working properly.
Errors can also be displayed by the blinking LED procedure.
The method is to repeatedly let the front LED pulse with as
many pulses as the error code number, followed by a period of
1.5 seconds in which the LED is "off". Then this sequence is
repeated.

Example (1): error code 4 will result in four times the sequence
LED "on" for 0.25 seconds / LED "off" for 0.25 seconds. After
this sequence, the LED will be "off" for 1.5 seconds. Any RC
command terminates the sequence. Error code LED blinking is
in red color.
Example (2): the content of the error buffer is "12 9 6 0 0" After
entering SAM, the following occurs.
• 1 long blink of 5 seconds to start the sequence.
• 12 short blinks followed by a pause of 1.5 seconds.
• 9 short blinks followed by a pause of 1.5 seconds.
• 6 short blinks followed by a pause of 1.5 seconds.
• 1 long blink of 1.5 seconds to finish the sequence.
• The sequence starts again with 12 short blinks.
5.6.2 How to Activate Blinking LED Procedurer
Use one of the following methods:
• Activate CSM.The blinking front LED will show the layer 1
error(s), this works in "normal operation" mode or
automatically when the error/protection is monitored by the
standby processor.
In case no picture is shown and there is no LED blinking,
read the logging to detect whether "error devices" are
mentioned. (see section
Tips, 5.7.4 Guidelines Uart
• Activate SAM. The blinking front LED will show the entire
content of the LAYER 2 error buffer, this works in "normal
operation" mode.
