Service Modes, Error Codes, and Fault Finding
EN 14 L04E AB 5.
Table 5-3 Error codes overview
Note: Errors 7, 8, 13, 14 are not applicable.
5.6
The Blinking LED Procedure
Using this procedure, you can make the contents of the error
buffer visible via the front LED. This is especially useful when
there is no picture.
When the SDM is activated, the LED will blink the contents of
the error-buffer:
•
When all the error-codes are displayed, the sequence
finishes with an 'on' LED blink of 1.5 seconds,
•
The sequence starts again.
Example of error buffer: 12 9 6 0 0
After activating SDM, the following occurs:
•
1 long 'on' 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 'on' blink of 1.5 seconds to finish the sequence,
•
The sequence starts again at 12 short blinks.
5.7
Protections
If a fault situation is detected, an error code will be generated;
and, if necessary, the television set will go into protection
mode. Blinking of the red LED at a frequency of 3 Hz indicates
the protection mode. In some error cases, the microprocessor
does not put the set in protection mode. The error codes of the
error buffer and the blinking LED procedure can be read via the
Service Default Menu (SDM), or via ComPair.
To get a quick diagnosis the chassis has three service modes
implemented:
•
The Customer Service Mode (CSM).
•
The Service Default Mode (SDM).
•
The Service Alignment Mode (SAM).
For a detailed description, see the "Customer Service Mode,
Service Default mode" and "Service Alignment Mode" sections.
