Service Modes, Error Codes, and Fault Finding
EN 13L04.6HU CA 5.
Table 5-1 Error code overview
Note: For all error codes the following applies: error codes are
only valid when the module or device they refer to is used in the
TV set.
5.5 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 entered, the front LED will blink the contents
of the error-buffer:
• When all the error-codes are displayed, the sequence
finishes with a LED blink of 1.5 seconds,
• The sequence starts again.
Example of error buffer: 12 9 6 0 0
After entering SDM, 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 at 12 short blinks.
5.6 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 (Digital) Customer Service Mode ((D)CSM).
• The Service Default Mode (SDM).
• The Service Alignment Mode (SAM).
For a detailed mode description, see the relevant sections.
5.7 Fault Finding and Repair Tips
Notes:
• It is assumed that the components are mounted correctly
with correct values and no bad solder joints.
• Before any fault finding actions, check if the correct options
are set.
5.7.1 NVM Editor
In some cases, it can be handy if one directly can change the
NVM contents. This can be done with the “NVM Editor” in SAM
mode. In the next table, some default NVM values are given.
