TheBlinking LED Procedure
Using this procedure, you can make the contentsof the error buffer visible via the front LED.
This is especiallyuseful when there is no picture.
When the SDAM is entered, the LED will blink the contentsof the error-buffer:
z
1-12 shortblinks (indicates error number 1-12)
z
when all the error-codes are displayed, thesequence finishes with an "ON" LED blink of 3
seconds
z
the sequence starts again
Example of error buffer: 12 9 6 0 0
After entering SDAM, the following occurs:
z
12 shortblinks followed by a pause of 3 seconds
z
9 short blinks followed by a pause of 3 seconds
z
6 short blinks followed by a pause of 3 seconds
z
1 long "ON" blink of 3 seconds to finish thesequence
z
the sequence starts again.
Protections
If a fault situation is detected, an errorcode will be generated; and, if necessary, the television
set willgo in to protection mode. Blinking of the red LED at a frequencyof 3 Hz indicates the
protection mode. In some error cases, themicroprocessor does not put the set in protection
mode. The errorcodes of the error buffer and the blinking LED procedure can beread via the
Service Default Alignment Menu (SDAM), or via ComPair.
To get a quick diagnosis the chassis has two service modes implemented:
z
The CustomerService Mode (CSM).
z
The Service Default Alignment Mode (SDAM).
