zthe sequence starts again
Example of error buffer: 12 9 6 0 0
After entering SDAM, the following occurs:
z12 shortblinks followed by a pause of 3 seconds
z9 short blinks followed by a pause of 3 seconds
z6 short blinks followed by a pause of 3 seconds
z1 long "ON" blink of 3 seconds to finish thesequence
zthe 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:
zThe CustomerService Mode (CSM).
zThe Service Default Alignment Mode (SDAM).
