mains via an isolation transformer.

5.5Error Codes
The error code buffer contains all errors detected since the last
time the buffer was erased. The buffer is written from left to
right. When an error occurs that is not yet in the error code
buffer, it is displayed at the left side and all other errors shift one
position to the right.
The Error Buffer

•Via ComPair.
he Error Buffer
The error code buffer is cleared in the following cases:
•By using the CLEAR command in the SDAM menu:
– To enter SAM, press the following key sequence on the
re
mote control transmitter: '062596' directly followed
by the “OSD" icon button (do not allow the display to
time out between entries while keying the sequence).

– Make sure the m

the MENU UP/DOWN buttons, if necessary.
– Press the MENU RIGH
T button to clear the error
buffer. The text on the right side of the 'CLEAR' line will
change from 'CLEAR?' to 'CLEARED'
down the errors present
in the error buffer and clear the error buffer before you begin
the repair. This ensures that old error codes are no longer
present.
If possible, check the entire contents of the error buffer. In
some situation
s, an error code is only the result of another error
and not the actual cause of the problem (for example, a fault in
the protection detection circuitry can also lead to a protection).

5.6The 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 LED will blink the contents of the
-buffer:

•The sequence starts again.
Example of error buffer: 12 9
After entering SDM, the following occurs:
•1 long 'on' blink of 5 seconds to start the sequence,
•12 short blinks follow
•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.

5.7Protections
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
implemented:
•The Customer Service Mode (CSM).
•The Service Default Mode (SDM).
•The Service Alignment Mode (SAM).
