Service Modes, Error Codes, and Fault Finding

Connect the AC power adapter to the supply connector
(marked with “POWER 9V DC”) on the ComPair interface.

Switch the ComPair interface OFF.

Switch the television set OFF (remove the AC power).

Connect the ComPair interface cable between the
connector on the rear side of the ComPair interface
(marked with “I2C”) and the ComPair connector on the
mono carrier (see figure 8-1 suffix D).

Plug the AC power adapter in the AC power outlet and
switch on the interface. The green and red LEDs light up
together. The red LED extinguishes after approx. 1 second
while the green LED remains lit.

Start the ComPair program and read the “introduction”
chapter.

Error Buffer

The error code buffer contains all detected errors 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 written at the left side and all other errors shift one
position to the right.

5.4.6

How To Read The Error Buffer

You can read the error buffer in 3 ways:
•

On screen via the SDAM (only if you have a picture).
Examples:
–

ERROR: 0 0 0 0 0: No errors detected

–

ERROR: 6 0 0 0 0: Error code 6 is the last and only
detected error

–

ERROR: 9 6 0 0 0: Error code 6 was first detected and
error code 9 is the last detected (newest) error

•

Via the blinking LED procedure (when you have no
picture). See next paragraph.

•

Via ComPair.

5.4.7

How To Clear The Error Buffer

The error code buffer is cleared in the following cases:
•

By activation of the CLEAR command in the SDAM menu:

•

If the content of the error buffer has not changed for 50
hours, it resets automatically.

Note:
When leaving SDAM by disconnecting the set from AC power,
the error buffer is not reset.

5.4.8

Error Codes

In case of non-intermittent faults, clear the error buffer before
you begin the repair. These to ensure that old error codes are
no longer present.
If possible, check the entire contents of the error buffer. In
some situations an error code is only the result of another error
code and not the actual cause (e.g., a fault in the protection
detection circuitry can also lead to a protection).

The Blinking LED Procedure

Via 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 SDAM is entered, the LED will blink the contents of
the error-buffer.
•

n short blinks (n = 1 - 14),

•

When all the error-codes are displayed, the sequence
finishes with a LED blink of 3 s,

•

The sequence starts again.

Example of error buffer: 12 9 6 0 0
After entering SDAM:
•

12 short blinks followed by a pause of 3 s,

•

9 short blinks followed by a pause of 3 s,
