ERROR 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.
TO READ ERROR BUFFER
- On screen via the SAM (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 detected first and error code 9 is the last detected (newest) error.
Via the blinking LED procedure (when you have no picture)
TO CLEAR ERROR BUFFER
- By using the CLEAR command in the SAM [Service Alignment Mode] menu:
- To enter SAM, press the following key sequence on the remote control transmitter: “062596” directly followed by the OSD/STATUS button (do not allow the display to time out between entries while keying the sequence).
- Make sure the menu item CLEAR is highlighted. Use the MENU UP/DOWN buttons, if necessary.
- Press the MENU RIGHT button to clear the error buffer. The text on the right side of the “CLEAR” line will change from “CLEAR?” to CLEARED”
- If the contents of the error buffer have not changed for 50 hours, the error buffer resets automatically.
Note:
If you exit SAM
by disconnecting the AC power from the television set, the error buffer is not
reset.
ERROR CODES
- In case of non-intermittent faults, write 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 situations, 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).
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.
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 3Hz 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.
